Measure the shell.
Record inches, edge to edge. An old cover can be measured if it still fits well.

Every edge.

A custom spa cover begins with your shape. Turn it, open it, dress it in any of twenty-one real finishes, then make it yours.

Swatch photographs are actual materials; screens vary, so confirm your colour with Pool Busters before ordering. The 3D cover is an illustrative preview, not a cutting template.

Measure the spa, not the sag.
Record the outside-to-outside dimensions of the spa lip. An old stretched or waterlogged cover is not a reliable template.

Let's get the fit right.
Start with what you know. Leave uncertain details for us to confirm.
Before you measure: three details that matter
Check the corners.
Rounded corners need a radius. Cut corners need their own measurement. Leave uncertain details for us to check.
Match the details.
Note the fold and skirt. Have photos of the spa, old cover and model plate ready for confirmation.
When your cover
has had its day.
Heavier than it used to be?
A noticeably heavier cover can indicate a waterlogged core. A dry foam core holds heat; a damaged vapour barrier can let water in.
A sagging centre?
Rain and snowmelt can pool in a sagging cover. Tapering from the hinge towards the outside helps water run off.
A worn hinge or skirt?
The hinge and skirt can let warm air escape. HST options include a full centre seal and overlap skirt.
Not sure it needs replacing? Have photos of the spa, cover and model plate ready, and speak with Pool Busters.
Good care goes
with a good cover.

Cover questions.
Covers
How do I order a replacement hot tub cover?
Use the Custom Spa Cover configurator: brand, model, year, shape, measurements, taper, skirt, fold, colour and any upgrades — the same details HST Synthetics builds from. Pool Busters checks it, quotes it, and confirms the measurements with you before ordering.
How do I measure a spa cover?
Measure the spa shell edge to edge, in inches: A is one side, B the other, and C is the cut corner or the corner radius on shapes that have one. The configurator shows a drawing for each shape. If the old cover fits well, measure that instead. Not sure? Send us photos and we'll measure with you.
What if I don't know my hot tub model?
Look for a label inside the equipment door or on the cabinet near the control pack; it usually carries the brand, model and year. Failing that, a photo of the whole spa from above and of the label plate is enough for us to identify most spas.
Can you make a cover for a non-Equinox spa?
Yes. HST covers are made to measure for any brand, including swim spas and multi-panel covers. The configurator asks for the brand, model and year so we can cross-check the measurements.
