Wood-fired hot tubs are as simple as it gets.  No electricity needed, just an armload of firewood!  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 wood heater is very economical if you have a source of firewood and works well for this sized tub.  Tell me more about wood-fired heaters.
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.
