The term WASHING FACILITY can be broken down into two crossword solutions: BIDET (5 letters) and SINK (4 letters). A bidet is a plumbing fixture used for washing the genitalia, inner buttocks, and anus. It is typically installed in bathrooms and is similar to a toilet, but with a spray nozzle for cleaning. A SINK, on the other hand, is a bowl-shaped plumbing fixture used for washing hands, dishes, and other items. It is usually installed in kitchens and bathrooms and is connected to a water supply and drain system. Together, a bidet and SINK make up a washing facility.
