Hello all, I just discovered this forum and this looks like a great DIY resource so I'm hoping I can get some advice. I've done some DIY projects before but plumbing projects have been limited to installing traps, new shower valves, toilets, etc... and I've never had to re-locate any existing plumbing.
I'm starting a bathroom remodel and as you can see in the attached pics, I have a shower that's adjacent to a tub/shower combo. My wife wants to get rid of the tub(already done) and put a his/her vanity sink in it's place along that wall. This is a single story home so I'm hoping I can use the tub drain and the water supply pipes for the tub/shower for the new vanity. Is this as easy as running the vanity drain into the existing tub drain and running new copper supply pipes to the existing tub/shower supply pipes? Are there special fittings that I need to use? I'm assuming the vertical PVC is the vent pipe so I'm hoping that I won't need any additional venting. Definitely hope this won't involve breaking up concrete.
Please let me know if this is a pro level project or if I stand a chance on my own, with a little help from you all along the way

There will be a trap under that tub drain so you don't want to drain the sink there. If that is in fact a dry vertical vent it would be n excellent place to cut in a tee for the sink drain.

it is as easy as you describe..
i can't open the pictures so i will speak in general terms.
yes extend the tub drain up into the vanity and use an AAV for the vent.
extend the hot and cold into the vanity, put a shut off on each pipe and connect to the faucet with flexable supplies. note.. some faucets come with flexable supplies already attached to the faucet base..
just saw my friend from NC post and i neglected to say, remove the tub trap and put a new one under the vanity..

Great! Sorry for the newbish question but how can I verify that it's a dry vertical vent? Follow it up to the attic? It's a single story house so I can't imagine what else it would be though. So I can just install a T and run the vanity trap right into the vent (if it's a vent)? This will be easier than I thought.
What about the water supply lines? Can I just sweat in some new copper pipes and extend them through the studs to the adjacent wall, followed by new valve installations? Thanks for the help!

If it's a single story home then yes, it's dry vent. Just lay a tee against the pipe so that the branch is about 19" from the floor, mark where the inner portion of the hubs of the fitting will be and cut that section of piping out. Glue the tee in place and you're all set. Personally I'd cut the copper and run pex on to it's destination but you can use copper if you prefer.

Packy he can't easily remove the trap because it's under his slab.
NC Plumber if it's a dry vent would there be any concerns on how the vent is connected to the actual drain line? I have seen people when branching off a vent use vent tees, or sanitary tees, could that lead to a potential issue?

I don't know what you mean by "standard" tee, but you need to use a sanitary tee.
