The 144"-192" 4-Piece Spa Cover is a large-format hard cover designed for oversized hot tubs or swim spas. Its segmented design makes it easier to handle and remove compared to single-piece covers of similar size. Built with a 1 lb foam core, it offers moderate insulation for typical outdoor conditions, and the 4" to 2" taper allows for proper water runoff and improved thermal retention. This cover is a great solution for homeowners looking to maintain energy efficiency, spa cleanliness, and safety for larger spa setups.
