Abstract: A shower water-saving device with dual functionalities: collecting water from a showerhead and watering household or landscape plants. The device can be used to conveniently catch the leading cold or lukewarm water from the shower head, which would otherwise be wasted, while the person taking the shower is waiting for the water with proper temperature to come and, after collecting the shower water, it can then be easily transformed, by attaching a lid (preferably having a spout) to the top opening of the bucket, into a hand-held watering bucket and be used to water household plants or plants in the garden or on the lawns.
