This guide covers safety-relevant topics and is awaiting final editorial safety review. Always follow the manufacturer's manual and consult licensed professionals.
1. Start with the site, not the sauna
Measure the level area you can realistically dedicate, then add room for door swing, maintenance access and a path. Note how a delivery pallet will reach the spot — gates, steps and slopes matter.
- Usable level footprint (width × depth)
- Narrowest point on the delivery route
- Distance to your electrical panel
- Drainage and sun/shade
2. Choose the heat experience
Traditional saunas heat air and stones; you can pour water for steam (löyly). Infrared saunas warm the body with emitters at lower air temperatures. Wood-fired heaters offer an off-grid traditional experience but add chimney and fire-safety requirements.
3. Understand the electrical reality
Most outdoor traditional heaters need a dedicated 240V circuit installed by a licensed electrician. A standard outdoor outlet is not a substitute. Model-specific requirements must come from the manufacturer's installation manual.
4. Read capacity carefully
Advertised person counts describe how many people can technically sit, not how many are comfortable. Compare bench lengths and interior height where the manufacturer documents them.
5. Budget for the whole project
The sauna is only one line item. Foundation, electrical work, trenching, delivery, assembly and permits can add substantially. Our installation cost calculator lets you model every assumption.
6. Check local rules
Permit, setback and accessory-structure rules vary by city and county. Call your local building department before ordering — no single rule applies across the US.
Frequently asked questions
What size sauna do I need?
Plan around regular users, not occasional guests, and compare documented bench lengths. Use our size and bench tools to distinguish advertised capacity from documented seating geometry.
Do I need an electrician?
For hardwired electric heaters, yes — hire a licensed electrician and follow the exact manufacturer manual.
