When determining the right size vanity for your bathroom, there are several questions you need to answer to feel confident in your choice. If you can answer these questions we put together first, then you can move on to choosing the look and feel of your vanity to make sure it effortlessly fits within your bathroom’s space.

Vanity Sizing Questions to Consider

  • Where’s the plumbing located?
  • Will the plumbing connections be easy or will they obstruct the full use of the vanity?
  • How much space do you have available?
  • Is your bathroom narrow, wide or open?
  • What are all the space restrictions that you need to consider?

If you are aware of potential restrictions to your bathroom layout, you can make sure that your vanity will be the most functional if you do.

Once you have been able to answer our initial spacing questions, then follow these sizing steps for finding the right vanity for your bathroom. Determining the dimensions you need first will eliminate the fear that the vanity you liked the look of might not fit. By following our questions in our suggested order, you will be able to have a comfortable fitting vanity for your bathroom.

Vanity Width Sizing Tips

Start with the vanity’s width. This is the easiest dimension to start with because this will determine whether or not your vanity will fit. This typically determines whether or not you can get a single or double vanity.

Make sure the vanity width will fit well into the bathroom. Use the plumbing to help guide where you will put the vanity. Don’t forget that the vanity top is typically ½ inch to 1 inch more on either side of the cabinet width.

A single vanity is typically under 48 inches wide and 36 inches is very common. Single vanities are great for smaller bathrooms. You can always put two single vanities next to each other to save space. For very small bathrooms, consider a wall hung vanity.

A double vanity is commonly 60 inches or 72 inches wide. A 72 inch vanity is better for more counter space and storage space.

Vanity Height Sizing Tips

Once you determine how wide your vanity can be, it is best to determine the height. This is extremely important to make sure that you are comfortable when you are using your vanity. You don’t want your vanity too low or too high.

Use these simple considerations when determining what height will be the most comfortable and the most practical.

Master Bathroom Vanity

36 inches high - This is the standard for kitchen cabinets. It’s more comfortable than the original 30 inch standard for bathrooms.

Guest Bathroom Vanity

32 to 34 inches high - This is a comfortable height for guest bathrooms that may be used by both children and adults. This is a great compromise for a bathroom that is not used on a daily basis but accommodates most heights.

Kid's Bathroom Vanity

30 inches high - This used to be the standard height for bathroom vanities in the past. So this is a little low for adults to use, but makes it more manageable for kids as they grow up and get taller. You can also consider a vanity with a pull out step for your kids as well.

Vanity Depth Sizing Tips

Determine the depth measurement as your last so that you can see what your overall vanity options exist. The depth is the most necessary for narrow bathrooms.

When determining what depth you can fit, make sure to consider the following:

  • The vanity will not obstruct doorways or entryways
  • The vanity drawers and doors can open easily
  • Other storage, shower doors, etc are easily accessible
  • Drawer pulls and knobs won’t obstruct anything
  • You have enough clear floor space - for more info check out our bathroom floor plan guide

Now that you know what size vanity you need, it’s time to go shop.
