Sun Home Solaris 4 vs Solaris 6: which traditional outdoor sauna?
The Solaris saunas are handcrafted, hardwired traditional saunas. They share the same build, so the choice comes down to how many people you host, how big a pad you can build and what circuit you can run.

What actually differs
- Floor space: the Solaris 6 is about 21 inches longer, and both are about 7.9 feet tall. Sun Home lists about 6 inches of clearance on each side, so plan a pad bigger than the sauna.
- Heater and circuit: the 6 needs a dedicated 40A circuit, the 4 a dedicated 30A. Both are hardwired, so an electrician installs them, not a plug.
- Weight: both are heavy. The pad must be rated for the full weight, not just level.
- Price gap: about $9,000 at the current sale prices.
Before you order
- Delivery: the Solaris arrives fully built, so you need a level pad and a clear path to it.
- Lead time: they are handcrafted to order in Europe, about 3–4 months.
- Permits: some towns treat an outdoor sauna as an accessory structure. Check with your local building department.
Which one?
Choose the Solaris 4 if two to four people will use it and a 30A circuit is what you can run. Choose the Solaris 6 if you regularly host more than four and have both the pad and a 40A circuit. If you would rather not wait months or wire a dedicated circuit, an infrared model plugs into a 240V outlet and arrives in about half a day; see infrared vs traditional.
Health note. Sauna heat isn't right for everyone. If you're pregnant, have a heart condition or another health concern, talk to your doctor before you start.
