In this article, we will provide some other information about the importance, materials, benefits, installation methods, and common mistakes associated with backsplashes. So, read on to learn more detailed information regarding bathroom backsplashes.

Why is a Backsplash Important in a Bathroom?

A bathroom backsplash plays an important role in protecting your walls from water damage. The backsplash is often made of tile.

When installed correctly, water cannot seep behind tiles and cause mold or mildew growth. This helps to prevent damage such as wall paint bubbling, cracking, or chipping, damp odors, and mold.

The bathroom backsplash can provide a visual focal point in the bathroom and add to the overall aesthetic of the space. It's a great way to add personality to your bathroom. Whether you choose a bold pattern or a neutral tile, a backsplash can tie-in other elements of the room's design.

In addition, a backsplash can help to keep the wall clean by preventing dirt and grime from building up. With so many benefits, it’s no wonder that bathroom backsplashes are becoming increasingly popular.

Previously, the standard height for a backsplash was four inches, just enough for water splashes. However such standards are now considered outdated. It is a great choice if you're aiming for a classical design.

But now, the standard height of a bathroom backsplash typically ranges from eight inches to ceiling height which is usually higher than the kitchen backsplash. However, this can vary depending on the size of the vanity, sink bowl, faucet height, and countertop.


If you go with a taller vanity or vessel sink, the backsplash may need to be higher to accommodate it. Some people opt for a full-height backsplash that runs all the way up the wall.

How to Determine the Right Height of Your Backsplash?

When choosing your backsplash height, there are several factors to consider such as:

  • personal preference,
  • style,
  • design elements,
  • and function. 

For instance, if you have an open-concept bathroom layout without walls separating the shower from the sink area, you might opt for a taller backsplash. This way, the water doesn’t splash out onto other areas of your bathroom.

Additionally, if you are using tiles in your backsplash they should be installed with at least an ⅛-inch expansion gap above any countertop surface or appliance. The gap prevents steam or splashed water from damaging the tiles. 

Ultimately, when deciding on the right height for your bathroom backsplash it is important to consider all these factors as well as how it fits into your overall design plan.

Your backsplash measurement is important to consider when designing the layout of your bathroom, as it determines the height of all other elements in the room, including countertops, cabinets, and lighting fixtures.

In general, the taller the backsplash, the more effective it will be at protecting the wall. However, it is important to consult with a contractor or designer before installing a taller backsplash, as this may impact the overall aesthetics of the room.

How Do I Measure for a Backsplash?

Measuring for a backsplash may seem daunting, but taking accurate measurements is the key to a successful installation.

Before you begin, decide what kind of material you would like to use and check that it will fit with the space available in your bathroom. Take into consideration any trim or molding that may need to be removed before starting the measuring process.

To start, measure the area where the backsplash will be installed. This includes both wall and countertop spaces.

Make sure to take into account any outlets or switches that will need to be cut around and write down your measurements on paper so you don’t make any mistakes.

For walls with uneven surfaces, measure horizontally at both their highest and lowest points then subtract one from the other to get an approximate width. It's important to double-check all measurements before cutting tiles!

Next, determine how many tiles you need for your backsplash by dividing the total linear feet of wall space by the width of each tile plus 1-2 millimeters or 3 - 5 millimeters for spacers or grout lines.

This number is rounded up to give you enough room in case of any mistakes during installation. If there are various tile sizes, calculate each size separately and add them together at the end to get the total number of tiles you need, make sure to add extra tile pieces for the end caps, corner pieces, and bullnose trim if needed.

Before you begin, make sure to measure your space and purchase enough tile for both the backsplash and any trim pieces that you might need. You'll also need to decide on adhesive or mortar for attaching the tile, as well as a grout for finishing off the edges.

When selecting your supplies, choose materials that are suitable for use in wet locations such as bathrooms.

Once you have all of your supplies assembled, begin by preparing the wall surface. Make sure that it is clean and free of debris before proceeding with the installation.

You'll want to apply either adhesive or mortar directly to the wall in an even layer using a trowel. Make sure not to apply too much, otherwise, it could run down the wall when you press the tiles into place. Affix mesh tape atop the mortar.

Next, start pressing each tile into place one at a time. Use a leveler tool if needed to ensure that they are straight and even with one another. This is especially important if you have picked mosaic tiles instead of larger flat ones.

Once all of your tiles are in place, let them settle for 24 hours before applying grout. Grout should be mixed according to package instructions before being applied with a grout float in between each tile gap. Let the grout dry completely before wiping away any excess with damp cloths.

Depending on what type of backsplash material you have chosen, be it ceramic, stone, or glass, or anything else, you may also want to apply some sealant after the grouting has been finished. This will help protect against water damage.

What Are the Different Materials That Can Be Used for a Bathroom Backsplash?

There are many different materials that can be used for a bathroom backsplash, including:

  • tile,
  • glass,
  • metal,
  • and stone.

Each material has its own advantages and disadvantages, so it's important to choose the right one for your needs. 


Tile is a widely available option that comes in a variety of colors and styles.

Some of the options are ceramic tiles, peel-n-stick, and mosaic tiles in different finishes. The popular options are usually a combination of different styles of tile depending on the vibe you would like.

It's easy to clean and maintain, but it can be susceptible to cracking and chipping. But with proper maintenance, it is a great choice since the price range could be adjusted depending on your budget.


Glass is a popular choice for bathroom backsplashes. It's easy to clean and provides a sleek, modern look. However, glass backsplashes can be more expensive than other options.


Stone backsplashes are a beautiful option that adds natural elegance to any bathroom. They're also very durable, but they require more care and maintenance than other materials.

What Are Some Common Mistakes When Installing Bathroom Backsplashes?

People often forget to use mesh tape beneath the tiles to reinforce them and add support as well as to prevent cracks from occurring due to movement.

Not leaving enough space between the countertop and the backsplash is another common mistake; a space of 1/8-inch should be left between them for expansion purposes.

Finally, not cleaning up excess grout can lead to discoloration and staining of tiles over time so it is important to take extra care with this step during installation. Properly sealing both grout and tile after installation can also help avoid water damage or contamination by debris or dirt.

Final Words

Backsplashes can be a fun way to add personality and style to your bathroom. They also serve a practical purpose by protecting your walls from water damage.
