There are a few reasons why kitchen cabinet doors may not touch the floor:
Aesthetic Considerations: Leaving a small gap between the cabinet doors and the floor is often done for visual purposes. It creates a sense of openness and can make the space feel less crowded. Additionally, having a small gap can provide a visual break between the cabinets and the floor, making the cabinets appear more distinct.
Ease of Cleaning: By keeping the cabinet doors slightly elevated from the floor, it becomes easier to clean the floor underneath them. Without a gap, dirt, dust, and debris could accumulate at the bottom edge of the doors, making it difficult to clean properly.
Preventing Damage: Floors in kitchens are prone to moisture and spills, and having cabinet doors touch the floor can make them more susceptible to damage. Moisture, water spills, and mopping can cause the bottom edges of the doors to swell or warp over time. By keeping them slightly raised, the doors are protected from potential water damage.
Accommodating Uneven Floors: Floors in houses are rarely perfectly level, and there may be variations or slight slopes in the floor surface. Leaving a small gap between the cabinet doors and the floor allows for adjustments to accommodate any unevenness. It ensures that the doors can swing open and close smoothly without scraping or dragging against the floor.
It's important to note that not all kitchen cabinets have a gap between the doors and the floor. Some cabinets may have doors that extend all the way to the floor, depending on the design and preferences of the homeowner or the cabinet manufacturer.
