How to measure a spa cover

Taking correct measurements for your spa cover is crucial to ensure you get the perfect fit for your spa. Keep reading to learn more.

Why do I need to provide measurements for my new spa cover?

Manufacturers often change the dimensions of spa pools and swim spas. So even if you know you bought a Vortex Mercury in 2019 (for example), there may be two possible cover sizes for this spa, depending on what run it was produced on at the factory.

We need to know the length, width and corner radius of your spa (or existing cover) to ensure you get the correct size.

Ordering a spa cover without your length, width and corner radius is like going to Mcdonald's and ordering a soft drink. You let them know you want a large and it needs to be carbonated (equivalent to providing the length and width only).

If you don't provide any other details (coke, sprite, diet, radius?) then you may end up unhappy with the result...

The difference, however, lies in the fact that spa covers are nonrefundable and are a larger financial purchase.

How to measure your spa cover correctly

To enable us to recommend a cover that will be the best fit for your spa, we need you to take some measurements of your existing cover.

If you don't have a cover currently, you can follow the steps below to measure your spa.

1. Measure each side

Measure the outside dimensions of your spa. (Do not measure the inside edges)

2. Measure the outer radius

Use two rulers or straight edges on each edge of a corner. Measure from the beginning of the curve (R1) to the point where both rulers or straight edges meet (R2)

3. Measure the lip of your spa

Measure from the top surface of the spa shell down to where it meets the cabinet. For an in-ground spa, measure from the top surface down to the deck, or tile.

4. Measure the location of catches

Measure the distance (T1 & T2) from each outer spa edge to the centre of the catch. If there is more than one catch per side also measure the distance between catches (T3). Then measure from the top of the spa (not the spa cover) down to the center of catch (T4).
