Finishing my basement, trying to figure out what each of these already installed plumbing fixtures are.

Submitted by THETRILOBSTER t3_zw8nkz in DIY

Here's a pic of what I'm dealing with: https://imgur.com/a/T2eAohA

Original homeowner said he had plumbing hookups installed in the concrete during the build but I'm not sure what each of these are. I assume based on the reading I've done and videos I've watched 2 and 3 are shower drain and toilet drain respectively but I'd feel better if someone confirmed. 1 and 4 I'm guessing are drainage hookups for sinks although I'm confused as to why there would be two.

Is it obvious what each of these are just based on the picture?

This whole area is stubbed out for a bathroom.

  1. vent stubout
  2. for shower drain.
  3. toilet ring
  4. sink drain stub out.

When you plumb in your sink, you will need to run its own vent. That will tie into the inwall drain.

Thanks alot for taking a look. First time taking on basement plumbing, the reading makes more sense when you can put it together with what you're looking at in your workspace. Appreciate it!

This would also be my guess.

Usually there's blueprints that come with the house with concepts of what could happen in the basement. That would also help confirm if you happen to have them.

That is what those are. I do construction.
The square box is framed out there won't be any concrete there once he takes off the tape. Find a 2"pvc pipe sticking up. That is where the shower drain will go. The ring on the floor, that is a toilet ring. Not getting away from that one. The way it is currently oriented the toilet can only go one of 2 ways. 90° opposite of the slides. The other two coming up, the #1 is too close to the shower to be the sink, it is also too small. That leaves it the vent. The last one sticking up, that one is far enough away to allow for a vanity. Thus a sink.

Um I have done a lot of basement bathrooms on newer houses that had all these "rough ins" That is what they are Rough ins for a bathroom.

Problem is they are never where the home owner wants the bathroom so we end up jack hammering the floor up to move all the pipes.

If you are good with the layout then building a bathroom is easy. But if you want to move shit then busting concrete is in your future

I’m not an expert so my guess this all leads to a septic tank.
