Why Earth Spas?

Energy efficiency means wellbeing for our planet

Earth Spas builds hot tubs that are not only good for you, but also for our planet. Through high-quality insulation, intelligent control and well-engineered technology, our hot tubs keep energy where it belongs: in the water. That lowers running costs and conserves natural resources.

Rapid Foam Technology

Rapid Foam Technology

Rapid Foam Technology wraps every Earth Spas hot tub in a dense, insulating foam layer. Heat stays in the water, energy consumption drops — and your hot tub reaches the desired temperature faster.

Reflective insulation layer

Reflective thermal insulation layer

An additional reflective layer reflects heat radiation back inward and prevents heat loss. Even on cold days your hot tub stays efficiently warm — without unnecessary energy use.

Seamless foam-core connections

Seamless foam-core connections

Seamless connections between the foam cores close every potential thermal bridge. The result: consistently low energy consumption and a hot tub that stays reliably efficient even in winter.
