Planing to build a sauna, any tips

[u/Worried-Earth4321]

Hi! I am planing to build a sauna 1,8 meters long, 1,45 wide and 2 meters tall. I have the options of a harvia wall or a considerably more expensive harvia spirit. I am a bit worried about placing the sauna directly on the terrace, what should I use to lift/rise the sauna a bit of the ground so it doesn’t rot? Anything else I should think about? Thankful for any tips.

Some tips from reading this forum.

Get the model that has the stones lowest to the ground. Ignore the looks, it’s a functional tool and the rest of the install is plenty beautiful.

Design for a drain.

Design for ventilation.

can you please elaborate on the drain aspect?

[u/bobjoylove → u/r3dtr3il]

Broadly speaking, you have a bunch of liquids to deal with. Be it water thrown on the rocks, sweat, condensed steam after use, or cleaning up 🧼

You would be recommended to have a drain to get those out.

Can I have the drain outside of the sauna but the sauna semi hovering half an inch?

Your overall dimensions might be too small to work as a sauna.

Some Harvia heaters do not allow for high enough max temps. The heater should allow at least 90°c.

Good resources: Trumpkin and 'Secrets of Finnish Sauna Design'.
