A home spa room with an infrared sauna and cold plunge costs $80,000 to $250,000 depending on sauna brand, cold plunge specification, tile selection, and ventilation. In Joelle Uzyel's Beverly Hills projects, the full build (Clearlight sauna with custom millwork, built-in cold plunge, zellige or stone tile, dual-circuit lighting) typically lands between $130,000 and $180,000. The room is worth it when it is designed as a room, not assembled as equipment.
A dedicated spa room outperforms a spa bathroom in every measure: daily use, habit formation, and resale value.
A well-specified home spa room in Beverly Hills runs $80,000–$250,000. The right target for most projects is $130,000–$180,000.
Clearlight is the infrared sauna brand worth specifying. Everything sold at consumer retail is not built for a designed room.
The cold plunge must be built in. Tiled surround, concealed chiller, within three steps of the sauna exit.
Zellige tile handles thermal cycling better than any ceramic alternative and looks better with age, not worse.
A home spa room with an infrared sauna and cold plunge costs $80,000–$250,000 depending on sauna brand, cold plunge specification, tile selection, and ventilation requirements. In my Beverly Hills projects, the full build: Clearlight sauna with custom millwork, built-in Plunge Craft cold plunge, zellige or stone tile, dual-circuit lighting. It typically lands between $130,000 and $180,000. The room is worth the investment when it is designed as a room, not assembled as equipment, and when the household will use it daily.
A dedicated home spa room is not an add-on. In the Beverly Hills and Bel Air homes I work in, it has become the room clients are most specific about. More than the kitchen. More than the primary suite. The people who live in these houses take recovery seriously, and they have stopped waiting to get to a facility to do it. I built this room for a professional athlete in Beverly Hills. It gets used twice a day. What follows is everything I learned building it right.
Full project costs: design, equipment, materials, labor, mechanical, and installation. These ranges reflect what projects actually cost in the LA market, not catalog estimates.
Tier 1, Functional Entry, $40,000 – $80,000: Single-person infrared sauna (consumer-grade or entry Clearlight), freestanding cold plunge tub, large-format porcelain tile on a steam-rated substrate, single-circuit lighting, basic ventilation. The room works. It does not photograph well and it does not command a premium on resale.
Tier 2, Designed and Built, $80,000 – $130,000: Two-person Clearlight infrared sauna with semi-custom cedar surround, built-in cold plunge with tiled skirt, zellige or stone tile on floor and one feature wall, dual-circuit lighting on dimmers, properly sized ventilation. This is the entry point for a room that looks like it belongs in the house.
Tier 3, Full Custom, $130,000 – $200,000: Clearlight sauna fully integrated into site-built cedar millwork, built-in Plunge Craft cold plunge in full zellige or stone surround floor to ceiling, red light therapy panel on dedicated circuit, steam shower, dual-zone lighting with Lutron, concealed mechanical, built-in bench moment. The Beverly Hills standard for this room.
Tier 4, Destination Room, $200,000 – $350,000+: Fully custom specification: imported stone, automated climate and lighting, spa-facility-level filtration and water chemistry for the cold plunge, custom scent and sound integration. Built for households where recovery is a professional priority and the room is a signature of the home.
Sauna unit and millwork: The sauna unit is 20–30% of the total budget, but the millwork surround is what separates a designed room from an equipment room. A Clearlight unit runs $4,500–$9,000 depending on configuration. The cedar millwork integration: custom framing, integrated benching, concealed controls, matching trim. It adds $8,000–$15,000. Do not skip the millwork. It is the difference between a room and a purchase.
Cold plunge installation: A freestanding cold plunge costs $3,000–$8,000. A built-in cold plunge with a tiled surround, concealed chiller, and proper plumbing runs $20,000–$45,000. The difference is entirely visual and entirely worth it. In the Beverly Hills market, a built-in cold plunge reads as permanent infrastructure. A freestanding unit reads as furniture you might move.
Tile and stone selection: Zellige tile runs $35–$85 per square foot installed. More than standard porcelain, less than imported stone. For a 400-square-foot room tiled floor to ceiling, that is a $28,000–$68,000 decision. Large-format porcelain at $18–$35 per square foot installed is the rational alternative. The visual difference is significant. Zellige ages beautifully with heat. Porcelain does not age at all, which is either a feature or a liability depending on the room.
Mechanical infrastructure: Ventilation, HVAC zoning, plumbing, and dedicated electrical for a spa room run 15–20% of total project cost in LA. This is the line item clients most often try to cut and most often regret cutting. Undersized ventilation means a room that never fully dries between uses. Shared electrical circuits mean performance inconsistency in the sauna. Both problems are expensive to fix after the tile is in.
