How Do Fogless Mirrors Work?

Facial hair is in, and until David Beckham shaves off his glorious tuff this trend isn’t going away any time soon. But, even the biggest facial hair aficionado knows that maintenance and keeping it clean is key to making it looking attractive and (mostly) professional.

As Zadro Beauty Products’ resident beard enthusiast I have subjected my face to many hours of manscaping, and have found that shaving in the shower gives you a much better result than when you shave over the sink. The warm water opens up your pores, softens the hair, keeps your sensitive skin from getting razor burn and can even save you time and money.

Men today rarely shave in the shower because there’s no mirror in there to see what you’re doing. Even if there was one, it would quickly fog up, rendering it useless. So, how do you get the best shave and keep your mirror clear so you can see what you’re doing? Glad you asked.

I present to you a fresh take on an old technology: fogless mirrors.

There are many ways to make a mirror fogless. There are super-expensive installations and low-budget DIY toothpaste/soap hacks, and then there are fog-free mirrors that are budget-friendly, take less than five minutes to install and are a worthwhile investment for anyone who shaves regularly.

Now, I don’t have the room (or the funds) to have a super-expensive installation, nor are my mirrors fighting tooth decay. So, I’m going to tell you about the three main types of fogless mirrors out there and give you some pros and cons so you can decide which one would be the best fit for you.


Fixed water-heated mirrors work by directing a constant stream of hot water from the shower head directed to the back of mirror. The hot water from the shower matches the surrounding temperature and, through the miracle of science, prevents condensation from accumulating on the glass – keeping your mirror crystal clear. This style is preferred by those who want a more permanent solution.

Pros: There’s no need for fogless sprays, it offers one-time installation with no suction cups or adhesive and you can easily adjust the mirror height.

Cons: It’s fixed to the shower head, which may not be a pro. It’s also non-portable, and if not maintained properly soap scum can accumulate in the movable joints.


Portable water-heated mirrors work much like the fixed variety, but instead of a permanent water connection they use a hidden reservoir for temperature control. Just lift the mirror off its base, fill it with water from a shower head and slide it back on. Most of these mirrors come with suction cups for mounting, but also include an adhesive for more permanent installation.

Pros: It’s durable, portable and adjustable, and most come with an LED light for improved grooming.

Cons: It’s not fixed, and must be filled with water for each use (though it’s easy to do).


This is the most popular choice based on the amount of pretreated mirrors on the market. Pretreated mirrors are coated with an all-natural chemical mixture that covers the surface of the mirror to keep it fog-free. You must be gentle when using a pretreated mirror. After multiple uses natural oils, shampoos and things in the air dissolve the coating and a new film needs to be reapplied.

Pros: They come in all shapes and sizes, they’re fog-free in and out of bathroom, and the fog-free spray can be used on other surfaces like windshields, glasses, windows, dive masks and more).

Cons: Continual maintenance and reapplication of film every few uses renders a large consumer base that reviews these mirrors as a short-term solution.

Hopefully, this guide helps you better understand the different types of fogless mirrors and how they work. If you have additional questions, the helpful staff at ATGStores.com can help you pick out a fogless mirror that’s just right for you.
