Over the years of building shower curbs, we have found that the easiest product to build a gorgeous looking and durable shower curb are the Curbsill Thresholds. These thresholds provide an efficient seal for shower doors. You can also use this for any glass door or wall and get a smooth straight ledge. 

There a wide choice of colors available including Black, Bone, Cashmere, Lite Fawn, Tidal Sand, Walnut Toffee, White, and Whole Wheat. Recently, we have added a new color, Pewter, to our cultured granite choices. Check out our matching three tier corner caddie, or need a matching or coordinating bench or shelf slab? Explore the color and finish options of our curbsills; guaranteed to coordinate and match your shower and bathroom design. Not sure which color will match? Order a sample!

There are a variety of lengths to choose from: 24″, 30″, 36″, 48″ and 60″. Or if you need something custom, contact us for a special order quote.
