Generally, NO you do NOT need to remove drywall when installing a sauna build
However, it’s important to mention you still ABSOLUTELY MUST …
- Add insulation batting between studs in the walls — formaldehyde-free is best
- Affix sauna foil vapor barrier over the drywall
- Then, mark your studs so you know their location to affix T&G cedar paneling to the walls
- Use longer nails to reach studs when attaching your cedar paneling to the walls and ceiling
All said, of course you must still wire for the sauna heater, lights and switch and add intake and exhaust vents per your design
We offer generic sauna plans on all of our sauna product pages. Just pick your sauna type (Modular PreFab Kit or Materials Package) and then choose a size, e.g. 4×6, 5×7, etc. You’ll see plans you can design on Step 1.
So sometimes, it makes more sense to remove all drywall to accomplish the list of tasks above. And when removed, you have about 1 more inch of space. Not a big deal in larger saunas, still it may be helpful when installing a bench to have that extra inch.
