Hello. I live in a 100 year old home with old plumbing. We're remodeling the bathroom. I just bought a solid surface top and a new vanity to replace the old ones. The bathroom only had 1 sink before, now I'm replacing it with a two sink vanity top.
Pardon my ignorance, but what is done with the plumbing area as far as drainage and hot/cold water connections to accomodate the change from 1-sink to 2-sink top? Thank you.
You can use the existing trap and use a "center-outlet" waste TEE to connect both basins. The parts are those used commonly on kitchen dbl bowls. To use separate traps, get a 1 1/2" Dbl WYE and connect that into the wall. With reducers, connect a 1 1/4" P-trap to each WYE inlet.
In an old house, you may find the connections in the wall to be a challenge.
Simplest way to do the H/C supply is to TEE off the existing stops (shut off valves). Better would be separate stops for each basin. Depends on what's there and how much trouble.

Correction: I should have noted that you have to replace the trap with a 1 1/2" size to do this. Jim
Thank you, Jim. I'll try that.
