If you want the see-out-but-not-see-in effect, for daytime use look at mirrored window films. If you go that route and that will be the only treatment used, mirrored films give privacy to the side of the film that is darker. Typically in the day time people won't be able to see in, but at night when your bathroom is lit up and it's dark outside, the effect is reversed...you won't be able to see out but people outside can see in. So while that type of film is good for daytime, you'll need to couple it with a curtain or blind for night time. Or you can go the route of a frosted film. You'll retain some light transmission, but lose the view. There are numerous styles of frosted films, and the amount of light they allow to transmiss does vary. There are stained glass films too if you want to go decorative. That aside, for window shades, I like top-down-bottom-up for any actual window shade. If you're not familiar, with those shades you can lower it from the top (usually most effective in a bathroom), or raise it from the bottom, or both. If you can lose a little of the view and natural light during the day, then go with just a T-D-B-U shade. If you want to preserve the entire view, your best bet will be to use a reflective film. That'll give you privacy in the day. Couple it with a shade for night time use. If the view isn't important and you prefer to not have a window shade, than a frosted or semi-opaque film could be used. Color recomendations, I'll leave that up to the stylists.

Plantation shutters would look great but they are also very expensive for that size window and we don't plan on staying here too much longer. My husband and I plan on selling the house within a couple of years so I have been looking for ways to do some updates. My style is more traditional with oil rubbed bronze fixtures and deep rich colors like browns, cremes and a touch of burgundy. I the colors I have a pretty solid decision on, just looking for ideas on the styles. Since the window is on the main floor and it on the front of the house, privacy is a must.

Non functional and below are instructions on how to make, if you are handy https://www.artsychicksrule.com/no-sew-faux-roman-shade/ Ikea sells roman blinds for $40 that adjust to a few heights (by a magnet). They come in two sizes only, but maybe you’ll be lucky. You can place on rod or screw to window frame or wall. https://www.ikea.com/ca/en/p/ringblomma-roman-blind-white-30438518/?epik=dj0yJnU9R2NMb1FFYnkxdDZDc2xuQzFRLUlNdk4zektvNFVsLXMmcD0wJm49Vk5qZEdCWnZpa3RaaVlwQXhKWnpVQSZ0PUFBQUFBRl81NGdV

I love my plantation shutters, but you are right, it would not be an option. Years ago though, I recall bi-fold shutters, but in your case I don’t think it would work because it’s too close to the vanity, and it wouldn’t look good either. We did something unusual for my youngest who lives in an apartment in the city. Her window looks right across a courtyard to a music school. We put a blackout shade behind a venstain blind. She has so many options with this scenario. What if you put a plain window shade behind the Roman? The Roman can stay up most of the time, and you can just pull the window shade down at night. For me, easier then the contraption of the Roman. It is true that you never know who is looking and out on their deck at any hour. Certainly not saying they are doing it purposely, but, you want to assure your own privacy. Personally, I never turn the bathroom light on in the middle of the night. We have a nightlight that throws off just enough light. Could this be an option? When a home next door to a friend was being rebuilt to something bigger, she went to view the home to how see what views the new people would have looking into her rooms. I would never have thought to do that.
