What size AIRCAP 1™ fits your Bullfrog Spas hot tub?
Bullfrog Spas is built around the JetPak system, and its cabinets fall into clear size bands. The A-, R- and X-Series 7-seat models — the A7, A7L, A7D, R7, R7L, X7 and X7L — occupy the middle of the AIRCAP 1™ range, while the 8-seat A8, A8L, A8D, R8, R8L, X8, X8L and the M8 are the largest. The compact Calm series anchors the other end: the 78" Calm6 is the smallest Bullfrog model we fit, and the only one in the line-up that takes our smallest cover size.
Here is how the 19 Bullfrog Spas models in our fitter map to AIRCAP 1™ sizes:
- The Calm6 takes the AIRCAP 1™ XX-Small, which fits square spas 77–79".
- The Calm7 and Calm7L each take the AIRCAP 1™ Small, which fits square spas 83–85".
- The A7, A7L, A7D, R7, R7L, X7 and X7L each take the AIRCAP 1™ Medium, which fits square spas 86–88".
- The M7 takes the AIRCAP 1™ Large, which fits square spas 89–91".
- The M8, A8, A8L, A8D, R8, R8L, X8 and X8L each take the AIRCAP 1™ X-Large, which fits square spas 92–94".
A trailing letter in a Bullfrog model name changes the seating, not the cabinet. The Calm7L is the lounge version of the Calm7 on the identical 84" square shell, just as the A7L, A7D, R7L and X7L share their shells with the A7, R7 and X7, and the A8L, A8D, R8L and X8L with the A8, R8 and X8. An L is one lounger and a D is two. Lounge or bench, the cover is the same.
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.
Not every Bullfrog Spas model takes an AIRCAP 1™. The X6R is a round tub, so a square cover cannot replace its cover. The M6, M9, A5D, A6, A6L, A9L, X5L and X6L all have rectangular cabinets, as do the STIL5 and STIL7 — the STIL7 is only 4" out of square, but that is still too far. And the S150, S180XD and S200 are swim spas, far beyond any hot tub cover. The SportX 162 is the one model we leave off for a different reason: it is a genuine 88" square, but the 2003–2012 SportX cabinets were built with a 15.5" corner radius against 4–8" on every later Bullfrog, so a square cover cut for the modern corner overhangs a SportX at the diagonals. Measure yours and use the SureFit guide. The AIRCAP 1™ is built for square cabinets from 77 to 94 inches.
Measure your own spa before ordering — cabinet sizes can change between model years. The SureFit™ measuring guide walks through it in two measurements, and works for any hot tub, Bullfrog Spas or not.
