Custom Grill Islands in Houston
A custom grill island in Houston is a masonry or steel-framed cabinet built on your patio, finished to match your house and topped with stone that can take sun and heat. Kitchen Remodel Masters builds grill islands as part of our outdoor kitchens and as stand-alone projects, with Eduardo fabricating the countertop in our own shop.
This page covers built-in versus prefab, sizes and layouts, how the island is framed, the finishes, the countertop, grill cutouts, gas, electrical, storage and the timeline. Prices on this page are Houston market ranges from named sources, not Kitchen Remodel Masters quotes.
Built-In vs Prefab Grill Islands
A prefab island is a finished unit shipped on a pallet. A built-in island is framed on your patio to your dimensions.
| Built-in | Prefab | |
|---|---|---|
| Size | Any length, any shape | Catalog sizes, usually 6 to 12 feet straight |
| Finish | Stucco, stone veneer or brick to match the house | Stucco or a few stone looks |
| Countertop | Stone cut to the island | Pre-cut stone or tile |
| Fit | Follows the patio edge, columns and the cover posts | Needs a flat rectangle |
| Cost | Higher | Lower |
In Houston, a basic grill island runs $7,000 to $15,000 and a mid-range outdoor kitchen $15,000 to $30,000, per the sources on our outdoor kitchen cost page. A built-in island is the right call when the patio is covered, the island has to tie into columns or a wall, or the finish has to match brick or stucco on the house.
Grill Island Sizes: 6, 8 and 10 Feet
Length decides what fits. These are the three sizes we build most.
- 6 feet. One 32-inch grill and one access door. Fits a small patio or a townhome yard in the Heights or Montrose.
- 8 feet. A 32 to 36-inch grill, an outdoor fridge and a door or a drawer stack. The most common size in Houston.
- 10 feet. A 36 to 40-inch grill, a side burner or griddle, a fridge, a trash pull-out and storage.
A 6-foot island is about 72 inches long, 29 inches deep and 36 inches high (BBQGuys product data, 2026). We build counters at 36 inches and a raised bar at 42 inches with a 12-inch overhang for stools.
Layouts: Straight, L and U
- Straight. One run along a wall or the patio edge. Easiest gas and electrical, because the lines come straight off the house.
- L-shaped. Two legs in a corner. Cooking on one leg, a bar or prep on the other. The most requested layout for a covered patio.
- U-shaped. Three legs with seating on two sides. Needs about 18 feet of patio width and works best in a 20 by 15-foot space (RTA Outdoor Living, 2026).
Leave 42 to 48 inches of clear walkway behind the grill so the cook and the guests are not in the same lane.
Framing: Steel Studs or Block, Never Wood
Most gas grill makers call for 24 inches of clearance between the grill and combustible material such as lumber, per BuildSteel (2026). A wood-framed island breaks that rule even when the outside is stucco or tile, because the wood is still inside the clearance zone.
Kitchen Remodel Masters frames grill islands two ways:
- Galvanized steel studs with cement board sheathing. Light, fast, and the choice for most patios on a slab.
- Concrete block (CMU) on a footing. Heavier and slower, used for large islands, bar walls and islands that carry a pizza oven.
Both are sheathed in cement board, not plywood or paper-faced drywall.
Finishes: Stucco, Stone Veneer and Brick
- Stucco. Smooth or textured, color-matched to the house. The lowest-cost finish and the most common one in Memorial and Spring Branch.
- Stone veneer. Thin natural or manufactured stone set on the cement board. Ledgestone and stacked stone are the usual picks.
- Brick. Matched to the house brick or a contrasting painted brick. Common in River Oaks and Bellaire where the house is brick.
Every finish gets a weep at the base and vents in the cabinet so heat and any gas can escape.
Grill Island Countertops
The top must take sun, heat and Houston’s 74.7 percent average humidity (NOAA data via Wikipedia). Three materials do:
- Granite. The most common. Handles heat and sun and costs $60 to $100 per square foot outdoors (Pergola Builder Houston 2026). See granite countertops.
- Porcelain. The most UV-stable and needs no sealing. See porcelain countertops.
- Quartzite. Natural stone that holds up under a cover with sealing. See quartzite countertops.
Standard quartz stays indoors. Cambria’s product specification sheet states its quartz is not approved for outdoor use, and most brands say the same because the resin yellows in sun. Our guide to the best countertops for an outdoor kitchen in Houston compares the three with Houston prices. Eduardo templates the island after the framing and finish are done, then cuts the grill, burner and sink openings in the shop.
