We are pleased to introduce a brand new way to get more from your hydrotherapy experience. Our variable speed pump system allows you to select your desired level of massage strength. With the touch of a button you can increase (or decrease) your massage intensity at any time. Press the “Wave” button to activate an automatic massage setting where the hydrotherapy jet power slowly varies allowing you to sit back and relax as your muscles are relieved from built up stress and tension.Since you are in control, you will be guaranteed to get exactly what you want from your variable speed massage therapy seat. Ask for this option to be installed on your Coast Spas hot tub.
