The Cornwall hosts deep corner seating with two higher middle seats to offer multilevel seating for your friends and family to enjoy. The 18 adjustable hydrotherapy jets and air control valves allow everyone their own personal massage! Canadian Spa Company spas use Glacier filtration with silver ion technology and a built-in Ozone generator to keep your water crystal clear without hassle- letting you focus on enjoying your time in the spa, rather than caring for it! Plug the spa directly into a standard 15A household outlet – no electrician required!
