Patented Adjustable Jets
Varying the power of your massage is easy with patented jets featuring an adjustable design that makes it easy to grip and turn underwater.

Ultra Pure Water Management System
D1 uses low power, 98 Watt circulation pumps to purify your water. In fact, 84% of the power that Ultrapure uses is returned to the water as heat, warming your hot tub for free.

Echo Switch
Various-sized therapeutic “bumps” have been grouped together at key acupressure points for the arms, hands, wrists, and feet. These bumps stimulate trigger points in these areas, providing you with an acupressure massage

High-Density Foam Covers
Every D1 hot tub has a custom cover that has been tailored specifically to fit the hot tub model it is delivered on. In addition to a tight fit on the edges, every cover has a linear heat seal on the seam to prevent heat loss.
