A dark green bathroom looks richest when the stone matches the paint. Verde marble on the vanity, dark green on the walls, and the room reads as one material.
Fall bathroom decor, contained. Everything on the bath tray. A brown candle, a sprig of dried eucalyptus, a small glass of something. Nothing on the floor.
The easy Halloween bathroom: black candles on the counter, a small antique mirror propped against the big one, the overhead light off. It's creepy enough.
