This Minecraft tutorial explains how to use the /fill command to change water to air with screenshots and step-by-step instructions.

In Minecraft, you can use the /fill command to replace a specific type of block with another. In this case, we want to replace all water blocks with air blocks within a fill range. Let’s explore how to do this in Minecraft.

Requirements

To run game commands in Minecraft, you have to turn cheats on in your world.

Fill Command to Replace Water with Air

Command in Minecraft Java Edition (PC/Mac)

In Minecraft Java Edition (PC/Mac) 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19 and 1.20, the syntax to change water to air using the /fill command is:

/fill <x1> <y1> <z1> <x2> <y2> <z2> air replace water

In Minecraft Java Edition (PC/Mac) 1.11 and 1.12, the syntax is:

/fill <x1> <y1> <z1> <x2> <y2> <z2> air 0 replace water

Definitions

  • x1 y1 z1 is the starting coordinate for the fill region (ie: first corner block).
  • x2 y2 z2 is the ending coordinate for the fill region (ie: opposite corner block).

TIP: Read our tutorial called Understanding the Coordinate System to learn about the XYZ coordinates in Minecraft and how to find your current coordinates.

Examples

Example in Java Edition (PC/Mac) 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19 and 1.20

In Java Edition 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19 and 1.20, to replace all water with air in the fill region with a starting coordinate of ~10 ~0 ~40 and an ending coordinate of ~-40 ~-3 ~-40:

/fill ~10 ~0 ~40 ~-40 ~-3 ~-40 air replace water

Example in Java Edition (PC/Mac) 1.11 and 1.12

In Java Edition 1.11 and 1.12, to replace all water with air in the fill region with a starting coordinate of ~10 ~0 ~40 and an ending coordinate of ~-40 ~-3 ~-40:

/fill ~10 ~0 ~40 ~-40 ~-3 ~-40 air 0 replace water

How to Enter the Command

1. Open the Chat Window

The easiest way to run a command in Minecraft is within the chat window. The game control to open the chat window depends on the version of Minecraft:

  • For Java Edition (PC/Mac), press the T key to open the chat window.
  • For Pocket Edition (PE), tap on the chat button  at the top of the screen.
  • For Xbox One, press the D-Pad (right)  on the controller.
  • For PS4, press the D-Pad (right)  on the controller.
  • For Nintendo Switch, press the right arrow button  on the controller.
  • For Windows 10 Edition, press the T key to open the chat window.
  • For Education Edition, press the T key to open the chat window.

2. Type the Command

In this example, we are going to replace all water with air in the fill region with a starting coordinate of ~10 ~0 ~40 and an ending coordinate of ~-40 ~-3 ~-40 in Minecraft Java Edition (PC/Mac) with the following command:

/fill ~10 ~0 ~40 ~-40 ~-3 ~-40 air 0 replace water

Type the command in the chat window. As you are typing, you will see the command appear in the lower left corner of the game window. Press the Enter key to run the command.

Once the cheat has been entered, all water blocks in the fill range will be replaced with air blocks.

You will see the message “1640 blocks filled” appear in the lower left corner of the game window to indicate that the fill command has completed.

TIP: If the /fill command does not replace enough of the water with air, the remaining water will flow back and fill up the area again! So make sure you enter a large enough fill region with your coordinates.

Congratulations, you have learned how to use the /fill command to replace water with air in Minecraft.