The decision that cannot wait: Floor drain location. If the floor drain is not placed correctly at design inception, every downstream decision is compromised: tile layout, cold plunge position, shower location, sauna orientation. I have watched contractors pour concrete over a misplaced drain because the client wanted to save the redesign fee. The redo cost three times the fee they were avoiding.
The room that gets used every day is the room that has its own door.
The question I get is always: can you work the sauna into the master bathroom? The answer is no. Not if you want the room to actually be used. A sauna in a bathroom is a sauna that gets turned off when someone needs to shower. The daily friction of sharing infrastructure with morning routines means the sauna becomes a twice-a-week novelty instead of a daily practice.
A dedicated room solves this completely. The sauna is always preheating. The cold plunge is always cold. The room has its own HVAC zone, its own lighting scene, its own entry ritual. That separation is what makes the habit stick. It is also what makes the room worth the square footage on resale. A spa room that functions like a real spa commands a premium that a sauna-in-a-bathroom does not.
The minimum footprint I work with is 300 square feet. That gives you a two-person sauna, a built-in cold plunge, a shower transition, and a cedar bench wall with room to sit and breathe. My preferred footprint is 400–500 square feet. Enough for a red light therapy installation, proper seating, and the spatial generosity that separates a wellness room from a very expensive bathroom renovation.
On a $165,000 project, the budget breaks down as follows: Tile, stone and installation takes 24% ($39,600). The sauna unit plus cedar millwork takes 22% ($36,300). Mechanical work, HVAC, plumbing, and electrical takes 20% ($33,000). The cold plunge plus built-in surround takes 18% ($29,700). Lighting, fixtures, and hardware take 11% ($18,150). Design services take 5% ($8,250).
A professional athlete client came to me with a specific brief: they wanted the same recovery infrastructure their team facility had, built into their home, designed so it did not look like a training room. That last requirement was the interesting one. The room needed to function at an elite level: daily sauna, daily cold plunge, red light protocol. And it needed to read visually as a spa, not a facility.
I used Clearlight for the sauna, integrated into custom cedar millwork so it reads as a room feature, not a unit that was moved in. The cold plunge is a built-in Plunge Craft tub set into a zellige tile surround that runs floor to ceiling on the adjacent wall. The lighting runs on two circuits: a bright functional layer for entry and cleaning, and a low amber layer for active recovery sessions. Scent is introduced through the steam transition zone. Sound is built into the ceiling and invisible.
The room gets used twice a day. That is the only benchmark I design toward. A room that photographs well and sits unused is a liability. A room that changes how someone recovers, trains, and sleeps is infrastructure.
Clearlight is worth the cost. Everything sold at consumer retail is hardware wearing a wellness badge.
Design the room before you buy the sauna. Every client who buys the sauna first creates a constraint problem. The unit arrives, and suddenly ceiling height, electrical capacity, ventilation routing, and floor drain placement are all locked in around a box that was not spec'd for the space. Start with architecture. Select the unit last.
Do not value-engineer the cold plunge surround. The cold plunge unit is $3,000–$8,000. The surround is where the room either looks finished or does not: tile, structure, concealed plumbing, chiller housing. Cutting the surround to save $12,000 produces a room worth $40,000 less on resale. It is the most common budget decision I see clients reverse.
Plan for 6–8 months, not 3–4. The Clearlight sauna has an 8–14 week lead time. Zellige tile from Morocco runs 10–16 weeks. Plunge Craft is 6–10 weeks. These items must be ordered at design inception, not when construction starts. The projects that finish on time are the ones where procurement and construction run in parallel from week one.
One designer. Full coordination. No fragmentation. A spa room requires the sauna installer, the tile contractor, the plumber, the electrician, and the HVAC contractor to work in a precise sequence. When a client manages those relationships independently, the sequence breaks. I have rebuilt more than one spa room where a single sequencing error cost $25,000–$40,000 to correct. It is always the drain. It is always avoidable.
Buying the sauna before designing the room: The unit arrives and every design decision is now constrained by a box that was not spec'd to the space. Floor drain location, electrical capacity, ceiling height, ventilation routing: all of it should precede the purchase. The reverse order costs money and produces a room that always looks retrofitted.
Freestanding cold plunge in a finished space: A consumer cold plunge unit in a designed room reads as unfinished regardless of brand. In the Beverly Hills market, a freestanding tub without a surround is the visual equivalent of a clawfoot tub with no tile. Build it in. Tile the surround. Conceal the chiller. It is a fixture, not an appliance.
