spa cover measuring tips

When measuring your spa for a new spa cover, there is one important thing to remember: IT HAS TO BE LARGE ENOUGH TO FIT! We can make you a cover in one of two styles. The most popular style is to cover only the acrylic shell. (measurement C in the below diagram).

If you have a spa that resembles the diagram below, with a wood edge on the outside of the acrylic shell, and would like your new lid to cover both the shell and the wood lip, MEASURE FROM THE OUTSIDE OF THE WOOD SKIRT (D "Cabinet Size").

There is no difference in spa cover performance either way. It is simply your preference.

A - This is the height of the acrylic lip. This will determine the cover�s skirt length ("Cabinet Size" covers may require a longer skirt, to the bottom of the "deck").

B - Width of wood lip of the cabinet (not present on all tubs).
C - Outside dimension of the acrylic shell (standard cover size).
D - Outside dimension of the wood cabinet.

Some covers have rounded corners. The diagram above shows a rounded corner with imaginary dotted red lines. The length of the red line represents the measurement of the radius corner. The lines start where the cover begins to curve, and end where they cross. Be sure to measure all corners and that they are ALL the same size! IMPORTANT: If in doubt, a slightly smaller radius will slightly over hang the spa while a larger radius will not cover the spa completely.

Some covers have cut-corners. The diagram above shows a cut corner with the length of the redline representing the measurement of the cut-corner. Be sure to measure all corners and that they are ALL the same size (some covers have different cuts)! IMPORTANT: If in doubt, a slightly smaller cut-corner will cause the cover to slightly over hang the spa while a larger cut will not cover the spa completely.

When measuring an octagon spa, it is extremely important to get dimensions on all sides of the tub.

The example above shows an octagon (eight sides). Its length & width measurements (9 & 10), and the side measurements (1-8), are ALL EQUAL. If they are not equal, it is not a true octagon, but more than likely a cover with cut corners.

More measuring tips:

• Measure both your spa and your old cover, if possible.
• Make sure the measurements are big enough. It is okay for the cover to be big. It still does its job. However, a cover too small will never do the job it is supposed to.
• Measure all sides of the spa.
• Measure the overall length and width of the spa.
• Be careful when representing the dimensions in our order forms.
• Specify hinge direction.
