What's a bathroom?
A bathroom is a room containing a sink, toilet and also a bathtub or shower. It;s also usually considered a service room.
Use less water while in your bathroom for example instead of keeping the water on the whole entire time you brush your teeth turn it off until you're done brushing them to wash your mouth and the sink out. Try to use less disposable products in your bathroom like paper towels instead use hand towels like you would a face towel. Lastly when cleaning your bathroom use non toxic sprays to help the air in your bathroom.