One lighting circuit: Functional use and active recovery require completely different light levels. A single circuit means the room is either too bright for sauna use or too dim for cleaning and safety. Two circuits on separate dimmers is the minimum. Three is correct: functional overhead, ambient wall, and red light therapy on its own circuit.
Undersized ventilation: A spa room generates significant moisture and heat simultaneously. Ventilation spec'd for a standard bathroom produces a room that never fully dries between uses. Mold follows within 18 months. The mechanical engineer on this room should be sizing for a commercial steam environment, not a residential bathroom.
No transition zone between sauna and plunge: The protocol requires a physical rhythm between the sauna exit and the cold plunge entry: heat exposure, cold exposure, rest, repeat. Without a bench, a towel hook at the right height, and two to three steps of intentional space, the transition feels clinical and the habit breaks. The transition zone is what makes recovery feel like a ritual.
Skipping the cedar millwork on the sauna unit: A sauna unit without a millwork surround reads as equipment. It photographs poorly, it does not command a resale premium, and it makes the room feel like a converted utility space regardless of how good the tile is. The cedar surround costs $8,000–$15,000. It is not optional if design outcome matters.
My background is in real estate development, not decoration. I approach every room as an investment decision first. That means structural requirements, resale performance, and long-term maintenance before tile. A home spa room built by a decorator and a home spa room built by a designer with development experience are completely different outcomes. One photographs well. The other performs well for twenty years.
The spa room I built for a professional athlete in Beverly Hills gets used twice a day. That is the benchmark I design toward. Rooms that look designed but sit unused are expensive mistakes. Rooms that function at an elite level and look like they belong in the house are the ones that change how you live in it. And that command a premium when you sell.
A well-designed home spa room with an infrared sauna runs $80,000–$250,000 depending on sauna brand, cold plunge specification, tile work, and ventilation requirements. In my Beverly Hills projects, the full build typically lands between $130,000 and $180,000: Clearlight sauna, custom cold plunge, zellige or stone tile, steam-rated lighting. The room itself is the investment. The sauna unit is only part of the cost.
Clearlight is the brand I specify on high-end residential projects. The build quality holds up in a designed room, the EMF ratings are among the lowest in the industry, and the cabinetry integrates cleanly into custom millwork. For clients who want a more architectural look, Sunlighten is the other worth considering. Avoid brands sold at big-box retailers. They are consumer units designed to sit in a garage, not a spa room.
Infrared is better for most home installations. It heats the body directly rather than the room air, which means lower operating temperatures (120–150°F vs 180–195°F for traditional), dramatically lower electrical and ventilation requirements, and faster warm-up times. Traditional steam saunas deliver a more intense experience and are worth the added infrastructure for serious users. For a professional athlete or daily recovery user, I often spec both: the infrared sauna for daily use and a steam shower for longer sessions.
A functional home spa room needs a minimum of 300 square feet to house a two-person sauna, a cold plunge, a shower transition, and seating with room to move. My preferred footprint is 400–500 square feet. Enough to add a red light therapy installation, a proper seating area, and the spatial breathing room that separates a wellness room from a converted closet. Below 250 square feet, the room functions but never photographs well and feels cramped in daily use.
Zellige tile and large-format stone are the two materials I use most in spa rooms. Zellige handles the thermal cycling from sauna heat to cold plunge splashing better than most ceramic options and looks significantly better as it ages. The heat deepens the surface variation rather than degrading it. Large-format porcelain reads cleaner and more architectural but requires precision installation on steam-rated substrate. Glass tile shows water spots constantly. I avoid it in rooms built for daily use.
A cold plunge is a tub maintained between 39–55°F for cold water immersion therapy. It is the counterpart to heat exposure in a sauna protocol. In a designed spa room, the cold plunge is treated as a fixture, not an appliance: built into a tiled surround, sized for the room, and plumbed like a custom tub. Plunge Craft and BlueCube are the brands I use most for residential installations. The cold plunge should sit within three steps of the sauna exit. The protocol requires rapid alternation between heat and cold.
Yes, when it is designed correctly. A spa room that looks like a designed space adds meaningful value in the Beverly Hills and Bel Air market because buyers at that price point expect wellness infrastructure. A poorly designed room with consumer-grade equipment actually works against you on resale. The difference between a room that adds value and one that does not is entirely in the design execution.
Plan for 6–8 months from design kick-off to a finished room. The sauna unit alone has an 8–14 week lead time depending on brand and configuration. Zellige tile from Morocco runs 10–16 weeks. Tile, plumbing, and electrical all need to be rough-in complete before the sauna is installed. In my projects, I run design and procurement in parallel so tile and fixtures arrive when the space is ready. It compresses the timeline without rushing the work.
