When we remodeled our home, we decided to install a dual toilet-tissue holder. Most home toilets have a single holder for a single roll. A single roll, however commonplace, is, well, shall I say, awkward. When the roll empties, then what? As a result, whenever we saw the roll approaching exhaustion, we would place a new roll either on the floor beside the toilet or on top of the toilet tank. In either case, we were defeating the nice orderly arrangement of the facility. Wouldn't it be far better to have a place to put the roll?
