Marquis Spas Reward (2012–2021) Replacement Cover

The AIRCAP 1™ comes in six sizes covering square spas from 77" to 94". Each size is built to overhang its band slightly — that is how a spa cover is meant to sit — so the Medium, which fits cabinets 86"–88", covers the Reward (2012–2021)'s 85.5" x 85.5" shell with the right overhang once that measurement is rounded up to 86", as a cover size always is.

At 85.5" the Reward (2012–2021) sits just under the Medium's 86"–88" range and rounds up into it. A cover has to overhang the shell, never stop short of it, so the rule is always to round up. No other Marquis Spas model in the Spa Fitter has the Reward (2012–2021)'s 85.5" x 85.5" cabinet. The 26 Marquis Spas models we fit sit on 6 footprints, and the Reward (2012–2021) is on number 4 of 6 from the smallest; together they span 5 of the six AIRCAP 1 sizes.

Cabinet dimensions can change between model years. Before ordering, measure your Reward (2012–2021) at its widest point across the top, in both directions, including any acrylic lip that overhangs the cabinet — the SureFit™ guide walks through it in two measurements. If a figure you have found elsewhere is larger than ours, an overhanging lip is the usual reason. If your spa measures between two sizes, round up.

A 85.5" x 85.5" footprint rounds up to 86" × 86", and every spa we list at that measurement is on one page: hot tubs that take an 86" × 86" cover — the same AIRCAP 1™ Medium, at the same price.

How the AIRCAP 1™ is built

Instead of a rigid foam core wrapped in vinyl, the AIRCAP 1™ uses welded drop-stitch construction: a sealed air chamber with no foam to absorb water, so it does not become the waterlogged two-person lift that ends most foam covers. More on how it insulates, how it holds up, and why it is foam-free — or estimate what your current foam cover weighs.
