Hi everyone. I'm at my parents and my dad said he would help me make a new rack out of some melamine he has sitting around. My problem is i dont have a tub here to use as a spacer while building it. so i was wondering if anyone had the exact height measurement of the tub?, or if anyone uses one of these racks yourself without the lids how high is the space for the tub? I would appreciate it alot if someone could help me out with a quick response
