Convenient do you won't have to sit in the bathtub.
The seat of the tub is amply sized. I have a big rear end and I fit on this just fine. I think the water stream is positioned more to the front, so you just need to position your body to get it into the right place where you need the stream to flow. I think the water stream pumps up high enough with the hand pump used in a free hand. It fits on my elongated toilet eat, and I assume on a standard as well. It will also sit directly on the toilet bowl. I like that it can fold up and become more compact. The ad/order page actually shows 3 different styles of this sitz tub (you can see 3 different hole patterns in the back of the seat). I received the one with 5 circle holes... I am sure they all function the same, but I don't know why the would depict them differently in this one order page. I removed a star based on this product depiction "sloppiness."  I do not understand what they mean by "no need to squat down."
