Rated 4.0 out of 5.0 by Good for First-timers Having never laid a shower pan before and with very little deck mud experience, I opted to spring for the Pre-Pitch and Quick Pitch systems. They definitely made the process much easier & I'm confident improved my end result. The system is very easy to use & there are great videos on the company’s website that detail how the product should be installed. Once you’ve measured and cut your float sticks (I used a circular saw to cut mine but they’re just PVC, so they’re pretty easy to cut), they press into the ring & sit over your drain & you just fill one cell at a time, screeding the deck mud until it’s even with the top of the sticks. It’s important to note that because it sits over the drain screws, it adds an additional ¼ of an inch to the height of the shower base. Initially, I was judging where the shower floor would line up off the height of the sticks, but it ended up being slightly higher (not a big deal unless you’re pushing the minimum 2” interior curb height above your drain). My only complaint is that most showers, if done as they suggest, will require 8 sticks and they only give you 6. I feel like at this price, the customer deserves a full 8 sticks without having to purchase an add-on. With that said, I didn’t purchase additional sticks and still made it work. It was a little trickier in the two wider cells, but nothing too bad. All in all, it’s a major timesaver & it’s easy to use. I definitely recommend both the Pre Pitch & the Quick Pitch to anyone who’s even a little unsure about their ability to evenly lay a shower pan at the correct pitch. August 14, 2013
Rated 4.0 out of 5.0 by Well thought out product After 30 years of installing shower pans it took me a couple tries at this product before it sold me. I can use this with any drain, but I do have a preferred chrome drain that is thinner than most of the cheaper plastic drains that most plumbers leave me. The best part of this pitch kit is the opening that is left at the drain that allows the secondary drain holes at the liner clamp to be open and free of concrete or pea gravel that usually would hamper the draining of water that soaks past the grout.

Rated 5.0 out of 5.0 by Product was easy to use I have a variety of previous experience doing home remodel and repair, however this was the first time doing a shower pan. I used the Goof Proof slope sticks to help define a smooth, even, surface for the shower floor, prior to tile. The slope sticks worked out really well!!! April 8, 2014
Rated 5.0 out of 5.0 by Excellant Product I've been in the tile trade for 30+ years and still enjoy the ease of this product to do quick slopes for custom made shower pans. You may wish to obtain 2 extra sticks so you can get a complete "asteric" on the floor. February 14, 2013
Rated 5.0 out of 5.0 by A must for custom showers I have used this product many times and will continue to use it as it make the job a lot easier and gives you a finished product that the customer loves. April 30, 2013
Rated 5.0 out of 5.0 by No brainer I'm a wannabe remodeler. I'm remodeling my seventh house and this was my third custom shower. Piece of cake. Make sure whatever model drain and its associated drain flange you use is good and level and the top of the flange is at or near your rough floor height, glued in and set with a level mortar/bedding sand mix base, etc. Set the goof proof ring on the flange bolts and follow the rest of the easy directions. My only complaint is I wish the kit came with eight sticks instead of six to make troweling in the bedding sand mix a little easier between the sticks. March 27, 2015
Rated 2.0 out of 5.0 by Good quality not right for my install. Returned This product seem good to use after using the pre pitch system which worked great, but the drain did not want sit low enough and it would have made my shower slope really high towards my step in part of the shower. This is why I returned. If ring was about half the size it probably would have been a perfect product June 24, 2015
Rated 4.0 out of 5.0 by Saved my Bacon 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 final slope for 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). And to this point I have both a complaint (just voiced) and a rave. I completed pouring the floor late on a Sunday: late enough that the final batch of mix was done in the dark. You know how it goes when you're in a hurry -- not so well. And in this case I wound up with a low spot in between widely spaced rails that I didn't notice for 24 hours. Some online research indicated that the only correct fix is to remove the concrete and re-pour. That turned out to be easy, and because the quick-pitch defines a clean zone, it was easy to re-pour and get the slope right. I have a friend who, after two attempts (literally two floors poured on top of each other), still has a low spot. He poured without this aid. February 28, 2012
