Q. I'm a big fan of your plumbing column. We have a classic 1950s ranch with one big pink bathroom that we are remodeling next year. We have a very long countertop with only one small sink and a medicine cabinet. When we install the new countertop, can we add a second sink and a medicine cabinet since we have all that extra space? Is this a bad idea since it is the only bathroom in the house? It seems to us that double sinks are a master-bedroom kind of thing. Thanks for your professional opinion.
A. I say that whenever you can use a home's existing plumbing system to your advantage, go for it.
The good news is that you should already have the sink water and drain lines right there under the countertop. So if your existing plumbing is in good shape, a licensed plumber should be able to "twin" in a second lavatory sink.
I've done jobs like this. As long as the second sink can be installed according to local codes, it can be a very nice addition to any bathroom.
Now about the practicality of double sinks in the only bathroom in the house. Well, I've lost count of the number of times I've used my living-area bathroom, only to find some laundry soaking in the single sink for that bathroom.
Bottom line: Adding a second bathroom sink can be a good investment for you, and going from single to double hopefully should be no trouble.
