Once you have identified the correct pipes, it will save your time and hassle of shoveling through the floor aimlessly.

Otherwise, you will have to get a pipe outside.
Step Four: Find the Drain Pipe
Next, you have to trench the floor to find the drain pipes to connect them with your shower or toilet. Basement slabs are generally thin; you will have to take out large concrete chunks along the marked trench lines. You must make the trench lines wide enough, so it helps in connecting the pipes. Once you have exposed the drain lines, you need to hook them up.

Step Six: Make a Slope
This step is the most crucial one for plumbing for the basement bathroom. You need to maintain the slope while working on the branching of pipes. The slope should be around 1/4 inch per foot in size. You can check the slope with the help of a torpedo level. Once you have set up the slope on the pipe, fill it with dirt to ensure it doesn’t move.
Step Seven: Wrap It All!
Fill up the area that you excavated. Mix up your gravel with concrete and patch it up. Ensure that it is leveled. Cover and wrap up the work after setting up pipes.
