    • Concrete-feel, prefab curb that speeds up shower builds
Style: 38 Inch Shower Curb
Review Image by Margot B Margot B

Short version: this JIANBENKJ 38" shower curb does the job faster than building a mud curb. It feels like concrete thanks to the cementitious shell, and will make waterproofing between floor and shower more straightforward. Compared with a Schluter Kerdi-Board curb, it’s cheaper. * Shell feels like fiber-cement; core is XPS foam with fiberglass mesh—light to carry (about 7 lb) and solid to the touch. * Per my measurements (see photos), 5 3/4" x 4.5" x 38 1/16" (slightly different than stated dimensions of: 38" L × 6" W × 4.5" H) Trade-offs: the top isn’t pre-pitched; add a slight inward slope (about 1⁄8" per foot) with thinset when you set tile. Because the core is foam, through-fastening (screws for glass clamps, etc.) is a potential leak path, so be sure to fully seal penetrations. Value & who it’s for: at about $50, it’s a time-saver for DIYers and pros who want predictable geometry without mixing mud or cutting block. In my case the curb is for water retention in an open entry/walk in shower plan, so I don't plan to add any hardware to the curb itself. If you need a ready-to-tile curb that’s trimmable and light, buy this. If you prefer the absolute rigidity of a masonry curb or plan to anchor heavy door clamps with screws, skip to a solid-surface base or mud curb. Disclosure & durability watch-list: I haven’t tested this over time, I will update the review once I've had some longer term experience with this item . NOTE: Per my measurements (see photos), 5 3/4" x 4.5" x 38 1/16" (slightly different than stated dimensions of: 38" L × 6" W × 4.5" H) ... show more

    • Great Quality Product - Great Value
Style: 38 Inch Shower Curb
I needed to install a shower curb for the walk-in shower, and I found this prefabricated waterproof shower curb. This is exactly what I needed to finish up this shower project. The product comes ready to install and ready to tile. The build of the curb is solid. The 38-inch38-inch height is perfect for stepping in and out of the shower. It is fabricated using layers of durable materials, including cement mortar, fiberglass cement mesh, another layer of cement mortar, and a layer of EPS (extruded polystyrene). The curb comes ready to cut, so it can be easily customized to fit your specific shower dimensions. Once tiled, this prefabricated curb is indistinguishable from a built-in one. Now, I can hang this heavy shower door properly. The curb is made to be sturdy and durable. After some use, I feel very confident about the structural integrity of this product. This is not something that will just fall apart. I have even stood on top of the curb with all of my body weight, and it felt extremely durable. The price point on this product is an excellent value for the cost. Comparing it to other prefabricated shower curbs, there are definitely savings to be had here. I highly recommend it for anyone doing some shower remodeling. ... show more

I ordered this as a way to contain water in my roll in shower, if the angle pitch ever fails. It is being in stalled near the front of the shower. It's really affordable, my tiler is installing it, and he says it's an easy installation. The quality is solid, and evident when you touch it. I included a copy of the installation instructions for DIY people to consider. ... show more

    • Good quality, fair price. Recommended.
Style: 38 Inch Shower Curb
Quality seems just as good as the name brands at a much more affordable and reasonable price. I've been installing ceramic tile for over 30 years, I use many different brand foam shower curbs, again this one seems as good as any of them. I don't expect that many problems with it at all. As long as you install and seal all the corners with waterproof membrane it'll be good to go. ... show more
