A bucket of water is an item that players can make by using a bucket on a water source such as a fountain or a sink.
Like other vessels filled with water, a bucket of water has everyday uses such as turning flour into various kinds of dough, refilling waterskins, or filling watering cans, among others.
A bucket of water is used in quests such as Plague City (to soften the soil outside Edmond's house) and Clock Tower (to cool the black cog).
It was also used in the Lumbridge Rebuildathon in order to make mortar and plaster.
Like all vessels, this can be filled with Humidify.
There is an infinite supply of Bucket of waters in the house basement in the quest Hazeel's Cult. It's not required to complete that quest to access the basement.
