Elegant Accessibility. At first glance you can't tell that the Elevance Rising Wall Bath is a walk-in tub. Instead of passing through a clunky swinging door, bathers step over a lowered wall, which they then pull up to allow a soaking depth of 14 inches above the tub's built-in seat. Water enters the tub through a slot that produces a waterfall effect. According to Kohler, a full tub takes less than two minutes to drain. The fixture costs $8,775; a jetted massage option costs another $1,000. Kohler Co., 800/456-4537, kohler.com
