The Studio® S Right 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 gpf 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.
