About Oakland Custom Saunas
Real heat, real wood, and a room that lasts
Oakland Sauna designs and builds hot rooms, cedar tubs and cold plunges across Oakland and the East Bay. We are a licensed and insured California contractor, and the same crew that measures your space frames it, seals it, wires it and hands it over. There is no subcontractor chain to point fingers down when something is wrong.
We work in western red cedar, hemlock, thermo-aspen, alder and Nordic spruce, with electric, wood-fired, hybrid and infrared heat. Some clients want traditional saunas with stones and real steam. Others want infrared saunas, which run on a modest circuit and are warm in fifteen minutes. Both are good answers, and which one is right for you usually comes down to your space and your electrical panel rather than taste.
Oakland housing makes this specific work. Craftsman bungalows and Victorians in the flatlands often still carry 60 or 100-amp service with original wiring in the walls, so we open the panel before we quote a heater. Basements below grade take on moisture in a wet winter, which means the vapor barrier has to be a continuous system rather than an afterthought. Up in Montclair and the Upper Rockridge, hillside lots sit inside a Very High Fire Hazard Severity Zone, which decides whether a wood-fired stove is even on the table. We check all of that before you spend anything.
Most people come to us with a space rather than a plan. A closet, a garage bay, a basement corner, a flat patch of yard. We turn it into a room that reaches 180 to 200 degrees in half an hour and holds it without punishing the power bill. That single number, how long it takes to get hot, decides whether a sauna gets used four nights a week or twice and then fills up with bicycles.

Why Choose Us
We are a licensed and insured sauna builder and we do the whole job in house, from the first measurement to the first heat cycle. Our crew are finish carpenters who specialise in heat, which is a rarer combination than it sounds. Plenty of contractors can frame a box and plenty of sauna companies can drop in a kit, and the seam between those two skills is where most disappointing saunas come from. We build every kind of room, from compact indoor saunas in a basement to full outdoor saunas on a hillside lot, and we price the job fixed after seeing it rather than by the hour.
- The same people who design your room are on site while it gets built.
- We open your panel before quoting a heater, because capacity decides what is possible.
- We pull Oakland Planning and Building permits and meet the inspector ourselves.
- We give you a written spec naming the heater, the wood, the venting and the electrical.
- We build for East Bay conditions, where a damp flatland basement and a dry hillside sit two miles apart.
- We answer the phone years later, and we service what we build.
Our Mission
Our goal is straightforward. We want to build rooms so well made and so easy to use that they become part of how you live, not a project you finished once. Every room should hold up for decades, heat evenly every single time, and be somewhere you actually go on a wet Tuesday in February. A sauna that sits cold eleven months a year was built wrong, whatever it cost. That is why we spend so much of the first visit on heat-up time, bench height and where the door swings, because those are the things that decide whether a room gets used.
Why It Matters
A sauna puts high heat, water and 240 volts inside one small sealed room, so a bad build is more than a letdown. Wiring done wrong trips breakers at best and starts fires at worst. Poor sealing and weak ventilation lead to mold and rot behind the paneling, which nobody sees until it reaches the framing and the repair bill is in five figures. A heater sized off a chart instead of the room never makes proper steam, so the room gets abandoned. And an unpermitted build tends to surface during a sale, when it stops being a feature and becomes something a buyer wants priced down or torn out. Hiring a licensed, insured builder who gets it right the first time protects your house, your money and your warranty, whether the job is a new build or a sauna repair on something you already own.
What Affects the Cost
Every quote we write is fixed price after a site visit, never a range over the phone. These are the things that move the number most:
- Room volume, because it sets heater output and paneling quantity at the same time.
- Wood species and grade, where clear vertical-grain cedar can be three times hemlock for the same room.
- Electrical capacity, and whether your panel carries the heater as it stands or needs upgrading first.
- Indoor against outdoor, since outdoor adds a pad, drainage and a trenched circuit but avoids sealing the house.
- Heat source, with wood-fired adding a flue, clearances and a fire zone review in the hills.
- Glass area, because a full-glass front looks superb and needs a bigger heater to hold temperature.
- Access, since carrying material down a hillside side yard with no vehicle access is real labour.
If a smaller or simpler build would get you most of what you want, we will say so. Barrel saunas are often the cheapest honest route to real steam in an East Bay yard, and a cedar tub install sometimes suits a small garden better than a hot room would.

What East Bay Homeowners Say
Frequently Asked Questions
How much does a home sauna installation cost?
Most Oakland home installs land between eight and twenty-two thousand dollars complete, covering the heater, the wiring, the permits and the finish work. Small indoor conversions sit at the low end and large outdoor cabins with a pad and a trenched circuit sit above it. Wood grade moves the number more than square footage does. We quote fixed price after seeing the space.
Is a sauna in your house worth it?
For people who use it, yes, and the honest test is whether using it is easy. A well-insulated room that is at temperature in half an hour gets used several times a week. A room that takes ninety minutes gets used twice and becomes storage. That difference is decided during the build, in the insulation, the sealing and the heater sizing.
Do saunas increase property value?
A permitted, well-built sauna generally reads as a finished feature and helps, particularly in an East Bay market where buyers actively look for wellness features. An unpermitted one usually does the opposite, because it turns up during inspection and becomes a negotiation item. The permit is what separates the two outcomes, which is why we pull them as part of the job.
Can I have a sauna in my backyard?
In most Oakland yards, yes. What governs it is setbacks from your property lines, lot coverage, and whether you sit in a fire severity zone or a special district. Small structures on cradles are the easiest path and often avoid a building permit, though the electrical still needs one. We check your specific parcel before you spend anything.
What are the electrical requirements for a sauna heater?
A typical 6 to 8kW electric heater needs a dedicated 240V circuit at 30 to 40 amps on its own breaker with nothing else on it. Larger rooms go to 60 amps. Infrared cabins are far lighter and often run on 120V. Because a great many Oakland homes still have 60 or 100-amp service, we check panel capacity before recommending any heater.
What are the benefits of hiring a professional sauna builder?
Three things that are expensive to buy back later. Correct sealing and ventilation, which decides whether the wall assembly rots. Correct heater sizing, which decides whether you use the room. And a permit history, which decides whether the room helps or hurts you at resale. A professional build also carries insurance, which matters when there is 240V and water in one small sealed room.
