I purchased this tub filler and I have to say it's awesome. The water flow is excellent along with a nice valve that allows you to switch from hot to cold. The installation was straight forward. the plumber did the install but I looked over his shoulders. The box that connects the hot and cold is mounted to the floor joists then the tile added on top. When it came to adding the filler it slips into the top of the box and the connection is made. Great product but also the folks that sell the product are awesome.
