Example implementations relate to a mixing chamber for laundry supplies. For example, an appliance may include a mixing chamber to receive at least one laundry supply and a processor coupled to the mixing chamber. The processor is to identify a user-specified setting associated with a laundry load, determine a characteristic of the laundry load, calculate an amount of the at least one laundry supply to apply to the laundry load based on the user-specified setting and the characteristic, and provide the amount of the at least one laundry supply to the mixing chamber, where the mixing chamber is to mix the amount of the at least one laundry supply.
