Rated 4.0 out of 5.0 by very helpful form tool worked great to help form the curb to the right shape consistently. It is a bit brittle, so when my 7 year old stepped on the plastic frame work, it cracked in a few spots. didn't affect the performance though. December 30, 2014
Rated 5.0 out of 5.0 by Kirb-Perfect shower curb building Kit This thing was a life saver. I am not experienced in using concrete and was afraid to tackle doing the shower dam until I saw the curb building kit. My curb is perfect, strong, the right angle and easy to use. December 9, 2014
Rated 3.0 out of 5.0 by Good guide It was a good guide, but I had to modify for my installation. This was made for a 32" shower curb, but I had a 36" curb. I didn't notice the length in the description. I wanted a lower curb for a more handicap friendly installation, so I had to cut away at the bottom of each rail to get the lower height. They didn't have screw holes on the top and sides to hold down the assembly. I used screws that were self drilling to accomplish my goal. When installing the mortar, it worked very well. It was a great guide to get an even layer of mortar, as well it helped support the mortar. Because of this, I would buy again, and recommend it. September 30, 2014
Rated 3.0 out of 5.0 by Does ok if you are handy The concept is an excellent idea, the product needs a little work. It was really expensive and it required 2 kits to make it long enough. 30" is not enough for any curbed shower that I can think of. The two kits are suppossed to be able to be attached together, kind of like a puzzle piece. The problem was they didn't fit into each other. I had to shave down the inside piece, all four of them, to be able to get it to work. It also says that there are arrows on top to point to which side is in the shower so that the curb is slanted down to the shower for runoff. This is kind of a moot point though as you have to cut the inside down anyway after the prepitch and then level it out anyway when you pack it with mortar and do the second mortar bed. It was a selling point for me but didn't help at all. you could really have it face either direction and have to fiddle with it just as much to get it right. Other than that, it looks really good, is nice and square and solid once I got the mortar packed in their. It is a little bit more difficult than the video shows you as you have to pack each one of those little rectangles on all three sides with mortar. THe video appeared to have mortar that was too thin for proper mortar mixture. August 4, 2014
Rated 5.0 out of 5.0 by Easy way I have found. Was simple to put together and to use. If you are looking for an easy way to make a curb then this is the answer. September 30, 2014
