I was shopping for a 24 inch vanity to replace my temporary vanity (plastic). I noticed the drain pipe is 16 inches from the tile floor. The bottom of the trap in the photo is about 10 inches from the tile floor.
Because the trap is so close to the floor, I would have to avoid any vanity with a drawer on the bottom it seems and go with a vanity with two large doors (white vanities). The drawer on the bottom seems useful but I don't think there is enough room between the trap and the floor (grey vanity)
