Toilets, Sinks, Showers, Tubs and Disposals - Have 1 sink in master bath... want 2 sinks:

Hello everyone :)

We are in the process of buying our very first home and are already looking at improvements we want to make. This one concerns the master bathroom which only has a single pedestal sink. We are wanting to have dual sinks in the master bath, but are not quite sure what all this would involve as we know NOTHING about plumbing :(

- This is a photo of the actual sink in the master bath (http://celura.net/kinggeorge/mastersink.JPG)

- This is a photo of the type of sinks we want to put in (two next to each other) (http://www.pegasusfaucets.com/vn_427-353_422-719.html)

Not quite sure if all of this will fit yet. If not, we will just add another pedestal sink. Either way, my question is about the plumbing setup for this. I realize that each sink will need its own hot water/cold water supply as well as a drain. Since we will be adding a second sink, how will this work? Is there a main drainpipe that they will both connect to in the wall?

I'm honestly completely clueless about plumbing and have no idea what the in-wall setups are like. If anyone can give me an idea of the cost/work associated with what we are trying to do, I would appreciate it very much.

Thanks!

Assuming the 2 vanities will fit next to each other, there should be no problem. You will need to remove a portion of the drywall to expose the plumbing in the wall, but extending the drain line and the water supply lines is pretty simple. If you don't want to do the plumbing work yourself, it shouldn't cost more than a few hundred to have a plumber do it.

If you use a single cabinet with 2 sinks in the top, you could connect everything within the cabinet and not need to cut into the wall. If you look at the pipes behind the pedestal, you will see that everything is connected there and you just need to extend those connections to the new lav's. It will take some of the space at the back of the base cabinet, but usually the drawers in such cabinets are short to allow for such connections.

Thank you very much for your help!

So you're saying that I can use the same drain pipe for both sinks if I do a double vanity instead?

Check your local codes to see if they have a problem with the piping you want to do. I see no problem with it but as stated, if you use two of the vanities in your picture, you may (if there is no space at the back end of the drawer and wall) lose at least one drawer. It also looks as though you will have a space to fill in where the tops of the two vanities over hang the cabinets. You can make a strip to cover this and stain or paint it the same color. The drain piping will be similar to a kitchen sink continuous waste line for double sinks. Good luck with your project.
