It's 175 gallons. Like 12 people can fit in it ???
It has to be 98-100 degrees. To cold and baby will breathe underwater, to hot and it can cause problems from mom and baby overheating.
The tub is a hard plastic outside with foam on the inside and a plastic liner that goes over that and then another liner that's disposable goes over that. There are heaters that go into the first liner and keep the water at temp. It won't heat it, but it will keep it at 100 degrees.
Yours looks fancy! Mind was just a blow up tub but I loved it still! Mine was in my living room :)
