A DIY bathroom remodel is a big project. If you can only work weekends, your bathroom will be out of commission for two months or more. You’ll need all your expertise as an experienced do-it-yourselfer because you’ll have to tackle electrical, plumbing, tiling, drywalling, taping and even exterior siding. In this DIY shower remodel article, we’ll deal mostly with the nuts and bolts of ripping out existing plumbing and replacing it correctly with new, easily installed PVC piping.

Bathrooms should always be functional before all else, so if you’re considering reworking the layout, keep functionality in mind. Make sure there’s enough clearance for the shower door and cabinet doors, don’t place a toilet next to a tub if you can avoid it, make sure there’s a place for a toilet paper holder near the toilet, and don’t forget about electrical outlets near the counter.


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).


Adequate lighting is needed for all forms of grooming. Include task-specific and ambient, or general, light. Multiple recessed ceiling fixtures are all but invisible and eliminate the locker-room look of a single ceiling-mounted fixture. Include a light fixture above the tub and/or in the shower. Avoid fluorescent lights, which alter the color of your complexion.
Turn off the main water supply to the house, and in a convenient location, cut the hot and cold water supply pipes for the bathroom. Also cut out and remove all the existing water lines and fittings in the bathroom. Finally, cut out and remove the vent section leading to the sink and the main stack 5 in. below the vent tee. Stuff rags into open drain lines to keep sewer gas out of the house.
This story shows you how to make your small, cramped bathroom more convenient, elegant and easy to clean. These projects make the typical 6 x 8 ft. bathroom feel larger and more comfortable. We'll walk you through the steps for getting more natural light in your shower, replacing your dingy old bathtub with a spacious shower, and installing a toilet and sink that simplify cleaning. So stop dealing with an outdated bathroom and get to work!
Low-flow toilets, which use 1.6 gallons of water per flush, are required by law in all new and remodeled baths. Pressure-assisted toilets effectively clear the bowl with one flush, but make considerable noise in the process. Gravity models sometimes require two flushes to clean the bowl properly. For maximum efficiency, choose a bowl with a large water surface. Make sure there's sufficient space around the toilet for comfortable access—ideally, at least 16 inches from the centerline of the toilet and walls or fixtures on either side. Also allow at least 30 inches from the front of the toilet to the nearest object.
For your remodeled bathroom to operate well, it’s critical to install vent and drain lines of the proper size and slope. Use a 2-in. line to drain the shower and 1-1/2-in. line to drain the sink. The vents for the sink and shower can be 1-1/2-in. pipes, but a toilet should be vented with at least 2-in. material. Make sure that the drain lines drop 1/4 in. for every foot of travel toward the main stack.

After removing your shower head and handle, cover your shower floor with newspaper. Take your hammer and chisel and start from the bottom corner. Gently place the chisel on the side of tile and use your hammer to push the tile out. Start gently. As you move on, you may have to use some real elbow grease to get these tiles out. Once all tile has been removed, chisel off any remaining mortar as well.


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.
The key to a weatherproof, attractive glass block window both inside and out is to encase it in a custom-built wooden frame (Fig. A) with inside dimensions that are 1/2 in. taller and wider than the panel itself. That will give you room to adjust and shim the panel exactly and then inject expanding foam between the frame and the panel to lock it into the opening (Photos 3 and 4).
