hi cool qatar
when we find dual voltage in the bathrooms ,it is only for either 1- shaving machine or 2- hair drier machine.you can't use the iron from that outlet,because the iron needs more watts.if u want to use any appliances that is 120v ,u can buy a transformer from 240v to 120v and put it in any location in your house ,so u can use your 12v stuf .