Grill Cutouts and Insulated Jackets
Every grill ships with a cutout spec: width, depth, and the height of the ledge it rests on. We frame the opening to that spec before the countertop is templated, so the grill drops in with an even reveal.
An insulated jacket is a double-wall stainless sleeve the grill sits in. BBQGuys says a jacket is required when the island is built from combustible materials, which includes wood framing and paper-faced board. On a steel or block island sheathed in cement board, the grill manual decides, and many makers still call for one. We read the manual for your grill before framing and build the ledge the jacket needs.
Gas vs Propane
- Natural gas. A new line from the house meter is a permitted plumbing job in the City of Houston. The grill never runs out and the island needs no tank space.
- Propane. No line, but the tank sits in a vented cabinet inside the island and has to be swapped.
Grills are sold for one fuel, and most cannot be converted, so this is decided before the grill is ordered.
Electrical for Fridge, Lights and Ignition
An outdoor fridge, ice maker, under-counter lights, a rotisserie motor and grill ignition all need power. Outdoor outlets are GFCI-protected with in-use covers, and the fridge gets its own circuit. Electrical work needs a City of Houston permit, and the City requires a licensed electrical contractor to pull it. The Houston Permitting Center residential plan review page lists what needs a permit; cosmetic finishes do not.
Storage Doors and Drawers
Stainless access doors go under the grill for the gas valve and under a sink for plumbing. Drawer stacks hold tools, a trash pull-out keeps the bin out of sight, and a paper-towel holder and warming drawer are common add-ons. We size door openings before the cement board goes on so the stainless frames sit flush with the finish.
Timeline
Most Kitchen Remodel Masters grill islands take 1 to 2 weeks on site:
- Layout, framing and cement board.
- Gas and electrical rough-in and inspection.
- Stucco, stone or brick.
- Countertop template, fabrication in our shop, and installation.
- Grill, doors, fridge and final hookups.
Add a week when a new gas line or a long trench for electrical is needed. Our outdoor kitchen project on West 42nd Street shows a finished island.

Frequently Asked Questions
What is the difference between a built-in grill island and a prefab island?
A built-in island is framed on site from steel studs or concrete block, finished in stucco, stone or brick, and topped with stone cut to fit. A prefab island arrives as a finished unit on a pallet. Built-in costs more but matches the house, fits odd patio shapes and can be any size. Prefab is faster and cheaper but limited to catalog sizes and finishes.
How big should a grill island be?
A 6-foot island fits a 32-inch grill and one door. An 8-foot island fits a 32 to 36-inch grill, a fridge and a door. A 10-foot island fits a 36 to 40-inch grill, a side burner, a fridge and storage. A U-shaped island needs about 18 feet of patio width and works best in a 20 by 15-foot space, per RTA Outdoor Living (2026).
Can a grill island be framed with wood?
No. Most gas grill makers call for 24 inches of clearance to combustible material such as lumber, per BuildSteel (2026). A wood frame inside the island sits within that zone even if the outside is stucco or tile. Kitchen Remodel Masters frames with galvanized steel studs or concrete block and sheathes with cement board.
What is an insulated grill jacket and do I need one?
An insulated jacket is a double-wall stainless sleeve the grill drops into. BBQGuys says one is needed whenever the island is built with combustible materials such as wood framing or paper-faced board. With a steel-stud or block island sheathed in cement board, the grill manual decides. Many grill makers still call for one, so we check the manual for your grill before we frame.
What countertop works on a grill island in Houston?
Granite, porcelain or quartzite. Granite handles heat and sun and costs $60 to $100 per square foot outdoors (Pergola Builder Houston 2026). Porcelain is the most UV-stable and needs no sealing. Standard quartz is not approved for outdoor use; Cambria's product specification sheet says so and most brands agree, because the resin yellows in sun.
Natural gas or propane for a grill island?
Natural gas if the house already has gas. A new gas line is a permitted job in the City of Houston and the grill never runs out. Propane needs no line but the tank lives inside the island behind a vented door and has to be swapped. Grills are sold for one fuel or the other, so this is decided before the grill is ordered.
Does a grill island need electrical?
Usually yes. An outdoor fridge, ice maker, lights, rotisserie motor and ignition all need power. Outdoor outlets must be GFCI-protected and weather-covered, and a fridge should be on its own circuit. Electrical work needs a City of Houston permit, and the City requires a licensed electrical contractor to pull it.
How long does a custom grill island take to build?
Most Kitchen Remodel Masters grill islands take 1 to 2 weeks on site: framing and sheathing, gas and electrical rough-in, stucco or stone, then Eduardo templates and sets the stone top and the grill and doors go in. Add a week when a new gas line or a long electrical run is needed.
