How to Build a Barn Wood Kitchen Sink Base

About: There is nothing I love more then making something new and usable again that someone else would have thrown out or torn down!

I knew from the minute I laid eyes on it that it would become our kitchen sink. Never mind that it had been sitting in a shed for god knows how long and it had, in fact, been filled to the brim with a mouse nest and had probably raised hundreds (if not thousands) of rodents for decades and was, in fact, totally covered in the resulting excretions. Nope, none of that bothered me! I took one look at this sink and my heart soared. It was perfect! Ok, so, it was counter depth and it definitely ended up “too high” for most people’s standards but, in the end, both Joe and I love our kitchen sink! Once we had our appliances installed I gathered my materials for building the base. (UPDATE: Hey guys, because so many of you asked, the kitchen sink came clean with just dish soap, hot water and a little elbow grease! Also, that outlet is not a GFCI because we installed a GFCI breaker at the panel to cover all of the outlets in our kitchen!)

Step 1: Gather Your Materials and Take Measurements

My materials all came out of the barn or were scraps from the renovation and, amazingly, the drain was in perfect condition – the only thing we had to purchase was the faucet for $70 at our local fleet store. All of my materials were leftovers in the barn and had been sitting there for a very long time. I knew I wanted to wrap the whole outside of the sink with something very big so I headed to my secret stash of amazing barn wood that I’ve been gathering and pulled out the biggest thing I had: a rough-sawn, ancient, 2×10!

Step 2: Four 4×4 Legs, 2x4s Laid Across the Top of Them for Support

It was a really basic piece that I had in mind. Four 4×4 legs, 2x4s laid across the top of them for support, and then the entire thing clad with barn wood. First thing I did was get the most accurate measurements of the sink that I could, which was much easier said then done – no part of this sink is flat or square on the bottom side. From there, I knew how long each of my 2x4s needed to be cut to fit totally under the bottom of the sink. From there I also knew exactly how tall the 4×4 legs had to be so I got to cutting.

Step 3: Make Sure and Make It Sturdy!

I screwed the whole thing together with my impact driver and 3″ screws (that sink is HEAVY – I needed to make this base very sturdy so I did). Here the base is complete, I will admit that I had a few doubts but I knew my 2×10 from the barn (as well as some more barn wood to be added) would completely cover the 2x4s but I was still nervous as we hauled it into the house and set it in place.

Step 4: Get Everything Hooked Up and Covered

Finally got it in place and the sink and dishwasher all hooked up! I added a barn wood shelf under the sink as well as one above the sink for extra storage. You can see how the 2×10 hugs all around the sink, I added this after I installed the sink and the base, it looks like its supporting the sink but really its just hanging out, the bottom base we just built is what is holding the sink up! I hate that you can still see some of the plumbing under the sink, I know most people won’t notice but… it bugs me. I plan on adding a wicker or wire basket to that shelf down there to hold all of our onions and garlic but I have not yet found the perfect basket yet but, when I do, it will hide our plumbing. (the left side of the base, you can’t see it, is totally covered by barn wood so you can only see the plumbing from the from.)

Step 5: Add a Towel Bar for Ease

I added the towel bar after covering ALL of the base and ALL of the barn wood with two coats of poly acrylic. Is that an old yard light above our sink? You’re darned right! It is my grandparents’ fifty year old yard light that hung off the pole of our little farm yard for many decades! It got replaced and when this old light came down I knew exactly where I wanted it to go Above our kitchen sink of course! I will put a prettier bulb in it someday, that one was the best one our little fleet store in town offered. The paper towel holder that we added to the bottom of the top barn wood shelf was something my grandparents’ made many years ago.

Step 6: A Tall Kitchen Sink

A couple of things I have to admit. The sink is taller then the counter top not because I wanted it to be, actually I planned on building the base so the sink would be about an inch LOWER then our counter top to make for easy wiping. However, when I ran the drain lines in the house I had expected to have vessel sinks in our two main floor bathrooms and, for some reason, my brain read that I need to have ALL of our drains that high. Sighs… so it was either rip off the drywall and redo the drain line (over my dead body…) or end up with a kitchen sink about four inches taller then our counter top. So, our kitchen sink is tall and in all actually, we both like it a lot. Because it is high it is MUCH easier for washing dishes etc.

Step 7: Finally a Sink I Can Wash Anything In!

I just have to mention, why do they even make sinks that are broken into two parts?! I know, they’re made for when people wash dishes by hand so one sink can be a dish drain rack but, quite frankly, I’ve washed a lot of dishes in this sink and I would never go back to a divided double sink because, for the first time in my life, my sink is big enough to accommodate even my biggest pans!

    Nice job! It's refreshing to see items being repurposed in new and interesting ways. My only criticism (unrelated to the actual sink) is that I would recommend changing out the outlet located near the sink with a GFCI outlet. It is an inexpensive (app. $15-$20) investment that could prevent electrocution and fire.

    Oh hey there I probably should have added this to the post, that outlet and the run of outlets on that wall are all on a GFCI breaker at the panel :)

    Yeah I've had bad experiences with GFCI outlets in the past, them going out etc. so I figured we'd be just as good doing the breaker instead :)
