Des Plaines, IL: Geberit’s Concealed Tank and Carrier system helped Siol Studios create balance in the master bathroom of the home selected for the 2013 San Francisco Decorator Showcase. The bathroom was a relic from the 1950s that was out of date in both form and function.


“This space needed some serious changes  –  a total overhaul,” says Jessica Weigley, principal of Siol Studios in San Francisco. “The original design had one sink in the corner, a bidet was located in front of one of the windows, the toilet was in an area set off by itself, and the shower was one of those shower/tub combos enclosed in glass.”

The new concept creates an unfolding space: Two people can easily inhabit the space at one time, moving fluidly between shared and private zones. Three different zones were created within the space: the entry zone, the tub zone and the transition zone with different areas of passage.

“In order to conceivably have someone washing their hands in one area and another having privacy in the commode area,” says Weigley, “a wall-hung toilet was the clear solution in this case.”

“The wall-hung toilet was critical for this layout to work; it is a great way of conserving space and having a beautiful aesthetic,” she continues. “Without that, we wouldn’t have had enough space to be able to walk through. We would have had to have a completely different layout.”

The Geberit System provides design freedom by taking the toilet off the floor and mounting it on the wall, while concealing the tank and other functional components. It helps unlock imagination like never before. Safely hidden behind the wall, Geberit’s in-wall technology allows a more streamlined and clean look from floor to ceiling. “Ultimately, we just really like the way that it looks,” says Weigley.

Another critical benefit of Geberit’s in wall system, especially in the San Francisco area where environmental considerations are important, is the dual-flush option. For dual-flush toilets, there’s typically a 2:1 usage ratio between the liquid waste mode of 0.8 GPF (3 LPF) and the full flush of 1.6 GPF (6 LPF). If the full flush is used once a day, and the reduced flush is activated twice, that brings the total water use to 3.2 gallons per day or 1,139 gallons per year. That’s a 33% water savings compared to 1.6 GPF flushing only.
