Do countertops sit directly on cabinets?

Do countertops sit directly on cabinets? This is one of the most common questions homeowners ask when planning a kitchen upgrade. The simple answer is: yes, countertops usually sit on cabinets, but not always directly without preparation or support.

In most modern kitchens, countertops are installed on top of base cabinets with a secure leveling system, adhesive, and sometimes additional support layers like plywood or brackets. The installation method also affects the kitchen countertop cost average, countertop installation charges, and overall durability of your kitchen setup.

At SF Marble and Granite Inc, we help homeowners understand every step of countertop placement so they can make informed decisions for long-lasting results.

How Do Countertops Sit on Cabinets?

When people ask do countertops sit directly on cabinets, they are usually trying to understand the stability and structure of the installation.

In most cases, countertops are placed on:

• Base kitchen cabinets

• Leveling shims (for uneven surfaces)

• Adhesive or silicone layers

• Optional plywood underlayment

Do countertops sit directly on cabinets in all cases?

Not always. While many countertops rest directly on cabinet frames, stone materials like granite or marble often require extra support to prevent cracking or shifting over time.

Heavier materials need proper load distribution to ensure durability and safety.

Standard Countertop Installation Process

Understanding the process helps you estimate the price for countertop installation more accurately.

Step 1: Cabinet inspection and leveling

Before installation, professionals check if cabinets are level and strong enough to support the stone.

Step 2: Dry fitting

Countertops are placed temporarily to check alignment and fit.

Step 3: Support preparation

Depending on material, installers may add:

• Wooden support strips

• Plywood base

• Metal brackets

Step 4: Adhesive application

Silicone or construction adhesive is applied to secure the countertop.

Step 5: Final placement

Countertops are carefully set in place and adjusted for perfect alignment.

Step 6: Sealing and finishing

Edges and seams are sealed for water resistance and durability.
