The Innovis Ledgeline floating shower shelf is 36" in length and 3.5" deep. It is as simple as marking the placement and holes on your cement board, drilling the holes and mounting it on the wall. Once it is mounted, there is no wait time, you are able to tile it right away.
The Ledgeline shower shelf can be cut down to shorter than 36" length or you can use multiple pieces to make a shelf along your entire wall. This shelf can also be used anywhere you want a shelf to go - in your kitchen tile back splash, your bathroom back splash above the vanity or behind the toilet.
