New Single Basin Sink Install (downsizing double sink drains down to one) - Major Hoff Takes A Wife

New Single Basin Sink Install (downsizing double sink drains down to one)

This is our new gorgeous sink. But it wasn’t always this pretty. Today I’m highlighting how we changed out the sink from a stainless steel double sink to a single basin sink.
New sink with single drain
This is our old, ugly, builder grade, nemesis- I mean sink. 

So hopefully you saw my post yesterday about my new awesome Moen Faucet. In case you missed it, you can find it here. This is sort of a 2 step project. The first part (yesterday) was getting the faucet into the sink basin. The second part is getting the new sink basin in. That proved to be harder than expected.
First, We had to pop out the old ugly sink. This was the part that sucked the most. You are underneath the sink unscrewing clips that hold the sink in (this is not comfortable for any human being. Bring a pillow for your back!). You also have to disconnect the pipes. We had a 2 drain system (one being a garbage disposal). We untwisted the garbage disposal first and then disconnected the second drain & the water lines from the faucet (all power and water was off for this one!). Once we were totally disconnected, we removed the sink. It came up easier than I thought. My husband kind of bumped it up from down below and with a nice big pull the hideous sink was history!
We were replacing it with an awesome white sink basin that I found sitting on a shelf at my Habitat for Restore Store. It had been a display at Lowes previously and I got it for a steal!
To set the sink in place, we used a bead of construction adhesive along the lip of the sink that would fit against the countertops. We placed the sink in exactly where we wanted it and waited a few hours for it to dry and hold. We also took that time to connect the water hoses from the faucet underneath the sink. After that was over, we began our joyful experience with plumbing (insert sarcasm here).  We were going from a 2 drain set up that looked like this:
Original plumbing 2 drains and disposal
and we were trying to make it a single basin (with the drain connected to the garbage disposal. After we disconnected the sink drains we were left with this:
Plumbing set up with out the sink drains installed The original part that the disposal twists into is actually still in our old sink. We replaced the disposal but not the sink connection part earlier in the year. The sink drain/disposal parts were still in a bag in our garage and so my dad was nice enough to add that to the sink before he left our house to go back home. Because the single drain is in the middle of the new sink, our garbage disposal moved over and the line that went horizontally from it was too long.So off to Lowes we went to find the pieces that would fit the leftover plumbing pieces like a puzzle. A very hard puzzle.
These were some pictures that I texted to my husband at some point during my 4 trips to Lowes in 1 day adventure:
Wrong plumbing options
We discovered several things. Like the pipe that connected to the disposal had a funny little lip that we needed (not threaded). At this point, my Dad the handyman is gone. I’m texting pictures, but it’s getting really complicated. I would get home and pieces wouldn’t fit, or the seal wasn’t good enough, or we’d have to cut the larger pieces with the miter saw. At 9:30 at night. We finally got a set up that worked, but it would drip a few drops now and then. I knew the specific piece we needed, but Lowes was out of stock, so we made do for about 5 days with this not-quite-ideal set up. And we keep a bucket underneath it, along with towels. But at least everything “worked” and I wasn’t without a sink for those 5 days.
Here is the temporary set up that I would NOT recommend:

Finally we hit the jackpot and Lowes got the part we needed in. And then it was like magic. If we would have had this part from the beginning, I would have said replacing the sink was easy peasy!
Here is the magic set up!
The Winning Plumbing set upWhat I love the most about going to the single drain is that I have soooooo much more room under my cabinet now. Before, the plumbing and the disposal took up a lot of the cabinet space. And they were each in a bad spot, and not close to one another. Look at the size difference on each side now— all my tall bottles fit!

I went ahead and put down a really nice heavy duty shelf liner that was clear, but I didn’t like the way it looked, cause it was kinda plain, so I put some pretty wrapping paper cut to size down first, and then topped with the clear shelf liner.
One of the last steps is to caulk the sides of the sink. I watched a few youtube videos and since I’ve used caulk on other projects I thought I’d be good to go. Not so fast. We purchased silicone caulk, because it was the best for waterproofing. What I didn’t know is that the regular caulk is pretty forgiving and will wipe off fairly easily. Silicone, not so much. After a frantic google search I discovered that rubbing alcohol works well. WHEW! Lifesaver! So now the sink is in and we are happy. Here are some pictures of my new favorite part of my house:

I am love with the single basin. Since we are a large family, I tend to cook with bigger pots and pans. They all magically fit in here! It’s just perfect for washing cookie sheets, or piling about 8 cereal bowls in at one time (not that dirty dishes will ever sit in my sink now!).

The Walden faucet adds the classic touch, and goes with the vintage/farmhouse look that I love so much.

So what do you think? I wasn’t intimidated by the faucet, but I was with replacing the sink, unhooking the disposal and replumbing the lines. In the end they weren’t that bad at all. I did need hubs for the heavy lifting part. I’m so glad we did this little reno. We estimated it would take a couple of hours, and really……..if we had every single piece, it probably would have. That said, we didn’t. So it took closer to a week. Isn’t that how most DIY projects go anyways?
Thanks for taking the time to read my installation story, hopefully it will help you! Be sure and stop by my last post to enter to WIN a free Moen faucet!

I'm sharing this post on these pages, be sure to check out their parties!


  1. I am getting ready to do the same thing (same sink, different faucet, taller) so I was very happy to see this. thanks so much. It gives me a little more self-confidence. Joyce

  3. Hi, URGENT HELP needed! What is that magic part exactly called? Can you link the lowes link? We are in the middle of doing this and would GREATLY appreciate it! Great write up btw! Thanks, Kelley

    1. I do know the part! 85580K Disposal tailpiece for in-sink-erator Inlet 1-1/2" outlet 1-1/2"
      it also has 47394 above the SKU. The SKU reads 04622400533. Hope that helps!

    2. Hi, I'm about to do the exact same thing with my sink. I think I've found the magic piece you were talking about . I've never done any plumbing before in my life. Could you please explain how you connected the piece to the disposal and the rest of the pipes? Did you just slide it on and that was it? Or did you have to glue/seal something? Thank you!

    3. That's the piece! We didn't have to do anything but just twist pieces on, kinda like putting a lid on a pickle jar. I don't recall anything complicated. Glad to know people are using the tutorial!


Thanks so much for commenting! I appreciate it and love communicating with you!
