Commercial Saunas
Heavy-use sauna and steam rooms for gyms, climbing gyms, wellness studios, co-ops and boutique hotels, built with commercial heaters, cleanable surfaces, accessible layouts and the inspections a public facility needs.
Rooms that run twelve hours a day
A home sauna might be heated five times a week. A sauna at a gym off Gilman or a wellness studio on College Avenue can run from opening to close, with the door swinging every few minutes and a hundred bodies on the benches by evening. Everything in a commercial room is chosen for that load: heaters with commercial ratings, heavier bench stock, surfaces that take a daily scrub, and controls staff can run without reading a manual.
We build dry saunas, steam rooms and hot and cold suites for gyms, climbing gyms, yoga and wellness studios, boutique hotels, housing co-ops and small spas. A lot of Berkeley commercial space sits in older mixed-use buildings with tenants above, so we watch how heat, humidity and sound travel into the neighbors. Commercial service is often three-phase, and we bring your building engineer or landlord in from the first meeting.
Some operators want the lower running cost and gentler warmth of infrared saunas for booked private sessions. Others want a classic hot room tucked into a basement or back-of-house space, which follows the same sealing rules as our indoor saunas, only with heavier specs.
Why operators bring in a licensed builder
A public sauna answers to more people: the building department, sometimes the county health department, the fire marshal, your insurer and eventually your members. We plan for all of them from the start. The shop behind our sauna builder services for home and business has been building heat rooms for over a decade, and on commercial jobs we phase the work around your hours.
- We specify heaters and controls rated for commercial duty cycles.
- We lay out entries, clear floor space and bench heights with accessibility in mind.
- We include timers, posted safety signage and outward-swinging doors with no locks.
- We pick finishes that stand up to daily cleaning with approved products.
- We coordinate with Alameda County Environmental Health when shared water features are part of the scope.
- We can work nights or during closures so your doors stay open.
What pushes a business to add one
Every operator's numbers are different, but the same few motives come up in most first meetings.
Members keep asking
Recovery rooms are now a standard request at gyms and bouldering walls. A good sauna can be the reason a prospective member signs with you instead of the place down the street.
A hotel needs a reason to be booked
Small hotels near campus and around Fourth Street compete on amenities. A well-designed sauna, perhaps with a cold plunge next to it, gives guests a reason to choose you and gives you photos worth posting.
A studio is building around contrast sessions
Studios that sell sauna and cold classes need rooms sized to the class schedule, with fast recovery between groups and a heater that holds temperature while the door keeps opening.
An old room has worn out
Commercial saunas from the nineties tend to have cracked benches, undersized heaters and flaky controls. A renovation brings the room up to current code and trims the power bill along the way.
A co-op or apartment building wants a shared amenity
Housing co-ops and newer residential buildings are adding saunas to common areas. Those need fob access, auto shutoff timers and a care routine building staff can actually follow.
The sequence on a commercial job
Scoping meeting
We go over your floor plan, electrical service, ventilation and expected traffic, and list who signs off: landlord, architect, city and any health reviewer.
Drawings and approvals
We prepare or coordinate drawings for the City of Berkeley and the other reviewers. Tenant-improvement permits and owner approvals get tracked on a shared schedule so nothing sits for weeks in someone's inbox.
Construction
Framing, electrical, ventilation, waterproofing where needed, heater install and finish carpentry. We keep dust and noise contained and work around your hours.
Commissioning and staff training
We run the room through full cycles, log temperatures and airflow, and train staff on start-up, shutdown, cleaning and the daily checklist.
Specifications that hold up under heavy use
These details separate a commercial room that lasts from one that needs rebuilding in five years.
Heaters and controls
Commercial models from Harvia, Tylo and Saunum, with control panels mounted outside the hot room so staff can set hours and temperatures without going in. Steam rooms get commercial generators from Mr. Steam, ThermaSol, Steamist or Amerec.
Benches and backrests
Thick, clear bench boards in removable sections for cleaning, with eased edges and hidden fasteners. Where wear is heavy we use hardwoods or thermally modified stock.
Floor and wall construction
Slip-resistant floors that drain, sealed wall assemblies, and vapor control that protects the rest of the building. Steam rooms get full waterproofing and a sloped ceiling so condensation runs down the wall instead of dripping on customers.
Ventilation
Mechanical exhaust sized for the room and the head count, coordinated with the building HVAC so humidity stays out of the offices or apartments upstairs.
Lighting and sound
Heat-rated fixtures bright enough for cleaning crews and dimmable for use, plus speakers rated for heat and controlled from the front desk.
Salt walls and oil diffusers
Himalayan salt panels and aroma diffusers are popular in studios. We mount them with the heat and cleaning load in mind so the salt does not crack and the diffusers do not clog.
Commercial sauna budgets
Commercial saunas in Berkeley usually start around forty thousand dollars for a single mid-size room and can pass one hundred thousand for multi-room suites with steam and plunges. The big drivers:
- Room count, size and capacity.
- Electrical service upgrades and three-phase work.
- Mechanical ventilation and HVAC coordination.
- Accessibility and code-driven changes to the space.
- Heater and steam generator specs for continuous use.
- Night or phased work to keep the business open.
We give fixed bids after reviewing plans and walking the space. Once a room is open, we also offer scheduled service and fast sauna repair, so one failed element does not close your recovery area for a week.
Frequently Asked Questions
What codes apply to a commercial sauna?
The California Building, Electrical and Mechanical Codes, state accessibility rules, and Berkeley's local amendments. Facilities with pools or shared water may also fall under Alameda County Environmental Health. We sort out which apply before the drawings are finished.
How do traditional saunas compare to infrared rooms for a business?
Traditional rooms run hotter, suit longer group sessions and ride out constant door openings better once they are up to heat. Infrared rooms cost less to run and warm up quickly, which works well for booked private sessions. Plenty of studios offer both side by side.
Which brands provide eco-friendly sauna heaters and steam generators for commercial use?
Saunum and Harvia make efficient commercial heaters with controls that avoid heating an empty room. Tylo and Mr. Steam offer generators with auto-drain and scheduling features that save water and power. The largest savings still come from a tight building envelope and sensible hours.
How long does a commercial sauna project take?
Four to twelve weeks of construction is typical, plus permit time. Tenant-improvement reviews can add several weeks, so we start the paperwork early.
Do you service commercial rooms after they open?
Yes. Maintenance plans cover regular checks on heaters, stones, controls, benches and ventilation, and we move quickly when something fails during business hours.
