Length and width

If you like the fit of the cover you are replacing, simply measure your cover and we will make your new cover the same size. If not, you can easily measure your hot tub itself by measuring the length and width to the outside edge of the top of the spa.

Provided manufacturer sizes

You can check your measurement against the sizes on our web site which were provided by the spa manufacturers. If they differ, we have found the best fit comes from submitting your measurements.​


  • Remember if you want to add some slack, adding 1 inch will create 1/2 inch slack on each side.
  • If you want to use the manufacturer supplied size, we recommend measuring your cover or spa to confirm the cover will fit properly using their size.

Q. Should I measure my old hot tub cover or the hot tub itself?

A. If you like the way your hot tub cover fits, measure the cover. However, if your current cover is warped or damaged in any way, we recommend you measure the hot tub itself. Hot tub covers have a tendency to shrink over time, so measuring the acrylic tub is the best way to get the correct measurements and hot tub covers that fit perfectly.

Q. Where should I measure?

Measuring your cover    Measuring your hot tub

A. Measure the length and width, AT THE WIDEST POINT. Round up every measurement to the nearest half inch.
B. BE SURE to note where the measurement lines start and end for the hot tub shape you have.
C. The general rule is: if a cover is a little too big, it will fit fine. If it is a little too small, it won't be a hot tub cover.

Q. I have areas on my hot tub that are raised. How do I order?

A. We can make hot tub covers with air buttons, head rests, control panels, handles, etc. that are raised above the lip and require custom cut-outs and recesses. A detailed explanation will be required and an additional charge is necessary. Please contact us for further information on these types of hot tub covers.

Q. How do I specify where I want my cover to fold?

A. We can manufacture your spa cover to fold either side in half.

  • Fold shorter side in half    Show Me
  • Does not matter (Length = Width or Shape is round)    Show Me
