window film and no curtain

Is heat ans UV an issue? If so do solar shades if not nothing

Lovely window.

What is your decor style? I know I’d want some type of curtain there for softness, prettiness, and to not have a stark black hole at night. It could be sheer to let light in. Lots of possibilities.

What will be under the window? How will the shower be built? Can you show a pic from further back?

I can see your neighbors, so they must be able to see you.

I like the window open too. How about a long planter under the window with mother-in-law tongues or some other plant that blocks the lower 18 inches of the window.

Based on what I can see of the neighbors, I would want something pretty there to block out at night.

Ditto the window film suggestion. https://www.amazon.com/s?k=Window+film&crid=2VBQJWVQ0KPXC&sprefix=window+film%2Caps%2C115&ref=nb_sb_noss_2

Thanks for the ideas; I’m definitely thinking I want something that let’s a lot of light in. Here are a couple more pictures for perspective with shower. Still very much in the middle of the work right now. The tub will be under the window, wood floating shelves on the wall adjacent to window.

I‘ll bet you’re excited! It’s looking nice.

I’m not a fan of unadorned windows at night, especially amid the hard and cold surfaces in a bathroom.

Are you sure your neighbors cannot see in? If they can't, then I would just go ahead and leave it open as is with nothing on it. It is an interesting window as is. When films and blinds go on it starts to look more like a McMansion special.

Here’s one more picture for perspective of what you can see standing outside my bathroom window.

If you feel like splurging .. glass frosted with a pattern adds a “special” look to a window that large…..sheers come in beautiful patterns as well… rather than a solid shade…depending on your final decor choices…a hanging plant …or three ….would probably thrive there

I agree…anything you do …should leave lots of clear space…interspersed in a pattern…they do make a “frost” spray in a can…but it does not hold well when cleaned or scrubbed

Plantation shutters?

I have them without the stick.

You'll probably want something that follows the arch:

Arched Window Treatment Ideas

Your bathroom layout looks to be the same as mine. We have an arched window over the tub and we put a plantation shutter. I leave it opened a little bit to let in natural light, but not enough for the neighbors to see in. That being said I like the picture of the relaxed roman shade that someone posted above. Looks like the top part is stationary and the bottom part can be moved up and down.
