Walk In Baths

Do all the water out when you go? Please explain ....

It looks like an appointment in the box and the bather sits on a seat is widely used in homes for the elderly.
Undressed person walks in and sits down.
A door fell into the front and there is a device that inflates snap joints (I think they are probably rubber).
The water is then executed in the bath.
When finished, remove the plug to empty.
Press the button that releases the seal and swimmers can escape.

water can not get hot, so you're sitting on the seat and water is left in the bath at the right temperature

No, you walk in the door, close it to form a seal, then run water in.

Allow the water to open the door and leave.

I do not want one of these - my bath water is still too hot to begin, I'd end up with third degree burns or something!

HA HA, I bet quite a few have thought the same thing ...
