I have an unfinished utility room with a shower set on one wall. I’d like to add a utility-style sink to the right of the shower, but no plumbing hookups currently exist. Both hot and cold water lines come in above the shower from the left and down the wall. What is the best way to tie into existing copper plumbing to add sink hookups?

I have no experience working with copper plumbing and I don’t currently have any associated tools, though I am generally very handy. Tool acquisition/learning curve should be considered but not be a dealbreaker for any answer.

You add a Tee to each line by whatever method is "best for you" and you extend the lines over by whatever method is "best for you." Do realize that if anyone uses the sink while someone is using the shower it's likely to result in an angry shower user.

What's best for you is on you to figure out.

You could keep it all copper sweat by soldering in copper tees and pipes. You might enjoy learning a new skill. You might be frustrated figuring it out yourself. It might be an increasingly irrelevant skill to learn.

You could get it over with quick by using quick-connect fittings and PEX (or copper) for the new pipe.

You could do any number of other methods, all of which will work, and someone would consider them best, even if most people would not. We can't tell you what's best for you, and telling you what's best for me (I have all the tooling to solder copper, and I have PEX crimping tools, so I don't use quick-connects and I don't run new copper where not required to be metal) won't really inform your choice.

You'll also have to deal with the drain and vent, of course.

There would be soldering. It does require some practice but it is not rocket science and needs some tools

Easiest would be to use Shark Bite connectors, requires some thinking and measuring before cutting. No open flame no risk of fire.

And there are the compression fittings.

In all case inserting a T would require one side to be movable.
