Dr. Wellness Spas Replacement Hot Tub Covers

Dr. Wellness is a brand of LPI, Inc. of Johnson City, Tennessee, the same factory behind Hudson Bay, Catalina, Water’s Edge and Home and Garden — all four of which are already in this fitter. Fifteen Dr. Wellness models take an AIRCAP 1™ in our fitter, spread across four sizes, including older models and both versions of the G-6.

Here is how the 15 Dr. Wellness models in our fitter map to AIRCAP 1™ sizes:

• The STR-34 and G-6 (2025 and later) each take the AIRCAP 1™ X-Small, which fits square spas 80–82". The STR-34 measures 79.5", which rounds up into this size — LPI prints that same shell as both 79.5" and 80" in its own paperwork.
• The G-10K, G-7, G-6 (2024 and earlier) and G-5000 each take the AIRCAP 1™ Small, which fits square spas 83–85".
• The G-9, G-11, G-12, G-13, G-14 and G-8000 each take the AIRCAP 1™ Large, which fits square spas 89–91".
• The G-20K, X-11 and X-12 Lifestyle each take the AIRCAP 1™ X-Large, which fits square spas 92–94".

G-6 and G-7 owners: measure across the top before ordering. LPI has built the G-6 on two different shells. Its December 2021 sheet prints the G-6 at 84" x 84", on a shell with a lounger across one side and the filter in a corner; that is our G-6 (2024 and earlier), and it takes the Small. Its 2025 sheet prints the G-6 at 82" x 82" x 35.75", on a shell with an octagonal footwell and a large lounge pillow in one corner; that is our G-6 (2025 and later), and it takes the X-Small. LPI’s sheets do not pin the year the shell changed, so go by the tape measure rather than the year: 80–82" across the top takes the X-Small, and 83–85" the Small. LPI printed the G-7 at 82" on its December 2021 sheet and at 84" on its 2024 sheet, so measure a G-7 too: 80–82" takes the X-Small, and 83–85" the Small. Water’s Edge, another LPI brand, also sold a G6 and a G7 in about 2012–2013; they are on our Water’s Edge page, so if your tub is a Water’s Edge, use that page.

G-11 and G-12 owners with a tub from about 2012–2013: measure across the top. Today’s G-11 and G-12 are printed at 91" and take the Large, but those sold around 2012–2013 appear to have been different, larger shells. A Dr. Wellness dealer’s listing from that time pictures its G-11 and G-12 with the same photos that Water’s Edge, another LPI brand, used for its G11 and G12, which Water’s Edge printed at 92" square; today’s G-11 and G-12 have different layouts. If yours measures 92–94" across the top, take the X-Large. The Water’s Edge tubs in those photos are on our Water’s Edge page: the G11, which we list without a photo, and the G12 under its later name, Romance 2 (G12). The photos on our G-11, G-12, G-13 and G-14 rows are from LPI’s December 2021 sheets; LPI’s current sheets show different shells for all four, still printed at 91", so a newer one takes the Large too.

Lifestyle series: X-11 and X-12. LPI prints the X-11 at 92" x 92" x 36" on its June 2022 and June 2024 sheets, so it takes the X-Large. 92" is the bottom of that size, so measure an X-11 across the top before ordering, especially one from before 2022, the date of the earliest X-11 sheet we have found: 92–94" takes the X-Large, and 89–91" the Large. The X-12 Lifestyle is printed at 92" x 92" x 36" on LPI’s November 2022 sheet and takes the X-Large too; we list it without a photo. It is the same shell as the tub on our Hudson Bay X-12 page: LPI’s own top-view photo of the Dr. Wellness X-12 shows that shell, and Dr. Wellness’s own site now sells it as the Hudson Bay X-12 Lifestyle Spa. LPI’s November 2022 sheet pictures the same seat layout with a different set of jets, so measure a Dr. Wellness X-12 from before 2023 across the top before ordering: 92–94" takes the X-Large, and 89–91" the Large.

G-8000 and G-5000 owners: check for Tuff Top brackets. LPI’s sheets list a Tuff Top among the G-8000 and G-5000 features: a hard cover that mounts on hinge brackets fixed to the cabinet. If your tub has a Tuff Top, check that those brackets will clear the AIRCAP 1™ and its skirt before ordering, or remove them. The photos on our G-8000 and G-5000 rows are from LPI’s June 2022 sheets, with the Tuff Top and its hinge hardware edited out.

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.

Models the AIRCAP 1™ does not fit: the G-2000 looks square on paper at 77" x 76.75", but those two figures are the bounding box of a corner spa — it is a five-sided three-seat wedge, not a square, so no square cover will fit it. The G-1700 (114" x 92"), G-2 (79" x 63") and G-100 (82" x 69.5") are rectangular. The Lifestyle X-2 (60" x 82") and X-5 and X-6 (78" x 84") are rectangular too, and the X-3, which LPI’s 2025 sheets title a Hudson Bay model, is printed at 75.25" x 75.25" on one of those sheets and 76" x 76" on the other, under our 77" minimum either way. The E-8 (Exofit) is an exercise spa, 57.5" tall and sold with its own locking hard cover; like the S-12 and S-16 swim spas, it is not part of this fitter. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.

Dr. Wellness models to measure first. The G-21 (2025) has no LPI spec sheet we can check, and Dr. Wellness names listed for sale in about 2013 — the G-60, G-15, G-16, G-110, C-1000, C-2000, C-5000, C-6000 and X-100 — have no size we can find, so measure any of these across the top before ordering.

A note on where these figures come from. They are read from LPI’s own spec sheets — the current ones published at the factory’s sheet index, and dated earlier sheets for the older rows — rather than taken from the Dr. Wellness product pages, for two reasons. Each product page shows two “Additional Information” blocks, the second belonging to a different spa further down the page; and the PDF each page links is in several cases the December 2021 revision rather than the current one. 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.
