Iron Chests Mod (1.21.11, 1.20.1) – Better Than Vanilla Chests

Running out of storage space is one of Minecraft's most persistent annoyances, and Iron Chests Mod solves it elegantly by introducing a tiered chest system with significantly more capacity than vanilla options. Each upgraded chest — from Copper all the way to Obsidian — can be placed directly next to each other without merging into double chests, freeing you from that awkward one-block gap vanilla forces on you. With over 1.7 million downloads on Modrinth and support spanning from 1.7.10 to 1.21.11, this is one of the most established and trusted storage mods in the Minecraft ecosystem.

Key Features

• Tiered chest progression — Upgrade your storage step by step: Copper (45 slots), Iron (54 slots), Silver (72 slots), and Gold (81 slots), each crafted by surrounding the previous tier with the appropriate ingots and glass.
• No-gap placement — Unlike vanilla chests, every Iron Chests variant stays as a single chest when placed adjacent to another, so you can line up rows of high-capacity storage without wasting space.
• Shulker Box upgrades — The same tiered system applies to Shulker Boxes, giving your portable storage a serious capacity boost with Copper, Iron, Silver, and Gold variants.
• Obsidian chest blast resistance — Need explosion-proof storage? The Obsidian chest variant offers increased blast resistance to keep your items safe near TNT or Creepers.
• DirtChest 9000 — A tongue-in-cheek single-slot chest that only holds dirt. Comes with its own User Manual when crafted and is permanently placed once set down. Craft it by surrounding a Chest with Dirt.
• Multi-loader support — Available for Forge, Fabric, Quilt, and NeoForge, so it fits into virtually any modded setup.

FAQ

Can I upgrade a vanilla chest directly to an Iron Chest?

Yes — you can craft an Iron Chest by surrounding a regular vanilla Chest with Iron Ingots and Glass. You can also upgrade through the Copper tier first if you prefer a step-by-step progression.

Do Iron Chests work with Shulker Boxes?

The Copper, Iron, Silver, and Gold upgrade recipes also apply to Shulker Boxes. However, starting from Minecraft 1.13.2, Iron Shulker Box variants have been moved to a separate companion mod called Iron Shulker Boxes.

Is Iron Chests Mod compatible with Fabric and NeoForge?

Yes, Iron Chests supports Forge, Fabric, Quilt, and NeoForge. Make sure you also install the required dependencies — Architectury API and Cloth Config API — for your specific loader.
