The Global from Imperial Industries includes a Dirt Buster base with an open-grid floor design that allows more fresh air to circulate throughout the restroom. It has a convenient corner shelf, an extra roll of toilet paper and a large door latch that can be operated with the elbow rather than by hand to help prevent spreading germs. Units have a sturdy framework with a one-piece continuous doorframe. Upgrades include increasing the side panel thickness by 12 percent, and a tank and urinal that are larger, stronger and easier to clean. 800/558-2945; www.imperialind.com.
