In the olden days, pine and lemon were just about the only options when it came to bathroom fragrances. Fortunately, there are a lot more options available nowadays. Lavender, vanilla, and coconut are all enticing options. Fresh "ocean breeze" or "clean laundry" scents can also work. Try to steer clear of any strong floral fragrances, especially if the bathroom is small. If the scent is too intense, it can cause headaches and/or nausea.
