We’ve seen wall-hung toilets for years in airports, stadiums, hospitals and office buildings. These applications were pressure assist driven, in that they drew water pressure and power from the piping behind the wall. These are still the leading applications for wall hung toilet installations.
As high rise structures were being built, the change from horizontal under-floor piping to vertical in-wall piping drove the need for wall hung toilets in residential/homeowner oriented spaces, explains Lovin Saini, senior product manager for Gerber Plumbing Products.
