What customers are saying
Awesome product, my kids don’t complain about the cover anymore…
Best $$ I ever spent!
What this company has created in terms of an original and revolutionary product is nothing short of amazing.
For a reasonable price, I can cover my spa with a top that won’t get musty.
Nice and lightweight
…set up was super easy and took about 15 min total.
Installation was a breeze and we love it already!
Great customer service still matters, and frankly, not enough companies deliver it anymore. This company does, and that deserves recognition.
Do not wait to buy one.
Thoughtfully engineered
Three practical reasons to rethink your next hot tub cover.
AirLoc™ panels have no foam core to soak up water, so the cover weighs the same out of the box and years later: 35–40 lb, depending on size.
Learn about water resistanceThe sealed AirLoc™ air core has nothing in it to absorb water, so its insulation stays consistent for the life of the cover.

Water’s Edge is a dealer-channel brand built by LPI, Inc. of Johnson City, Tennessee — the same factory behind Catalina Spas, Dr. Wellness Spas, Hudson Bay Spas and Home and Garden Spas. Ten hot tubs are listed on watersedgehottubs.com and six are square: the Romance 2, Geneva, Laguna, Largo, Serenity and Slumber. Our fitter also lists three older models from the G-series that Water’s Edge sold in about 2012–2013. Here is how the 9 Water’s Edge models in our fitter map to AIRCAP 1™ sizes:
Shells you will find elsewhere in this fitter. Four of today’s Water’s Edge tubs are built on shells we also list under other brands: the top-view photos match, and each pair takes the same AIRCAP 1™ size. The Slumber is the same shell as the Hudson Bay HB29, the Laguna the same shell as the Pinnacle PP755, the Largo the same shell as the Premium Leisure LE 742, and the Geneva the same shell as the Premium Leisure PR 881. Jets and equipment can differ from badge to badge. LPI prints the HB29 at 79.5", which rounds up to the same X-Small as the Slumber’s 80".
Older Water’s Edge G-series models. In about 2012–2013 Water’s Edge sold its tubs under G-numbers, and its own model pages from that time, preserved in web archives, print their sizes. Two of those G-models are today’s tubs under earlier names, with different jet packages: the G12 is the Romance 2 shell and the G6 is the Serenity shell, so each is listed under its later name with the G-number in brackets. Water’s Edge printed the G12, and the Romance 2 in 2013, at 92" square, and has printed the Romance 2 at 93" since 2016; either figure takes the X-Large. The G10 and G11 are printed at 92" × 92" and take the X-Large, and the G7 is printed at 82" × 82" and takes the X-Small. The only top-view photos we have found of the G11 and G7 appear to be stretched sideways, so we list them without a photo, on their printed sizes and the rounded-square outline those photos show; measure yours across the top before ordering. The G3 was a small rectangular tub that no square cover fits. Dr. Wellness, another LPI brand, also uses G-numbers, so go by the brand on your tub. Today’s Dr. Wellness G-11 and G-12 are different shells from the Water’s Edge G11 and G12: they are printed at 91" and take the Large. A Dr. Wellness G-11 or G-12 from about 2012–2013 appears to be the Water’s Edge shell, because a dealer pictured them with Water’s Edge’s own G11 and G12 photos, so measure it: 92–94" across the top takes the X-Large, and 89–91" the Large. LPI has built the Dr. Wellness G-6 on two shells, printed at 84" and 82", and neither is the Water’s Edge G6; it has printed the Dr. Wellness G-7 at both 82" and 84", so the Dr. Wellness page asks owners of either model to measure.
Older tubs we have not listed. The old Water’s Edge site also carried pages, under the Water’s Edge banner, for LG models that appear to come from Life’s Great Spas. We have found no photo or drawing of them, so we cannot confirm which are square. The LG-12000 is printed at 92" × 92": if yours is square and measures 92–94" across the top, it takes the X-Large. The LG-11000, which its page heads “The Romance”, is printed at 8′ × 8′, a whole-feet figure that would be 96", over the X-Large’s 94" limit. If you own one, or a Water’s Edge Romance without the 2, measure it across the top: if it is square and 77–94", it takes the AIRCAP 1™ size whose range covers that figure (89–91" is the Large and 92–94" the X-Large), and if it is over 94", no AIRCAP 1™ size will fit. The LG-3000 (82" × 60") and the LG-5000 and LG-6000 (78" × 84") are printed far out of square, and the LG-4000 is printed at 76" × 76", under our 77" minimum. Waters Edge Spas of Charlestown, New Hampshire, was a different, older spa maker with a similar name, whose website ran from about 2000 to 2010. Its tubs, among them the Pelican, Loon II, Gull and Octo 90 II, are not models of the Water’s Edge brand on this page and are not listed here, and cover retailers’ “Waters Edge” model lists mostly name that line. If you own one and it is square, measure it across the top before ordering; the Octo 90 II is an octagon and the Gull is printed at 6′6" × 7′, out of square, so no square cover fits them.
Four of today’s Water’s Edge hot tubs are not square and no AIRCAP 1™ size will fit them. The Duet is listed at 76" × 76", but those are the two legs of a corner spa with a long diagonal front, and 76" is under our smallest size in any case. The Le Circ is round — its 78" is a diameter. The Trio (80" × 63") and Great Escape (70" × 80") are rectangles. Water’s Edge sells no swim spas today; the 12′5" and 16′5" swim spas it listed from 2013 until at least 2019 are far outside a square cover’s range.
Dimensions for today’s models are taken from the SIZE line on each Water’s Edge product page (checked October 2026), and for the G-series from Water’s Edge’s own model pages of about 2012–2013. LPI’s spec-sheet index carries no Water’s Edge sheets, so those pages are the only figures Water’s Edge itself prints; where a shell is also sold under another brand, that brand’s printed size gives the same cover size. Cabinet sizes can change between model years, so measure your spa side to side across the top of the cabinet before ordering; the SureFit™ measuring guide walks through it in two measurements. If your measurement falls between two sizes, round up.
