Read the warranty card before you sign: labor after year one, travel charges, and whether coverage moves to a second owner. The hot tub warranty comparison lines up every brand.

Bullfrog Spas posts only a series range for the A6L and A7L: $12,095–$26,395 (maker's A Series starting prices, Oct 2026). Delivery, the pad, the electrician and the cover lifter are extra. Each model's price and where it comes from: Bullfrog A6L price and Bullfrog A7L price.

• Sit in both, dry is fine, in the seat you would use most. On a running display tub, feel the jets with the back of your hand. Seat depth and where the jets land matter more than the count.
• Climb in and out: step height and the lounger's length suit some bodies and not others.
• Ask for each model's California Energy Commission listing and the warranty card.
• Lie back in the lounger, dry is fine. If your feet don't reach the end of the footwell or your head sits low, it will not suit you.
