The difference between a bathroom and a spa is not the size of the budget. It is the intentionality of the design. Some of the most effective spa bathroom transformations we have completed at First Choice Home Builders cost less than $35,000. Some of the most expensive bathrooms we have seen feel like nothing more than expensive versions of a generic layout.
What creates a spa experience in a bathroom is a specific combination of sensory conditions: warmth underfoot, the sound of water, natural materials that feel substantial in the hand, diffused light that does not create harsh shadows, and above all else the absence of visual clutter. A spa bathroom is a place where the mind slows down. Every design decision should serve that goal.
San Diego homeowners have a particular advantage when designing spa bathrooms. The climate allows for open-concept bathrooms with connections to private outdoor space, natural light is generous in most San Diego homes, and the region's affinity for natural materials and indoor-outdoor living translates directly into the warm, organic aesthetic that defines the best spa bathroom design.
This guide covers everything: the design philosophies that create a genuine spa experience, the specific features that deliver the highest daily return, the materials that age beautifully in San Diego's climate, and the real costs across every tier of investment.
What Actually Makes a Bathroom Feel Like a Spa
Before focusing on specific features, it helps to understand what spa bathrooms do that standard bathrooms do not. The difference is not a checklist of luxury features. It is a set of design principles applied consistently.
Sensory Warmth
Cold tile underfoot in the morning is the opposite of a spa experience. Heated floors, warm-toned materials, and materials that feel substantial in the hand (stone, wood, thick towels) create physical warmth that signals comfort before a single fixture is used. Temperature is the first and most immediate sensory signal in any space.
Visual Calm
A spa bathroom has nothing extraneous in the sightline. Every surface is clean. Products are stored out of sight. The visual palette is restrained, typically three materials or fewer. When you walk in, the eye finds nothing to snag on and the mind follows the eye into a state of ease. This is not an accident. It requires disciplined design choices and built-in storage that actually works.
Natural Materials
Stone, wood, and natural fiber create a sensory environment that synthetic materials cannot replicate. The texture of honed travertine, the warmth of teak, and the scent of natural materials contribute to the spa experience in ways that porcelain tile, laminate, and plastic fixtures do not, even when those materials are technically excellent. In a spa bathroom, the materials are doing emotional work as well as functional work.
Water as a Feature
In a standard bathroom, water is a utility. In a spa bathroom, water is an experience. A rain head that delivers water from directly overhead, body jets that provide targeted pressure, a deep soaking tub that allows full immersion, and a steam system that fills the shower with humid warmth all transform the functional act of bathing into a genuinely restorative experience.
Light That Flatters
Harsh overhead lighting is the enemy of the spa experience. Layered lighting with vanity lights at eye level, dimmable recessed lights, and accent lighting that illuminates surfaces rather than people creates the soft, flattering quality of light that makes a bathroom feel luxurious. No amount of expensive tile compensates for lighting that makes everyone look terrible.

The 10 Features That Define a Spa Bathroom
Large Curbless Walk-In Shower
The shower is the heart of a spa bathroom and the feature that delivers the most daily return on investment. A curbless (zero-threshold) walk-in shower with no door barrier, or a frameless glass enclosure, creates the visual openness of a resort spa. Minimum recommended size for a true spa shower is 48x48 inches. 60x36 or larger is ideal. The zero threshold is not just an accessibility feature. It creates a visual continuity between the shower and the bathroom floor that makes the whole room feel larger.
Ceiling-Mounted Rain Head Shower
A rain head mounted directly in the ceiling delivers water from above across the full width of the shoulders, mimicking natural rainfall. The experience is categorically different from a wall-mounted shower head and is the single most requested spa upgrade in our primary bathroom projects. The ideal rain head is 10 to 14 inches in diameter, mounted flush in the ceiling, and controlled by a thermostatic valve that allows presetting the temperature so the shower is ready the moment you step in.
Radiant Heated Floor
An electric radiant heat mat installed under tile is the most universally loved spa bathroom feature among our clients. It activates a few minutes before you step out of the shower or tub, warming the tile to 72 to 80 degrees. In San Diego's mild climate, the system runs only 20 to 30 minutes per day during the cooler months, making operating costs minimal. The daily experience of stepping onto a warm floor is one of the most effective comfort upgrades available at any budget level. A smart thermostat allows scheduling warmth by time of day.
