Toilet Types
Which toilet type is best for you?
Water Saver
Ultra-Low-Flow (ULF)
High-Efficiency (HET)
Single-Flush
Single-flush toilets have just a single flush volume option. Some models flush with as little as 0.8 gallons (3.0 litres), and some flush with as much as 1.6 gallons (6.0 litres). Models certified to WaterSense flush with no more than 1.28 gallons (4.8 litres). Search single-flush here.
Dual-Flush
Gravity-Fed

Siphonic
Wash-Down
Pressure-Assist
Pressure-assist toilets store water used for flushing in a pressure vessel at the same pressure as the building’s water supply – typically between 40 to 80 psi. Water filling the pressure vessel – which is typically housed inside a traditional-looking vitreous china toilet tank – compresses air contained in the tank. It is the pressure of that compressed air that quickly forces water from the tank into the bowl when the flush lever is pushed. Because water is stored in a pressure tank rather than a vitreous china tank, pressure-assist toilets do not “sweat” even in humid climates. While pressure-assist toilets offer a robust flush action, compared to gravity models they can sometimes be more expensive to purchase, more difficult to repair, and louder.
Round-Front vs. Elongated Bowl Design
Today’s toilets come with either a smaller, round-front bowl or a longer, elongated-front bowl. Round-front bowls were very popular in the 1900s and are still ideal for compact bathroom spaces today. Elongated bowls are commonly installed today because they are considered more comfortable for adult use and more hygienic. Plumbing codes require the use of elongated bowls in commercial applications. Search bowl choice here.
