Abstract: A water tub including a fluid delivery system utilizes a removeable carrier to provide fluids to the fluid delivery system. In some instances, the carrier is disposable such that depletion of the fluids within the container results in the carrier being thrown away and replaced by an unused carrier.

In some instances, the carrier can be manually attached and removed from the fluid delivery system without the use of any tools. In some such instances it will include a latching mechanism temporarily coupling the carrier to the fluid delivery system. The carrier may include a plurality of fluid containers, each container containing a fluid used for different types of maintenance of the water tub. The delivery system may utilize a dosing engine.
