Shoreline Spas SL1151L-18-148 Sterling Marble Spa with Gray Skirting, Pump, Pro Cover and in.Touch™ Tech - This spa is built for style, stress reduction, and therapeutic benefits. You won't have to play "musical chairs" to gain the utmost comfort from the generous number of therapy jets. These jets are all connected by the Shoreline Spas plumbing system, which provides maximum water flow through the use of extra large hoses and tubing. Sure-grip fittings ensure a secure bond between the pipes and jets. Diverter controls allow the user to adjust the amount of water pressure to each seat. This spa is compatible with the in.Touch™ mobile app and allows users to control all functions of the spa from iOS or Android smartphones or tablets.
