They look great and are well made but i was forced to raise my floor about 4 inches to accommodate their height. My sub floor is wood so if you include the baseplate, shower pan liner and then this shower drain you are forced to raise the floor so that the tile ends up being flush. My original plan was to have the entire floor all one level. If your subfloor is concrete you can just dig out the depth you need and you would then be able to make the floor all one level including this shower drain. The other option with a wooden subfloor which i did not or could not do was lower the shower area of the subfloor but it would have interfered with the floor joists as this is a second floor. All in all in came out great and I have no complaints.
