Fiberglass has been used in swim
spas, hot tubs and swimming pools for over 45 years. It is so durable that we offer a
lifetime warranty on the WonderSpa™’s fiberglass shell. Fiberglass never needs
costly replacement vinyl liners or acid washing and replastering like concrete does.
Chemical costs are less because of the nonporous surface of fiberglass and fiberglass
retains its luster far better than vinyl liners or concrete. Virtually maintenance free,
fiberglass is still 17 times stronger than concrete. |
