Hand Made Wood Fired Hot Tubs

Thermowood Wood Fired Hot tub

Heat treated ThermoWood is a class 2 type of wood & is in the same category as cedar and oak.

It is an extremely durable timber & has a rich dark colour resembling a more “exotic” species of wood. During the heat treating process the wood is “aged” so that it takes on the structure of a more refined wood type whilst still remaining comparatively light in weight.

All of our tubs include, Internal seats, external steps, wooden cover with handles, heater fence, wooden paddle for water mix, decorative top rim, drinksholder and ash shovel.
