Understanding the Backsplash Void in Corner Cabinet Construction
When embarking on a kitchen or bathroom renovation, one of the most challenging yet rewarding tasks is constructing corner cabinets. These cabinets not only maximize your storage space but also add a touch of elegance to your room. However, a common question that arises during this process is: why do you need to set the backs in to create a void, often referred to as the backsplash void?
What is the Backsplash Void?
The backsplash void, also known as the backsplash space or reveal, is the gap between the back of your cabinet and the wall. It's a common feature in corner cabinet construction, but its purpose might not be immediately apparent. This void is not a design oversight or a sign of poor craftsmanship; instead, it serves several crucial functions.
Why is the Backsplash Void Necessary?
- Plumbing and Electrical Access: The void provides easy access to plumbing and electrical lines behind the cabinet. This is particularly important during installation and any future maintenance or repairs.
- Ventilation: In kitchens, the void allows for proper ventilation of the stove and other appliances. Without this space, heat and moisture could become trapped, leading to mold and other issues.
- Wall Imperfections: Walls are rarely perfectly flat or square. The backsplash void helps to hide any minor imperfections, ensuring a neat and professional finish.
- Backsplash Installation: The void provides the necessary space for installing a backsplash, such as tile or glass, behind the cabinet. This not only protects the wall but also adds a decorative element to your room.
Determining the Size of the Backsplash Void
The size of the backsplash void can vary depending on your specific needs and the layout of your room. However, as a general rule, a void of about 1/2 inch to 1 inch is typically sufficient. This size range provides enough space for access, ventilation, and backsplash installation while minimizing the visual impact on your room.

Creating the Backsplash Void: Step-by-Step
Creating the backsplash void is a simple process that involves a few key steps:
| Step | Action |
|---|---|
| 1 | Measure and mark the desired void size on the back of your cabinet. |
| 2 | Use a jigsaw or router to cut along the marked line, creating the void. |
| 3 | Sand the edges of the void to ensure they are smooth and won't damage the wall or backsplash. |
| 4 | Install the cabinet, ensuring it is level and plumb. The void should be facing the wall. |
Final Thoughts
The backsplash void is a critical aspect of corner cabinet construction that often goes unnoticed. However, understanding its purpose and how to create it can significantly enhance the functionality and aesthetic appeal of your cabinets. So, the next time you're planning a renovation, don't overlook the importance of this crucial detail.
