A simple shade on the window since there's a lot going on in there already. Looks great btw. I like the rug, nice modern touch in a very traditional room. Great job.

What a fun bathroom. Not a design professional, but I did just build a home! If you want neutrals, I would go sheer light shade and a smaller, lighter rug.

You won't have room for drapery hardware, but a nice sheer would be lovely. Depending on privacy needs, you could either do an RTB (rod-top-and-bottom), cafe style with the rod at the midpoint or all the way up; all inside mount. I'd suggest three times fullness.

I wouldn't normally recommend this, but inside mount panels may just work in your room......

A diamond earring would be lost in that rug.
