We don't quote prices here — Amazon's terms prohibit it and prices change. The button above always shows today's number.
The short version
An oval ceramic, not a round one. The shape lets you run direct and indirect zones simultaneously by piling charcoal on one side — a real cooking advantage no round kamado matches.
Pros & cons
- + True two-zone cooking out of the box.
- + Made in the USA — a real factor for some buyers.
- − The oval shape limits some accessories.
- − Premium pricing, premium weight.
Who should buy it
Cooks who specifically want two-zone cooking and don't mind being slightly off the mainstream ecosystem. See Big Joe III vs Primo XL.

Primo Oval XL 400 — frequently asked questions
Is the Primo Oval XL 400 worth the money?
For buyers who want a serious 28"x18"-class kamado from Primo, yes. It will outlast a typical gas grill by a decade and replaces a smoker, a grill, and a pizza oven in one footprint. Whether it's the best value at its tier depends on what you're comparing it to — see our head-to-head comparisons for the matchup that applies to you.
What size is the Primo Oval XL 400?
The Primo Oval XL 400 is a 28"x18"-class kamado. Cooking-grate diameter is the spec that matters: it dictates how many racks of ribs or how large a brisket fits at one time. The dome and overall footprint are larger than the grate, so always shop by grate inches rather than the manufacturer's published outer dimensions.
Is the Primo Oval XL 400 available on Amazon?
Availability changes constantly — use the Amazon button on this page to see today's listing, current shipping estimate, and recent owner reviews. Primo ceramics are sometimes restocked weekly and sometimes back-ordered; the live listing is the only reliable source.
What's the warranty on the Primo Oval XL 400?
Primo backs the ceramic shell on its flagship kamados with a long-term warranty (often lifetime on ceramics, with shorter coverage on metal parts and gaskets). Warranty terms only apply when you buy through an authorized seller — verify the seller's status on the brand's website before ordering, especially from third-party Amazon listings.
What accessories should I buy with the Primo Oval XL 400?
Start with three: a wireless probe thermometer, a fitted cover for this specific model, and a chimney starter for fast, clean lighting. Add a Nomex replacement gasket around year two. Brand-specific accessories like deflectors and racks are usually included on premium ceramics — check the spec sheet on the Amazon listing before buying duplicates.
How does the Primo Oval XL 400 compare to a Big Green Egg?
Both are premium ceramic kamados that will last 15+ years. The practical differences come down to what ships in the box, accessory ecosystems, and dealer networks rather than cooking performance — food tastes the same. See our comparisons section for the side-by-side that matches your shortlist.
