If you must do this, Scootaloo maybe sit in the bathtub next time. You will still get the warmth you want without leaving a a puddle on the floor.
 
Then, you can open up the drain and watch (and listen to) the “water” drain out of the tub. Next, you can rinse yourself off with the water, stomp on the overalls with your hooves to wring them out and either hang them up to dry or put them in a hamper to wash with the rest of the laundry.
 
That should work reasonably well. After all, the Romans used to wash their clothes with urine, stamping, and a large quantity of water (not necessarily in that order).

Just enjoy the warmth and worry about the mopping later.

Can we get one with both please?
