Design-Your-Own Ultra Deluxe Spa & Hot Tub Covers: 6/4 Taper with 1.0# Foam Base Cover with R-23.85
Product Review (submitted on October 10, 2012):
Great cover, great communication, great service! This cover is far superior to the stock cover that came with our Hot Springs spa. It insulates much better with less weight. The quality and appearance of the cover are perfect. Thanks!
