Step 1
Design the layout for your bathroom and obtain any necessary building code specifications and permits.
-
Step 2
Determine the size of pipe used for your water supply, usually from 1" to 1½ " in diameter and for your drain system, which is typically from 1¼" to 4" in diameter. The PVC and drainpipe you use should match the existing pipe in your home. Also try and determine what types of fittings and connectors you will need. A little forethought will save trips to the hardware store.
-
Step 3
Measure the distance from the sink stub-in to the placement of your sink. Cut a length of the appropriate PVC pipe to fit and determine if any connectors are necessary. Connect the pipe to the stub-in by first applying PVC primer around the outside of the stub-in pipe and around the inside of the piece to be joined. Apply the cement over the primer and quickly join the pieces using a slight twist. Hold in place for about 30 seconds.
-
Step 4
Follow the same guidelines for running the water supply to the shower/tub and to the toilet. Measure, cut the pipe to fit, attach using the connectors, primer and cement.
-
Step 5
Mark the placement of the toilet and position the toilet flange by cutting a hole for it through the sub floor with a jigsaw. Center it 12 inches out from the finished wall. Anchor the flange using screws at the finished floor height.
-
Step 6
Dry-fit the drain line to determine the fittings and pipe lengths for both the sink and shower/tub. Once your placement is correct, disassemble it and connect it using the PVC primer and cement. Drainpipes should be sloped a quarter inch and supported every 32 inches.
-
Step 7
Run the drainpipes to the tub and the sink using the PVC pipe and methods described earlier. You are now ready to install your fixtures.
