Hot Tub Covers

High quality, long lasting hot tub covers, custom-made for you.

To start the custom hot tub cover process, please refer to the illustrations below and select the shape of your hot tub. Once you've selected the shape, please choose one of the 13 colors you would like your hot tub cover to be. If none of these shapes are accurate or you would like more information about the colors, please contact a Master Spa Parts specialist at 855-308-2149.

When To Order A Replacement Hot Tub Cover

Not sure if it's time to order a new hot tub cover? Check your cover for these key indicators:

  • If the outer vinyl is torn on your spa cover, it will affect the heat retention and cleanliness of your spa water. Cracked vinyl isn’t repaired easily and, unfortunately, with dry and brittle vinyl no repair is possible.
  • A heavy or sagging cover shows that water has been absorbed into the foam core, and a replacement hot tub cover must be ordered. Foam cores are critical for heat retention and safety.
  • Other smaller issues can arise such as broken straps and locks, torn hinges, or unfastened stitching, all of which can affect heat retention in your hot tub and your safety.

Please note that along measurement A is where your hot tub cover will fold in half.

Enter Measurements

Measuring your hot tub accurately is important, as it ensures your new custom cover will fit properly.

If your old cover indicates different elements such as make, model or specifications—only use those measurements to confirm your own. Generally, hot tub covers tend to fit better when the owner uses their own measurements. If you like the fit of your current cover, simply measure it and we will replicate that. If you would like it a bit bigger, round your numbers slightly up!

If none of the shapes on this order form match the design of your hot tub or you would like more information in general, please contact a Master Spa Parts specialist at 855-308-2149.

If your measurement falls in between two numbers, round DOWN to make the cover corner a bit larger. Please contact us if your cover measures larger than 96″ in any direction, if your cover has special cut outs for speakers, handrails, or any other special requirements, or if your cover shape was not shown.

Measuring the radius your hot tub cover

How To Use the Carpenter Square: Put the square against the spa at the corner. The radius is the measurement between the inside corner of the square and where the curve of the spa corner first touches the square (shown by the black line).

The standard hot tub skirt (flap) length is 4”– which is the recommended length for most spas. However, at MSP, we can make your hot tub skirt any length you want – from 1” – 10”

Additionally, lockable straps (4) are located on the skirt– falling 3 inches longer than the flap itself. These straps provide resistance against the wind – and are located strategically depending on the shape of your cover.

*If you require a longer strap length or placed in a specific area, please contact us (with a diagram) and we will do our best to accommodate your request.
