Follow Fig. B, for the new drain/vent plan. The new shower drain is vented separately into the main stack (Photos 10, 12 and 13). Most bathrooms have the main stack positioned directly behind the toilet. The wall-mounted toilet shown here cannot be positioned directly behind the stack because there’s not room for the necessary elbows. If your stack is more than 12 in. to the side of the existing toilet, you can keep the same location for the wall-hung toilet. But if it’s directly behind it, you’ll need to swap the sink and toilet locations like we did.
To begin, rip the top and side jambs to the thickness of the wall framing plus the exterior wall sheathing. The cement board will lap over the jambs. The windowsill should also be flush with the interior framing, but hang over the outside sheathing about 1-1/2 in. and have a 5-degree slope toward the outside to help shed water. To keep water from running behind the siding as it drips off the edge, cut a shallow groove (or saw kerf) in the bottom lip (Fig. A). Also, remember to flash behind the trim to keep the window watertight. Trim the window exterior to match the house, using caulk to seal between the trim and siding.
The average bathroom remodel costs $10,445 Most homeowners spend between $5,975 and $14,927. You can spend as little as $3,500 to $7,000 updating the essentials in a small or medium-sized bathroom. On a large or master bath, you could spend $25,000 or more. Labor averages 50 percent of the total project price at about $65 per hour. Expect pricing to vary regionally up to 20 percent due mainly to labor. Material prices stay roughly the same across the country.
Tear out the existing piping (Photos 5 and 6). Then frame the 2×6 walls that will contain the new plumbing and the opposite end of the shower base (Photos 8, 9 and 14). It’s easiest to nail the bottom plate to the floor and the top plate to the ceiling, then fill in the studs one at a time by toenailing them in at the top and bottom. Stack the studs directly in front of the old ones wherever possible. Space the studs in the center of the shower about 12 in. apart to leave room for the shower valve and showerhead. The studs behind the toilet should be spaced exactly 19-3/4 in. apart for securing this toilet chair carrier (Photos 8 and 15).

Wall and Floor Tile: Ceramic, porcelain and natural stone are popular picks for floor tile in bathrooms. Materials will be the deciding factor here, but natural stone often costs more to install because it is difficult to cut and place. From natural stone and classic ceramic to glass and mosaic styles that mimic natural materials, wall tile options vary.
