What We Do
What a Newport Beach sauna builder actually does
Newport Beach Sauna takes a hot room from first sketch to first heat cycle without handing any of it off: design, permits, framing, insulation, vapor barrier, ventilation, heater, finish carpentry and commissioning. We build traditional Finnish rooms with real löyly, infrared and hybrid cabins, steam saunas and steam showers, barrel saunas, indoor conversions and outdoor cabins, and we install cedar tubs and cold plunges alongside them. Building within a mile of the water changes the specification more than most people expect, and we spec for it: marine-grade fasteners, stainless bands, corrosion-rated heater housings and a vapor barrier detail that assumes the marine layer is going to test it every single night. When something stops working, in a room we built or one we did not, we repair it. A single project manager, a single fixed price and a single crew, from the first tape measure to the day you sit in it.

Why Choose Newport Beach Sauna
Saunas are what we build, rather than something we take on between other work. The difference is entirely in what disappears behind the paneling: a foil vapor barrier run continuous and taped at every lap, intake and exhaust sited where air will genuinely move between them, a heater sized against the room's real cubic volume and glass area, and benches set off your ceiling height so the top one sits up in the heat instead of below it.
- Licensed, insured, permitted. We hold a California Class B general building license, carry insurance and bonding, and take out every electrical and building permit the job needs. Inspections happen before walls close, not after.
- Built for the coast. Salt air eats hardware. We specify stainless and marine-grade fasteners, corrosion-rated heater housings and sealed exterior penetrations as standard, not as an upgrade line item.
- One crew, one number. Drawing, approvals, framing, wiring, carpentry and commissioning all sit with us. Nothing gets handed between trades and nothing falls through the gap.
- One price, fixed. What you sign after the design stage includes heater, timber, wiring, venting and permits. The final invoice matches it.
- All of the heat types. Traditional electric and wood-fired, infrared, hybrid and steam. No exclusive dealerships, so what we recommend follows the room rather than what is sitting in a warehouse.
- Wood chosen for heat. Clear western red cedar, hemlock, Nordic spruce, thermo-aspen and abachi, with nothing chemically treated anywhere the heat can reach it.
- We service what we build. The crew that put the room in is the crew that comes back to it, and we repair other people’s rooms as well, which teaches you more about failure modes than building alone ever does.

Our Mission
Build the best saunas in Orange County, and build them so a room installed today is still worth using in twenty years. Newport Beach took to the wellness side of sauna early and there are a lot of expensive rooms along this coast that never quite reach temperature, benches set at the wrong height, and cedar going black behind a vapor barrier that stopped six inches short of the ceiling. We would rather talk a client down to a smaller heater than sell a bigger one, and we would rather push a start date than close a wall we are not happy with. Every homeowner who calls gets a straight answer about what their space can and cannot support, whether or not that answer ends in a sale.
Picking a Builder Is Most of the Decision
By the time a sauna looks finished, every decision that determines whether it is any good has disappeared behind cedar. That is what makes one hard to buy well: you cannot inspect the part that matters. It is also why the lowest number on the table has a habit of turning into the most expensive room on the street about four winters later.
- Wiring done without a permit. A 60-amp heater feed pulled off the books is a fire risk, an insurance exposure and something you have to disclose when you sell. It is also the first thing a cheap bid leaves out.
- A vapor barrier that stops short. Skip it, puncture it, or run it to within a foot of the ceiling and moisture moves straight into your framing. In this climate you find out in two or three winters, and by then the repair is a rebuild.
- Venting left as an afterthought. No intake under the heater and no exhaust opposite it and the air goes flat, the room smells within a year, and you sit with a cooking head and cold feet.
- Hardware that was never rated for salt air. Zinc screws, mild-steel bands and an unsealed flue penetration will look fine on handover day and be weeping rust by the second summer on any lot within a mile of the sand.
- A heater sized off a chart. A glass door, an uninsulated outside wall and a tall ceiling each add to what the heater has to overcome. Pick the heater on square footage alone and you get a room that never quite arrives.
- Bench heights guessed. Heat stratifies sharply. A bench positioned without reference to the ceiling leaves your head in the cool air, and there is no heater you can buy afterwards that corrects it.
- Treated lumber and sealed finishes. Pressure-treated framing and varnished linings both give off fumes once the room is at temperature. Neither belongs near a hot room, and both turn up in DIY builds constantly.

