Sundance Spas Hanover 780 Replacement Cover
The Sundance Spas Hanover 780 takes the AIRCAP 1™ Small — a foam-free replacement hot tub cover for square spas 83"–85". The Hanover 780's cabinet measures 84" x 84", inside the Small's range. The cover weighs 35–40 lb for life, costs $1,195, is engineered to comply with ASTM F1346-23, and carries a 3-year limited warranty.

Why the Small fits the Hanover 780
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 Small, which fits cabinets 83"–85", covers the Hanover 780's 84" x 84" shell with the right overhang.
At 84" the Hanover 780 sits mid-band in the Small's 83"–85" range, 1" off the bottom and 1" off the top. Within Sundance Spas, the Hanover 780 shares that 84" x 84" cabinet with Altamar 880, Bristol 780, Edison 680 and Peyton 680 — same footprint, same cover. Sundance Spas builds the 19 models we fit on 5 footprints, and the Hanover 780 is on number 3 of 5 from the smallest; the line spans 5 of the six AIRCAP 1 sizes.
Cabinet dimensions can change between model years. Before ordering, measure your Hanover 780 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.
Every spa in our catalogue that measures 84" x 84" is on one page: hot tubs that take an 84" × 84" cover — the same AIRCAP 1™ Small, 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.

Sundance Spas Hanover 780 cover: common questions
What size hot tub cover fits the Sundance Spas Hanover 780?
The Sundance Spas Hanover 780 takes the AIRCAP 1 Small, which fits square hot tubs measuring 83"–85" across. The Hanover 780's cabinet measures 84" x 84", inside that band. Measure your spa side to side across the top of the cabinet to confirm before ordering.
Will the AIRCAP 1 fit a Sundance Spas Hanover 780?
Yes — the Hanover 780's 84" x 84" square cabinet falls in the AIRCAP 1 Small's 83"–85" range, and the Ziptech modular skirt system ships with three skirt lengths so the drop over the cabinet adjusts without a custom order. Cabinet sizes can change between model years, so confirm with two quick measurements.
How much does a replacement cover for the Sundance Spas Hanover 780 cost?
The AIRCAP 1 costs $1,195 in every size, including the pump, three Ziptech skirt lengths, and tie-down straps, with free US shipping and 30-day returns. Unlike a foam cover it has no foam core to waterlog, so it stays at its original 35–40 lb weight for life.
How heavy is a replacement cover for the Sundance Spas Hanover 780?
The AIRCAP 1 Small weighs 35–40 lb and keeps that weight permanently — its sealed drop-stitch air core cannot absorb water. A foam cover starts at 40–75 lb and gains weight as the foam saturates.
