The Bathtub

 circulation pump swirled water through the heated bathtub while a pipe released detergent. A thick rim prevented water from flowing out as the tub was being cleaned. Air jets dried the tub, and could be used to dry bathers, too, if desired. The sink came with a button that, when pushed, emitted a mix of detergent and water to clean the inside.
