Standard Bathroom Vanity Sizes: Which One Is Perfect For You?

When decorating a bathroom, the first thing that comes to mind is vanity size. If you are now wondering, “What is the right vanity size for my bathroom?”, the answer depends on a few factors. Such as the size of your bathroom, the number of users, useful storage and how much space can be left for movement.

How to correctly measure the size of the vanity?

If you don't measure properly before you go shopping for a vanity, you might end up with a vanity with a great design… but it just won't fit.
So, taking proper measurements is the basic step of the whole process.

Step 1: Measure the Total Bathroom Space

You also need to know the length of the wall where you want to place the vanity. Vanities are usually available between 24"–72". So you need to understand how much space is free in your place.

Step 2: How much space is needed between the wall and the vanity?

If you are looking for how much  space should I leave between a vanity and a wall then the ideal is:

• Leave at least 18"-20" of space between the wall and the vanity
• Keep at least 30" between toilet and vanity
• It is also important to keep the clearance of the door, so that there is no problem in opening it
  

If you don't keep this clearance, your bathroom will look congested and messy. And the use will also be uncomfortable.

Step 3: Measure the Sink and Plumbing Fixture

You will decide whether your plumbing is a centred sink or an offset sink. Where your drain and water line exits is critical for vanity fittings.

Step 4: Adjust Vanity Mirror and Light Size

Many people make the mistake of just sizing the vanity and forgetting the mirror and lights. But if you don’t know how to choose the right size vanity mirror and vanity lights,

• The mirror should be 1-2 inches smaller than the vanity
• The light should be in the center position of the mirror or can be mounted on top
•   In case of wall-mounted light or sconces, it is better to put it on both sides of the mirror

Single sink vs. Double Sink – Which one to choose for your bathroom?

There's another significant decision to make when choosing a vanity size: one sink or two?
This decision depends not only on the design, but also on the use of your bathroom, the number of family members and the space.

If the bathroom is small, Single Sink is best

A single sink vanity is perfect for a small master bath or guest bathroom.
This way you can have a stylish setup in less space. Also, get a good space next to the sink—you can keep your toothbrush, skincare, hair tools neatly organized there.

Another advantage is that the installation cost is very low. Plumbing is also straightforward.
This topper is more common in many apartments or older-style homes in Florida.

But there's only one problem—if multiple people want to use the bathroom together, the single sink gets a little jammed.

Double Sink – When the space is big, the convenience is double

If there is enough space in a large master bathroom, a double sink vanity is more practical. Two people can stand together and be fresh. No one will occupy anyone's space. This setup is very popular in new build houses in Florida.

But yes, there should be enough space. Because double sync means at least 60"–72" in size is needed.  And since two sinks have to be installed, plumbing costs and installation time may increase a bit. However, it is a golden option for people who want hassle-free daily routine and privacy.

The layout of your room will dictate which one is best for you

In areas like Lake Park, Florida, housing types vary—some live in older condos, others in newer style single-story homes. If the space is small or you believe in a minimalist look, a single sink is enough.

And if you have a slightly larger floor plan, or you want a future-ready design, a double sink will make your morning routine a lot easier.
