Product Description

This is a small, one or two person cedar hot tub that comes in a choice of two shapes - round or elliptical.  The small size uses less water and energy than larger tubs.  The gas heating system keeps your tub ready to use any time.  Gas heaters are a good choice for very cold climates or large tubs.  Includes freeze protection for winter use.
All our hot tubs are made with Western Red Cedar, a beautiful and sweet smelling material that is perfect for hot tubs. We use only premium grade wood(clear - all heartwood). Other woods available on a custom basis. Tub design features our unique industry-leading curved sides and rust-free stainless steel banding. Maintenance on our wood tubs is straight-forward and simple.  Add the optional UV water purifier for a chemical-free approach to safe clean water.