Freestanding Soaking Tub
A freestanding tub is the most visually dramatic element in any spa bathroom. Positioned as a deliberate focal point, often centered under a window or skylight, it communicates luxury immediately and photographs exceptionally well. Contemporary favorites in San Diego in 2026 include matte white resin tubs in an oval or asymmetric form, stone cast composite tubs in warm gray or ivory, and sculptural acrylic tubs with waterfall filler spouts. Soaking depth is the functional measure that matters: look for tubs with at least 18 to 22 inches of interior depth for true full-body immersion.
Steam Shower
A steam generator added to a fully enclosed shower creates a personal steam room. Steam therapy has well-documented benefits for respiratory health, muscle relaxation, and skin hydration. In San Diego's dry autumn and inland conditions, steam is particularly welcome. The generator is installed in a remote cabinet (often in the vanity toe space or adjacent closet) and pumps steam through a ceiling-mounted head in the shower. A proper steam shower requires a completely sealed enclosure (glass door, not open walk-in), a ceiling slope to prevent condensate drips, and a steam-specific bench for seated use.
Thermostatic Shower System with Body Jets
A thermostatic shower valve presets and maintains exact water temperature independently of pressure fluctuations, which means the shower is precisely the temperature you set the moment you turn it on, every time. Paired with body jets at shoulder and lower back height, it creates a multi-directional hydrotherapy experience that a standard shower cannot replicate. Brands like Kohler DTV, Hansgrohe RainSelect, and Grohe provide integrated digital controls that manage rain head, body jets, and handheld from a single touchpad.
Backlit Mirror with Integrated Defog
A large LED backlit mirror or full-height mirror with integrated lighting creates the soft, halo-quality light that makes a vanity area feel like a high-end hotel bathroom. Integrated defog heating eliminates the post-shower fog problem without a separate defogger unit. Backlit mirrors with built-in dimmers, color temperature adjustment (cooler for morning makeup, warmer for evening relaxation), and Bluetooth speakers are available from brands like Kohler, Robern, and Electric Mirror. A well-sized backlit mirror (at least as wide as the vanity) is one of the highest-impact visual upgrades in a spa bathroom at a relatively accessible price point.
Floating Double Vanity with Integrated Lighting
A wall-mounted double vanity at 60 to 72 inches wide creates the symmetrical, organized focal wall that is central to the spa bathroom aesthetic. The floating installation exposes the floor beneath, creating visual breathing room. Integrated LED strip lighting under the vanity provides a soft ambient glow at floor level, particularly striking at night. Drawer and cabinet organization inserts keep the counter surfaces entirely clear, which is essential to maintaining the spa visual. A Kohler, Strasser, or custom semi-custom vanity in a matte finish, paired with a continuous quartz or stone countertop and integrated undermount sinks, creates a seamless surface with no visual breaks.
Natural Stone or Large-Format Tile Throughout
Consistent tile from floor through shower walls and, where possible, across the vanity wall creates the visual continuity that characterizes resort and hotel spa bathrooms. Using the same material in a large format, 24x48 or 32x32 inch porcelain, reduces grout lines to a minimum, which both simplifies cleaning and creates a surface that reads as one continuous plane rather than a grid of individual tiles. The material choice matters enormously. Honed marble, travertine, and quartzite have a depth and warmth that no porcelain fully replicates, though premium stone-look porcelain from Italian manufacturers like Fiandre, Atlas Concorde, or Porcelain Plus has closed the gap significantly.
Private Outdoor Connection
San Diego's climate makes a private outdoor connection from the primary bathroom one of the most distinctive and achievable luxury features available to local homeowners. A glass door or floor-to-ceiling window opening onto a private garden, an enclosed courtyard, or an outdoor shower creates a seamless relationship between interior bathing and the outdoors that is not possible in most other US climates. An outdoor shower fed from the primary bathroom's plumbing, surrounded by privacy screening of bamboo, wood slat fencing, or garden walls, adds a genuinely unique experience that no interior feature can replicate. Cost for an outdoor shower connection and privacy enclosure: $4,500 to $14,000 depending on complexity.
The Shower: Foundation of the Spa Experience
If there is one element to invest in without compromise in a spa bathroom, it is the shower. The shower is used every day, sometimes twice. The soaking tub is used occasionally. The shower is where the daily experience of the bathroom is actually lived, and every dollar invested in shower quality and design delivers ongoing daily return.
