Do you want bubbles? If not, I recommend Aromatherapy Associates products. Their oils are gorgeous, and the shower oil is great in the bath too. You rub it on your skin and get in the bath, and the water goes milky - you feel like Cleopatra and smell amazing.
A cheaper alternative is the Aldi dupe of Laura Mercer Honey bath foam. It comes in a jar with a wooden honey dipper, and has a lovely smell. It foams (not lots of bubbles, but a decent foam) and your bathroom will smell good the next day, too.
