How To Fix a Gap Between Vanity And Wall


how to fix the Gap Between My Vanity And Wall

Vanity cabinets are seeing a huge leap in popularity, and rightfully so. They are incredibly useful and provide a focal point for almost every bathroom design imaginable.

However, their newfound resurgence doesn’t mean that they’re without problems. One of the most common issues deals with a gap between a vanity cabinet and the wall.

A gap between a vanity and a wall can be difficult, but it’s not impossible to work around. There are several ways to make that gap disappear, including adding a backer rod for the gap between the back of the vanity of the wall and using shelving to deal with a gap between the vanity’s side and the wall.

If you were worried about getting a vanity due to the notorious gap issue, knowing your options can help you make the right decision for your bathroom installation. Here’s what you need to know…

Do All Vanities Have Gaps?

Whether or not a vanity will have a gap between walls depends on the build of the vanity as well as the installation you need to do. Most vanities will have gaps. That being said, not all vanities will have gaps and gaps can be prevented through careful planning. Selecting a cabinet that isn’t prone to gaps is a major part of the battle.

How Do Gaps Between Vanities And Walls Occur?

A vanity will have a gap if the actual structure of the vanity has something that pushes the main portion of the cabinet away from the wall. It also can occur if you need a special sink installation procedure that requires space between the vanity and the wall.

Measurements can play a big role in gapping, too. At times, vanity cabinet gapping can also happen due to a measuring error or as a result of not being able to find a cabinet that works with your bathroom measurements.

How To Fix Gaps Between A Vanity And Back Wall

There are two types of gaps that are commonly cited here. There are gaps between the back of the vanity and the adjacent wall, and gaps that can occur on the sides of a vanity. Let’s start by talking about how to get rid of the gaps between a vanity and your back wall first…

Use A Bathroom Sealant Tape

The easiest way to fix medium-to-small gaps between walls is to use a bathroom sealant tape to help get rid of small (but noticeable) spaces between a cabinet and the back wall. Using it is simple. Just apply the tape on clean surfaces to lock out moisture and smoothen your vanity’s lining.

Use Caulk And A Backer Rod

Another easy want to ensure that you get medium-sized gaps out of the way is to place a backer rod in the cabinet’s gap. Once the backer rod is in place, use caulk to seal the rod in and help blend the rod in with nearby surroundings.

When using caulk to stop a gap between a vanity and wall, it’s best to try to use color matching caulk to do it. This reduces the chance of having a visually jarring border around your vanity. If you can’t find caulk that matches the cabinetry, using clear-drying caulk is your next best choice.

Caulk Small Gaps Together

If the gap between your vanity and wall is small, then the best way to seal away the gap is to grab some transparent caulk to do it. Smaller gaps won’t need a backer rod to fill things in. To get an extra crisp line, use tape on your walls to prevent smearing.

Like with the backer rod option above, using caulk exclusively as a way to fill in a gap is best done with some color-matching in mind.

Invest In A Thicker Backsplash

One of the easiest ways to make a gap between a vanity and a back wall disappear is to use a backsplash to get rid of the gap. Thicker backsplashes can make gaps appear almost entirely nonexistent while still giving you the look of having a cabinet that’s flush with the wall.

If you are worried about the aesthetics of sealant tape or similar techniques, using a backsplash might be the right way to keep your bathroom’s look perfect. It’s also worth noting that thick-set backsplashes can cover larger gaps than most other solutions out there.

How To Fix Gaps Between A Vanity And A Side Wall

Sometimes, you might end up with a vanity cabinet that leaves you with extra room between one side or another side of your bathroom. This can be visually jarring, but thankfully, there are ways to make good use of that space. Here are some of the best methods to use…

Using Any Of The Typical Methods That Work With A Back Wall Can Help

If you’re dealing with a small gap between your vanity and one corner of your bathroom’s wall, then you can usually use any of the methods used for back walls with a fair expectation of seeing good results.

Add A Smaller Side Cabinet To Cover The Gap

With gaps that take place between a vanity and a wall corner, there’s a good chance that you may have a much larger gap than what you’d expect from a back wall gap. If you are stuck with several inches of space, you should consider adding a small pull-out cabinet to bridge the gap.

The trick to making this work is to try to make the top of your vanity match the top of the side cabinet. It’s possible to make your own cabinet addition that fits with most vanity styles. However, it might require a little woodworking knowledge and craftiness in order to make it work.

Use Shelving As A Stopgap

If getting a full cabinet is too much for you, another option would be to install additional open shelving to give the gap an additional purpose in your bathroom. The shelving alone will add extra storage space.

This option will require you to get a small cut of countertop that matches your vanity’s top to work. After all, you will need to “lengthen” your vanity’s counter to make the shelving look neat.

Or, Just Add A Trash Can

Another good option for larger gaps is to use the space as a place to put your bathroom bin. After all, garbage cans are a necessity for any bathroom layout. In many situations, that gap can offer a perfectly sized nook for it.

Our Final Take

Gaps between vanities and walls are commonplace, but that doesn’t mean they should dissuade you from getting the vanity that you want. There are plenty of ways to fill in those gaps based on the size of the gap and your vanity’s position in your bathroom.

The bottom line is that you always have options when it comes to creating that smooth, clean, and effortlessly chic look that a gap-free bathroom vanity has to offer.

Sure, some methods may require additional building or expensive materials, but the truth is that it’s always doable. It just takes a little creativity and effort.
