A Coast Spas® hot tub delivers a world of new experiences, improved health and an environment that is meant to be shared with friends and family. We've been an innovator in the Hot Tub industry since our inception in 1996. Coast Spas was the first to install modern lighting, audio and video systems and commercial-grade Hydro Cyclonic filtration systems into the portable hot tub. Coast Spas also holds several patents such as our Infinity Edge design for both hot tubs and swim spas. Coast Spas is one of the few hot tub manufactures to be ISO 9001:2015 quality certified.
