Hang some DIY crates on the area over the toilet to add some decor. The dried beach dahlias in tiny bubble vases, mason jars filled with candles & bath salts, some driftwood, and a few starfish & shells make your bathroom super fantastic.
By the way, I HATE the newest, cutsie, pretentious word - "up cycle" - you're being creative and reusing what would otherwise be called JUNK/TRASH! Repurpose / recycle - just call it that! Up-cycle is putting lipstick on a pig!
