Thickest Hot Tub Covers: 6"-4" Tapered with 1.0# (R23.85-R37) $488.88
Product Review (submitted on June 24, 2015):
Outstanding customer service, kept me apprised of the status, shipping service was excellent and I was able to arrange a time that I was available to have it delivered. The cover is superior. The cover that came with the hot tub was flat and about 2" thinner; this cover definitely keeps the cold air out and the tapered design allows snow and rain to roll off. Highly recommend this company. Order ##110981
