What We Do
Sauna builder services for home installation across Los Angeles
Los Angeles Sauna is a licensed builder that does the whole job: design, permits, framing, insulation, vapor barrier, ventilation, heater installation, finish carpentry and the first burn. We build traditional Finnish saunas with real löyly, infrared and hybrid rooms, steam saunas, barrel saunas, indoor conversions and outdoor cabins, and we install cedar tubs and cold plunges alongside them. When something stops working, including in rooms we did not build, we repair it. One project manager, one flat-rate quote, one crew from the first measurement to the day you use it.

Infrared Saunas
Full-spectrum and far-infrared cabins installed in Los Angeles homes, including builds that fit where a traditional hot room will not.
🪨
Traditional Saunas
Finnish-style hot rooms built for real löyly, with electric or wood-fired heaters, proper stone mass and ventilation that actually moves air.
💨

Steam rooms and steam shower conversions built with a properly sized generator, a fully waterproofed enclosure and drainage that will not fail in five years.
🛢️
Barrel Saunas
Cedar barrel saunas set on a proper pad with the electrical run, the flue and the deck handled, for backyards where a full cabin will not fit.
🏠

Home saunas built inside the house: basement rooms, master-bath conversions, closet builds and garage bays, framed and vented to hold heat properly.

Insulated cold plunges with chillers that hold 38 to 55 degrees year-round, built next to the sauna so the contrast circuit is a few steps rather than a drive.
🛠️
Sauna Kit Assembly
Assembly and installation of prefabricated sauna kits from any brand, including the rough-in, the electrical and the permit the instructions leave out.
Why Choose Los Angeles Sauna
We are a professional sauna builder rather than a general contractor who takes the occasional sauna job. That shows up in the parts of the build nobody sees: continuous foil vapor barrier, correctly placed intake and exhaust, heaters sized against the actual cubic volume and glass area of your room, and benches set to your ceiling height so the top bench sits in the hot layer where it belongs.
- Licensed, insured and permitted. California Class B general building license, insured and bonded, with every electrical and building permit pulled and inspected rather than skipped.
- One crew, one number. Design, permits, framing, electrical, carpentry and commissioning are all ours. Nothing gets handed off and nothing falls between trades.
- Flat-rate quotes. The number you approve after the design phase covers the heater, the wood, the wiring, the venting and the permits. No line items appear at the end.
- Every heat type. Traditional electric and wood-fired, infrared, hybrid and steam. We are not tied to one manufacturer or one system, so the recommendation follows your room.
- Materials that belong in a hot room. Clear cedar, hemlock, Nordic spruce, thermo-aspen and abachi. No chemically treated framing lumber anywhere the heat reaches.
- We come back. The same crew services what it builds, and we repair other people’s saunas too, which is the best education in what fails and why.

