Dimension One Spas

Dimension One Spas (D1) has been the leader in the design and manufacture of premium hot tubs since 1977. What other companies consider innovation is old news for D1, who was the first to utilize ozone, introduce fountains and patent the curvilinear shape of the Bay Collection — not to mention over 30 other patents. The design and engineering team at D1 have taken the time to listen to YOU, which has led us to develop the most therapeutic and relaxing experience available. The seats in our spas are based on over 100 measurements of the human body so you can always find the perfect fit.

D1 is also committed to the quality of your tub for life. That’s why our patented UltraLife™ shell carries a lifetime warranty against cracks, leaks, fading or other wear from environmental exposure. Our patented Envirotect skirting, built from durable, all-weather material including recycled milk jugs, also carries a lifetime warranty. It requires no waterproofing or staining and will look as new as the day you bought it for years to come.
