Product review (5 stars): Perfect for my dishwasher space, on a 2nd floor over plywood.
Worked well for my dishwasher space. Although I had to trim all around the top lip with a Dremel to get it to fit snug. I installed new laminate flooring underneath and throughout the kitchen. So on the edges where this sits on top, was foam backer rod with 100% silicone sealant. I had to shorten the legs of my dishwasher (just turn it like a screw). Went in there nice and snug. I'm happy with this, everything turned out perfect.

Other reviewers disliked that this doesn't have a front lip. I also questioned that at first too, but after installing it with my dishwasher, I see why it's designed this way. My dishwasher has a bottom front metal skirt that adjusts with the height of the legs. It's detachable to help slide the dishwasher out. A front lip on this pan would have made it impossible for me to slide the dishwasher in.
