I'm wanting to finish my basement with a toilet, sink and shower. The problem is that my basement doesn't have a rough-in. Any guidance on how I could make this happen would be greatly appreciated. Thank you.

Hi Darren,
The hardest part about installing a bathroom in a "add on remodel job" is the drainage and venting. The floor has to be jackhammered up and the sewer main located. Then after you branch off the main you have to jackhammer the cement up and trench to pick up each fixture. Water will also have to connected and laid in the trenches to supply the fixtures. Once the floor's up and the trenches dug here's what will happen. Toilet connects to sewer main. Lavatory connects to toilet drain and runs a vent off the top the stubout tee out the roof or revents back into a dry vent in the attic.. The toilet wet vents through the lavatory vent and the shower connects to the lavatory drain and is wet vented by it. This is a normal rough in and is acceptable both by local and state codes and also The Standard Plumbing Code Book in 90 percent of the country. Check your local codes to make sure you're not in the excluded 10 percent.. The vent off the lavatory may be run out the roof or revented back into a dry vent in the attic or if you're reventing back into a fixtures dry vent you must make your connection at least 6 inches over that fixtures flood rim. Then the basement floor will have to be patched and tiled over to hide the patches. I hope I've given you a little clearer picture of what's involved and thank you for rating my reply. Tom