Shower Size
The minimum shower size we recommend for a spa experience is 48x36 inches. Below this, the rain head cannot deliver full-body coverage without the spray rebounding off the walls onto the user. A 60x36 or 48x48 inch shower is comfortable for one person with a rain head and handheld. For couples sharing the shower or for an elaborate multi-head system, 60x60 or larger is ideal. In a primary bathroom remodel, eliminating the underused bathtub to gain shower space is almost always the right design decision.
Shower Tile Selection
The shower is the largest tiled surface in most bathrooms and sets the visual tone for the entire space. For a spa shower, we recommend:
- Floor: Smaller format tile (2x2, mosaic, or penny tile) in a natural stone or stone-look material for slip resistance and visual texture. The floor is where texture is welcome because it provides grip. Coordinate with the larger format field tile for a cohesive look.
- Walls: Large-format tile (24x24 or 12x24 minimum) to reduce grout lines and create an expansive, uninterrupted surface. Honed finish rather than polished for a more spa-appropriate matte quality.
- Accent: One niche tiled in a contrasting material (a slab of book-matched marble, a row of zellige, or a handmade ceramic) creates a focal point without overwhelming the design.
Shower Hardware Finish
In 2026, the most popular hardware finishes for spa bathrooms in San Diego are brushed gold, matte black, and brushed nickel in roughly equal proportion. Polished chrome has declined significantly as a primary finish choice. Brushed gold adds warmth and luxury associations. Matte black reads as contemporary and graphic. Brushed nickel is the most versatile and works across the widest range of material palettes. Whatever finish is chosen must be consistent across the shower valve, rain head, handheld, body jets, towel bars, faucets, and door hardware.
Freestanding Soaking Tub: The Statement Piece
The freestanding soaking tub has become the defining visual element of the luxury primary bathroom. It is the feature that most immediately communicates that this is not a standard bathroom. It photographs as a focal point in every listing photo. And for homeowners who actually use it, it delivers a genuinely restorative bathing experience that a standard alcove tub cannot approach.
Tub Materials
- Acrylic: Lightest weight, widest variety of forms, retains heat moderately well. Entry-level luxury. Brands: Kaldewei, MTI, American Standard. Cost: $1,200 to $3,500 for the tub.
- Cast stone composite: Heavier, retains heat significantly better than acrylic, warm tactile quality. Mid-range luxury. Brands: Victoria + Albert, Stone Forest, Wet Style. Cost: $3,000 to $8,000.
- Cast iron: Exceptional heat retention, extremely durable, very heavy (300 to 500 lbs, requiring structural support). Classic luxury. Brands: Kohler, American Standard. Cost: $2,500 to $7,000.
- Natural stone: Carved from a single stone block (marble, granite, onyx). Maximum luxury and visual impact. Unique, heavy, requires structural engineering. Cost: $8,000 to $35,000+.
Tub Placement
The freestanding tub performs best as a deliberate focal point rather than an afterthought. Ideal placement is centered under a window that provides natural light and a view (of a garden, the sky, or a private courtyard), away from the primary traffic path through the bathroom, with enough clear floor space around it (18 to 24 inches on all sides) to move around comfortably. The floor drain under a freestanding tub must be planned during the plumbing rough-in phase, not added later.
Radiant Heated Floors
Electric radiant floor heating is installed as a thin mat of resistance heating cable embedded in thinset mortar under the tile. It adds approximately 3/8 inch to the floor height, which must be accounted for in door clearances and transition heights during the design phase. The mat connects to a programmable thermostat that allows scheduling warmth by time of day and day of week.
In San Diego, a typical primary bathroom floor runs 50 to 80 square feet. At an operating cost of approximately $0.12 to $0.18 per hour of operation (based on SDG&E's 2026 residential rates), a 45-minute daily warm-up cycle costs roughly $2.50 to $4.00 per month, which is negligible for the experience delivered. The installation cost of $1,800 to $5,500 for a primary bathroom is one of the best value investments in any spa bathroom remodel.
Radiant floor heating can only be installed when the floor tile is being replaced. Adding it later requires removing all existing tile, installing the heating mat, and retiling, which costs nearly as much as the original installation. If you are ever doing a bathroom tile replacement and have not already considered heated floors, this is the moment. Adding heated floors during an existing tile project typically adds $1,200 to $3,500 to the scope, which is far less than a standalone installation would cost.