Our Mission
Bring authentic sauna culture to Los Angeles homes at the highest quality, bar none. Los Angeles got the wellness part of sauna long before it got the craft part, and the city is full of expensive rooms that never reach temperature, benches at the wrong height and cedar going black behind a missing vapor barrier. Our goal is simple enough to state and hard enough to do well: build rooms that work the way a Finnish sauna is supposed to work, in a climate and a housing stock that were not designed with them in mind. We would rather talk a client out of an oversized heater than sell one, and we would rather delay a start date than close up a wall we are not happy with.
Why Choosing the Right Sauna Builder Matters
Almost everything that decides whether a sauna is good gets covered up before you ever see it. That is what makes this a difficult thing to buy well, and it is why the cheapest quote is so often the most expensive one.
- Unpermitted electrical. A 60-amp heater circuit run without a permit is a fire risk, an insurance problem and a disclosure item at resale. It is also the single most common corner cut on low bids.
- A missing or punctured vapor barrier. Skip it, or stop it short at the ceiling, and moisture moves into your framing. You find out two or three years later when the wood goes dark and soft, and by then the fix is a rebuild.
- Ventilation treated as optional. Without intake below the heater and exhaust on the far wall the air goes stale, the room smells within a year and the floor stays cold while the top bench cooks.
- A heater sized off a chart. Glass doors, uninsulated walls and high ceilings all add load. A heater picked on square footage alone gives you a room that never quite gets there.
- Bench height guessed at. Heat stratifies. Benches set without reference to the ceiling put your head in the cool layer, and no heater size fixes it afterwards.
- Treated lumber and sealed wood. Chemically treated framing and varnished interiors both off-gas at 190 degrees. Neither belongs anywhere near a hot room, and both turn up in DIY builds regularly.
Talk it through with a licensed builder before you commit to anything. Call: (818) 873-4902
What Affects the Cost of Sauna Installation
Sauna installation pricing in Los Angeles moves with the size of the room, the heater and how much of the space has to be rebuilt. The main drivers:
- Room size. A 4×5 two-person room is the entry point. A 6×7 four-person room is the most common build. Family-size and outdoor rooms scale from there.
- Heater type and output. A 6kW electric heater is the value option. Wood-fired stoves add a flue and a combustion permit. Air-circulation and humidity-control heaters sit at the top of the range.
- Electrical distance. A short run from a nearby subpanel is a modest line item. A long run through finished walls, or a panel upgrade, is not.
- Wood species. Western red cedar is the benchmark. Hemlock and Nordic spruce come in slightly under it. Thermo-aspen and abachi are the premium tier.
- How much rebuilding is needed. A framed, insulated space ready to receive paneling installs fast. A garage bay with no insulation and no vapor barrier does not.
- Permits and inspection. Electrical permits are standard on every install. Framing changes and outdoor structures add a building permit. Both are quoted up front, never added later.

We quote installation flat-rate after the site visit. Heater, wiring, venting, permit and first heat-up are all in that number.

Frequently Asked Questions
How much does a home sauna installation cost?
In Los Angeles most home sauna installations land in a wide band depending on room size, heater and how much of the space has to be rebuilt. A small two-person indoor conversion in an already framed closet is the low end. A six-person cedar room with a premium heater, new circuit and glass door is mid-range. Outdoor cabins with a foundation, roof and buried electrical run are the top end. We quote flat-rate after a site visit, with the heater, wiring, venting and permit included.
What are the electrical requirements for a sauna heater?
Nearly every electric sauna heater needs a dedicated 240V circuit with no other loads on it. A 4.5kW heater typically needs 30 amps, a 6kW heater 30 to 40 amps, a 8 to 9kW heater 40 to 50 amps and a 10.5 to 12kW heater 60 amps. The wire has to be sized for the run length and the heater has to be hard-wired, not plugged in. We check your panel capacity first, because older Los Angeles homes on a 100-amp service often need a subpanel or a service upgrade before a large heater is viable.
Can I install a sauna without a permit?
Not legally in Los Angeles, and not safely. The dedicated 240V circuit requires an electrical permit in every jurisdiction we work in. Framing a new room or building an outdoor structure adds a building permit, and a wood-fired heater adds a combustion and venting permit. Unpermitted work turns into a problem at resale, during an insurance claim, or on the day something fails. We pull every permit as part of the install and coordinate the inspections.
How long does a sauna installation take?
An indoor conversion in a space that is already framed usually runs one to two weeks on site once materials arrive, plus permit lead time. A full closet or garage conversion runs two to three weeks. Outdoor builds with a foundation take four to six weeks. The heater and wood order is normally the longest lead item, so we place it as soon as the spec is signed.
Which brands provide eco-friendly sauna heaters and steam generators?
We install across the major brands and can spec efficient units in any of them. On the electric side, look for heaters with well-insulated cabinets, high stone mass and a modern digital control with a scheduling timer, because holding heat efficiently matters far more than the nameplate rating. On the steam side, look for auto-drain and auto-flush generators, which use less water and last considerably longer in hard-water areas like ours. We are not tied to one manufacturer, so we will spec whatever fits your room and budget.
