Rated 5.0 out of 5.0 by Super time saver for custom shower pans Okay, for this project we decided that most prefab shower pans are too boring. But on top of that, they seem super expensive considering the materials they are made from and the manufacturing casting process. Anyway we decided to match the curve of the curb side to the curve of our (you guessed it) curved shower curtain rod. Pre-Pitch allowed us to keep the mud pan thin so that the build up to the main floor was minimal. The Pre-Pitch extensions allowed us to run the pan area out 5ft. Probably the only elegant solution at this price point. Shipping was quick from Home Depot, so there was little delay. March 20, 2012
Rated 5.0 out of 5.0 by Made this project so much. Easier!! So glad I bought this and you will be too. I had no idea how to pitch my shower pan and to think about the math to figure it out was driving me crazy. So I ought this instead and it literally was plug and play. October 31, 2014
Rated 4.0 out of 5.0 by Does what it promises -- very well I'd heard about these online, but was unable to find locally (Seattle area) -- not even at Home Depot. Allowed me to easily set the slope for pre-pitch in my shower. Note that you need both pre-pitch and quick-pitch for a complete solution: this was not clear in the write-ups that I found online. My two complaints: (a) very expensive for a few hunks of plastic, and (b) could do with at least 2 more angled rails (they ship 6, really needs 8). February 28, 2012
Rated 2.0 out of 5.0 by Excellent idea but poor engineering, execution and instructions. Excellent idea but poor engineering, execution and instructions. Only 11 screws are provided for 6 strips? The screw hole spacing on each strip is on 3" centers. Which 2 holes or hole do you put screws in? Even if just using 2 screws per strip, you would still need 12 screws and that isn't nearly enough to keep the strips from wiggling. Step 6 of the instructions tells you to "be sure screws or nails are counter sunk so they do not puncture the liner." Nails? What nails? At any rate if you use the screws provided to secure the holes nearest the drain, you soon discover the plastic strips break into two pieces before the heads of the screws are flush! The screws provided are of the countersink variety, and are not square shouldered. The countersink acts like a wedge against the square shouldered holes in the plastic and causes the plastic to split apart. Ouch! July 1, 2012
Rated 4.0 out of 5.0 by Good quality, simple to use, good results! I thought one more set of shims would have been helpful, but all in all, this is a good product. My floor was concrete, and rougher than most, so the mounting tape option wouldn't work, Hot melt glue was the ticket. May 7, 2013
