Before You Buy This Tub
You need a safe, level surface that supports the weight of 436 gallons plus people. The S6B arrives fully assembled, but you must ensure your deck or patio can hold this load.

You should also verify that your water source can fill the tub efficiently. The included insulated cover helps retain heat, but you may want additional wood storage nearby. This option suits those who want an off-grid experience without electricity. It differs from electric or gas models by requiring manual fuel management. Consider your willingness to tend the fire. If you prefer set-and-forget convenience, other spa types may fit better. The Thermo-Spruce construction requires occasional maintenance to preserve its weather resistance. Ensure you have space for the 89-inch diameter footprint.
