When planning a kitchen or bathroom remodel, one common question that arises is: should backsplash go on side walls too, or just behind the countertop and stove?
While the backsplash is often seen as a functional element protecting the wall from moisture and spills, it also plays a key role in defining the aesthetics of your space. At SF Marble and Granite, we’ve helped hundreds of homeowners in Lowell and nearby areas navigate backsplash design decisions—always focusing on function, style, and long-term satisfaction.
In this guide, we’ll break down the practical, aesthetic, and design considerations of adding backsplash to side walls, helping you make the right call for your space.
What Is a Side Wall Backsplash?
Before diving into whether you should install it, let’s clarify: the side wall backsplash refers to the portion of wall adjacent to countertops, especially those next to appliances or near open wall ends. Unlike the main backsplash—typically behind the sink and cooktop—the side wall backsplash extends the tile or stone to the lateral wall area, often forming an L-shape.
Depending on layout, this can cover:
One side of the counter against a wall
An exposed cabinet end wall
A short return wall
Bathroom side walls near vanities
The Benefits of Extending Backsplash to Side Walls
1. More Protection From Splashes and Grease
One of the main reasons for backsplash installation is protection. Side walls, especially near stoves or sinks, are still vulnerable to:
Grease splatters
Water spots
Food stains
Adding backsplash to side walls offers complete coverage, reducing future repainting or wall repairs.
2. Creates a Finished, High-End Look
A partial backsplash can look unfinished—especially in kitchens where only the back wall has tile. Extending the material onto side walls adds:
Visual balance
A custom, seamless appearance
More depth and design cohesion
If you’re using luxury materials like marble or granite, full-wrap backsplash designs elevate the sophistication of the space.
3. Better Resale Appeal
Many modern buyers are drawn to well-finished kitchens and bathrooms, and side wall backsplash installations add that extra “designer” touch. It subtly communicates that attention to detail and high-quality materials were prioritized.
When Should You Install Backsplash on Side Walls?
At SF Marble and Granite, our backsplash installation experts always begin with a layout consultation. Here are the situations where adding backsplash on side walls makes the most sense:
Your countertop ends against a wall.
In this case, you’ll often see food or liquid splashes accumulate on that bare wall. A side wall backsplash provides practical protection.
You’re using natural stone or full-height backsplash.
Materials like granite, quartz, or marble are often cut to size. Extending to the side wall ensures visual flow and material consistency.
You want a luxury kitchen or bathroom look.
Whether you're aiming for a spa-like bath or a chef-inspired kitchen, extending backsplash on adjacent walls creates that full-wrap aesthetic you see in high-end homes.
When You Might Skip the Side Wall Backsplash
There are some layouts where a side wall backsplash isn’t necessary—or can even feel out of place.
If your cabinets go wall-to-wall
In tight galley kitchens or bathrooms, the cabinet may end flush with the wall, leaving no visible surface to tile.
If budget is tight
Every extra square foot of tile, labor, and grout adds cost. If you’re on a strict budget, focus on high-impact zones first (like behind the stove and sink) and consider adding side backsplash later.
If your backsplash design is decorative-only
Some homeowners opt for a statement tile feature rather than a functional backsplash. In such cases, extending to side walls might disrupt the focal design.

Expert Tips
If your backsplash stops halfway up a side wall, a finished edge trim adds a polished touch. These small details can make a big difference in the final appearance.
Trims can be:
Bullnose tiles
Schluter metal trims
Coordinating tile caps
Our backsplash installation team at SF Marble and Granite always recommends a trim when installing side wall extensions.
