Lifesmart Replacement Hot Tub Covers

What size AIRCAP 1™ fits your Lifesmart hot tub?

Lifesmart sells fifteen hot tub models through Home Depot, Lowe's, Wayfair and its own store, and three of them fit an AIRCAP 1™ — the brand's 7-person square shells, which all share one 81" x 81" footprint. That makes sizing unusually simple: every square Lifesmart takes the same cover.

Here is how the 3 Lifesmart models in our fitter map to AIRCAP 1™ sizes:

• The LS450DX (110V plug-and-play, 22 jets), the LS600DX (230V, 65 jets) and the LS700DX (230V, 90 jets) each measure 81" x 81" and take the AIRCAP 1™ X-Small, which fits square spas 80–82". An 81" shell sits right in the middle of that range.

One naming note for Home Depot shoppers: the LS600DX is sold there under the name Coronado DX (the listing spells it "Coranado DX"). If that's the name on your receipt, it's the same 81" square spa — it takes the X-Small.

Every AIRCAP 1™ ships with the Ziptech™ modular skirt system, so you can zip on the right skirt depth for your cabinet instead of ordering a custom cover.

Not every Lifesmart takes a square cover. The Sereno is a true square at 75" x 75" but sits below our smallest size. The LS100 and LS100DX (70" x 61"), the LS350DX and LS350 Plus (72" x 81"), and the LS500 Plus, LS550 Plus, Tierra and Leganza (all 77" x 87") are rectangular shells; the LS200 and LS200DX — sold at Lowe's as the Key Largo — are round; and the LS300 Plus is a 2-person corner triangle. The square AIRCAP 1™ doesn't fit those shapes. Lifesmart is a Watkins Wellness brand, the company behind Hot Spring and Caldera — two more brands in our Spa Fitter. Cabinet sizes can change between model years, so measure your own spa before ordering — the SureFit™ measuring guide walks through it in two measurements, and works for any hot tub, Lifesmart or not.
