Some of us struggle with the issue of where to store supplies in the shower. Not happy with the idea of suction-cup soap holders or over-the-shower-head shampoo racks? Consider the versatile Mercer Bath System, $149 from Pottery Barn. Install the 36-inch-long bar in your shower or bath and you get instant storage: three hooks and two hanging caddies (one round and one rectangular), perfect for stashing shampoo, soap, sponges. Bonus: the polished nickel finish is lacquered to stand up to moisture.
