Outdoor Sauna Kits: What You Get and What You Still Need
By Caleb Whitaker Prices checked
An outdoor sauna kit is a pre-cut sauna you assemble yourself, usually in a day with two people. Kits we checked on November 11, 2026 cost $4,485 to $9,860. The big difference between kits is whether the heater is included.

The kit checklist
Before comparing two prices, tick off each of these for both kits:
- Heater and controls. Adds $1,195 to $3,800 if missing.
- Sauna stones.
- Roof cover or shingles. Bare staves on top will weather fast.
- Floor or duckboard. The SaunaLife E7 floor was a $245 add-on.
- Base cradles to keep the wood off the ground.
- Lighting.
- Freight to your address.
How hard is assembly?
Kits are designed for two adults with basic tools. Barrels go up stave by stave on cradles, then the bands are tightened. The heater is the part you should not do yourself: a 240V heater must be wired by a licensed electrician.
Kit or custom build?
A kit trades flexibility for certainty. You know the price and the parts on day one. A custom build lets you fit an odd space and add insulation, but labor and materials are harder to predict.

Assembly day plan
- Have the base level and the electrician booked before delivery.
- Check every part against the packing list before you start.
- Set the cradles or floor frame and check level both ways.
- Build the walls or staves, then the roof and door.
- Fit benches, then the heater mount. The electrician connects the heater.
- Run an empty first session per the heater manual.
