Waterless urinals are an option for home installation. You can take advantage of all of the benefits that big companies and large facilities can, like saving money on utility bills and conserving water. You can save 1 to 3 gallons of water for every flush, and they are relatively inexpensive to purchase and install. Assuming you have two men in the household, a urinal can save about 3,250 gallons (about 12,302 liters) of water per year [source: Wilson]. Of course, there is a major limitation to keep in mind if you want to install a waterless urinal for home use. Obviously, only the men in the house can use it, so the potential for conservation is limited. Even if you don't have any women in your household, you will need to keep your old toilet bowl for your other bathroom needs and female guests. So, if you decide to install a urinal, it should be a second toilet. With that in mind, make sure you have room for both fixtures in your bathroom.
