My husband saw that one but I was not sure how sturdy it!I am not sure how heavy duty a tub you are looking for, but I love my Booster Bath! I have had it over four years now and it is great. No way I could get down on my knees to bathe them in a regular tub.
They are under 200.00 most everywhere, and I got mine off Ebay with free shipping....
It is a heavy duty plastic, easy to assemble and lightweight so it is easy to move around.
