Sorry - that meant to be "HELP" instead of "HEP"!

You could go patriotic, get some vintage artwork and such. I redid my small powder room cranberry with white accents. I love it!

What about a red/white toile for the shower curtain?

I think you could do with something on the wall between the tank and the cabinet - maybe a small sign type thing.

Here is a link that might be useful: toile shower curtain

A friend of mine added a safari/ elephant border in place of crown molding. Then picked up the blacks, browns,and mustards with towels, shower curtain, artwork and soap/ tissue items. She found bamboo/cane looking candles and placed them on the toilet tank along with a bit of silk greenery
Really looks stunning!

black and white toile would be stunning.
