Hey everyone! I'm a new homeowner looking to install a sink in my den and I've come across some water lines in the corner that were left unused by the previous tenant. My father-in-law, who's been into renovations for a while, says these lines can actually be used for a sink. We've confirmed that the drain works, but I'm hesitant to remove the caps on the water lines because, well, water. I'm uncertain about how to proceed from here — what guides, videos, or resources can I check out to learn how to turn these into a functional sink? Plus, what materials will I need to gather for the project? Any advice would be greatly appreciated!

The water lines seem to be CPVC, which is a good sign! You’ll want to get a valve like the one I linked from Home Depot to connect to braided hoses. Once you have the valves set up, it’s just like installing any other sink — pretty straightforward! Here’s the link to the valve: [Home Depot Valve](https://www.homedepot.com/p/BrassCraft-1-2-in-CPVC-Inlet-x-3-8-in-Compression-Outlet-Multi-Turn-Straight-Valve-PR14X-C1/202047069).
Those pipes look like they’re made of Charlotte FlowGuard Gold CPVC. You can find some useful resources online about it, and search for videos specifically about using CPVC for sink installations. Here’s a link to a video that might help you get started: [YouTube Video](https://www.youtube.com/watch?v=2w_Wmv-raBc). Good luck with your project!
Just a heads up, those pipes are PVC, and it’s generally not safe to drink from them. That could be why they’re capped. If you go ahead with the sink installation, I’d recommend tracing the lines and replacing them with copper or PEX for safety. But since they look like a rough in, you might be okay using them, especially since they’re labeled NSF certified.
Well shoot that sucks. Luckily we weren't planning on drinking from them, just for cleaning glasses and stuff. Unfortunately they have concrete poured over them and I can't see any lines outside so.. I guess that means we just can't use these?
Those lines look like they’re meant for a wet bar sink, especially since you’ve got a drain and hot/cold supply. If you own the property, you should look up videos about 'finishing rough in plumbing for sink' on YouTube to get some good tips. If you're renting, though, you might not be able to modify them. Just an FYI!
Awesome thanks I'll Google that. We are homeowners so I definitely am trying to make a wet bar!

You rock thank you!
