The high-end Cubo XL 3-Room Sauna is crafted using a unique process known as Thermal Modification. This treatment heats the wood to over 400 degrees, effectively destroying all organic compounds. The high temperature gives the wood a beautiful rich, deep brown tropical appearance, ideal for blending into your garden setting. Thermally Modified Wood is also water-resistant, weather-proof, insect-repellent, and will not chip, warp, expand, or contract.

It takes only 60-90 minutes to heat up, giving you a luxurious personal spa experience in the privacy of your home. With three generously sized rooms totaling 115 Sq. Ft. of space and accommodating up to 6 people, it is ideal for creating memorable moments of relaxation with friends and family.  

Adding a touch of style to your outdoors, the exterior features floor-to-ceiling doors, matching floor-to-ceiling windows, and a large round viewing window, all fitted with stylish bronze-tinted tempered glass.