Steam Shower
A steam generator system converts a fully enclosed shower into a personal steam room. The generator heats water to produce steam, which enters the shower through a steam head typically mounted near the floor (where steam rises most effectively). A digital control panel allows setting temperature, duration, and optional aromatherapy injection for eucalyptus or other essential oils.
Steam Shower Requirements
A steam shower requires a fully sealed enclosure (no open walk-in format), a sloped ceiling (minimum 8-degree pitch toward a non-user-facing corner to prevent condensate from dripping onto the user), a steam-rated bench for seated use, and a generator sized to the shower volume (typically 7.5 to 10 kW for a standard primary bathroom shower). The generator requires a dedicated 240-volt electrical circuit and should be located within 25 feet of the shower for efficient steam delivery.
Steam vs Dry Sauna
Some San Diego homeowners with larger primary suites consider a compact sauna in lieu of or in addition to a steam shower. A pre-built infrared sauna cabinet (2-person) can be installed in a primary suite closet or alcove for $3,500 to $8,000, requires only a standard 120-volt circuit, and delivers a different (dry heat) therapeutic experience than steam. Both have loyal enthusiasts. The steam shower integrates invisibly into the bathroom. The sauna requires dedicated floor space.
Vanity, Lighting, and Mirrors
Double Vanity Design
A spa bathroom vanity serves two functions: it organizes the bathroom and it creates the anchor of the design. For a primary bathroom with two occupants, a 60 to 72 inch double vanity with two sinks and designated storage zones for each person eliminates the most common source of daily friction in a shared bathroom. Asymmetric storage assignments, such as all drawers on one side and all cabinets on the other, can reflect the different storage needs of each user.
The countertop material ties the vanity to the overall tile palette. A continuous slab of quartz, Calacatta marble, or quartzite with integrated undermount sinks and no visible seams is the definitive luxury vanity surface. Where the budget does not support full-slab stone, a premium quartz engineered to mimic the look is a practical alternative.
Layered Lighting
Spa bathroom lighting requires three layers:
- Task lighting: Vertical sconces at eye level flanking the mirror, or a horizontal LED vanity bar at face height. This eliminates shadows under the chin and nose that overhead lighting creates. The most important lighting decision in any bathroom.
- Ambient lighting: Dimmable recessed lights in the ceiling providing overall illumination. Controlled separately from task lighting so that the bathroom can be lit for grooming or dimmed for a relaxing bath.
- Accent lighting: Under-vanity LED strips for floor-level ambient glow, lighting inside niches to highlight decorative objects, and lighting that grazes the texture of stone tile walls to accentuate the material's natural variation.
Mirror Selection
For a double vanity, a single large mirror spanning the full width of the vanity is more elegant and makes the room feel larger than two individual mirrors. A backlit edge-lit mirror provides both task lighting and ambient glow in a single fixture. For a classic spa look, a framed mirror in a warm material (unlacquered brass, matte black metal, or natural wood) creates a finished quality that a frameless mirror does not.
Materials: Tile, Stone, and Wood
The material palette is the most lasting decision in a spa bathroom. Unlike fixtures that can be swapped out, tile and stone are essentially permanent for the life of the remodel. Choose materials that will age well, that you will not tire of, and that suit San Diego's indoor-outdoor lifestyle.
Warm ivory and cream. Natural variation. Stays cool underfoot. Requires sealing every 3 to 5 years. San Diego classic.
White base with dramatic gray or gold veining. Elegant and timeless. Higher maintenance. Statement pieces or feature walls.
Large-format stone-look. Zero maintenance. Durable. Best option for whole-bathroom coverage without sealing requirements.
Natural stone with marble aesthetics but granite durability. More resistant to etching than marble. Premium choice for countertops and feature surfaces.
Naturally water-resistant hardwood for shower benches, bath caddies, and floating shelves. Requires periodic oiling. Warm and organic.
Handmade Moroccan tile with natural color variation and texture. Used as an accent in niches or single walls. Artisanal quality at a premium price.
Smart Bathroom Technology
Technology in a spa bathroom should be invisible when not in use and effortless when in use. The goal is not a demonstration of gadgetry but a seamless experience.
