Steam Saunas
Tiled steam rooms and steam showers with the generator sized, plumbed and vented properly, so the room holds 110 degrees at full saturation without soaking the house.

Steam Rooms Built Wet-Tight
A steam sauna runs cooler than a Finnish room and far wetter: around 110 degrees at close to full saturation, which feels heavier and hits differently. That water has to be contained, which is why a steam room is as much a waterproofing job as a carpentry one. We build the enclosure with a full waterproof membrane behind the tile or stone, slope the ceiling so condensation runs to the walls instead of dripping on your head, size the generator against the room volume and the surface materials, and put the steam head where it will not scald a leg. Steam showers, where the same enclosure does double duty, are the most common version we build in bathrooms already being remodeled, and they pair naturally with an indoor sauna elsewhere in the house.
Why Our Steam Work Stays Dry Behind the Tile
Steam finds every gap. The failures we get called out to fix are almost always the same: a membrane that stopped at the wrong height, a ceiling with no slope, a generator sized for the floor area rather than the stone on the walls, or a drain line run without a way to flush it. We build the wet envelope first and pressure the details before any finish goes on, the same way we treat the vapor barrier in a traditional sauna.
- Full waterproof membrane, corners and transitions included.
- Sloped ceiling so condensate runs off rather than drips.
- Generator sized on volume and on how much stone or tile is in the room.
- Auto-drain and auto-flush generators specified as standard on our hard water.
- Steam head, controls and aroma dosing positioned for real use.
Reasons to Choose Steam
A steam room makes sense when:
Dry heat bothers you
Sinuses, skin and breathing all respond differently to wet heat. Plenty of clients who cannot get comfortable at 190 degrees dry are perfectly happy at 110 degrees wet.
The bathroom is being remodeled anyway
A steam shower is dramatically cheaper to build while walls are open and plumbing is exposed than it is to retrofit afterwards.
Space is tight
A steam shower occupies the footprint of the shower you already have. There is no separate room to find.
You want stone or tile rather than wood
Steam rooms let you build in tile, porcelain or stone, which suits some houses far better than a cedar-lined box.
Two people want different things
A steam shower in the bathroom and a traditional room outside covers both preferences without either being a compromise.

How We Work
From the first drawing to the first steam, one builder runs your project.
1. Volume, materials and generator sizing
We measure the enclosure, account for the thermal mass of the tile or stone and any glass, and size the generator from that. Undersizing here is the single most common mistake and it cannot be fixed with a longer run time.
2. Waterproofing and rough-in
Membrane, slope, drain, steam line and electrical rough-in, with the generator sited somewhere serviceable rather than sealed into a wall. We coordinate with your plumber or bring ours.
3. Finish, commissioning and handover
Tile or stone, door and glass, controls, steam head and aroma dosing. Then we run the room to full temperature, check saturation and hand over the descaling and flush routine.
Steam Room Details
The choices that come up on every steam build:
Generators
Sized in kilowatts against room volume and material. Auto-drain and auto-flush models cost more and last considerably longer on Central Coast water, which is hard enough to scale a basic unit quickly.
Steam showers vs dedicated rooms
A steam shower shares the enclosure with your daily shower and is the practical choice in most homes. A dedicated room can be larger, benched properly and finished as its own space.
Seating and slope
Benches in solid surface or tiled masonry, sloped to shed water, at a height that lets you sit for twenty minutes without your legs going numb. Ceiling slope is a minimum of two degrees.
Controls and extras
Digital controls with preheat scheduling, chromotherapy lighting, aroma dosing pumps and heat-rated speakers. Controls go outside the wet zone where they belong.
Ventilation and drying
An exhaust fan on a timer that runs after the session is what keeps a steam room from turning into a mold problem, and it is the first thing we check on a sauna repair call to a damp room. It is a small line item and it is not optional.
What Affects the Cost of Steam Saunas
Steam pricing tracks the wet work more than the finishes:
- Generator size and features. Output, auto-flush, and whether it drives aroma and lighting.
- Waterproofing scope. Membrane, slope, drain and how much of the surrounding room has to be rebuilt.
- Tile or stone selection. Material cost and labor, which on stone can exceed the generator.
- Plumbing and electrical. Water supply, drain routing and a dedicated circuit for the generator.
- Glass and door. A steam-rated enclosure with a proper seal and transom.
We quote the whole enclosure flat-rate, including the parts that get buried, rather than leaving waterproofing as an allowance. It is priced the same way as everything else in the full range of sauna work we take on.
Frequently Asked Questions
Which brands provide eco-friendly sauna heaters and steam generators?
We install across the major brands and can spec an efficient unit in any of them. On the electric heater side, look for a well-insulated cabinet, high stone mass and a modern control with scheduling, because holding heat efficiently matters far more than the nameplate rating. On steam, look for auto-drain and auto-flush generators: they use less water, scale far less on hard supply like ours, and last longer. We are not tied to one manufacturer, so the recommendation follows your room and your budget.
What is the difference between a steam sauna and a steam shower?
Mostly scope. A steam shower is your existing shower enclosure built to hold steam, with a generator, a sealed door and a sloped ceiling. A dedicated steam room is a separate space with proper benching and no daily shower duty. The waterproofing and generator sizing are the same discipline in both.
How much maintenance does a steam generator need?
On our water, plan on periodic descaling and a flush cycle after each session, which auto-flush models handle themselves. Elements are wear items and should be accessible without demolition, which is why generator placement matters as much as generator choice. We hand over a written routine and we service what we install.
Will a steam room cause mold in my bathroom?
Not if the envelope is right and the room can dry. That means a continuous membrane, a sloped ceiling, a properly sized exhaust fan on a run-on timer, and a door that seals during use and can be left open after. Failures we get called to almost always trace back to one of those four.
Can I have steam and a traditional sauna in the same house?
Regularly done, and it is a good combination: steam in the bathroom for weekday mornings, a traditional room outside for longer sessions. They use different equipment and different envelopes, so they are quoted separately, but a single design pass covers both.
