Hi, I'm adding a shower to my existing half bath. I have a question about where to get my water.

Option #1 - Supply both hot and cold from lines that supply the existing faucet. 1/2 inch copper feeds the faucet. I like this option, but I don't know about pressure considerations. I would tap into this, and run copper pipe to shower stall.

Option #2 - Supply both hot and cold from lines that supply the upstairs shower/tub. 1/2 inch copper feeds the tub above the ceiling. I'm thinking this option might give me pressure problems if both showers are being used at the same time.

Option #3 - Supply hot and cold from wherever the faucet is getting its feed. I'd like to avoid this if I can.

Please advise.

If that's the easiest one I like it too. If you're supplying to sets of faucets off one 1/2" branch then it would pass my code. Tour volume worries are needless, Good luck, tom

Thanks Tom.

Maybe I misstated... Option 2 would be easiest, but Option 1 is not that much harder, just more copper to run... it is my favorite because while faucet and shower being used same time is less likely than two showers.

I'm hoping you meant that Option 1 has no volume problems, but Option 2 does, so I'm choosing the right option.

Thanks again

Same answer for #2, Whatever's easiest to install. Plumbing wise they're both the same. Go for it! Good luck, Tom
