Backsplashes serve both functional and aesthetic purposes in kitchens and bathrooms. A properly installed backsplash protects walls from water damage, splatters, and stains. It also adds visual interest and ties the countertops and cabinets together. When designing your backsplash, an important decision is whether you want the tiles to sit on top of the countertop or underneath it. There are pros and cons to both approaches.
Sitting On Top of the Countertop
Having the backsplash tile sit on top of the countertop is the more common installation method. Here are some of the benefits:
Aesthetics
Sitting atop the countertop creates a clean, seamless look, with the backsplash flowing smoothly from the wall to the countertop edge. This showcases the backsplash as a decorative focal point.
Easier Cleaning
With no crevice between the countertop and backsplash, there is nowhere for grime to build up. Food particles and spills can be wiped directly from the countertop to the backsplash and vice versa.
Flexibility
Installing the backsplash on top allows you to easily change it later. The countertop won’t have to be removed. New tile can be applied over the existing backsplash.
Moisture Protection
Having the backsplash overlay the countertop prevents water from getting underneath and potentially damaging the countertop substrate or cabinetry. It provides full splash protection.
Sitting Underneath the Countertop
Installing backsplash tile underneath the countertop edge has some advantages too:
Smooth Transitions
This creates very smooth, often imperceptible transitions between surfaces. The countertop looks like one continuous surface flowing to the wall.
Minimal Grout Lines
With no vertical grout line between the backsplash and countertop, the installation looks cleaner and more streamlined.
Enhanced Durability
The countertop edge protects and strengthens the top edge of the backsplash. It prevents cracking, chipping or damage from impacts.
Work Surface Continuity
No lip or edge allows uninterrupted workspace when wall cabinets are installed right above countertops. This can increase functional surface area.
Factors to Consider
When deciding whether your backsplash should sit on top of or underneath the countertop, there are a few factors to take into account:
- Countertop material – Materials like granite, quartz, laminate, and solid surface can handle an overlay. Tile or wood may be too fragile.
- Countertop thickness – Thicker countertops like granite allow for a built-up edge that can protect an underlying backsplash.
- Grout concerns – If grout lines on top of the countertop would bother you, go for an underneath installation.
- Planned use – If maximizing workspace is important, underneath may work better. If showcasing the backsplash, on top is likely preferable.
- Appliances and fixtures – Will backsplash sit underneath a stove backguard or sink? This may dictate one option over the other.
Best Practices for Installation
Whichever option you choose, proper installation is key:
- The backsplash should be securely adhered to the wall with thinset mortar. Joints should be grouted for strength.
- Silicone caulk should seal all joints between the backsplash and countertop or other surfaces.
- The bottom edge should rest on a solid, supportive surface like a ledger board or countertop substrate.
- Gaps for expansions and contractions should be left at corners, areas where backsplash meets other materials, cuts, and around plumbing fixtures and outlets.
Conclusion
There are good reasons for installing backsplash tile either on top of or underneath the countertop edge. Consider the pros and cons, your goals, and your kitchen or bathroom details. Proper installation is key to create a functional, attractive area free of moisture damage or cracks. With attention to detail, your backsplash can beautifully accent your space, regardless of which approach you take.
Frequently Asked Questions
Should my backsplash sit on top of my countertop or underneath it?
There is no universally right or wrong option. Sitting on top creates a seamless look and is easier to clean but can leave the countertop vulnerable if not sealed well. Sitting underneath minimizes grout lines for a streamlined appearance and offers enhanced durability but joints must be caulked well. Assess your goals, countertop material, and planned use.
What are the benefits to having backsplash on top of the countertop?
Benefits include easier cleaning, flexibility to change it later, protecting the countertop from moisture damage, and showcasing it as a decorative focal point.
What are the benefits to having backsplash underneath the countertop?
Benefits include smooth, streamlined transitions between surfaces, less visible grout lines, increased workspace when wall cabinets are above, and added durability from the countertop edge.
Should I be concerned about moisture getting underneath the countertop?
Proper caulking and sealing is essential to prevent water ingress if backsplash sits underneath. Use a flexible silicone caulk and ensure you have good adhesion where the backsplash meets the countertop.
How can I get a seamless transition between countertop and backsplash?
Whether on top or underneath, use caulk that matches the countertop color. A carefully cut countertop that tightly fits to the backsplash will also minimize visible seams. Good installation is key.
What kind of countertop can have backsplash installed on top?
Granite, quartz, solid surfaces, laminate, and some tiles work well. Natural stone or ceramic tiles are often too fragile and prone to cracking or chipping on countertop edges.
