Comparison Grohe Bau 39439000 vs Grohe Bau 39438000

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.
