All this solar powered, freestanding bathe wants is a faucet-water source and daylight. The 2.1-gal. water-storage tank heats water as much as one hundred forty§F; when you find yourself ready to shower off chlorinated or salt water, merely adjust the incoming chilly-water dial to the best temperature (up to 16 gal. of 86§F water). No plumbing required; straightforward assembly; breaks apart for storage/transportation. China.
