This threshold goes perfectly with my new bath tile floor, and has unique dimensions to fit. The floor was raised for a walk in shower. This threshold makes up the 5/8" height difference perfectly! One additional comment, when I called to ask for the thickness of the edge on the saddle side I was told 3/8" which is normal. However, it's 3/16" on the saddle and 13/16" on the other which makes the fit perfect!
