With the ORB fixtures/shower frame, as well as the tan tile, imo, a dark color would look very rich. I can't recall reading any posts where you've used white, but have focused on more dramatic, deeper colors, so that's my logic for suggexting a darker color, unifying what you have in your home already. I have the Bamboo Romans in three of the bedrooms and family room and love them. I've had no problem with any of them in the 7 years they have been up and my son was able to hang them, which was very easy. I have unlined, but they can be custom ordered w/lining.

Thermal functionality (keep chill out in winter, afternoon sun out during summer) is important to me Rule out plantation shutters…no thermal. In your photo, all your window trims are at different heights. You need to hang the rod the same for all windows. For dining room side window and bay front window, choose thermal lined to the floor panels which you can close when needed. Windows over sink…Roman shade, thermal lined, hung at the same height as the others. Good example…all treatments hung at the same height.(Roman will have to be an outside mount). Same fabric…

They of course WILL make them. and what they will not tell you is it is GONNA be a pain in the rear end. Over time, simply the lift and strain on rings and cords, and the heat that builds up with every yank, will "burn out" the cords. Then.......no matter how well crafted? Plan for puff and fluff ritual with every yank back to raised position. You can spend the money and find out. I wouldn't let a client do it at that width. Do as you will. Come back with the regrets: ) The treatment is INAPPROPRIATE for your windows. But yes....... someone will be happy to take your money. The corner will be the least of the issues. Hide an inside mount privacy treatment under a "fixed and never moving " roman shade valance. Or do not do it at all. Ya heard it here.

I would put them just above the window trim not halfway up.
