Reviews
What customers say
Customers describe the staff as knowledgeable and helpful, with clear guidance on pool chemistry. One spa buyer appreciated an after-hours chance to try a lounge seat and received start-up guidance. Another hot-tub buyer says a delivery worker noticed a bad lid and said a replacement would be ordered, but the buyer was still waiting for service to respond three weeks later.
