Using a standard portable dehumidifier in a bathroom is generally advised against primarily due to severe electrical safety risks in a "wet zone" and limited effectiveness against high-volume steam. Most,, household units are not designed for high-humidity, wet environments and may pose shock risks, with better alternatives being dedicated extractor fans, opening windows, or using specialized non-electric moisture absorbers.

Is it okay to put a dehumidifier in the bathroom?

Yes, you can use a dehumidifier in the bathroom to control moisture, but it's often safer and recommended to place it just outside the bathroom with the door open to draw out humid air, especially with standard electrical units due to electrical safety regulations in wet areas. If you do use one in the bathroom, ensure it's specifically rated for humid environments (IPX rated), keep it far from splashes, or opt for a non-electric moisture absorber for maximum safety, as mixing standard electrics with water is risky.
