I want to install bypass shower doors on my existing tub but on one side of the end wall it has about a 7 inch tile built out so my tub height is about 3/4 in. lower than this 7in. Tile that extends out from the wall. I really don't want to cut into the tile. What would I use to raise up the lower track 3/4 - 1in. So that it can be mounted to both end walls and be level?
