We are finishing our basement. Our home is 110 years old. The basement used to be dirt floor but in the 40's it got concreted. At some point a water closet existed because there is a toilet drain and sink drain and vent. We want to add a clawfoot tub a urinal, sink and toilet.There is no drain for the tub. I realize the floor will have to be cut to add the drain.

Here is a photo of the sink drain/vent tree. I am wondering if I can tie the urinal into this tree as well as the sink?

Here is a photo of the toilet drain.

Would I cut the floor and tie the Tub drain into this drain? I don't know if the toilet uses the same vent as the sink did.

Another photo of a line in the floor that was capped off.

I wonder if it is a vent. I have put the garden hose in it and can see water running through the clean-out in the basement.

Or I could run my tub drain to the line that drains the upstairs bathroom and laundry room(below)

Any and all suggestions are welcomed. I am a fairly adept DIYer however I'm inexperienced with this type of plumbing.

Looks to me like you need a plumber to come to your house and help sort this out.

Hi all...

Pretty sure we can figure this out... ;)

Drew... check which plumbing code prevails in your area and let us know... OK?

Also, see if you can remove/cut off the cap and let us know what you find under it. Be sure to plug it off as we work through this.

Back to you...
