Construction of a pipe for supplying the urinal.
—
Hidden. As the name suggests, in such models the nozzle is hidden inside the body and with normal installation outside is not visible. This makes it possible to ensure a neat appearance, without unnecessary hoses and piping. On the other hand, the hidden installation is generally more difficult outside.
—
External. The external pipe makes it much easier to connect a hose or water pipeline, but the urinals themselves do not look as aesthetically as the models with a hidden supply.
—
Anhydrous. Specific type of urinal, which does not require water supply at all. The drain hole in them is equipped with a specific device (usually an air shutter or a special cartridge) to prevent the spread of unpleasant odors, and the bowl, as a rule, has a special coating that ensures hygiene without constant washing with water. Such models are extremely economical to use, but are themselves quite expensive.
