Pick the Right Hot Tub Cover for Any Size or Shape of Home Spa

Hot tub covers range from inexpensive soft vinyl to heavy duty "walk on" styles. Which hot tub spa cover is worth paying more for?

Looking for a cheap cover

The least expensive hot tub covers are made from double sided polyvinyl with a non woven polypropylene middle layer. Make sure there are sufficient tie downs and childproofed keyed locks to keep children safe.

Look for lightweight materials that come with an inflatable bladder so rain and snow can run off the sloped surface. These covers are affordable, straightforward to use, and easy to store.

Tough outer shell

A classic tapered hot tub cover is made from marine grade PVC vinyl that is treated with mildew, UV and cold crack inhibitors. A breathable industrial grade mesh scrim on the bottom side allows moisture to drain. A polyester reinforced backing will last much longer than cheap cotton material.

Comparing quality

Enclosed between these is a layer of dense, insulating foam. Cheaper versions are manufactured with reground foam and thin plastic wrapping that is not effective at keeping water out. A virgin foam core is less prone to water saturation especially when it is wrapped in 4 mil poly with a vapor proof, vacuum-heat seal.

What else to look for

Center channel reinforcements made from galvanized steel or tempered aluminum increase the strength of the hot tub cover so it won't sag or break under the weight of snow. Corrosion proof zippers allow easy access to the inserts.

A double stitched perimeter apron keeps heat and moisture in. Lock down straps clip in place to stop high winds from blowing the outdoor spa cover off.

Checklist for durability and long life:

reinforced handles
a double reinforced hinge that is sealed off to avoid moisture loss and conserve energy
bonded stitching
fiberglass reinforcement
hinge steam blockers
ensure that the product meets or exceeds ASTM standards

Removing a cover for a hot tub can be a chore. Some accessories make that job easier. Use a system that rocks the cover off and keeps it folded and protected at the side of the tub. If you want to uncover only half of the hot tub, use specially made spa cover lifts that brace and support the open cover.

One person operation is simple with a lift that holds without putting stress on the hinges. Make sure the hot tub cover lift you purchase works with round, octagon, square or unusual shapes and is suitable for flush mount or gazebo spas.

Take care of your hottub cover and it will last

Protect the cover with 303 Protectant - a unique product developed for the aerospace industry. It bonds with vinyl surfaces to guard against ozone damage, cracking, brittleness and discoloration.
