When installing a shower tub, it is vital to accurately install the shower tub plumbing to ensure proper functionality. With light plumbing knowledge, you can install a shower tub and complete the plumbing aspect of this project without the need for hiring a professional. Even if the location of your new shower does not have the plumbing in place, you can tie into your existing plumbing pipes and add a shower tub into any location you desire. 

Step 1 – Shut Off Water 

Before you begin any plumbing work, you should first shut off the water to your home. Access the main water shut off valve to the home and turn off the water. As well, open a faucet in a sink allowing the excess water in the pipes to drain before proceeding.

Step 2 – Access Plumbing Pipes

You will need to gain access to the existing plumbing pipes in the floor and walls. You may have to remove flooring and drywall to access these pipes. Once you have exposed the pipes, locate the hot and cold water pipes. 

Step 3 – Cut and Measure Pipes 

You now need to use the hacksaw to cut into the hot and cold water pipes. Then, use the file to smooth the edges of pipe where you made the cut. Measure and cut the plastic pipe to fit the length required to run the plastic piping from the previously made cut to where the hot and cold faucet will be. This pipe will carry the water from the hot and cold pipes through your faucet and into your tub shower. 

Step 4 – Connect Pipe 

Apply the pipe cement to the hot water pipe generously and connect a pipe fitting over the solvent. Repeat this step for the cold water pipe. Now connect the plastic pipe to the hot and cold water pipe through the fittings and run the pipe in the wall and between the studs to the faucet locations. Avoid running the pipe horizontally in this process. Once the pipe has reached the desired location of the faucets, you can test the pipe for leaks. Place a cap at the end of each pipe and restore the water to your home. Thoroughly inspect the new pipe and fittings for leaks and seal any leaks detected before proceeding. Be sure to remove the caps after completing your test and to shut the water off before proceeding. 

Step 4 - Connect Faucet 

When you are at the point in your shower installation process to connect the faucets to the pipes, be sure to follow the manufacturer’s instruction. Varying faucets require different installation steps and techniques that should be explained and outlined within the instructions. At this point, you can connect the shower riser to the faucet and run this to the desired location of the showerhead. The showerhead can then be attached to the riser. As with the faucet, be sure to follow any instructions included with the riser and showerhead.
