You are not effectively waterproofing windows that are already installed.

millworkman: Mmmm, not sure what you mean, but our question was about window coverings that can withstand some "showering" not full immersion. The Corian to encase is in part aesthetics, part cleaning ease.

Ok so pretend I can sell you a pvc plantation shutter with stainless steel fasteners. How are you waterproofing the WINDOW. The existing window was never designed to get wet from the interior, how are you addressing that?

Millworkman is correct. You can't just use any old window in a shower unless you are planning on remediating all of the water damage you will get in a few years. Maybe your windows are fine to use in a shower but I would bet they're not. Even if they are, you also need to waterproof all around the windows.

If you didn't want to do that, put in a full shower curtain and hope for the best.

Folks, thanks for your comments & concern about the waterproofing around the window. We'll make a note to address with contractor (who has a 3-decade-plus record of outstanding work in the community, large & small projects). So please set that aside for now (as we are confident he will cover this, but will confirm) and talk to us about the window coverings themselves (which Hallett & Co has done, thank you!).

Like I said, shower curtain.

" (who has a 3-decade-plus record of outstanding work in the community, large & small projects) "

Doing it one 30 years does not automatically mean he is doing it correctly. Again you cannot waterproof an installed window. It will get wet. You will end up with water damage, rot and mildew.

anj_p, we are hoping there is nicer aesthetic out there.

millworkman, noted.

We have a similar situation. I bought a tension rod and curtain for the window. I chose a fabric without cotton in it, thinking it would be less likely to get mildew. We've had it hanging for 2 years without issue. It doesn't get hit directly with water, and we run a fan after each shower.

dani_m08: I do appreciate the waterproofing comments, but "noted, we will handle with contractor" and now to move onto what I CAN do (besides talk with contractor and we are months out yet), and that's look for blinds. Your suggestions have several interesting approaches and I appreciate that.

Shower curtains can be aesthetic and solve the waterproofing issue without having to replace your windows (as long as you use them every time you shower). And not sure what aesthetic you're going for but shower curtains can look just like regular curtains. Are you opposed to curtains in general?

Having had a window over a tub for the past 10 years, I can attest to the fact that the window treatments in our bathroom were rarely opened. Not sure how often you have yours open currently. No one wants to climb in a tub/in a shower to open/close window treatments for the relatively short amount of time we spend in the bathroom. Because of that, we installed window film on our window above the bath tub. Lets in light all the time which is great, but won't let you see a view.

Here are some roller shade shower curtains. There are a number options. Some are automatic so you would at least be able to raise them from outside the shower.

ang_p: Yes, we open & close our window coverings, climbing into the tub (or leaning), every day. In summer, x2 for opening & closing windows, plus another round for the shower. Which is why I noted the "relatively easy to open/close." The view is incredible. We won't be using curtains. The renovation will be modern, clean, more minimalist in style. Louvers, blinds are in order. The "drop from the ceiling" approach has some merit!
