If you already have a concrete or paver patio, adding a custom outdoor kitchen is more straightforward than starting from scratch — and it can transform a basic slab into a full outdoor living destination. VistaScapes Design & Build regularly adds outdoor kitchens to existing patios throughout Broken Arrow and the Tulsa metro. Here’s what the process looks like and what to expect.
Step 1: Assess Your Existing Patio
Before adding an outdoor kitchen, VistaScapes evaluates your existing patio for two key factors:
- Structural capacity: An outdoor kitchen island built from concrete block or steel stud with stone veneer and granite countertop can weigh 2,000–5,000 pounds. Your existing patio slab needs to be evaluated for adequate thickness (typically 4 inches minimum) and reinforcement. If the slab is inadequate, we can often add footings or thickened slab sections under the kitchen footprint without replacing the entire patio
- Layout and access: We evaluate the existing patio’s dimensions, entry points, and relationship to the house to determine the optimal placement and orientation for the outdoor kitchen
Step 2: Plan Gas, Electrical, and Plumbing Runs
Adding an outdoor kitchen to an existing patio requires running utilities from your home to the kitchen location. For an existing patio, this typically means:
- Gas line: Run in buried conduit or through the exterior wall to the kitchen location. For existing concrete patios, the gas line is typically run along the exterior of the patio or through a saw-cut channel in the slab that’s refilled after installation
- Electrical: A dedicated circuit for outdoor kitchen appliances is run from the home’s electrical panel to the kitchen location, through weatherproof conduit
- Plumbing: If a sink is desired, cold water supply and drain are run to the kitchen location — this is the most complex utility addition and may require opening the slab or running along the surface in a protected chase
Step 3: Kitchen Construction on the Existing Surface
Once utilities are roughed in, VistaScapes builds the outdoor kitchen island on your existing patio surface. We use anchor bolts or adhesive systems to secure the cabinet structure to the existing concrete — ensuring stability without requiring full slab replacement.
The kitchen framing (steel stud with cement board or concrete block), finish coat (stucco, stone veneer, or tile), countertop installation, and appliance installation all proceed the same as for a new patio installation.
Step 4: Patio Expansion (If Needed)
Sometimes adding an outdoor kitchen to an existing patio reveals that the existing surface isn’t large enough to comfortably accommodate both the kitchen and adequate seating and entertaining space. VistaScapes frequently pours or installs a patio extension adjacent to the existing slab to create a complete outdoor living area. New concrete can be poured to match the existing slab elevation, or paver sections can be added for a distinct visual break between old and new surfaces.
What Does It Cost to Add an Outdoor Kitchen to an Existing Patio?
Adding a custom outdoor kitchen to an existing concrete or paver patio in Broken Arrow or Tulsa typically costs $20,000–$55,000, depending on the size and specifications of the kitchen. The existing patio eliminates the cost of a new slab installation, but utility runs (gas, electrical) are still required and add to the project cost.
