Spa/Hot Tub Measure Guide
Note: You will receive a complete drawing of your cover for your approval before your order is finalized.
Replacing an existing cover:
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. When measuring your cover, measure the overall length. Ignoring the corners and center hinge.
Measuring for a new square or rectangular cover

Three measurements are required for a square/rectangular spa or hot tub.
A-Measure (across the hinge)
B-Measure (parallel to the hinge)
Corner radius for rounded corners
It's important to know the hinge direction you want to have on your cover. When you determine the direction you want your cover to fold, take the A-Measurement - the dimension ACROSS the hinge. Measure to the outside edge of the top of the spa. When measuring the shell of your hot tub, measure to the outside edge of the acrylic lip so the cover will be big enouugh and the skirt will hang correctly.
Next, take the B-Measurement - the dimension PARALLEL to the hinge. Measure to the outside edge of the top of the spa. When measuring the shell of your hot tub, measure to the outside edge of the acrylic lip so the cover will be big enouugh and the skirt will hang correctly.
3. Corner Radius Measure:
An easy way to measure a corner radius is to use a carpenter square (pictured below). Place the square against the outside corner of the spa. The point where the corner curve first touches the carpenter square is the corner radius.
If your measurement falls between full inches, round the radius dimension DOWN to the nearest inch. In this picture, the hot tub radius is exactly 9.5" but you can see how a cover made to 8" or even 7" radius will give a little leeway on the fit. Making the cover corner a bit larger does not impact the insulating performance (R-value) of the cover. If you would like help measuring a hot tub cover with rounded corners, watch the 1 minute video below.
