Adding sink to washer and dryer area


I have an existing washer and dryer area that we are remodeling and looking to make it a lot cleaner and presentable. My end goal is to have the washer and dryer surrounded by a built-in countertop, and that same countertop to have a sink in it. I am not a fan of the utility tub style/look, as I know that would probably be the easiest solution.


How would I go about adding in proper drainage/venting for a sink on my current layout? I assume I could just put a T for the water lines just about anywhere?


Existing System:


End Goal of what it should look like:

Pretty much the same as with any other sink.

Lol I wouldn't be posting up this question if I already knew where to add the drain for the sink. So if you have some specifics, that would be helpful.

Re: Adding sink to washer and dryer area


Hard to tell here exactly from just pictures.

But your sink is going to be to the left I believe....so you will need drainage fall and venting and supply. Supply should be easy. You will also need dryer venting in there , which, I don't see...and have no idea whether you can go up with it or latteral.

I did something something very similar with reconfiguring a laundry room framed basically in 2x4 stock with supply and DWV on an adjacent wall,.

Trying to get that plumbing/venting and dryer venting rearranged in a 2x4 wall can be a nightmare,

I basically build a new "wet" wall" in front of existing wall. To get dryer venting thru if going out lateral, I set that wet wall out a couple of inches and notch the wet wall studs for dryer venting.....or DWV pipeing.

Or, you can use your wet wall studding on the flat to give you plumbing room.

Can't see very well....but not sure your present venting on your WM trap is correct......

And as a suggestion only, you may want to build a slight platform to raise those front loader's up a few inches or so....as they can be somewhat cumbersome bending all the way over to load and unload.

Re: Adding sink to washer and dryer area


Additional consideration might be if you want to raise your WM supply box up above the counter or sink.... kinda ruins the aesthetics, but I find it nice to have easy access to the supply valves....???


(Oh.....and just in my experience, your counter will not end up looking neat and clean like a living room display counter. It will become a place to pile clothes and laundry detergent and anything you don't want showing in your kitchen...LOL.... but honestly, you may want to consider full cabinets above... not as nice a picture as you see there...but maybe more practical in a "catch all" laundry room.....just my experience.)

Re: Adding sink to washer and dryer area


If you are in a IPC state you will need 3 inch where the washer enters the branch drain.


The vent for both must come off the top above the washer connection. Who ever plumbed that did it entirely wrong. Hope the rest of the house is better.

Re: Adding sink to washer and dryer area


Thanks for the help everyone, for more clarification: This is a first level space.

Yes, the sink would be approximately where the washer box is currently

Dryer will be vented laterally out of an exterior wall to the right. I wasn't planning on having the vent pipe set in a wall unless I do a bump-out wall that could accomodate for its width.

Yes! I was thinking of doing exactly this since there is a web of plumbing already (some of it is for a bathroom on the other side)

In examining my system versus what I have seen/learned about vents, I was thinking it may have been done incorrectly. Before taking off the drywall we had used our washer and dryer (venting into a bucket/the house ) here for about a year with no problems but we are now ready to get a real long-term setup going.


Anyone have suggestions on how I can properly run these drains/vents? I will post up a sketch on what I am thinking later.

Re: Adding sink to washer and dryer area


Could you use the space under the floor behind the wall to the right for the dryer vent.

I installed one a few years ago, she has not complained about it. It sure seemed like a great idea. Hooking up a stacked set in a broom closet is not fun. I think this will become code after the patent protection come off so there will be brands.

Re: Adding sink to washer and dryer area


I like it except for the front loaders. Our top loader does a load in less than a half hour. My daughter in law got tired of waiting over 2 hours for a load in her fancy expensive Bosch front loader so she just got rid of it for a $500 Whirlpool white basic top loader.

Re: Adding sink to washer and dryer area


We are talking about the venting of your plumbing not the dryer vent.