What Affects the Cost of Sauna Installation
Three things set an installation price: how big the room is, which heater goes in it, and how much of the existing space has to come apart first. In detail:
- Room size. Four feet by five, seating two, is where this starts. A 6×7 four-person room is our most common build. Family-size and outdoor rooms scale up from there.
- Heater type and output. A 6kW electric sauna heater is the value option. A wood stove brings a flue and a combustion approval with it. Heaters with air circulation and humidity control occupy the upper end.
- Panel condition and cable distance. A short pull to a nearby subpanel barely registers. Fishing a long run through finished walls, or upgrading a 100-amp service first, certainly does.
- Species. Western red cedar is the reference point. Hemlock sits just under it. Thermo-aspen and abachi are the premium choice, worth it for benches you can sit on at full temperature.
- Demolition and rebuild. A space already framed, insulated and ready for paneling moves quickly. A garage bay with open studs, no insulation and no vapor barrier is most of a week before any cedar appears.
- Permits, and coastal review. An electrical permit applies every time. Framing changes and garden structures add a building permit, and a lot inside the coastal zone can add a CDP. All of it quoted at the start.

Installation is quoted flat-rate after the site visit. Heater, wiring, venting, permits and the first heat-up are inside that number, and the same basis applies to Commercial Saunas once the drawings are settled.

Frequently Asked Questions
How much does a home sauna installation cost?
Room size, heater class and how much building has to happen before the sauna goes in set the number. The lowest projects are two-person rooms dropped into a closet that is already framed and already has a spare circuit. Mid-range is a six-person cedar room with a good heater, a new 240V circuit and a glass door. The top is an outdoor cabin on footings with a roof and a trenched feed. After a site visit you get one flat price covering heater, wiring, venting and permits.
What are the electrical requirements for a sauna heater?
A dedicated 240V circuit, hard-wired, with nothing else sharing it. Rough sizing runs 30 amps for a 4.5kW heater, 30 to 40 for 6kW, 40 to 50 for 8 to 9kW, and 60 for 10.5 to 12kW, with conductor size then set by the length of the run. The first thing we look at is the panel, because much of the older stock on Balboa Peninsula and in Corona del Mar is still on a 100-amp service, and a large heater there means a subpanel or a service upgrade first.
Can I install a sauna without a permit?
No. The 240V circuit on its own requires an electrical permit in every Orange County jurisdiction we work in. Framing a new room or erecting an outdoor structure brings in a building permit, a wood-fired heater brings in combustion and venting review, and a parcel inside the coastal zone can also require a Coastal Development Permit. Skipping the paperwork surfaces later, at resale, in an insurance claim, or the day something goes wrong. Permits and inspections are inside our quoted price.
How long does a sauna installation take?
Count from the day the last carton lands, not from the day you sign. Taking a closet or a garage bay back to the studs and rebuilding puts it at two to three weeks. An outdoor cabin with footings and a roof is four to six. The critical path is almost always the heater and wood order, so we release it the day the specification is signed instead of waiting for plan check to clear.
Which brands provide eco-friendly sauna heaters and steam generators?
Efficiency comes from the room and the control far more than from the badge on the heater. In an electric heater we look for a well-insulated cabinet, plenty of stone mass to hold heat, and a control that can be scheduled so the room is not drawing power while it waits for you. In a steam generator, auto-drain and auto-flush are the features worth paying for on Orange County water, which is hard enough to scale a generator early. We carry no exclusive lines, so the spec follows your room.