Thermostatic Shower Controls
Digital thermostatic controls from Kohler (DTV+), Hansgrohe, or Moen allow presetting exact shower temperature, activating specific shower heads independently, and saving personal preferences for each household member. The shower starts at the right temperature before you step in, every time. This is the single most impactful technology upgrade in any spa shower.
Smart Heated Floor Thermostat
A WiFi-connected floor thermostat from Warmup or nVent Nuheat allows programming warm floors by time of day and day of week, monitoring energy use, and controlling from a smartphone. Wake up at 6:30 AM Monday through Friday and the floor is warm at 6:28 AM. This is the definition of effortless technology.
Voice-Controlled Lighting
Integration of bathroom lighting with a smart home system (Apple HomeKit, Google Home, or Amazon Alexa) allows voice control of lighting scenes, dimming, and color temperature. "Morning bathroom" at full brightness, "bath time" at 20 percent warm, controlled without touching a switch when your hands are full.
Smart Toilet
Japanese-style smart toilets (TOTO Washlet, Kohler Veil) with integrated bidet, heated seat, automatic lid, and warm air dryer are increasingly common in San Diego luxury bathrooms. They combine hygiene, comfort, and sustainability in a single fixture. Entry-level smart toilet seats that add bidet function to an existing toilet start at $500 to $1,200. Full smart toilet units run $1,500 to $5,500.
Spa Storage and Organization
The spa experience is destroyed by visual clutter. A beautiful tile shower with shampoo bottles lined on the edge of the tub, a double vanity with products scattered across the counter, and a linen closet overflowing into the bathroom all undermine everything the design achieves. Storage in a spa bathroom must be sufficient, organized, and invisible.
Built-In Shower Niches
Two to three built-in niches in the shower eliminate the need for any external storage. One at shoulder height for daily use products, one at knee height for foot care, and a larger niche for extra product storage. Tiled in a contrasting accent material or lit with a recessed LED, niches become design features rather than utilitarian additions.
Vanity Drawer Organization
Deep drawers with custom dividers, pull-out trays, and vertical dividers for hair tools allow the vanity counter to be entirely clear at all times. Every product has a home inside the drawers. The counter holds only the items in active use at that moment. Custom drawer organization inserts cost $200 to $600 per vanity and are the most practical detail investment in any bathroom.
Linen Storage
A built-in linen tower adjacent to the vanity, a recessed linen cabinet in a wall cavity, or a small closet accessible from within the bathroom keeps towels and linens at hand without cluttering the bathroom floor. Rolled towels displayed in an open niche is the spa hotel reference point that many clients ask for and delivers both function and visual richness.
Color Palette and Atmosphere
Spa bathrooms in San Diego in 2026 are almost universally warm and neutral, not cool and clinical. The cool gray and white palette that dominated bathroom design in the early 2010s has given way to warmer tones that reflect the organic materials and indoor-outdoor connection of California living.
The most effective spa bathroom palettes use three materials or fewer and three tones or fewer. A warm white tile field, a cream-toned stone countertop, and a natural wood accent. A gray-beige large-format porcelain floor, a warm white shower wall, and matte black fixtures. The restraint in material selection is what creates the visual calm that is the defining quality of a spa experience. More materials, more colors, and more patterns create visual noise that no amount of expensive fixtures can overcome.
In a primary bathroom under 80 square feet, using one dominant tone throughout, the same warm beige or warm white on the floor, shower walls, and vanity countertop, creates a room that feels significantly larger than its dimensions and deeply calm. Introduce one accent material (teak, matte black hardware, brass fixtures) to prevent the palette from feeling flat. This is the design principle behind the most effective boutique hotel bathrooms and it works in residential San Diego bathrooms of any size.

San Diego-Specific Considerations for a Spa Bathroom
Coastal Humidity and Material Selection
San Diego's coastal neighborhoods experience morning marine layer humidity that can accelerate mold and mildew in bathrooms with inadequate ventilation. Exhaust fans in a spa bathroom should be sized generously (at least 110 CFM for a primary bathroom, more for bathrooms with steam showers). Grilles from Broan, Panasonic, or Delta that are whisper-quiet and humidity-sensing automatically run until post-shower humidity is cleared. Tile grout should be sealed with a premium grout sealer annually in coastal homes.
