The Primo Ceramic Oval All-In-One Series is unique in the kamado world because of its patented oval shape, which allows for true two-zone simultaneous cooking (direct and indirect) that is much harder to achieve in traditional round grills.
The "All-In-One" package is designed to get you grilling immediately. It includes the fully assembled grill head, a sturdy cradle with locking casters, fold-down side tables, an ash tool, and a grate lifter.

Individual Features
1. Oval Junior 200 (The Compact Powerhouse)
The Junior proves that size isn't everything. It’s the largest "portable" ceramic grill on the market when used with the Primo GO base, but in the All-In-One configuration, it’s a compact backyard hero.
-
Capacity: 3 whole chickens, 4 steaks, or 1 small turkey.
-
Unique Feature: Excellent fuel efficiency; it can hold a low-and-slow temp for hours on a tiny amount of charcoal.
-
Weight: ~110 lbs (Grill only).
2. Large Round (The Traditionalist)
While Primo is famous for ovals, they offer this round model for those who love the classic kamado aesthetic but want American-made ceramic quality.
-
Capacity: 4 whole chickens, 6 steaks, or 8 burgers.
-
Design: Unlike the ovals, it uses a 18.5" diameter circular grate. It's the only one in the lineup that doesn't offer the native "two-zone" oval advantage, though you can still use deflector plates for indirect heat.
-
Weight: ~150 lbs (Grill only).
3. Oval Large 300 (The Family Favorite)
The Large Oval is arguably the most practical size for the average household. It’s wide enough to fit full racks of ribs without having to cut them in half.
-
Capacity: 4 whole chickens, 2 whole turkeys, 6 steaks, or 12-15 burgers.
-
The Advantage: It offers significantly more lateral room than the Round model, making it much easier to bank coals to one side for a sear/rest setup.
-
Weight: ~152 lbs (Grill only).
4. Oval X-Large 400 (The Best Seller)
This is Primo's most popular model. It provides a massive 400 sq. in. of primary space—enough to smoke two large briskets or 20 burgers at once.
-
Capacity: 8 whole chickens, 2 large turkeys, or 12-15 steaks.
-
Professional Specs: The All-In-One XL is a "forever grill" for many enthusiasts because it handles everything from a pizza party to a 16-hour pulled pork smoke with ease.
-
Weight: ~250 lbs (All-In-One package).
5. Oval XX-Large (The Colossus)
The XXL is the largest ceramic grill ever made. It is designed for those who never want to run out of space, capable of feeding a crowd of 20+ people.
-
Capacity: Over 20 burgers or a small army’s worth of ribs.
-
Design: Because of its massive weight and size, the XXL All-In-One cradle is exceptionally heavy-duty. It requires a significant amount of charcoal to fill the firebox, but it retains heat like an industrial kiln.
-
Weight: ~282 lbs (Grill only); shipping weight is over 300 lbs.
