Agreed. and since windows make an essential and large part of a space, Curtains/ blinds become an important design element.

Just make sure whatever you install is able to be opened from the inside for getting out in case of fire. If you are the only house on the block with bars, it often draws savvy thieves as they wonder what you have in your place. If most of the block has bars, put them on too. Because then the lazy thieves will not go after the easy pickings, your place. I've been in big urban where both were true, either one or two houses on the block had the bars and they were targeted; or everyone pretty much did and whoever didn't got lots of breakins. One house I rented that had bars, they had some funny latches the landlord had to show me how to work, so I could get out of the house if I needed to for fire. It was code, the latches.

HI -- I have the very same bay windows . I put Hunter Douglas wood blinds fitted to the windows and have hanging drape side panels on the side walls on each side of the bay . So nothing hanging in the middle . I have the panels ( 95 inch length ) hung from the full wall height (8 ft.) on a rod that goes across the width of the whole wall. Or you could just have the rod the with of each side wall ,having a finial on the interior ends . So that would be ,two small rods with 2 wall cup brackets and two finial ends . I am not a fan of the shutters because of the cost but mostly because they block too much of the light and view . Have the window blinds and the bay interior the same color .

First you need to decide on the look you want to have on your bathroom. If it is classical stained glass suits the better and for modern go for frosted glass. But before going to stained glass make sure that the bathroom furnishing and fittings should be in a classical type. Where as for the frosted the bathroom furnishing and fittings are readily available in the market.
