One of the best features of whirlpool tubs is that the pump isn’t going to be sticking out. It’s usually hidden behind the side panels of your tub, so it’ll never be in view when you’re in the bathroom. That means you don’t have to set any extra space aside to make room for the pump. But what you will want to do is make sure that you’re sizing the tub you buy correctly. Make sure you’re leaving extra space around the tub so that you can get in and out without knocking into things. It’s usually better to go a little smaller and have extra floor space than go larger and make your bathroom feel cramped.
