Most gas grills arrive as a finished object on wheels. Broilmaster sells something else. The P3SX is a grill head: lid, casting, burner and grids. Nothing underneath, and nothing to stand it on.
Cart, post and side shelf sit on the brand’s own page as accessories. The buyer chooses the furniture afterwards. That is an unusual way to spend around $1,376.41. We recorded that price at Amazon in July 2026.
So this review has one job. Work out what the money buys, given that it does not buy a whole grill.

First Impressions of the Broilmaster P3SX
The casting is the first thing that registers. Heavy-duty cast aluminum has a dull, dense sound when the lid closes. It does not ring like sheet metal. Set the head on a workbench and it sits there like a tool.
Assembly runs off a parts diagram, not a numbered picture strip. The burner drops in and gets a hold-down bolt. A wind deflector, a collector box and the ignitor wire follow. Then the control panel goes on, and a heat indicator sits in the lid.
Then the box stops. There is no cart in it, no post, no shelf. Until one is chosen and paid for, this is a grill with nowhere to be. That is the design, not an oversight.
First cook, and the smoker shutter is the surprise. Open, it behaves like a strong gas grill and sears hard. Pull the lever and stainless blinds slide between flame and food. The same box then roasts a chicken slowly, skin colored rather than scorched.
Key Features of the Broilmaster P3SX
Broilmaster puts almost everything it sells as an option onto the P3SX as standard. The brochure calls it every stainless option already checked. That is what separates this head from the plainer P3X beside it.
- Bow Tie burner, 40,000 BTU: One patented stainless burner spreads fire corner to corner. Separate left and right controls sit on it, so half the box can idle. Broilmaster claims uniform output at any setting.
- 695 square inches of total cooking area: That is the published total for the 3-series head. It counts the folding rack overhead, not only the grids. The sibling P4X publishes 473 square inches, so this is the roomier of the two.
- Stainless steel: Stainless runs through the grids, griddle, smoker shutter, Retract-A-Rack and control panel. The burner is stainless too. Broilmaster names no grade for any of it.
- Adjustable-Height Cooking Grates: The multi-level grids are a two-piece set on 5/16-inch bars. They lift and drop to change how far the food sits from the flame. On P3X-series heads the grids take three levels.
- Stainless steel smoker shutter: A single lever shutters the fire without touching the food. Closed, the grill turns into an indirect cooker for roasting and smoking. It is standard here and optional on the P3X.
- Stainless steel griddle: The griddle drops in where a cooking grid would go. Bacon, eggs and anything small enough to fall through stop being a problem. It carries the same lifetime rust-through cover as the grids.
- Flare Buster ceramic flavor enhancers: Drippings land on ceramic instead of on hot steel. Fat vaporizes into smoke instead of pooling into flame. The burner stays cleaner because less reaches it.
- Electric Igniter: The ignitor runs on a single AA alkaline battery behind its knob. There is no cord and no piezo click. A dead cell is the first thing Broilmaster’s own troubleshooting table blames.
- Made in USA: Empire Comfort Systems builds these in Belleville, Illinois. The Amazon listing carries the claim as a headline bullet. It is part of why the grill is priced where it is.
One burner is the headline that reads badly and cooks well. Rivals at this money advertise four tubes and a sear station. Broilmaster publishes a single Bow Tie burner and puts two knobs on it, left and right. A bow tie is a shape here, not a marketing word.
Do the arithmetic on the published pair and the picture changes. Spread 40,000 BTU across 695 square inches. That lands near 58 for each square inch. Fire per square inch is what sears, and this lid holds heat.
Two knobs on one burner is a narrower kind of control than four tubes. You get a hot side and a slow side, and that is it. Anyone who wants three zones will be moving food instead of turning dials.
The shutter is what makes the range unusual. Open, you get a hot box with two zones. Closed, the blinds turn the same box into a roaster. Broilmaster publishes no figure in degrees, so learn the dial.
Build, handling and durability
Cast aluminum carries the whole build argument, and carries it well. A casting has walls with mass. Warmth stays in the metal instead of passing through. Thin painted steel loses heat every time the wind changes.
The grids match the body. A two-piece stainless set on 5/16-inch bars does not sag or scorch away. Thick bars print the sear marks properly. The control panel, the shutter, the griddle and the folding rack are stainless as well.
Handling, though, belongs to whatever you bolt this to. The head has no wheels, no legs and no footprint of its own. Broilmaster offers carts, patio posts and in-ground posts, and each gives the grill a different life. The mounting decision is the real one, and it happens before the first cook.
Running costs, upkeep and value
Upkeep is mostly the Flare Busters doing their job. Fat lands on ceramic rather than on the burner. A collector box catches what gets past them. Brush the grids hot and the routine is unremarkable.
Parts are the quiet running cost. Broilmaster sells through dealers, so a valve is an order rather than an errand. The upside is that the parts exist and are listed by number.
The warranty is where this grill answers for its price. Lifetime rust-through cover reaches the housing, the grids, the griddle and the burner. The shutter and the Flare Busters get five years. Valves, knobs, ignitors and paint carry one year, which tells you what Broilmaster expects to replace.
Price needs both channels quoted. Our July 2026 capture recorded around $1,376.41 at Amazon. Walmart showed around $1,908.90 for a different configuration. Neither number includes anything to stand the grill on.
Amazon lists a propane head; Walmart’s listing is titled a built-in natural gas grill. Two channels, two configurations, one nameplate. Read the title before reading the price.
Possible Broilmaster P3SX Complaints
- The purchase is not finished when the box lands: A head with no mounting cannot cook, and Broilmaster prices carts, posts and shelves nowhere public. Buyers meet the second bill after committing to the first. Choosing the mounting before ordering the head is the only real defense. Dealers quote the pair together, which is part of why they exist.
- Buying one is harder than it should be: Broilmaster’s site has no cart and routes you to a dealer. In August 2026 the Amazon listing refused to ship to our address. Its rating there sits at 3.5. A local dealer is usually the smoother path, and the one who can service it later.
