A bathroom tends to starts smelling weird and damp if the moisture is not taken off and cleared out often. A damp bathroom can not only smell bad but it can also lead to the growth of several microbes, molds, and mildew. Then that would lead to allergies, skin rashes and breathing problems. So it’s always better to try and keep a bathroom as clean and dry a possible. Keep a dry mop always at hand.
After a bath, mop the floor and wipe the residual water from sinks, furniture and walls. Make sure that the shower area is dry, especially the walls around it. You should definitely invest in an exhaust fan so that you can make sure that whatever parts you have missed out can dry up faster, keeping the bathroom dry. Spray some room freshener or use potpourri to make it smell nice too.
