Let me show you step by step this DIY Floating Wood vanity.

So I am soooooo close to being done with my major project of the last year. You may remember me talking about this huge project of turning an oversized guest bathroom into a smaller bathroom and third floor laundry room.

Having the laundry on the same floor as the bedrooms has been a game changer for me. Plus it has stretched my DIY skills by teaching me how to frame, drywall and mud.

The new bathroom size is 7″ x 11″ and it was 11″ x 11″. So I had the option of doing a larger shower and smaller vanity or larger vanity and smaller shower. There was a big difference in size as far as the shower was concerned. It was either a 36″ or 48″ pan.

An extra 12″ of room is huge in a shower. Plus I didn’t want to pour a custom shower pan, my DIY skills were already stretched enough . So I opted for a larger shower and a small vanity area.

Building a Floating Wood Vanity Step-By-Step

So I framed in a wall for the shower surround to go which only gave me 29″ of space for a vanity.

All the vanities I found were like 24″ or 28″ and I knew the extra inches on the sides would bug me plus I wanted to have as large of a vanity area as possible.

So I decided to build a floating vanity like you see in higher end hotels. It was very simple an super inexpensive.

Supplies you’ll need:

Step By Step guide

Step 1 – Measure the area

Start by measuring the width of the sink area. I decided to go a little deeper than standard vanities and went 25″ for the depth (plus the face frame made it 26 1/2″).

Using a table saw I cut my piece of plywood to fit that area.

Step 2 – The Face Frame

Next I grabbed a pine 2″ x 8″ and ripped it down to 6″ for the face frame on the vanity. I didn’t worry that it is pine and birch mixed.

It turned out fabulous once stained.

Step 3 – Sand it

Using the sink template (I purchased this stock sink from Lowes) and a jigsaw I cut out the circle for my sink.

Sand with 150 grit sandpaper with an orbital sander to give both pieces of wood a nice smooth finish ready for stain.

Step 4 – Treat the Wood

I used a pre-wood conditioner on the pine board since it is a soft wood. Then I applied my stain. I used Minwax Dark Walnut.

The pine board needed a couple of coats to get it to match the birch piece. I let it dry overnight.

Step 5 – Apply Finishes

With an old t-shirt scrap I applied the General Finishes Top Coat.

Let it dry 24 hours between coats and then lightly sand in between coats with 400 grit sandpaper. I gave it 4 coats.

Step 6 – Cut out rest of Pieces

Then I cut out (3) 2″ x 4″ pieces. One board was the width of your vanity top.

Then I cut two more 1 1/2″ less than my vanity width.

I drilled two pocketholes on each end of the last two boards I cut.

Step 7 – Attach the Boards

I found the studs and then used 2 1/2″ screws to screw the back board in place.

Then I used pocketholes screws to attach the two boards to the back piece. I marked the studs on the side wall and used 2 1/2″ wood screws to secure those to the studs.

This gave me a very sturdy base for my vanity top.

Step 8 – Nail the Vanity to the Frame

At this point I nailed my vanity top to the frame but I could have added pocketholes previously to my 2 x 4 boards and attached it that way.

Either works. But nails did require some touch up stain and top coat.

Step 9 – Add the Face Frame

To add the face frame I used 2 1/2″ Kreg screws into the side 2″ x 4″ supports to attach to the back of the face frame.

Step 10 – Fill the Holes

I used wood filler to touch up the holes.

Step 11 – Seal it

Seal the sink with caulk (I opted for white to match the sink).

Then I sealed the area where the vanity top meets the wall with clear silicone caulk.

Step 12 – Optional – The Pipes

I decided to leave the pipes exposed. Since they were white PVC pipes I taped off the whole area and used RustOleum Steel Metal on them.

I was reminded why I don’t purchase RustOleum.

I loved the color but I got two defective cans and had to go to the store twice to return them. UGH!

I should have stuck to my trusty Krylon.

I love the way the pipes turned out though.

The color is very authentic to regular pipes as evident by the pipe hand towel bar I made with 3/4″ elbows, 1 1/2″ connectors, 3/4″ flanges and a 6″ pipe.

The vanity area is small but I think it is perfect for a guest bathroom. And I absolutely love the dark wood vanity top paired with the gray tones in the Aquaguard flooring and the white trim.

Oh and here is a SNEAK peek of the mirror I made with all scrap wood so it was totally FREE!  More on that soon!
