Step 8: Install Sink, Faucet, Shower Head and Toilet
Reinstall the toilet using a new wax seal.
If you had to cut any part of the wall to make the sink fit now is the time to fix that with new drywall where it was damaged.
If you don't have experience with any plumbing you could hire a plumber in install shower and sink fixtures. I did it myself. Follow instructions to avoid any leaks. Again, not something you want in a reno project.
Tip - Take a picture of the pvc pipe before you remove it. That way you can reconstruct it after and avoid purchasing new. You will need to clean it very well. It will be massively gunked.
