There are coatings /sprays for this
You can also just rub some shaving cream on it and wipe it off.
Or soap
Or rain-x anti-fog or similar coating to achieve the same.
Or a secret room behind the mirror at a warmer temperature
I think in this particular case it might be an integrated heating element like this: https://clearmirror.com/products/shower-clearmirror
They’re popular in shower rooms in Japan.

A gee, thanks.
There is probably a hole cut into the wall there.
If you want an innocent explanation, then it’s entirely possible that there used to be a medicine-cabinet-style mirror there. It looks like it’s about that size and would fit in that location. Those medicine cabinets are recessed into the wall and so they require a hole to be cut in the wall. When they installed the large mirror, they didn’t think it was worth it to repair the hole, since they were covering it up with a mirror.
If the hotel is fairly old, it might have had something like that in the past.
But since there is no way of knowing that for sure, if I was in that room, I’d assume there’s a camera behind there, too.
Some hotels just put a hydrophilic coating on their mirrors. https://fsicti.com/markets/architectural-building/bathroom-mirror-shower-door/
Even so, there is no reason to downvote my comment. It is possible for there to be a hole there. Voting like that just makes you an asshole. And, yes, comment votes are public information.
This will never not be the saddest shit on this website, please go touch grass.
Alternatively, you can go fuck off instead. People who downvote and then reply to the comment as if they want to have a discussion are a fucking cancer.
Don’t believe any of the other comments, this is clearly a one-way mirror with a camera inside. That conspiracy theory you’ve been thinking about a lot lately is true, and even worse they know you are on to them. Remember that creak in the floorboards you dismissed as the house settling? Footsteps. The way your coffee mug was turned slightly counterclockwise this morning? Intentional. They watch you when you sleep, and know how much time you spend looking at your phone.
Or it’s what the top comment said. Sleep tight!
I had this happen in a hotel, and being curious I removed the mirror, and yes there was a hole in the wall behind it, no there wasn’t a camera there. It was just were they had ran the wiring for the lights on the mirror.
It would make sense that it serves like an access hatch to a terminal block that feeds the whole room. It’s simple, costs nothing, is easy to get to (compared to having it sealed in the wall), protected from splashing and prying guests, and close to where you want most lights and outlets.

protected from […] prying guests,
These are such a good idea. It works by having a heater behind the mirror which prevents the condensation.
Ps. Excuse the multiple posts. fedia.io was having a moment. I’ve deleted them now
You can achieve a similar effect at home by using your hairdryer on the fogged-up mirror!
You can achieve the same thing without wasting any (electric) energy by rubbing a bit of shaving cream onto the mirror and buffing it out. Works for a while.
i’ll be honest the amount of energy it took to produce, ship, and then sell that shaving cream to you dwarfs the cost of the power for a hairdryer that’s only on a few seconds. if you’re wanting to be pendantic about it that is overall more harmful to the climate.
not in a rude way i’m just sick of these BP-personal-climate-calculator-core takes about environmentalism. just because you prostrate yourself doesn’t mean it’s actually doing anything to help. live your life. we’re all gonna die within a couple centuries if we don’t overthrow oligarchy, tho.
Uhh, because of the heat of the raspberry pi & camera behind there
Suppose you were in this situation and suspected something. I’d imagine the space behind it would be totally dark, so what would be a safe way to check if there’s a gap in between without breaking the glass?
there are no “one-way” mirrors. You just need to make your side darker than the other side (there’s a reason the observation side of a two-way mirror is never brightly lit, but the interrogation room is)
Tldr: put your face right up against it and use your hands to block out as much light as you can

15 upvotes? Really? Mirrors are painted on the back with opaque paint.
Are we cross posting this to a flat earth science forum?
but a one-way mirror (also known as a two-way mirror) is one that you can see through in one direction
I read a long time ago that putting something flat against the mirror will show you. I think if the mirror is legit you’ll see the reflection directly on the surface, if it’s two way the reflection will look like it’s inside the glass.
But I’ve never had the chance to actually test that, so take it with a grain of salt.
Edit: Turns out this is incorrect; thanks to everyone for educating me!
It would be the other way around, if at all.
“First-surface” mirrors where the reflective layer is on the front of the glass are quite fragile, so wouldn’t typically used for residential applications (you’d remove the reflective coating by cleaning it).
A regular mirror has the reflective surface on the back of the glass (which is then is further coated with a protective paint), leading to the effect you describe.
I don’t however know enough to say one way or the other whether a surveillance mirror would becessarily be a first-surface mirror.
This is ancient advice for two-way mirrors, IIRC nowadays even legit mirrors can reflect directly from the front instead of the back. In this age of spy cameras this is mostly irrelevant.
Another tip was shining a bright light to illuminate the supposedly dark room on the other side, which again, would be way more expensive than a smoke detector spy camera.
Yes, darkening your room and then pushing a bright light up against the one-way, taking care to not have it leak into your room, should make the other room brighter so you can see it.
Not that this is a one-way mirror anyway.
