Custom Outdoor Kitchen Cost in St. Louis: 2026 Price Ranges

Cost by build size

• Grill island only (8-12 linear ft): $8,000–$16,000 — a built-in grill, a run of countertop, storage doors, and a stub gas line.
• Standard kitchen (12-20 linear ft): $18,000–$32,000 — grill, side burner, small refrigerator, sink, and a bar-height counter section.
• Full outdoor living kitchen (20+ linear ft): $35,000–$60,000+ — multiple cooking appliances (grill plus pizza oven or smoker), full bar, refrigeration, and often a covered structure overhead.

What drives cost inside those ranges

Materials

Stucco or manufactured stone veneer over a CMU (concrete masonry unit) frame is the most common St. Louis approach and the most cost-efficient. Natural stone veneer (real limestone, fieldstone) runs 30-60% more than manufactured veneer for a similar look, but holds up better long-term against freeze-thaw spalling. Countertops range from laminate (rare on an outdoor build) to granite ($60-100/sq ft installed) to porcelain slab ($80-150/sq ft installed), which is increasingly preferred in St. Louis for its freeze-thaw and stain resistance.

Appliances

A quality built-in gas grill runs $2,500-$6,000 installed. A wood-fired pizza oven adds $6,000-$15,000 depending on whether it's a prefabricated insert or a fully masonry-built oven. Side burners, warming drawers, and outdoor-rated refrigerators each typically add $800-$2,500.

Utilities & site prep

This is the category homeowners underestimate most. A new gas line run from the meter, sized and permitted correctly, commonly adds $1,500-$4,000 depending on distance and whether trenching hits hardscape that needs to be cut and patched. Electrical for lighting, outlets, and a refrigerator circuit runs $800-$2,500. If the kitchen sits on unimproved ground, grading and a slab or paver base can add $2,000-$6,000 before the masonry even starts.

Covered structures

A pergola or full roof structure over the kitchen — increasingly common in St. Louis for both shade and to protect appliances from weather — typically adds $8,000-$25,000 depending on materials (cedar vs. steel-frame) and whether it's open or fully enclosed.

A realistic line-item example

A 16-linear-foot outdoor kitchen with a built-in grill, side burner, small fridge, granite countertop, and manufactured stone veneer, including a 20-foot gas line run and basic paver base prep, typically prices around $24,000-$29,000 installed in the St. Louis Metro as of 2026. Add a wood-fired pizza oven and that same build moves to roughly $32,000-$40,000.
