Thermal mats are insulating barriers placed between your hot tub’s base and the ground, preventing 25–30% of heat loss through ground contact. Without one, spas can lose significant warmth to cold concrete, decking, or soil, especially in winter.
Made from high-density, weather-resistant foam and sized to fit all Wave models, these mats not only improve energy efficiency but also offer puncture protection, added comfort, and structural support. In summer, they block ground moisture; in winter, they prevent freeze damage.
Installed before spa setup on a flat surface, they require only an annual check and mild cleaning. Paired with a thermal cover, they can reduce energy costs by as much as 60% for maximum efficiency.
