We'll see if we can make some modifications to sleep 4. Think removable Bunk beds. You could seat 4 indoors for meals or during inclement weather, convert to Sauna then sleeping quarters at night.

Upgrade your backyard today with a Dundalk cedar barrel sauna. Clear cedar benches on the inside can be used for a lying down or sitting up position. Automatic timer and temperature control built into the heater make operating this sauna a breeze.
