I have a cup next to the bathroom sink. I catch water first. Shut the water off. Moisten the brush. After brushing I rinse with the water in the cup and rinse my brush in the cup. I also have a small bowl in the sink that catches any running water. I add that water into the bucket that catches cold water in the shower.
