I am replacing a 60 inch single sink cabinet (sink in the middle) with a 60 inch cabinet with 2 sinks on either side and drawers in the middle cannot use connections as they are. Any suggestions?

Hey TJ:
Water should not be an issue. Should just be able to purchase long braided hoses (20-30") and connect them from shutoffs to faucets (see pic...but longer ones).
Now..the waste line.
What material is the waste line...? Copper or PVC?
If PVC, just cut the pipe behind the old trap and connect a coupling on and run new trap and desanco ftting over to new sink..then branch off above that trap to pick up other sink
If copper, will need to purchase a shielded coupling that transitions from 1.5" copper to 1.5" PVC pipe (see pic.) and then run new PVC pipe and fittings to new sink.
That should do it for you.. unless I missed something..
Let me know... Mark

I take it you're referring to lavatories or vanities and not kitchen sinks.
You have options to connecting the sinks up to drainage. You may wye off from the stubout and install two traps **or** you can keep the single trap and use a continuous waste to tie the too lavs together using a end or center outlet, (see images). Good luck, Tom

Let me add a bit more. I would swap both angle stops out for 1/2X1/4X1/4" double outlet stops,(see image) to supply the two fixtures. Good luck, Tom

Problem is where the water feed and drain pipe are now, lines up with the drawers in the new cabinet. Opening for the 2 sinks are directly under the sinks the only solution I can see is to reroute inside the wall

opening for the 2 sinks are directly under the sinks the only solution I can see is to reroute inside the wall Let's get together on terms so we're on the same page. Sinks= kitchen sinks, lavatories/vanities= bathroom sinks, stubouts= the pipes coming out of da wall.
If, by "opening" you mean drainage stubout why couldn't the center outlet waste be used. Rule of thumb sez, It's a lot easier to move water then it is to move drainage. Can you fit a trap between the two fixtures without hitting a drawer? Regards, Tom

Rerouting drain pipe sounds like a good idea... but water can be worked out either with new shutoffs as speedball1 suggested.. OR
Could use 3/8" braided compression hoses, a 3/8" compression tee and then 2sets of 3/8" x 12" braided hoses I showed you earlier. That should fix the water issue.
Let us know... Mark
