What Our Clients Say

We purchased a Sundance Chelsee hot tub in 2011 from Great Bay. Nothing but a positive experience with the team there during the purchase and follow up service. Great Bay sells high quality products and provides best in class service. I manage a customer service team for a large software company so I know the importance of both a great product and great people behind a product. At Great Bay you get both.
