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 full bath requires a minimum of 36 to 40 sq. ft. The finished room must measure at least 5 ft. in one direction to accommodate a tub. Building codes typically require 32x32 in. (finished dimensions) for a shower; if you have the space, larger is better. Just make sure the shower is large enough so you can comfortably raise your arms and bend over in the space.
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).
Adding a soaker tub or multi-head shower? You may need a bigger water heater. Tank-style heaters are labeled with a first hour rating (FHR), a measure of how much hot water it produces in an hour. To help determine your FHR, use the list below to calculate your family's hot-water consumption in the bath each morning. Visit the U.S. Department of Energy for more info on FHR.
Don't settle for a wimpy flusher. Maximum Performance testing (MaP) gauges a toilet's ability to get the job done with just one push of the handle. Look for a loo with a MaP score of 500 or higher; this group includes many WaterSense-rated toilets, high-efficiency models that use as little as half of the 1.6-gallon-per-flush legal limit.

An upscale bathroom remodel may include structural changes like expanding or adjusting the layout. Finishes include things like large ceramic floor tile, heated floors, high-end faucets, new lighting, and stone countertops with double sinks. Showers may have frameless glass doors, rain shower fixtures, shower niches and tiled shower walls. Freestanding tubs are also found in this type of bathroom remodel.
