Hudson Bay Spas Replacement Hot Tub Covers

What size AIRCAP 1™ fits your Hudson Bay hot tub?

Hudson Bay is an LPI, Inc. brand from Johnson City, Tennessee, sold factory-direct through Aqua Living Factory Outlets, LPI’s own store. The brand site’s catalog is offline at the time of writing, so the figures here come from the Aqua Living product pages and LPI’s spec sheets, which agree on every model. The X-12 is 92" × 92" and takes the AIRCAP 1™ X-Large (fits 92"–94"). The HB30 at 80" and the HB29 and HB34 at 79.5" — the same six-seat shell with 29 and 34 jets, and 79.5 rounds up to 80 — take the X-Small (80"–82"). Sister LPI brands are on our Catalina, Water’s Edge and Home and Garden pages.

Eight Hudson Bay models are not listed. The HB19 and X-3 are square but 76" × 76", an inch under our smallest size, and the HB31 is a 72" square. The HB14C is a corner triangle whose two 71.75" figures are its legs, not a square. The HBSL (35.75" × 79.5"), HB15 (59" × 69"), HB18 (61" × 81.75") and X-6 (78" × 84") are rectangles. Hudson Bay sells no swim spas.

Dimensions are taken from the Aqua Living product pages and the LPI spec sheets dated 2025 (September 2026); every Hudson Bay shell has a 6" corner radius. 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.
