How to secure a hot tub cover in the wind

How inflatable tub covers fasten

Most inflatable tubs have a lid with a skirt that drops over the top of the wall, held by buckles or clips that link the lid to loops on the tub. Some have a zip as well. Many Lay-Z-Spa lids have locking buckles that need a key or tool to open, which also helps keep children out.

Each clip takes a share of the load. If one is undone or broken, the wind has an edge to get under, and the rest are quickly overloaded.

Step by step: securing the cover

1. 1

   Seat the lid evenly so the skirt hangs straight all round.

2. 2

   Make sure the inflatable bladder, if fitted, is firm and sitting on the water.

3. 3

   Fasten every clip or buckle and lock any with locks.

4. 4

   Check straps are snug without straining the loops.

5. 5

   In exposed spots, add wind straps over the top of the cover.

6. 6

   Clear loose garden items near the tub that could be blown against it.

Adding wind straps

Hot tub cover straps are adjustable straps that pass over the cover and fix to anchors. On an inflatable tub, you can often run them under the tub base or to ground anchors beside it, so they hold the lid down without pulling on the wall's own loops. Hard shell tubs use straps fixed to the cabinet.

Choose straps made for hot tubs or outdoor use, with weatherproof buckles. Keep them snug, not tight enough to dent the cover. Remove or loosen them before lifting the lid.

Note:Never fix anchors into the tub wall or floor. Keep straps clear of the pump unit, cables and RCD plug.

Replacing a broken clip

Clips and buckles wear with sun and use. Most makers sell replacement buckle sets for their lids. Note the model number and the clip type, then fit the new clip as shown in the instructions; many slide or thread onto a webbing strap.

If the loop on the tub wall is torn, do not glue a clip straight onto the PVC. Ask the maker about repair options. A temporary wind strap can hold the lid down until it is fixed.

Cutting the wind

Less wind also means less heat loss. See how to insulate an inflatable hot tub.

• Place the tub where a fence, wall or hedge breaks the prevailing wind.
• Add a screen or a gazebo with side panels.
• Keep the lid fastened even for short breaks.
• In a storm warning, add straps and consider lowering the bladder slightly so the lid sits lower.

Covers that hold well

Heavier foam lids and well fitted thermal covers are less likely to lift than a light lid with a soft bladder. If you are choosing a tub for an exposed garden, look at models with foam lids or firm covers. Our winter hot tub guide notes which have them.

Look after the cover itself too; see how to clean and protect a hot tub cover.

Checking the cover after a storm

After high winds, walk round the tub and check every clip, strap and seam. Look for tears where the skirt meets the lid, a bladder that has lost air, or debris that has worked its way under the edge. Skim out leaves and test the water, as storms often wash dirt and rain into the tub.

If the lid did lift, check the water level and the pump unit. Rain can dilute sanitiser, so retest and adjust before the next soak. See how to add chemicals to a hot tub for the order to follow.

Storm damage is also a good moment to look at the overall state of the lid. A cover that keeps lifting may be past its best; see how long hot tub covers last.

Frequently asked questions

How do I stop my hot tub cover blowing off? Fasten every clip, keep the lid firmly seated, add wind straps in exposed spots and shelter the tub from the wind.

Can I buy replacement clips for my cover? Most makers sell buckle sets for their lids. Match the clip type and your tub's model number.

Do wind straps damage the cover? Not if they are snug rather than tight and made for outdoor use. Over tightening can dent or wear the cover.

Should I leave the cover on in a storm? Yes, fastened and strapped. A cover off in a storm lets debris into the water and may be damaged.
