Mast3rPur™ Water Management System*

Only Master Spas has a blended system of three natural sanitizers for unparalleled water quality with clarity, silkiness and a fresh smell.

From the minute you sit down, you’ll feel the difference. Engineers use advanced technology to create seats that complement the contour of your body, making it easy to relax, naturally. Once you’re wrapped in comfort of the form-fitting seats, strategic jet placement delivers targeted hydrotherapy from head to toe.
