we always brought all our Ts into the shower with us. they loooooooooooove the higher humidity!
no you don't take them into the stall... just set them on the counter and then when you leave the bathroom keep the door closed so the temp and humidity lower slowly (so it's not a shock for them)... after about an hour i'd go in and return each enclosure to it's original 'spot'
hope that assists ya.
