DIY Bathroom Vanity with Bottom Drawers

Update your bathroom by building a new bathroom vanity with large drawers. 

Remodeling a bathroom on a budget can be done! I know, this is the second one we’ve done in our current home (you can check out the master bathroom remodel here). 

One of the priciest parts of any bathroom is the vanity. But you can build one yourself and save tons!

I partnered with Kreg Jig, to share the free build plans for this 42″ DIY bathroom vanity with bottom drawers. Now you can build your own bathroom vanity and save money too!

Most people wouldn’t dream about building their own bathroom vanity, but after building the kitchen cabinets in our recent kitchen remodel, I learned that cabinets are not as hard as one would think.

The trick to making a bathroom vanity, you need to take your time to be precise.

Cut all your boards straight and ensure everything comes together at a 90 degree angle. Then you will have a wonderful bathroom vanity that you can show off to everyone!

DIY Modern Bathroom Vanity

We wanted a space that was clean and modern, with a little rustic goodness thrown in. And what is more modern than open shelves?

Because this bathroom is our guest bathroom, the idea of open shelves is even more amazing than just for looks. You can have towels and other necessities stored in the open so your guests don’t feel weird about going through your drawers. 

The other reason I love open shelves in a small bathroom is because they help make the space feel bigger. Instead of a giant closed in cabinet, they allow for more space in the room visually.

But we also needed storage!

Even though it is a guest bathroom, I wanted lots of storage!

Sometimes I use the storage in the guest bathroom to store things I don’t need to use very often. It a bonus spot for those weird things I need a couple times a year!

To keep with the modern bathroom vanity feel, we put the drawers on the bottom of the cabinet instead of the top and I love it so much more!

Putting vanity drawers on the bottom means the drawers can be larger because you don’t have to leave room for the sink and plumbing.

Just look at all that storage space!

42″ Bathroom Vanity

To keep everything on a budget, I designed this DIY bathroom vanity to be a standard 42″ bathroom vanity. That way, it can fit an off-the-shelf vanity top.

The cost saving of buying a pre-made vanity top was great. But I also love that as soon as we finishing installing a bathroom vanity, we can quickly install the sink and be ready to use it.

I'll email this post to you, so you can come back to it later!

It makes this bathroom vanity project truly a weekend project!

We chose this simple white vanity top with seamlesss sink. I love the clean lines and it almost disappears into our white walls. So now the beautiful wood of the vanity is the focal point.

Building a Bathroom Vanity

And let’s talk about the wood we used for our gorgeous bathroom vanity…

Because bathrooms tend to have a lot of water in them, I prefer to use hardwoods to build the cabinets. Hardwoods will hold up better over time, and we all know how much use a bathroom can get.

I knew I wanted a wood that was beautiful all on it’s own. Something with grain and character!

So we went to our local lumber yard and found this beautiful ash wood with lots of color variation.

Since this build is a simple one, I decided to test my skills as a woodworker and mill my own boards.

This required me to buy raw boards and plane them to the proper thickness. Then cut the sides straight and the width of the boards to the proper size.

It was a fun test of my skills, but I know that not everyone is ready to do that. So I made sure to use standard lumber sizes with all my boards so you can buy pre-milled boards to build your own vanity. 

To make the build process quick and easy, I used the Kreg Jig to join together my boards. This little tool makes super strong furniture that I can be confident in. But the pocket holes are easy to make with just a drill and the jig.

So excited to build this! Can you recommend 1-2 other types of wood that would work well for this project that might be easier to find at a local home improvement store?

Any hardwood will be fine to use. local home improvement stores don't often have large selections of hardwood. Don't be afraid to look for a local lumber shop, you may be surprised at what you can find.

I am trying to determine whether it would be possible to adjust this to make an 80-84" vanity with two sinks. So afraid of making the wrong decision and adjusting the cuts incorrectly after buying the materials.

Sorry for the delay in responses and I also have seen your other question. The short answer is yes it is possible. I would leave a single center support for both vanities. As for being afraid, I understand. You are going to make a mistake. Just accept it. Sometimes it's a small mistake that can be corrected and sometimes you have to buy more material. I make a mistake on almost every project I build. Keep in mind though, even if you buy more material, most likely you will be paying less overall for your vanity. You also get the pleasure of building it yourself and getting better at a skill. You can do it and I hope you share pictures with me when you are finished!

Could I double the length of the vanity? I want a double vanity that is about 84-86" long. would I need to do essentially two of these vanities and joint together with one support?

Hi! I just signed up.

I have some wormy maple boards, that I am considering using for a bathroom vanity. Is this a good wood to use? And what's the best way to seal it? I like all the colors in the boards! Bathroom is small and plan to use light colors for walls and ceiling. But thinking to use medium or dark for fixtures and floor.

I love wormy maple, its a hard wood but would be fine to use. The best way to seal it is subjective. I have another post comparing all the sheens from waterlox that might help you decide.

The wood grain looks amazing! Can you share the finishing?
