Master bath vanity: copper pipe help

Hi. If this is not the right place for this question, please redirect me.
I have a two story condo in Twin Falls Idaho and I’m replacing a master bath vanity with one that looks like furniture with a large bottom drawer and legs that you can see under. The four copper lines and valves (double sink) come out of the floor about 6-8 inches from the back wall and will interfere with the drawer and can also be seen underneath the vanity. It’s an adjoining wall to the next door unit. Can I open the floor and 45 my way into the wall and then back out so lines and valves will be coming through the back of the vanity rather than underneath through the drawer?? I haven’t opened anything up yet except for a small hole in the floor to see what’s under there. Any other ideas that might work better? I can provide pictures if that will help and if I can figure out how to upload them. Sorry but I haven’t used this site for quite a while. Please help if possible. Th


Adjoining wall is on the right

Looking straight ahead at adjoining wall
ank you

Welcome back. I moved you to your own thread.

It looks like you can open the wall up and drill the plate putting the pipes inside the wall.
There should be just enough room to drill next to the mfg floor joist.

If that is an exterior wall, that would explain why it comes up from the floor. In cold country, you don't put water pipes in exterior walls or they can potentially freeze and break.

In that case, it would be advisable to build a double wall, and keep the pipes on the warm side of the insulated wall.

It’s not an exterior wall. It’s a side wall adjoining to the next door unit. I just haven’t been in the wall yet and wanted some advice before cutting things up. I’m a little sketchy about sweating copper under the floor and in the wall especially sweating vertically and also with water off but I’ll have water sprayer and fire extinguisher ready just in case 🔥 😰

If you were cut those feed lines close to the floor with just enough left to attach the valves, will it still interfere with the drawers? You can use Sharkbites rather than solder joints. They will be exposed just in case.

They’ll still be seen under the cabinet and I’ll still have to get them past the drawers to get to the sinks above. I’m going to tile the floor which means I’d have to cut holes in the tile for the pipes. I think now the only way that makes sense is to open the wall and route them inside the best I can and then come back out a few feet higher.

To help protect the area from the torch flames go buy a few pieces of ceramic tile. I put them behind whatever I'm using the torch.

Yep, get a different vanity.
