Much like an automobile, the human body requires proper care to stay healthy and good-looking for calendar photos. Maintain your natural mode of transportation with today's Groupon: for $15, you get $30 worth of natural, handmade bath products at Naked Body + Bath.

Naked Body + Bath lets customers' imaginations run wild as they dress up raw, unscented bath products with a profusion of oils, botanicals, milks, and glitters. Guaranteed to be at least 95% natural and free of parabens, chemicals, and spiders, every product is available for in-store sampling, giving customers the chance to try before they buy. More than 200 fragrant oils and 50 essential oils can be released into soaps, creams, salts, and lotions to enhance basic wholesomeness, and a host of already-concocted recipes are on hand to help to spark ideas. A bar of Casablanca soap ($7.95 for a 4-oz. bar) emits soothing pheromones of cedar, sea moss, and spice, and the Kelp Help spa bar’s seaweed and Dead Sea mud whisper of exotic locales where skin can take root and grow like a plant ($8.95). Banal basins take on a party vibe with a Breakfast at Tiffany’s bath bomb, which turns water pink as it fills tubs with vibrant notes of grapefruit. Should you happen on a masterpiece of your own engineering, the staff will write down your recipe and keep it on file to recreate at your bidding. Weary feet are welcome to sample any of the hoof-healing ointments and scrubs in a complimentary foot-soak treatment, but only after making sure their dogs can swim.
