This blog post will provide you with all of the information that you need to know about how to build a custom bathroom vanity. We’ll discuss what materials you’ll need, how to measure everything out properly, and even show pictures of some completed vanities so that you know just what it looks like when it’s done!

Make no mistake about it the Pros make this magazine quality look easy. But the reality is that it’s not.

If you are looking for a quick, simple bathroom vanity then this option might not be right for you. This process can be done in less than one day. With the right tools and knowledge you can save quite a bit of money over buying something pre-made. However, keep in mind that if any mistakes are made during measuring or cutting there won’t be many options to fix them!

For those who want more flexibility with their vanities but still don’t want all of the work involved in building out custom cabinets using plywood; prefab vanities may work well for you. They usually consist of premade carcasses (the box part) which would allow you to make some changes like adding drawers or changing around where everything.

Here we go,

How to build a Custom Bathroom Vanity

Measure twice, cut once.

That is the phrase I always use when building anything.

Be sure to account for any items you might want added (towel bars, soap dispensers, etc.) in your measurements.

To make this process even easier we’ll be using tools from our very own DeWalt Oscillating Tool! Oh yes that’s right; these are some of my favorite tools – and they’re not just because they came free with my tool set either! These work great for projects like this one where you need something compact but still powerful enough do the job. And having all of them in one box is so much better than trying to lug around multiple heavy ones! Now let’s get started!

Determine how high you want the finished counter top from the floor. Usually 36 inches is a comfortable height

Determine the depth you want the box from the wall, I usually use 21 inches.

Determine the foot style and height.

Subtract foot height (minus attachment required overlay or underneath) from overall height

Minus countertop thickness from above step ( rough height)

Cut bottom (depth measurement x length of vanity)

Cut sides (depth measurement x rough height measurement

GLUE and Staple side on top of bottom

Cut back support out of 6 in wide material, get this measurement by measuring between the 2 side at the bottom where it is attached for precise measurement

Glue and Pin nail between the side on the top back

Now it should stand by itself.

Attach feet now, trim out all decorative skirting between the feet and sides , glue to the exposed plywood edge on the bottom with out going over the side panels and pin nail.

Determine door and drawer placement, out of 1 1/2 stock material, measure and cut the face frame

Pocket hole screw this together for the tightest fit.

Only pin nail this on for now in a couple places

any complete uprights will need a solid divider ( square this up)

To make the drawer box bottoms use 3/4 in material supported by 3/4 inch material cut the height of the drawer box material plus 2 inches. ( Stack these like a bench it will be stronger.

Mark where the drawer box bottoms are on the face frame

Remove face frame pocket hole screw and glue to cover plywood bottoms

Glue and pin nail Face frame back on

Install drawer slides

If you are using undermount soft close slides measure drawer box width 5/8 smaller than your opening, height 2inches smaller than drawer opening height

install drawer box on slide

Install doors

Prep materials


sand again




Install vanity to wall

Install vanity top

Plumbing installation

Install mirror

Mop and enjoy!

Remember to :

Use hardwood material rather than soft wood material .

It’s important that measurements are correct so it fits properly within the space.
