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: What is the floor made of on the Laatu outdoor sauna.

Question: Why do you sell the Laatu Roof Package without Shingles?
Answer: We offer both the Polar and Laatu Roof Packages with and without shingles. The reason we offer the roof package without shingles is to leave the shingle choice up to the buyer to decide at a later date. Some people prefer to try to match their sauna roof top to their existing homes roof top and use the same roof covering rather than the cedar shingles offered with the roof package which comes with shingles.

Question: Are the external controls for the Laatu Outdoor Sauna weather proof?
Answer: The digital D60 control is weather proof. The analog PSC sauna control will need to be protected somehow if mounted on outside of sauna, but because it has an electronic thermostat, you could have it wired into your house if you wanted.
