Shape drives the price of a BBQ island more than length does. Answer twelve questions and this calculator gives you a range for Santee, the line items behind it, and a note if your spec has grown past what a typical island of that shape costs.
A BBQ island is the smallest useful version of an outdoor kitchen: a grill, some counter, somewhere to put things down, and usually somewhere to sit. It is also the project where the shape decision costs the most money — every corner means more block cuts, more veneer returns and a countertop seam that has to be mitred and matched. This calculator prices shape, length, grill and finish separately, against the bands published for this market.
Per foot, a straight run is the cheapest island you can build. An L adds about 8% and a U about 16%. If the budget is tight, a longer straight island almost always buys more usable counter than a shorter L for the same money.
Published figures run from $5,000–$10,000 for a small straight island with a grill only, to $10,000–$18,000 for a mid-size one with storage and counter space, to $25,000–$45,000 or more for a U-shape with multiple appliances.
The single largest item that is not masonry. A compact 26-inch built-in and a 42-inch luxury unit are five times apart in price and sit in the same hole in the block.
Stucco, tile, stone veneer, brick or porcelain panel — roughly a three-times spread in labour on identical structure underneath.
A flush overhang is the cheap way to seat people. A raised second tier is really a short block wall plus its own slab, which is why it costs about twice as much — and why it is the thing that hides the working side of the counter from anyone sitting down.
An existing slab or paver patio costs nothing. Lawn or bare soil needs a pad, and the pad has to cure before block goes up, which puts it on the critical path.
This calculator works from the 2026 cost figures published for Santee and East County San Diego. What it cannot see is your slab, the capacity of your gas meter, what is under the old patio, or how a crew would get block and a stone slab into your back yard — and those are exactly the things that decide a real price. We will come out, measure, and give you a written scope with no pressure attached.

It depends on what the second leg is for. An L earns its money when the extra leg becomes prep space or seating that a straight run could not offer — cooking on one leg and serving on the other is genuinely better than doing both in one line. It is poor value when the second leg is just more counter. Per foot, a straight island is the cheapest counter you can build.
For the masonry alone, often not. For the utilities, usually yes: the City of Santee requires a plumbing permit for new gas piping and an electrical permit for new circuits. An island with a propane tank inside it and no electrical typically avoids both. Confirm your own project with Santee Planning & Building, because the answer depends on what is being connected rather than on the island itself.
A flush counter is one level, costs about half what a raised tier does, and looks cleaner. It works well when the seating is around a corner from the cooktop. On a straight island where the stools face the grill directly, people do notice the smoke and the spatter — the raised tier is the usual fix, and it also hides the working side of the counter from anyone sitting at it.
About two feet of counter per seat, and around twelve inches of overhang so knees fit under. Anything past about twelve inches of projection needs concealed support under a stone slab. Published figures put a bar seating overhang extension at $1,500–$4,000, which covers the extra slab area, the brackets and — on a raised design — the second course of block.
A masonry island, no — it is built in place on a footing or slab and taken out with a breaker. Modular outdoor-rated cabinetry can be uninstalled and relocated, which is worth weighing if you are not certain you will stay in the house. Everything else being equal, the island is the part that stays; the grill is the part that moves.
