Moving shower pipes, logistical question (diagram included)
 
I'm planning a renovation to a small bathroom and want to expand the shower stall. The shower currently is backed up to a closet of equal width, so it would be simple to close up the closet and expand the shower.

The potentially difficult part is moving the plumbing, which is something I don't know much about. I can sweat pipes, but I'm not sure of any potential problems in moving the pipes in the way I'm thinking of doing it. Here's what I plan to do (diagram not to scale, shower is actually more square shaped):

The red lines are the hot and cold copper pipes coming up through the back wall of the closet. Blue lines are where I'd like them to be, where the closet door currently is and then I'd just wall up the door opening.

I was thinking I could pull up the floor of the closet and bathroom and turn the pipes to run through the floor and then up into the new wall. What I know nothing about is is this is practical, and if there are any negative implications in doing it this way.

Is there a better way to move these pipes? Any suggestions, concerns, etc?

Thanks

Hi Mike,

It seems like this is just a simple exercise of adding some more pipe to lengthen the current pipe run to the new location, correct? If so, then that should not be a problem at all. One tip when prepping copper for sweating, clean it very well (like new) and it'll be much easier to sweat together.

One question, how are you going to address the drain location?

I was hoping to leave the drain where it is. The shower is actually not as big as my terrible diagram makes it look. It's a roughly 3.5 ft x 3.5 ft stall. Looks more like this:

Not sure what the protocol is for drain placement. I know if it was a much wider stall I'd need to position the drain in the center. Think I can get away with leaving it as-is for a roughly 1.5 ft expansion?

You can definitely leave the drain where it is currently, provided the expanded area has the proper slope towards the drain. Is this a tiled shower pan?

Yep. So I'll be re-tiling the whole thing after tearing out the old stuff and doing a new custom-sized pan.

Moving the drain will make your pan easier to build----Not absolutely necessary--but a better job.
