Bathroom is the most controversial as well as intimate space at home. It produce much moisture and steam. So, can you put wall art in bathroom?
The answer is yes. Every room in house can be decorated with canvas art. Because the humidity is intermittent and canvas is very durable, it would not cause a problem. People in New Orleans have canvas painting on their walls and the humidity is average humidity of 74.5 percent on a regular basis!
But don't hang any valuable artwork. And keey doors and windows open whenever is possible to let artwork breath.
If you do want to hang expensive artwork in your bathroom, make sure varnish is applied to protect the art from humidity.