Water Efficiency
California's water use regulations apply to fixtures sold and installed in San Diego. Low-flow shower heads must meet California's 1.8 GPM maximum (federal standard is 2.5 GPM). Many premium rain heads and thermostatic systems now incorporate water-efficient flow restrictors that maintain the sensation of volume through air entrainment without exceeding the flow rate limit. Confirm that all shower fixtures are California-compliant before purchasing, particularly for imported European fixtures.
Natural Light and Privacy
San Diego's generous natural light makes skylights, high clerestory windows, or frosted glass windows particularly effective in spa bathrooms. A skylight over the soaking tub, bringing natural light and star-gazing potential directly to the bathing experience, is one of the most consistently appreciated features in our primary bathroom projects. Privacy glazing on standard windows allows natural light without compromising privacy and is significantly less expensive than a full skylight installation.
A La Jolla client engaged First Choice Home Builders for a complete primary bathroom transformation in a 1980s home. The original bathroom was 85 square feet with an outdated jacuzzi tub, a step-in shower, and original tile. We removed the jacuzzi, expanded the shower to 60x60 inches with a ceiling rain head, steam generator, and body jets, installed honed travertine throughout, added a freestanding Japanese-style soaking tub under a new skylight, installed a 72-inch floating double vanity in white oak with a continuous quartzite slab, added radiant heated floors, and connected the bathroom to a newly added private garden courtyard with an outdoor shower. Total project cost: $118,000. The clients describe it as the single best investment they have made in the 18 years they have owned the home.

How much does a spa-like bathroom remodel cost in San Diego?
A mid-range spa bathroom remodel in San Diego costs $28,000 to $55,000, delivering a large walk-in shower with rain head, radiant heated floors, frameless glass, floating vanity, and quality tile. A high-end spa bathroom with natural stone throughout, steam shower, thermostatic system, and premium freestanding tub runs $55,000 to $90,000. A full luxury primary suite transformation costs $90,000 to $150,000 or more depending on size and finishes.
What makes a bathroom feel like a spa?
The spa experience comes from sensory warmth (heated floors, warm materials), visual calm (minimal clutter, restrained palette), natural materials (stone, wood, natural tile), water as a feature (rain head, deep soaking tub), and soft layered lighting. The absence of clutter is as important as the presence of luxury features. A beautifully designed bathroom with products scattered on every surface does not feel like a spa regardless of the fixture quality.
What is the single most impactful spa bathroom feature?
Radiant heated floors deliver the highest daily perceived luxury per dollar of any spa bathroom feature. The experience of stepping onto warm tile is immediate, physical, and noticed every single morning. A ceiling-mounted rain head shower is the most impactful single fixture upgrade. Together, these two features form the experiential foundation of any spa bathroom at any budget level.
Is a freestanding tub worth it?
A freestanding soaking tub is worth the investment for homeowners who genuinely enjoy baths. It is the most visually dramatic element in a spa bathroom, photographs beautifully, and delivers a genuinely restorative bathing experience when used. For homeowners who rarely take baths, investing that budget into a larger, more elaborate shower delivers more daily return. Be honest about your bathing habits before committing $5,000 to $12,000 to a tub installation.
What tile looks most like a spa?
Large-format natural stone or stone-look porcelain in warm neutral tones creates the most spa-like atmosphere. Honed travertine, warm white or beige marble-look porcelain, and light warm gray large-format tile are the most effective spa bathroom materials in San Diego in 2026. Using the same tile continuously from floor through shower walls creates the visual continuity that characterizes resort spa bathrooms. Minimize grout lines by using the largest format tile your space can support.
How long does a spa bathroom remodel take?
The construction phase of a primary bathroom spa transformation takes 4 to 7 weeks. The total timeline including design, material selection, permitting, and lead times for specialty tile and fixtures is typically 16 to 28 weeks from initial consultation to completed bathroom. Natural stone and custom cabinetry have the longest lead times. Begin planning at least 4 to 6 months before your target completion date.
Does a spa bathroom remodel add value to a San Diego home?
Yes. A well-executed primary bathroom spa transformation is one of the highest-impact improvements for San Diego home resale, particularly at price points above $800,000 where buyers expect a primary bathroom that reflects the home's overall quality. An upscale primary bathroom remodel returns approximately 55 to 65 percent of cost at resale on a financial basis, but its impact on days on market, buyer competition, and negotiating position frequently generates more total value than the percentage alone suggests.
