Choosing the Right Electrical Wire for Your Bathroom: A Quick Guide

For a bathroom, you’ll need to use a 12-gauge electrical wire and install ground fault circuit interrupter (gfci) outlets to prevent electrical shock and ensure safety. Bathrooms require electrical wiring that can withstand moisture, and the 12-gauge wire is the standard measure to accommodate the ample electricity requirements for a variety of appliances, such as hair dryers and curling irons.

In terms of safety, gfcis are mandatory in bathrooms and other wet areas, as they cut off the electricity flow immediately if an appliance comes into contact with water. By following these guidelines, you can ensure that your bathroom wiring is safe, reliable, and up to code.
