The lack of a flush handle is the first thing you might notice on the Aquia toilet from Toto.
Push buttons on top of the water tank allow the user to choose a .9 gallon flush for liquids or a 1.6 gallon flush for solids.
Those unhappy with the performance of standard 1.6 gallon per flush toilets might wonder why anyone would want a toilet that uses even less water. But the fixtures are common and popular in other countries. If blogs are any indication, the Toto Aquia seems to have many satisfied users in this country.
The Aquia employs a "wash down" flush: Water pushes waste out of the bowl through a large (2-1/8") trapway. Traditional toilets, including the 1.6 gpf models required since 1994, siphon waste through a smaller trapway. Like all wash down toilets, the Aquia has a smaller waterspot (the amount of standing water in the bowl) than most Americans are used to.
The two-piece Aquia features a sleek European-style elongated skirted design. If you're installing the toilet in an existing bathroom, be aware that the floor profile may not match that of the toilet you're replacing.
Installation can be a bit tricky for novices. The toilet requires an adapter and six holes for bolts (rather than the standard two). Although the toilet requires 12" of rough-in space, its total bowl profile is 27-1/2" from front to back.
The toilet is WaterSense certified by the Environmental Protection Agency, meaning it is at least 20 percent more efficient than standard 1.6 gpm toilets.
