Scandinavian spruce

The base cladding wood for the wood-fired hot tubs, cold plunge tubs and saunas.

More than six colours for the hot tubs, more than four for the saunas.
Like any wood left outdoors, it changes over time: regular surface care helps preserve its appearance.

Colours and real-life appearance are confirmed in the quotation.

Three guidelines for deciding

If you want natural wood, plan for its surface care; otherwise look at thermowood or composite.
If the tub will be near the sea or heavily exposed, ask for 316 stainless steel for the stove.
For the tub shell, choose the colour that suits your garden: you see it with every bath.
