Atrio Post Single Hole Faucet The new Atrio bath line from Grohe is the embodiment of classical modernism. Conceived along traditional Bauhaus lines, Atrio uses "reductive clarity" as its central design principle. Appealing to the trend toward simplifying the home environment, the key design elements of Atrio rely on the basic geometry of cylinders and right angles. Grohe's Atrio line finds its place where elegance is defined by purist sensibilities.
