Measuring Tips

Getting the fit right

Measure with confidence.

A few careful measurements help us make a replacement cover that fits your spa. Start here before completing your order.

Your measurements are the finished cover size.

We build to the dimensions you provide. We do not add extra material or automatically adjust the size for fit. We review your measurements and contact you if something looks wrong, but make and model alone cannot confirm the dimensions of your spa.

Measure the old cover or the spa?

If your old cover is intact and fits well, measure it. Working with a second person makes it easier to keep the tape straight and read accurately.

If the cover is damaged, distorted or missing, measure the spa itself. The dimensions you order must allow the fit you want. Contact us before adding clearance to a cut-corner shape: changing the overall size also changes the corner measurements.

What about a wooden lip?

You can choose whether the cover extends over the wooden lip. Measure the outline you want the new cover to cover.

If you want the skirt to hide the lip too, include that depth when choosing the skirt length.

Choose the skirt length

The skirt is the vinyl flap hanging below the cover. Its length is a cosmetic choice, rather than an insulation setting.

Measure from the top of the spa down to where you want the skirt to end. Most skirts cover the acrylic shell without extending farther down the cabinet.

Measure the corner radius

The radius describes the curve of a rounded corner. It is not the distance around the curve.

Use a framing square, or straightedges and a tape measure, to find it.

Don’t see your shape?

The online builder includes the most common cover shapes. For a different outline, call us before ordering so we can explain which measurements we need.

Speaker or control cutouts

Cutouts need extra measurements to show their size and position. Contact us for measuring instructions before placing an order for a cover with cutouts.
