Question: What are the differences between "pre-built", "pre-cut", "outdoor" and "portable" traditional saunas?
Answer:

Pre-Built (Modular) Saunas come in modular insulated panels that are assembled together to form a fully functional room.

Pre-Cut Sauna Kits require that you frame up your own walls and provide your own insulation. Tongue and Groove boards from the kit are provided to attached to the inside framing of your room.

Outdoor Traditional Saunas are exactly like a pre-built's in addition to having a roof package option.

Portable Traditional Saunas are small modular rooms that are capable of plugging into standard wall outlets (15amp or 20amp).

Question: Can pre-built sauna kits ever be dis-assembled and moved?
Answer: Yes, they can be assembled and re-assembled somewhere else. It is a 2-4 hour project to assemble and/or dis-assemble.

Question: Why would somebody want to purchase a Pre-built Sauna?
Answer: A pre-built sauna is a modular, self-standing sauna which can be installed into an area of an existing room/garage or even outdoors (additional roof package required). The pre-built sauna comes all ready made – the walls arrive to you in pre-insulated panels, which would then be placed into their designated location for the kit to create a self-standing sauna room.

Question: Does a "pre-built" come fully assembled? How will I get it upstairs?
Answer: Pre-Builts are modular sauna units that arrive in separate panels. These panels are packaged in a manner that makes it easy to move to the location of set up (i.e. through a standard door or hallway).
