The Tepid Baths are historical indoor public pools in Auckland, New Zealand. Built in 1914 on the previous site of a small drydock, Tepid Baths was originally leased from the Auckland Harbour Board, and contains two separate pools, a "male" (25 m, 6 lanes) and "female" (18 m, 4 lane). The "male" pool was the largest pool in New Zealand at that time. The pools were heated via hot water from the nearby tramways power plant, and the system was considered an engineering masterpiece of the time.
