Aromatherapy candles, soaps, moisturizers, cleansers, oils and perfumes are always popular bath gifts. If those on your list can't afford a spa treatment then let them pamper themselves at home with the great body and bath product links above.
Manicure kits, shiatsu massagers, fragrance burner sets, and manicure and pedicure kits, can make someone's "personal time" that much more revitalizing. Gift baskets are a great way to mix in a variety of items that you know that person will enjoy. For men, skin moisturizers, electric shavers, and colognes are a few excellent gift ideas.
