Few things compare to the excitement of getting a new bathroom complete with the layout and fixtures that you want, whether it’s adding a new bathroom in the basement for added convenience or finally granting your spouse’s wish to add a bathroom in the master bedroom. However, to do so requires installing new pipes in your bathroom.

To plumb a bathroom does not always require a professional plumber. In fact, you can plumb your bathroom yourself using the following eight essential steps on how to plumb a bathroom.

1. Establish Where You Want the Bathroom Fixtures to be Positioned

The first step how to plumb a bathroom is to establish where the shower, the sink, the toilet, and bathtub will go, which will help you determine where you need to run the plumbing lines.

2. Cut Openings in the Floor

Carefully measure all cut outpoints and drill points, and then mark these points so that you know where to cut and drill.

Next, complete all the cutting and drilling where indicated in order to prep the floor for installation.

3. Shut off the Water to the Bathroom

Locate the bathroom water valves and then shut them off. This will enable you to perform your plumbing work in dry conditions.

4. Run the Hot and Cold Water Lines

There will need to be a total of 5 water lines installed in a standard bathroom, which includes a cold water line for the toilet and a cold and hot water line for the sink, the bathtub, and the shower. You will also need to use flexible lines from the cold and hot water lines to the bathtub and sink faucets.

The water lines are usually installed under the floor; however, they can also be run through the walls, depending on your needs.

Once the water lines are properly installed, if you are using copper pipes as opposed to tubing, smooth the pipes, using sandpaper, and then connect the pipes by soldering them to the main water lines.

5. Attach the Drain Lines

You will need a 1 1/2-inch drain line for the sink. For the toilet, you will need between a 3 to 4-inch line, and for the bathtub, you will need a 2-inch drain line.

When installing the pipe to the toilet drain, be sure it is aiming downward toward the main drain line.

6. Install the Toilet Bowl

Attach the flat rim of the nearest waste pipe to your bowl. Use an adhesive to hold the rim of the pipe in place so that the slot lines align with the bolt slots on the toilet.

Next, align the toilet over the bolts and the rim of the water pipes. To ensure the toilet is position correctly, simply sit on the toilet and then maneuver it to and fro.

Once the bowl is in place, secure the bolts and the washers.

Lastly, using nuts, attach the toilet’s tank to the bowl. Attach the water line, and then caulk around the base of the bowl to secure the toilet.

7. Install the Sink

Next, we’ll be plumbing the sink. Place the base of the sink into position.

Make and indication where the floor bolt should go, and then drill a hole through the sink base to attach it to the floor with a nut and bolt.

Attach the sink to the cold water and hot water lines. Next, install the handles, the stopper, and the drain to the top of the sink.

Place the sink on top of the base, and then use adhesive to secure the adapter and threads to the drain pipe.

8. Install the Tub and Hook up the Shower Unit

Make an indication on the floor to determine where the drain will go. Next, run the drain line, and then align it.

Once the drain line is properly aligned, use adhesive to secure the drain line to the drain on the tub.

Position the tub in place, and then be sure it is even.

Maintaining Your Bathroom

At some point, the fixtures in your bathroom may become clogged due to a build-up of debris, such as hair, grease, and soap scum. If left unattended, a clog can cause pressure to build inside the pipes, which could cause them to crack or burst. Therefore, it is important to address clogs as soon as possible to avoid costly repairs later.

To de-clog your pipes, simply begin by pouring boiling water into the drain, which can often be used to liquefy organic matter.

You should also be sure to keep a plunger on hand to de-clog your fixtures in the event that the boiling hot water does not work.

To plunge the sink, fill the sink half full with water, and then place a cup-shaped handheld or full-length plunger over the drain. Next, press down slowly to create suction, and then firmly lift the plunger to clear the drain.

To plunge a clogged toilet, place a toilet plunger, which also has a cup like a sink plunger but also has a soft-rubber flap that folds from the inner part of the cup, over the toilet drain, and then press down slowly to create suction, then lift the plunger firmly to clear the drain.

You may also want to invest in a drain snake, also known as an auger, for more serious clogs, which feeds a long, flexible cable with a cone-shaped coil on the end into the pipes to attach or flush the clog.

Use chemical drain cleaners sparingly as they may damage the pipes over time.

To help keep your drains clear, cover the drains with strainers to catch hair and other objects and prevent them from entering the pipes, and run hot water down the drain following each use to rinse away fresh build up.
