This weekend a friend of the family installed a new tub for us and put new backboard around it. Unfortunately, he didn't do the greatest job with it and now I need to know how to fix it!
The backboard sticks out from the wall 1/4" at the top (which it always did) and continues down straight until about a foot from the top of the tub. At which point it rapidly tapers down to nothing!
We need a relatively flat surface for tileing, and also to make it look finished. My do I add an extra 1/4" thickness to the area? It has to be able to hold up ceramic tiles
Any help???
