Replacing Undersink Plumbing


Hello all, and thanks in advance for any help you can give.

I have a wall mounted sink in a very small half bath. The previous homeowners plumbed both the supply lines and p-trap with PVC, so I would like to replace the lines with something like this:

http://www.amazon.com/KOHLER-K-7605-.../dp/B0000B0PI4

And the p-trap with something like this:

http://www.amazon.com/KOHLER-K-8998-.../dp/B00155MSWM

What I think I need for the water lines is a 1/2" cpvc to 3/8 NPT, and just a simple PVC trap adapter for the drain.

Am I on the right track? Any thoughts on where to source the CPVC to NPT adapter?

Use braided flex supply lines and a pvc trap. No need for chrome unless you want the looks.

Agreed on the use of braid and PVC if I didn't care about the aesthetics, but since it's exposed, I do.

Install drop eared elbows in the wall and use chrome nipples to come out to the valves.

In that case- Cut the water stubs shorter so minimum pipe is exposed and use the angle stop of your choice. Put escutcheons on for trim.
Use chrome plated risers to the sink. You can buy a bender to form the offsets if needed.
Also you can use a chrome ptrap and tailpiece. A standard PVC trap adapter will work at the waste arm. If set back far enough, a 1.5" box escutcheon will cover the trap adapter. After doing all the above- all you'll see is chrome. It'll look sharp

Thanks! Picked up these parts last night. This will work perfectly. I'll post pictures when its all done

TheEplumber, I was going to go the PVC route, but the angle stops I want have 1/2 in. Female NPT connections on them, and I'm wary of screwing PVC and Metal together.

That is why I suggested a drop ear elbow with a chrome nipple.
