My parents got one of these for their old house, for a brief time when my grandma was living with them.

10/10 recommended. You can sit and let the hot water wash over you, or take a few minutes after a regular shower to enjoy the steam and warmth on a cold winter day.

Just make sure to move it around (and, obviously, clean it) periodically so the bottom of it doesn't end up making scum/mold spots on the shower floor.
