Why don't you look through pinterest for a few hours and save the images that you like. I am sure that it's not impossible to imagine a modern midcentury, also contemporary, also boho and also minimalist style, also organic, all in one room, but if you keep looking on pinterest, maybe you will find it. Your general ideas are so broad, it's hard to help at this stage. You might also provide a budget, in order to help those that can help you here.

Also, it will definitely help to post a layout of the space, along with pictures, and let folks know what you are willing/interested to change about your layout.

Finally, I'm letting you know this is the remodeling forum, which will certainly help with many technical questions. But for design/finishes help, you're probably better off in the Bathrooms forum.

You need to post a layout. :)

BoHo and minimal do not go together and IMO BoHo does not sell houses. In small spaces best to keep everything simple with as few material changes as possible.
