Lavas stair fix

Lava’s Stair Fix is a Java Edition data pack that changes how much material stairs cost in survival. The numbers are based on how much of a block each item actually fills, instead of vanilla’s rounded-off recipes.

What it does

Stairs (13 wood types)

• Replaces vanilla’s 6 planks → 4 stairs with 6 planks → 8 stairs, in the normal stair shape.
• Adds a second recipe: 3 planks → 4 stairs, in a small L-shape. It fits in a 2×2 grid, so it also works in your inventory crafting grid.
• Covers oak, spruce, birch, jungle, acacia, dark oak, mangrove, cherry, pale oak, crimson, warped, bamboo, and bamboo mosaic.

Why you might want it

A stair is 3/4 of a block, so 8 stairs are exactly 6 planks of wood. If vanilla’s stair costs feel wasteful to you, this brings them in line with the real volumes.

Before you download

• This makes stairs noticeably cheaper than vanilla. Stair crafting yields twice as many stairs per craft.
• It is built for pack format 101 (Minecraft Java Edition 26.1.x). It will not work correctly on older versions.
• It replaces vanilla’s recipe files for the 13 stairs listed above. If another data pack changes the same recipes, the pack that loads last wins.
• The new 3-plank stair recipes work in the crafting grid, but they do not appear in the recipe book on their own. To unlock them, run /recipe give @s * (or /recipe give @s lavas_recipes:oak_stairs_small for a single one).
• This is a data pack only. It works on servers with no client mods needed.

How to install

1. Download the zip file.
2. Put it in your world’s datapacks folder (saves/<world name>/datapacks), or add it when creating a world.
3. Run /reload in the world, or rejoin it.
