A few weeks ago, I shared the basics of how to make a vintage dresser into a bathroom vanity. When I first decided I wanted to tackle this project, I had no idea what I was in for. I imagined I would paint the dresser, add a sink and a faucet and that would be that.
In reality, there’s a bit more to it than that. There were all kinds of little details I didn’t really think through when I first dreamed up this project. Of course in the end it turned out gorgeous, but I could have saved myself a lot of trouble if I’d had a better idea what to expect from the beginning. So I’m passing along everything I learned about how to make a dresser into a bathroom vanity. This is what I wish I had known when I started.

Adjusting the dresser height
A standard vanity is around 34 inches tall and my dresser was closer to 37 inches high. Add the height of the vessel sink and it would have been way too tall to comfortably use. I removed the casters which dropped it several inches but it was still a bit too high so I used our Dremel Multimax to cut another inch off of each leg.
Leveling the dresser
Before adding the sink, I needed to make sure the top of the dresser was level. Of course, this isn’t something you have to worry about if you are buying a vanity from a store, but most antique dressers aren’t even close to level. In fact, when I checked the top to see how level it was, I got a different reading in every spot I placed the level. Since the main reason it even need to be level is so that the sink will drain correctly, I placed the level right where the drain would be and based everything on that. I checked how level things were from side to side and front to back and then adjusted the height of two of the legs a little more until things were just right.
Cutting holes for the plumbing
The next task: cut holes for the plumbing. Since I was using a vessel sink, I didn’t need to cut a hole for the sink itself. The top of the dresser only needed a small hole for the sink drain and another small hole for the faucet. I set the sink on the dresser top where I wanted it to go, making sure it was centered and then simply traced the drain hole onto the dresser top using a pencil. I also placed the faucet where it would go and traced it as well. I don’t happen to have a hole saw, so instead I drilled several pilot holes and then connect them using my jigsaw.
I also needed to cut holes for the plumbing under the sink. Typically the water lines for the hot and cold water and the drain pipe all come through the wall into the back of the vanity and a hole needs to be cut in the back of the dresser to accommodate them. Our plumbing setup was a little different than most. When the plumbers replaced all of our old, messed up plumbing during the first part of our bathroom renovation, they needed to move the drain for our bathroom vanity to the floor. Because of this, I cut a small hole in the bottom of my dresser for the drain. I planned to also cut holes in the back of the dresser for the water lines, but it worked better for my particular dresser to just removed the back panel.
Making the back of the dresser flush
Many antique dressers originally had an attached mirror and an extra space along the back for the mirror to slide into place. This isn’t a big problem for just using the dresser without the mirror, but if you are turning the dresser into a vanity, it becomes a bigger problem.
As you can see, I had quite the gap between my dresser top and the wall. I ended up getting a 1 x 2 board, placing it in the gap, and tracing the edge of the dresser onto it. Then I used my jigsaw to cut out the outline. I attached this to the dresser using wood glue and nails and then filled in the gap with some wood filler. I sanded everything smooth and then painted this new addition to blend with the rest of the dresser. (This was one of those points where I wished I hadn’t painted the dresser until later in the process!)
Attaching the sink
Finally it was time to attach the sink and faucet. (I found both my sink and my faucet for a steal on Amazon and I totally love them.) I attached my sink using a waterproof adhesive making extra sure that everything was straight and lined up with the hole I had previously drilled. Originally I had some trouble with the drain leaking a bit which is a big problem anytime, but especially when you are using a wooden dresser below the sink. I was able to fix the leaking with some simple plumber’s putty underneath the drain. Then I attached the faucet using the directions that came with it and reattached all of the plumbing. (Yep, all by myself – it was definitely a proud moment.)
Fixing the drawers
The final step was modifying the drawers to accommodate the new plumbing. I wanted to keep as much usable drawer space as possible, so I carefully marked where each drawer would have to be cut to fit around the plumbing. Again, I used my trusty jigsaw to cut the drawers. (Yep, it’s my favorite tool by far).
During the cutting process a few of the drawer backs fell apart. I fixed those with some wood glue and then used scrap wood and nails to close off the holes I had cut. That way whatever we store in those drawers won’t roll around and fall through the cracks.
I only had to lose a tiny sliver in the center of the top drawer.
I lost about an 8 inch square from the middle drawer.
And the bottom drawer only needed the tiniest piece taken off the back. I didn’t bother closing this one off since this large drawer will probably hold towels and other large items that wouldn’t fit in that little hole. If our plumbing hadn’t had to be reconfigured to drain through the floor, I wouldn’t have had to modify this drawer at all.
The finished product
And finally, the fun part: putting it all together.
I am ridiculously excited about how this vanity turned out. And to be honest, I’m also pretty darn proud of myself for tackling this project on my own. If you’re thinking about making your own bathroom vanity, just know it may not be easy, but you can totally do it.
And it is so worth it in the end.

