Waterlogging

Not to be confused with Snowlogging.

A waterlogged oak fence.

Waterlogging is the mechanic that allows non-cube blocks (that is, blocks that do not completely fill their block volume, such as doors, ladders, and plants) to be filled with a water source block. Both the non-cube block and the water source block occupy the same space. If the non-cube block is destroyed, the water source block remains.

In Bedrock Edition, generally all non-cube blocks can be waterlogged and none can be used to displace water source blocks, although they can still displace flowing water.

Mechanism

In Java Edition, certain blocks have a waterlogged block state that can be true or false. This is a temporary solution; a full separation of blocks and fluids is planned.

In Bedrock Edition, waterlogging is handled by the game's layers system. Through editing, any block can be waterlogged, as well as other things such as placing multiple slabs into a single block. In normal gameplay, a player cannot displace water source blocks using doors or other non-cube blocks to create breathing spaces underwater, like one can do in Java Edition. Only flowing water can be displaced in Bedrock Editon.

Trivia

• Glass bottles can be filled up with water from waterlogged blocks, even if water is not accessible from the targeted area‌^{[Java Edition only]}. In Bedrock Edition, this is not possible since waterlogged blocks in general can’t be used to fill empty bottles.
