“benefits of glass is the look is light-and-bright, airy – as with other surfaces, glass kitchen countertops can be custom-designed…without seams, with a contemporary finish, or used as an accent, such as a raised breakfast bar on an island.”

If you are searching for a more streamlined and contemporary look for your new bathroom tile floor, there is a solution. To get away from a threshold and copper insert, you can use a Laticrete product that is installed flush with the existing floor so that the tile is all on one level with a built-in pitch so the water can drain properly. It gives you a nice clean look without boxy thresholds to trip on.
