I wouldn't drywall over the window. Take a look at the options for recycled brick, they may match better than you think.

Kind of funny really how many people would feel exposed and would not want to use the bathroom. The more I think about it, it's a bit like a public restroom with stalls (as stall walls rarely go to the ceiling or floor and have the added issues of gaps between the wall panels and doors -- which thankfully we won't have!). Regarding the humidity control issue, I should have clarified this is only for a toilet and small hand basin (not a full bathroom with shower). The main room on the other side of the proposed toilet is our dog whelping room where we will have young litters of puppies (when we have them). Further down the hall, removed from this room, is our training room where there are likely to be other visitors but the proposed bathroom would be quite removed from that area. It would be wonderful to find more windows like the ones that are up near the ceiling! That would certainly solve the issue. I'll have to scour the demolition/restoration places.

You could use a solar shade. They're easy to wipe down, and if you choose the right openness, you'll have your privacy, too. http://www.selectblinds.com/solarshades/extreme-roller-shades.html http://www.selectblinds.com/solarshades/designer-roller-shades.html Good luck!

I have a 1970s townhouse that we are wanting to modernise - especially our front entrance. We are trying to decide what to replace our front window which is yellow old fashioned glass with. We have a private front garden so no one can see in from the road however not sure if we should still have some privacy glass given it’s beside our front door. Our options are an obscure glass such as cathedral design or to put clear glass in and do an interior window covering such as a blind if we find we do want some privacy at a later date. Just not sure what would look best from the outside. Any suggestions would be welcomed!