hello. your designs are awesome. I really like the DIY painted plan wall you posted previously. I have been trying to track down the paint you used but it is not available anywhere near where I live. The companies around here are able to match the paint if I had the paint chips or product information. Is it possible you still have it and could possibly share with me?
keep up the good work!
Carrie says
Thanks! The paint I used is available online or you may be able to do color matching by going to the website. They have color cards and brochures there that can be printed or you may be able to request one be mailed. https://generalfinishes.com/retail-products/water-based-paints-pearl-effects-glazes
Casey says
What did you use to seal/waterproof the top of the dresser? It looks great!!
Carrie says
Thank you Casey! I just used a brush on Polyacrylic. I chose polyacrylic because it is non-yellowing. Even though it is a water-based product, once it is fully dried, it works well at protecting against water damage. So far we haven’t had any problems at all with it!
Elizabeth says
Your work is so lovely! I have done lots of diy projects but no plumbing so please excuse my ignorance here. Here’s my dilemma. I want to remove a gross cultured marble countertop and replace with wood, then use sinks like you did. These appear to have a center drain where my current sinks sit to the back a bit. When I connect the drain, is the plumbing below adjustable to make the new drain connect? I’m not even sure if I’m explaining this correctly! Thanks for any wisdom:)
Carrie says
Elizabeth, Great question. Let me just be upfront and say before I did this vanity, I had no idea what I was doing with plumbing either. But based on what I know now, It shouldn’t be a problem to slightly change the placement of your sink drain. Most sinks have a drain leading down from the sink that leads to a P trap that leads to the wall, more or less. It shouldn’t be very difficult to change the distance from the wall by replacing a pipe.
Sarah says
I absolutely love this idea! My husband however is concerned with the top of the dresser becoming wet (we would be using this in our hall bath that the two children use), do you prep the top some how? Use a sealant?
Carrie says
Hi Sarah, I understand the concern because our kids use this bathroom too and sometimes they get a little overzealous washing their hands. I used several coats of polyacrylic sealer over the top of our vanity. We have been using it for about a year now with no problems. Sometimes water does get on the top and we just wipe it off with no problem.
Cynthia says
It’s beautiful!
Do you remember the names of your faucet and vessel sink?
Carrie says
Thanks Cynthia! The sink is here: http://amzn.to/2xCJuwl. The faucet I used is unavailable but this one is very similar – http://amzn.to/2wWZ6xE.
Cece says
Would you recommend sealing the inside? I’m using a beautiful mid century modern piece and I’m scared of it warping inside due to moisture.
Carrie says
Cece, I didn’t seal the inside of mine but that is a really good idea, especially for a special piece of furniture. Of course, no moisture should be getting to the drawers but we all know things go wrong!

The vanity is beautiful. I have been working on one for my bathroom for months. Part of the delay for me has been having the pipes in the floor and not wanting to cut three holes or a large section out of the dresser bottom for fear there will be issues later with it being able to hold the weight of the sink and water without starting to sag. Then I have had to figure out how to keep from creating an S trap due to the floor drain pipe. Have you had any problems with the plumbing the way you have it set up?
Carrie says
Plumbing can definitely be tricky – especially since every situation is different. We have been using our sink for over a year now with no problems. When I was figuring out the plumbing of the sink, I was trying to figure out the whole s trap question as well. One thing that helped for us was I was told since our main drain line is quite close to our sink plumbing we didn’t have to worry so much about the configuration. Of course I’m not a plumber so this isn’t professional advice! Good luck!
sue says
Looks great and thanks for all the tips. How did you measure where to cut the drain hole for the sink to be perfectly aligned to match the drain pipe underneath? I’m about to do this project, and cutting the hole slightly too far to the front or back is giving me stress!
Carrie says
Hi Sue! Good question. When you cut the drain hole, it needs to line up correctly for the sink as well as the plumbing. The sink is the more important part because pipes can be tightened or slightly loosened to help make the spacing work. Or you can add a small pipe to connect two parts that are bit too far apart. To find my drain placement, I laid my sink on my dresser top, making sure there was enough room behind it for the faucets and enough room in front to look balanced. Then once it was centered, I marked where the hole needed to be and cut it. Then I made adjustments to the plumbing as needed.
Christine says
Is that final picture your sink in place? Trying to figure out where your pipe is coming up from the floor?
Carrie says
Hi Christine, great question. The final picture is actually before we installed the vanity in our bathroom. I took photos of it on our back porch because our bathroom is small and hard to photograph. But you can see final photos of it in place in this post: https://www.lovelyetc.com/modern-farmhouse-bathroom-the-true-final-budget-and-source-list/
Kimberly says
Looks beautiful! Did you have to put in new drawer slides/tracks for your drawers? That’s the problem we are having with ours since ours had center drawer slides and had to be cut and removed due to the plumbing. We tried putting in metal slides and it’s not working well. I can’t figure out how to fix that part! Thanks!
Carrie says
Hmm, good question. I couldn’t remember since it has been a couple of years, but I just checked and our drawers don’t have drawer slides. My suggestion would be to try adding slides to the sides but it sounds like you already tried that. I’m sorry I can’t help more – good luck!
