The warmest indoor swimming pool in Melbourne is the hydrotherapy pool at Melton Waves, which is kept at a toasty 36 degrees celsius. This is two degrees warmer than most warm water / hydrotherapy / program pools in Melbourne. The pool is so hot because it is connected to the adjacent spa pool, which is also included in the entry price. The hydrotherapy pool is roughly 10 m long and up to 5 m wide, which is about the size of a backyard pool. You can only do a few swimming strokes at a time, but it is big enough to move around in. There is a rail on two sides that you can use to do some stretching. There are some limitations on the use of this pool because it is so hot: you can only use it for a maximum of 15 minutes at a time and you cannot use this pool if you are under 18, pregnant, have a heart condition or have been drinking. You also cannot put your head under the water. There is a hoist and ramp available for the elderly and disabled.
