Hello,
Am on a roll with small fixing projects, just did the garbage disposal which was leaking through the sinkhole that had caused a nasty buildup below. Now all good.

Next: We got our bathroom renovated and changed the windows. I don't have blinds yet. I am looking for something to put on the window glass. One is a rectangle and the other is a semi circle.

1. One way view. We should be able to look outside but view from outside should be blocked.
2. Should allow good amount of light.
3. I don't want to stick anything to the glass. Looking for static cling or something like that.

Is there anything like this? Any recommendations?

Amazon has plenty that are put on with just water/static and peel right off when you want to remove. Example below. I have used these types of films on my garage windows and backdoor. They work great for the price. With it being a bathroom, you might want no see through just fyi. At night people would see right through it still as light would be coming from inside. Just choose the width you need and the design you like. Amazon keywords "window privacy film"

we tore out our garden tub and small shower and made a large walk in shower. There is a large window in our bathroom that we previously used wood blinds but we wanted more light. We used this and it works well for us. sorry not a great picture but this is the only one I had in my phone and it catches just a small corner of the window

You likely aren't going to be able to utilize 1-way film. During the day when it is light outside you will get the reflection that you need to make it 1-way, but at night when it is dark outside and you have the lights on inside the reflection will work the opposite way allowing people to see in and not being able to see out. I think your best bet is a frosted/privacy film.

Filming through bathroom glass is illegal. And gross.
