Beach Comber makes a good tub, but they make a lot of false claims, number 1 being about the energy efficiency. Most brands use urethane spray foam insulation and most brands use balboa like beachcomber does...So what it is that makes them so much more efficient?
They have a good marketing department
I work at a pool and spa store...we get a lot of old tubs with leaks that need to be fixed, which means cutting and digging out spray foam. I like the ones with thermal blankets, roxul and rigid insulation, much nicer(and cheaper) to work on.
