Is it time to replace your hot tub cover?
A good hot tub cover does much more than keep leaves and debris out of the water.
It helps retain heat, protects the spa when it isn't in use and forms an important part of the hot tub's overall insulation.
Over time, however, covers can deteriorate.
The outer material may become brittle, stitching may fail and the internal insulation can become saturated with moisture.
Knowing when to replace your cover can save frustration and help prevent unnecessary heat loss.
Five signs your cover may need replacing
1. It has become unusually heavy
A significant increase in weight can indicate that moisture has entered the insulating foam.
Once the foam becomes waterlogged, the cover may be difficult to lift and its insulating performance can deteriorate.
2. The outer material is cracking or splitting
Exposure to sunlight, weather and repeated opening can gradually damage the cover's outer material.
Small defects can develop into larger openings that allow water into the insulation.
3. The cover no longer fits properly
A cover may shrink, distort or lose its shape as it ages.
Gaps around the edges can allow warm air to escape.
4. The internal supports are damaged
Broken or weakened reinforcing components can affect the cover's shape and make it unsafe or difficult to handle.
5. The cover is sagging or holding rainwater
A badly deformed cover may no longer shed water effectively.
Standing water adds weight and may accelerate deterioration.
Stock covers or made-to-measure?
Some hot tubs use common dimensions, making a standard replacement cover a practical option.
Others require a bespoke cover because of their shape, corner radius, dimensions or folding arrangement.
Even two hot tubs described as the same size may require different covers.
That's why it's important to confirm the measurements rather than ordering solely from an approximate external dimension.
How to measure your hot tub cover
Important: The correct measurement method depends on the cover manufacturer and whether you're measuring the existing cover or the hot tub shell. Always follow the supplier's instructions.
Length and width
Measure the dimensions required by the cover supplier, keeping the tape straight and recording measurements carefully.
Do not assume the existing cover is still its original size if it has shrunk or distorted.
Corner radius
Many square and rectangular hot tubs have rounded corners.
The radius describes the curvature of those corners, and it can make a significant difference to the fit of the finished cover.
A straightedge and measuring tape can help establish the radius, but use the supplier's recommended method.
Folding direction
Check which way the cover should fold.
This is particularly important if you use a cover lifter or have limited clearance around the hot tub.
Skirt or drop
The skirt is the section of material that hangs down around the edge of the hot tub.
Its required depth depends on the shell and cover design.
Thickness and taper
Covers are available with different insulation thicknesses and profiles.
The appropriate specification depends on the hot tub, climate, handling requirements and supplier options.
How much does a replacement hot tub cover cost?
Prices vary according to dimensions, shape, materials, insulation, construction and delivery arrangements.
Made-to-measure covers may cost more than standard sizes, and production lead times can vary.
Rather than relying on historical prices from older articles, we recommend obtaining a current quotation for your particular hot tub.
The cheapest cover is not necessarily the best value if it fits poorly or provides inadequate insulation.
Should you replace the cover lifter too?
Not always.
However, if the old cover has become very heavy or the lifter is damaged, it is worth checking that the lifting mechanism is still suitable.
A replacement cover should be compatible with the existing lifter and the space around the spa.
Can Spa Simple help you find the right cover?
Yes. We can help customers explore suitable replacement cover options.
When making an enquiry, it helps to include:
- Your hot tub's make and model, if known.
- Approximate dimensions.
- Photographs of the hot tub and existing cover.
- The folding direction.
- Any details of an existing cover lifter.
We can then advise on the information needed for an accurate quotation.
