Yep. It’s a relatively new town house – maybe 5-7 years old? There’s a big window over the tub in the master bath. Not frosted, either. It is on the third floor, but looks across a courtyard at another row of town houses.
My 100+ year old house has a tall window in the bathroom. Both the toilet and bath tub are right there next to the window. No frosted glass.
Until we remodeled the bathroom and replaced it with glass block, our house (built in 1923) had a wood-framed window in the middle of the shower/tub. And no, the glass was not frosted–until we replaced it, we had put up that frosted film on it so our neighbors couldn’t see us in the bathroom. We didn’t actually use that shower for the first two years we lived in the house, though–the wood around the frame was already starting to rot, as well as the drywall behind the shower insert. Yuck.
My home has a window in the shower, and I’ve lived in several others with the same feature. Doesn’t seem all that unusual to me.
While looking for houses a few years back, I saw one that had almost the entire bathroom outside wall consisting of those thick glass blocks. Decently private and very interesting.
My house has a frosted window in the shower, with a plastic sheet in front of it so water doesn’t pool in the sill. I don’t have any complaints, except that the window opens from the bottom-up, instead of the top-down, which makes me even less likely to open it, but whatever.
My friend’s apartment had a non-frosted window in the shower, with no plastic sheet and a venetian blind 
for privacy. It looked about what you’d expect a blind in a shower for a year to look like.
The apartment I lived in about two years ago had a window in the shower, but it was frosted. The building is only three years old or so.
Oh, yeah. Back in Michigan I had a 2nd floor place that had a window next to the toilet. I can’t remember if the glass was frosted or not, but the window was usually open and if you were in the backyard, you definitely could have seen my winky while I was peeing.
ETA: Not like I was trying to show off my winky.
/Just stay outta my yard!
Yes I have a window in my bath tub at my apartment. It’s an old fashioned stand-alone so I can using a shower curtain that goes all the way around to block the window.
My dad’s house has one. It’s clear glass, too.
I do- eek, don’t peek! My bathroom wall is shared with my sunporch wall and there is a window there with a handy ledge for my shampoo and stuff.
The last house we rented did and this really old apartment house that I lived in in Cincy had small window in it.
My mother’s house does. I have lived other places that did. My current house does not.
I have two windows in my bathroom. One is over the toilet, it’s about five or feet form the floor. The toilet however is separated from the rest of the bathroom by its own door. There is also a second normal window at normal window height above the tub but the shower has a separate stall. My house was built in 1999.
The house I grew up in, built in the late 50’s, had a frosted glass window over the tub. The house I live in now, which was built in the early 90’s, has a bleeping greenhouse window over both the shower and the bathtub. It’s WAY up high, adjacent to the roof on the second story, but one time I was taking a shower and realized some guys were trimming the palm tree just above the window, about 30 feet off the ground.
Yes, they could and did see in. Pretty funny, actually.
I’ve lived in four places with shower windows (including one stained glass window in a pre-war walk-up in St. Louis), as an adult.
Our house, built in 1941, does, on the first floor. You can stand in the shower and look at the neighbors if you like – at least three different houses in full view. If the neighbors looked back, they could see me from about the bellybutton up. No frosted glass, and it’s framed in wood (:smack:) so it has a shower curtain for a curtain. We tend to keep that closed…
Most of the apartments I’ve lived in here in RI/MA have had a window in the shower. The apartment I’ve been in for years has one, but it’s been walled over. Inexpertly, and with not nearly enough insulation. As in, they just put up some sheetrock or whatever, over the window, with the curtain still in it, and put in the shower.
My current house has a window in the shower that goes from about a foot off the ground all the way to the ceiling. We have a shower curtain hanging over it that’s low enough for me to see over, because the view of the mountains is great. I’d leave the curtain off, but if we have the curtains in the living room open, you can see right into the shower from the living room.
My last house had a jacuzzi tub in a corner of the bathroom. Both adjoining walls had windows going from a few inches above the rim of the tub to the ceiling. There were blinds, but we liked to leave them open–the nearest house was over 1/4 mile away and blocked by trees. Most of the view was our own pastureland.
I’ve lived in a couple places that had them and I like them. It’s definitely something I’d want if I ever design my own house.
My (1950’s suburban ranch) has a window over the tub. The windows have been replaced over the years, so I have no idea whether the original was clear or frosted. The window sill (I just measured it) is 47" above the floor of the tub. In addition to the frosted glass, we have a curtain over the window so we can open it and still have our privacy.
