Edge-to-Edge Insulation®
Edge-to-Edge Insulation®: more heat = lower power bills
The defining feature of a hot tub is warm water, and when you choose a spa with Edge-to-Edge Insulation®, an exclusive, full cavity insulation from Hot Spring, you’ll enjoy more heat, and save money on energy costs in the process.
Dense, flexible, ultra-efficient insulation
From the wool-like FiberCor® found in our Hot Spot and Limelight collections (4x denser than standard foam), to the unmatched multi-density foam of our Highlife spas, our Edge-to-Edge Insulation® is a key reason why we’re the most energy efficient spa brand in Australasia. Leaving no gaps or thermal voids, and denser than the rest, your water stays warmer in a Hot Spring.

Answering your spa insulation questions
“The feeling of having your warm spa, on a cold night, is beautiful. My kids are already grown and already left home, but they come in here from time to time and we have a family get-together.”
Always ready, easy to maintain
Edge-to-Edge Insulation® keeps your water at the precise temperature you set while using minimal power, so your spa is always ready to host a soak. And if internal machinery ever needs to be serviced, this insulation is very easy to remove and replace.
