DIY - Floating Bathroom Vanity


Update the powder room by DIY-ing a modern floating vanity.

Hello there! I'm back with another project tackled in this little powder room: The vanity. 

The previous project in this room was all about the ceiling treatment, you can check that post right HERE.

As you can see in the picture below, a pedestal sink was what this little bathroom sported. Yep. This sink had been here for more than 20 years. I like pedestal sinks, but after so many years with the same configuration, I was more than ready for change. The feature I like the least about pedestal sinks is the lack of a space or counter around them. 

I wanted my new vanity and more exactly the countertop to be a focal point in this room. I wanted to have a stone counter, and given that this is a small area/vanity, it was OK for me to splurge on quality material.
That's precisely one of the beauties about the renovation of a tiny space! 

Let's take a look at how this floating vanity was built. I promised you that this is a very simple DIY!

THE TOP

Before we dig into the building of the vanity, let's talk about the countertop. I just told you, how I wanted the top to be a focal point on the vanity and bathroom. 

The material that I wanted to top this bathroom floating vanity was marble or granite stone. and that's why I went to a local stone fabricator to find a beautiful stone for my vanity. Here in the DC area, my place to go is Architecture Stones.

If you want to go that same route, let me give you a few tips before you start perusing all those gorgeous slabs:
  • Before removing your old vanity set up, take measurements of that setup. How far from the wall is the faucet. Is it centered? How high is the sink or the old vanity? 
  • Determine the size of your new top.
  • Buy a sink that fits properly your countertop's size.
  • Buy a faucet.
  • Sketch your new top and draw the location of the sink. How many inches do you want your sink from the front edge of the countertop? 
  • Where do you want your faucet? centered? How far from the back do you want the faucet installed? If the faucet comes with separate handles for cold and hot water, how far apart do you want those handles?
  • Bring the new sink and the faucet with you when you go to the stone fabricator.

I did have the sink and the faucet with me when I went to buy the top, but I wasn't prepared with most of those measurements. I thought they just knew it. Nope. Well, maybe they know, but that's your project, you can ask for almost anything and they'll do it for you.

I got my sink centered across the top. The distance from the front edge to the beginning of the sink is three inches. 

The space between the hot water handle / faucet / cold water handle is four inches/each.

The distance from the back to the place where I wanted the faucet installed is two inches. I was glad I took that measurement and had the picture you see below on my phone. Although, I also had to take into consideration the width of the backsplash.

Remember that they accommodate your needs. If you need your counter to be cut in a weird shape, they'll do that for you!


I forgot to take a picture of the plain top with the sink installed, as that's how they gave it to me when I went to pick it up.

The picture below was taken after it was installed in the bathroom.

Let's now build a floating vanity that complements this gorgeous top!


The Materials You'll Need:


The tools: 

           Tape Measure - Drill - Circular Saw - Brad Nailer - Stud Finder - Laser Level


1. MEASURE & MARK 


The first step is to measure and mark how high you want to install that countertop. 

Now, remember that the standard height for bathroom vanity has been 30 - 32 inches up from the floor. Lately, there's been a trend toward higher vanities, they're going now up to 36 inches or customized to a homeowner's personal preference.

I added two inches to the old setup, bringing our new vanity height to 34".

2. FIND & MARK STUDS LOCATION


Draw a level line on the wall at your designated vanity height. 

Then, use a stud finder to locate the studs on the wall. Mark their location.

3. INSTALL A WOODEN CLEAT


A wooden cleat, cut from solid 2 x 4 lumber was used to support the heavy top along the back and sides.
Don't forget to take into consideration the thickness of the slab when installing the cleat.

Make sure you drive the long screws onto the studs on the wall.

I used 3-1/2" screws - two on each stud and I did pre-drills.

On the left side of my installation, I used a couple of toggle bolts to secure it, as I couldn't locate regular studs on the wall.

4. MOUNT THE TOP & CONNECT THE WATER SUPPLY TO THE SINK 


With proper support in place, the next step was installing the top and connecting the water supply. I left this part of the job to the pros.

I was asked if I wanted those pipes to be brought inside the wall, but I declined for two reasons. The price for the installation would've been double and secondly, that back wall is an outside wall. I don't want to worry about pipes freezing in the winter.

I was happy that I had a working vanity with a beautiful quartz Veria Calacatta top and a shiny high arch faucet! But yeah, that bottom part wasn't pretty.

5. INSTALL A FLOATING SHELF


Shelf supports cut from 1x2 lumber were installed on both facing walls, right above the baseboards.

Now, I needed to create a false back wall to help me conceal those pipes. The first step was to add 2 x 4 stoppers to install the baseboard on them.

The location of the pipes was transferred onto the white oak plywood shelf and cut out using a jigsaw.

A 2-1/2" mitered plywood front gives the shelf that clean chunky look that I love!

6. INSTALL A FALSE BACK


Some more pipe concealing was necessary. I used a 1/4" plywood piece cut to fit that back area. Again, I notched out the area for the drain pipe, and 2 x 4 supports were installed in the corners.

NOTE: This board is going to be removable, I'm using Command Strips to set it in place.

7. ADD THE FRONT APRON


The final part is to add the pretty apron.

The gorgeous white oak grain is a statement on its own. I love how this bathroom is starting to look!!

Well, let me tell you that I haven't added a single nail to this entire vanity built. It fits so snuggly that it stays in place without any. :)  I need to remove everything to paint those walls. I've been patching them up, but they're now ready for the paint treatment.

Oh, I also need to install the backsplash, but that's something you're going to see in an upcoming post!

I always like when people add dimensions to their projects. Even if my project is not exactly like theirs, it's easier for me to think about my project when I have those dimensions.

Here are the ones for this little vanity:

Size of counter: 32" x 20" x 1-1/4" thick.
Front apron: 32" x 8" x 3/4"
Shelf: 32" x 15" x 2-1/2" - Height from floor to top of shelf: 11"

I hope this can be helpful for you too!

  2. Wow! this is exactly what I am trying to do in my half-bath and really appreciate all the details with pictures and dimensions. Finding the quartz countertop and sink is a major challenge but with the info you provided, I have new confidence I can make this happen! I have been a long time subscriber and have been collecting your ideas to use in my own house upgrades someday. I wish you continued success!

    1. Hi Maria! Thanks so much for your kind comment and for sticking with me for all these years! ❤️ I understand you when you say it's a major challenge, as I used to feel the same way.
      You have to pay attention to all the measurements when ordering your sink. I first bought one from Home Depot but had to return it because it was too wide (front to back). For the countertop, the stone fabricators are usually very helpful, you just need to know what is it that you want.
      For this type of counter, you're going to be looking at remnant pieces, which are sold at lower prices.
      Good luck with your bath and all those projects in the making!

  3. Hello again,

    I'm confused by the gold p-trap you used. Is the old (pvc) p-trap still in use and hidden behind the vertical wood board? Did the plumber use the gold piece only to connect the sink drain to the existing p-trap?
    Thanks, Maria B.

    1. Hi Maria, No. The old PVC trap was discarded. Since I was going for a modern bath design, I wanted to use that contemporary style p-trap in a gold finish. Somehow the plumber couldn't match all the parts that came with the trap. In the end, he had to use the parts that came with the sink (black PVC) to connect them.
      I didn't bother because I knew that part was going to be hidden with the front apron.
      Now, he had to bring that main pipe coming from the wall a few inches higher for this new trap.
