Buying Guide
What size should I choose? A 36 inch liner typically fits pits with a 36 inch outer diameter and a ~30 inch inner diameter. Confirm the inner diameter if you plan to use a grill grate or insert accessories.
Which features matter most? Consider airflow design (top/bottom vents), material (steel, corten, zinc-coated), and whether the liner is intended for above-ground or in-ground installation. Smokeless claims depend on airflow and wood quality.
Durability versus weight? Heavier steel rings tend to be more durable and resistant to deformation, but may be harder to move. Look for reinforced rims or double-layer constructs if you need stability over time.
DIY friendliness? Some kits are four-piece or modular, making installation easier for DIYers. Check whether additional accessories (grates, lids, or rings) are required or sold separately.
Maintenance considerations? Open-bottom designs require periodic cleaning of ash and careful placement to avoid debris falling through. Rust-resistant finishes help with longevity in wet climates.
