What a Home Sauna Really Costs

Updated October 2026. Prices change constantly; we quote only ranges that retailers publish, with links.

1. The sauna itself

Price depends mostly on type, size, and whether it is a prebuilt kit or a custom build. Published figures from sellers:

Takeaway: most prebuilt home units land in the low-to-mid thousands; custom builds can cost several times more. Get a written quote including freight.

2. Shipping and delivery

Saunas often ship by freight. Ask whether delivery is curbside or includes carrying it in, and whether there is a liftgate fee.

3. Electrical work

This is the cost buyers most often miss. Many traditional heaters and larger infrared units need a dedicated circuit (often 240V). An electrician's quote depends on distance from your panel and whether your panel has capacity. Check the model's spec sheet, then get a local quote before ordering.

4. Running cost

Estimate it yourself: heater kW × hours used × your electricity rate. Example: a 3 kW heater used 4 hours a week is 12 kWh. Look up your rate on your utility bill or the U.S. average on the EIA electricity price table. Actual draw is often lower than rated once the room is hot, because heaters cycle.

5. Site and extras

• Outdoor units: a level base (pad or pavers) and possibly a permit; check your local rules.
• Accessories: bucket and ladle (traditional), thermometer, towels, backrest.

A simple checklist before you buy

1. Pick type (see infrared vs traditional).
2. Measure your space, including door swing.
3. Read the spec sheet's electrical requirement.
4. Get an electrician quote.
5. Confirm freight terms, warranty, and return policy in writing.
