The Studio S Chair Height Low-Profile Toilet from American Standard is a sleek, tankless design that complements the contemporary aesthetic of the Studio S Collection. This clean, unobtrusive toilet boasts advanced features that similar low-profile models lack, including our innovative PowerFlo flushing technology. This powerful, water-saving system uses just 1.0 gallon per flush to completely clear the bowl the first time. Studio S is quieter than most comparable toilets, requires no batteries or electrical power, and uses a standard bathroom inlet water connection.
