Toenail 2×6 blocks in the center of the shower 36 in. above the floor for the shower valve and 6 ft. 6 in. above the floor for the showerhead. Position the valve block so the plastic mud guard on the mixing valve will be flush with the finished wall surface. Attach the shower supply line and the hot and cold supply lines to the valve. Clamp the valve body and shower supply line to the blocks with copper pipe straps. Run copper water supplies to the new locations for the sink and toilet.
A DIY bathroom makeover is not complete without new floor tiles. But before you start grinding away with the grouting, use a mason’s chalk line to mark reference lines perpendicular (at a 90-degree angle) to the wall with the longest continuous line. This will allow you to keep your tiles in a straight line, avoiding the dreaded crooked tiling job.
