We bought this to fit within an 18" cabinet space, and it fits perfectly. I bought it because it was the only one at this price point that had a drying feature, whereas dishwashers of the same size at this price point from the other brands did not seem to have heat drying. The drying feature works rather well, but you will still find some water resting on top of the glasses, etc. I think this is rather normal, in my experience anyway, and we just leave the dishwasher open for a bit before unloading to let them air out.

The instructions say that it needs at least 2" clearance from the wall, but ours is installed right against the wall (about 1/8" clearance) and it opens just fine. [This review was collected as part of a promotion.]
