What the price includes
The price usually covers the sauna, the heater, benches, and basic assembly. Bob Vila lists labor at $700 to $3,000. Wiring, a new circuit, plumbing, a floor, and a base for outdoor saunas often cost extra. Running costs are small. Home and Heat lists $10 to $30 a month for power. Ask what is in the quote. It does not include tax or extras the provider adds on the day.
Who charges this and how it is billed
Sauna work is done by sauna dealers, general contractors, handymen, and electricians. Dealers often sell the sauna and install it for one price. Others bill labor by the job or by the hour. Bob Vila lists plumbing at $45 to $200 an hour. An electrician often bills wiring on its own, at $250 to $900 on HomeGuide. Ask for one written quote that shows the sauna, labor, and wiring apart.
When you need this
Hire a pro if you want a built in sauna, an outdoor unit, or any heater that needs new wiring or a new circuit. A kit can be put together by a handy owner, but power and safety work should go to a licensed electrician. Check your local rules and ask if you need a permit before work starts.
How to judge your quote
- Does the quote include the heater, benches, wiring, and a new circuit?
- Is the price for a kit, a prebuilt unit, or a custom build?
- Who handles permits, and does an electrician do the wiring?
- Is there a warranty on the heater and the work?
- Compare the total with the range above: $2,500 to $10,000 per installation for most people in 2026.
Ways to pay less
- Pick an infrared sauna. Bob Vila lists $1,500 to $6,900, and HomeGuide notes that most infrared units run on a standard 110 volt outlet.
- Buy a prefab kit and assemble it yourself if you can. Bob Vila lists $300 to $1,500 for paid kit assembly.
- Place it where wiring is close. HomeGuide lists $250 to $900 for a dedicated circuit, and a short run costs less.
- Compare at least three quotes. Home and Heat lists installation at $500 to $2,000, so quotes vary a lot by job.
- Start small. Home and Heat lists quality 2 to 3 person units around $2,000 to $3,500, below bigger custom builds.
