The bathroom outlit is only for very low wattage items like a shaver or phone charger. You can buy a transformer, but for high wattage items like a flat iron, you would need a fairly large one. It may be easier just to buy a new iron here. BTW, you may find that many of your electonic items (especially those with a power brick) are dual voltage. Just check the back of the unit or go on line to check the specs.
