No. Although almost all acrylic hot tubs do require expensive electrical work to install, a Softub spa is designed for anyone to install on their own, as it plugs into a standard 220V/ 240V (50 Hz) 10 Amp household electric outlet. And, with our SmartChip™, you never have to worry about power surges or brown-outs damaging your Softub spa, as this built-in RCD will protect it.
