Sauna Construction in NoVA

Mayflower sauna projects start at $25,000 for an indoor pre-fab sauna, $36,000 for a custom indoor sauna, and $40,000 for an outdoor sauna. The final price depends on size, heater, glass, wood, the room or site, and any electrical upgrades. See the cost breakdown above for what each package includes.

A traditional sauna heats the air with an electric heater and stones, usually to high temperatures, and lets you add water to the stones for bursts of steam. An infrared sauna uses radiant panels that warm the body directly at lower air temperatures. Our standard packages use traditional stone heaters. If you are considering infrared, tell us during your consultation. Our traditional vs. infrared guide compares the two.

Yes. We build saunas in finished basements, spare rooms, bathrooms, closets, and other dry, finished spaces. An indoor pre-fab sauna needs at least 85 inches of ceiling height (about 90 inches is recommended). A custom indoor sauna is built inside an existing room, so the room and its walls must already exist, but we can fit almost any practical size or room shape.

Yes. A traditional electric sauna heater needs its own dedicated 240V circuit. The 4.5 kW heater in our indoor pre-fab package typically uses a 30 amp circuit, depending on the manufacturer’s specifications and your panel capacity. We confirm the breaker size, wire size, and circuit protection for your home, then pull the electrical permit and schedule the inspection.

Sauna electrical work requires an electrical permit and a final inspection. We obtain the permit, schedule the inspection, and cover the permit fees. An outdoor sauna can also involve zoning rules such as setbacks that depend on your county and lot, so we check the requirements for your address before we build.

A sauna heater is rated in kilowatts. The 4.5 kW heater in our indoor pre-fab package uses up to 4.5 kWh for each hour it runs at full power, and the 6 kW heater in our outdoor package uses up to 6 kWh. Once the sauna is hot, the heater cycles on and off to hold the temperature, so a typical session uses less than the maximum. Multiply the kilowatt-hours by your utility rate to estimate the cost of a session.

Choose indoor if you have a finished room to spare. It costs less to start ($25,000 for pre-fab, $36,000 for custom), and it is close to your shower and towels year-round. Choose outdoor if you would rather keep the space inside your home. Outdoor models start at $40,000, are designed for four-season use, and add panoramic glass views, but they need a prepared base.

Size by the number of people. Our indoor pre-fab cabins start at 4′×6′ for about 1 to 3 people and go up to 6′×8′ for about 6. Outdoor Pure Cube models start at 5′×5′ for about 1 to 2 people and go up to about 4. A custom indoor sauna starts at 5′×5′ for about 2 to 3 people, with custom dimensions, ceiling heights, and bench layouts to match your room.
