Customer Questions & Answers

What is the length of the cold lead for a mirror defogger?

A mirror defogger cold lead is 36 inches long.

How does a mirror defogger work?

An electric heating mat is attached to the back of the mirror, which transmits gentle warmth across a mirror’s surface to prevent moisture from condensing on the mirror's surface during a shower or bath.

How quickly can a mirror defogger defog a mirror?

The mirror defogger will begin to defog the mirror within 5 minutes of operation.

How do I glue a mirror to the wall and still have a defogger on it?

If you're gluing a mirror to a wall, simply apply adhesive to the mirror backing, not covered with the mirror defogger.

Can I wire it to the lighting circuit?

Yes. In fact, this is the most common way to operate a mirror defogger.

Can I use multiple defoggers on the same mirror?

Yes, but please make sure not to overlap multiple heating elements over each other.

Can I trim the mirror defogger?

No. Mirror defoggers can't be trimmed and the proper size needs to be selected to fit on an open, unobstructed area on the back of the mirror.

Can I put a mirror defogger in my shower?

No. Mirror defoggers are not rated to be installed in wet locations like a shower enclosure.

Can you attach it to the back of a medicine cabinet door?

No. Mirror defoggers are designed to be mounted and wired to a fixed, wall-mounted mirror.

Great product. The defogger works great.

James W., Richmond, VA on 01/31/2019

The defogger works great. I added plugs and plugged them into recessed outlets that were installed in the remodel. They are in the same circuit as the exhaust fan, so the mirrors start heating when the fan turned on as soon as I enter the shower. I was nervous applying them to the back of the mirrors as the instructions said not to do any trimming, but realized that the excess could be trimmed off safely. The instructions should have pointed out that the oval ones might need to have the excess unnecessary adhesive material (without the wires) trimmed to conform to the mirror's shape unlike the adhesive backing which was not rectangular.

Easy and Straight Forward Installation

Jay j., BALDWIN HILLS, CA on 06/08/2016

The element itself is almost too beautiful to put on the back of the mirror! And works great! The service from your team was awesome and speedy! Really first rate!

Works great.

Sanford P., GAINESVILLE, FL on 05/16/2016

Works great. Was easy to install. I wired it so it turns on with the shower fan and the shower light.

Excellent product!

Great product!

Margaret C., Lexington, SC on 08/31/2012

Great product! Does work better for new construction because of the need for power. But I put it in an existing bathroom during a refurb.
