How to fill the space between the dresser and the wall

The gaps between the vanity and the wall fall into one of two categories: a gap between the vanity and the back panel or a gap between the vanity and the side panel. The latter is more common than the former, but the former is more annoying since the back of the vanity must be flush with the wall. With that in mind, let's take a look at how we deal with those annoying gaps.

Filling the space between the vanity and the back wall

When it comes to putting together a dresser, there should be no gaps between it and the back wall. However, gaps may appear if your wall is not perfectly flat. These gaps are not only unsightly, but water splashes can collect between the vanity and the wall, damaging the wood and creating the perfect environment for mold and bacteria.

The gaps between the vanity and the back wall are usually not large and can be easily fixed. Here are three quick fixes.

Seal small gaps

If you only need to fill one or two small spaces, you can use silicone caulk to do so. Silicone caulk comes in clear and white variants, making it a great choice for all bathroom colors.

To fill the gaps you will need a tube of putty and acartridge pistol. Hold gun at a 45 degree angle and apply a small amount of product.

Put on a pair of latex gloves and spread the caulk along the line between the wall and the vanity. Repeat the process if necessary and allow a few minutes for the caulk to dry before using the sink.

Use a thick backsplash

Another easy way to fill a smaller space is with a thicker backsplash. You can choose from a variety of models made of different materials, from wood to glass. Plastic and glass backsplashes are the best choice when you want excellent water resistance.

Whichever type of backsplash you install, remember to seal the edge between it and the vanity with silicone caulk to prevent water from seeping in between.

Use a grab bar

Sometimes there is a gap between the vanity and the back wall because the sink needs a larger space for proper installation. These medium-sized spaces are easily covered with a support bar.

Like a wall panel, the Grab Bar sits above your vanity and sits flush with the wall, giving your bathroom a streamlined look.

Using the same color caulk (or a clear, dry type if you can find the right shade of silicone caulk), affix the rod to the vanity and seal the edge between the rod and the wall with another thin coat of waterproof caulk.

Fill the gap between the vanity and the side panel

While most gaps between a vanity and a back wall are created because the wall is not flat, gaps between a vanity and a side wall can occur for a variety of reasons. For example, the wall may not be flush and you cannot install the vanity flush with the side wall. You may have trouble finding a big enough vanity. Or you can simply place the sink in the center of the bathroom, at some distance from the side wall. Depending on the circumstances, there are several ways to solve the problem.

tile side wall

If you have a small bathroom with a vanity in the corner of the room, it may not be flush with the side wall. This happens because the wall is not level.

You can fix this type of mishap by laying the tile on the wall; It works the same way as a backsplash, but the solution is better suited to the side wall. The trick is to only tile the top of the wall just above the edge of the vanity. This allows the edge of the tile to fill the small gap between the wall and the vanity.

Add a dresser strip

vanitypadding stripThey are an excellent choice for gaps from around a half inch to several inches. These moldings are made of plastic, wood, MDF or vinyl, simply attach to the sides of the cabinet with nails.

Upholstery strips act as a bridge between the vanity and the wall, providing an ideal solution to the awkward gaps that a mismatched vanity can leave.

Add bookshelves or a side cabinet

If you have several inches of space you want to fill, add shelves or a side cabinet. You can go for either one based on the actual space you have.

As a general rule, a custom built shelf is cheaper than a custom built side cabinet. However, if the distance allows you to fit a cabinet, it would give your bathroom a more streamlined look.

Is it okay to have a 2 inch gap between the vanity and the wall?

Having a 2-inch gap between the dresser and the wall is not good. When installing a vanity, you should install it flush against the wall (so items won't fall into the gap) or leave at least a four-inch gap between the wall and the edge of the vanity if you choose a freestanding installation.

How to measure the distance between the bathroom vanity and the wall

Measuring the distance between the bathroom cabinet and the wall is not complicated. All you need is a tape measure and a sheet of paper.

Most vanities with a built-in sink already have the sink attached to code.

2. Measure the distance between the dresser and the wall

Using the measurements above, position your vanity so the center of the sink is at least 15 inches from any wall.

Measure the distance between the wall and the dresser with your tape measure. Record the distance on a piece of paper. If the gap is ¼ inch or less, you can use caulk to close it. Alternatively, you can try the above methods to fill a larger space.
