Over 20 Years of Spa Cover Experience
Are you buying from someone that knows spa covers or someone telling you what you want to hear? We know about covers because we have marketed and sold them for a long time.

Tapered Foam Cores for Rainwater Run-off more info
We offer a variety of densities and tapers to give you more of a selection of price to functionality. Our spa covers are tapered so the rainwater runs off your cover instead puddling on it. We highly recommend our Thermal Guardian models because they feature 2 " of fall instead of only 1" found on offerings from other retailers.

UV-Resistant SpaLux Premium Spa Cover Vinyl more info
Our SpaLux vinyl has been specially formulated for the rigors that outdoor spa covers face. Exceeds the specifications of premium marine-grade vinyl.

Exceeds the ASTM F1346-91 specification for manual safety spa covers more info
Thermal Guardian spa covers exceed the specification for center-deflection perimeter rescue and the safety labeling requirements of ASTM F1346-91. Some jurisdictions are requiring that spa covers be manufactured in accordance with these guidelines.

Premium Materials = Premium Spa Cover
A spa cover is the sum of its parts. If you use good materials in the manufacture of a spa cover, you will get a good spa cover. In over 20 years of spa cover manufacturing, our manufacturer has found the finest materials available to build our covers. From the UV-treated thread to the industrial zippers and the premium SpaLux vinyl to the virgin EPS foam, Thermal Guardian premium spa covers are manufactured to the highest quality standard.

Superior Vacuum-Heat-Seal Technology more info
A cover's ability to repel water saturation of its foam cores is a fundamental tenant of spa cover manufacturing. Some companies tape their seams, others use thin nicron-wire hand sealers that only seal 24"-36" at a time forcing them to piece their seals together. Our manufacturer has invested in a heavy-duty, 9' impulse heat-sealer. With this we are able to not only make a complete seal, but also produce a 1/4" weld that outperforms the inconsistent results of hand-sealers. Combined with our 6 mil vapor barrier, our Thermal Guardian spa covers can outperform the competition in fighting water absorption in the foam core.

Fast Delivery more info
Our custom made-to-order spa covers typically ship in 10 to 14 days. Please allow 5 to 7 days for shipment. Need it faster? We offer a Rush Service so it ships in no more than 2 days!

Premium Materials + Superior Technology + Quality Craftsmanship = A Great Spa Cover
The recipe for a great, long-lasting spa cover is simple. You start with Premium Materials. You acquire Superior Technology and assemble a team of experienced Quality Craftsmen and women who are paid to care what the product looks like. Our covers' patterns are cut by Otto. That would be the computerized cutter that doesn't make a mistake within a 1/1000th of an inch. The covers are sealed by a computer-controlled heat sealer that insures a perfect 1/4" wide weld to will keep the moisture out of the foam. There aren't computers that sew the cover, but even better a team of seamstresses tailor your cover to the fit you require.

Thermal Guardian spa covers are available in these 15 colors
