We put frosted in the basement BR, not really losing a view, cuz it would just be the back of landscaping anyways. But, in the two upstairs BR, we replaced the old frosted glass with clear, and I love the increased light along with the view of the yard. We have a very private back yard, and windows being up higher, I don't think anyone could see much. I am not planning on installing any window coverings.

Here are the photos. This particular glass is called "Linen" by the seller. You can't see it well on the pics, but as oberon476 said, it has one smooth side (facing the bedroom) and one lightly pebbled side (facing the bathroom). The installer is still working today on the second room and we told him about our night/light-experience. He was very understanding but said that other customers used the glass for the same purpose and he never heard back that they were not satisfied. He will forward the information back to the salesperson we worked with. He also talked about a film he might be able to apply and I discussed that already with my husband last night. I am not too excited about a film on top of the glass regarding scratches, durability, looks and cleaning aspects. I think our final solution will be to install a curtain from the bathroom side over the top of the doors as an additional privacy screen. Our neighbors are safe though (lol) because they have no views into that area. The curtain is not what I intended to have but anybody staying in that room should have the option to get as much privacy as they want. At daylight there is no problem and I like how the bathroom is flooded with light coming from the room. That was the case in the showroom. However, I now believe too that no glass door is really private when it comes to different lighting situations. Thank you all for commenting and giving me your thoughts.

Wow, those privacy films available at Home Depot are gorgeous! When we bought the house there was awful, ratty, badly applied frosted film in there (and also in front windows in the living room - I think a vampire lived there). I looked to replace it in the bathroom but the selections were UGLY. One issue is that not being able to see the sky and trees makes the space feel even more cramped than it actually is. Another is that the toilet is right next to the window, so there's less of the fuzzy-distortion effect at night when people are essentially back lit an a few inches from the shade. The outside solutions are intriguing but I think the space is too narrow - anything tall enough and opaque enough to provide privacy is going to make the room dark. Now, if I could get the neighbors to give up the reclaimed driveway space and plant some things there like the previous owner had... I'm definitely going to get some privacy film for my son's bedroom, which is also the guest bedroom. It's next to the bath so same issues with privacy. The lower part of the double-hung is level with the bed and just covering the panes in that section will make it much more comfortable to raise the shade. As it is it feels very exposed even with the sheer curtain. I'm still thinking a top-down/ bottom-up shade would work best in the bathroom. Is it possible to put them in a humid location? And can they be cut to length, or do you have to go custom for such a short window?

I don't think there's anything dated about frosted, but if you're worried about it get the film. You can always remove it later and put in a different treatment. We did window film in our last house because I didn't want to bother with a treatment. Honestly I would barely bother opening and closing a treatment because I'm not in the bathroom for hours, and usually the times I'm unclothed are happening in the early morning/later evening when, for at least half of the year, it's dark outside, so I would want the blinds to be closed. I'm not going to OPEN them while I'm walking out of the bathroom. And if you leave them open and someone undresses in the bedroom, only to walk into the bathroom and find themselves face-to-face with their neighbors...no. So really, whatever you put in there will likely be closed 99% of the time. I thought the window film was the perfect compromise between light, privacy, and how we'd actually deal with window treatments. We had a window treatment in our powder room that virtually never got opened either. I will have this dilemma in our house as well and will probably go with a window film again if I can find one big enough.
