TOTO MS446124CEMGN#01 Aquia® IV Toilet – 1.28 GPF & 0.9 GPF, Elongated Bowl – WASHLET+ Connection – New

The Toilet That Thinks Before It Flushes

Most toilets use the same amount of water every time. One flush for everything. That wastes water on liquid waste and sometimes leaves solid waste behind. The TOTO Aquia IV does something smarter. It gives you two flush options. Press one button for 0.9 gallons. Press the other for 1.28 gallons. The choice belongs to you. The result is less water used and a cleaner bowl every time.

This is not a gimmick. It is engineering. The dual flush system works because the DYNAMAX TORNADO FLUSH technology makes every drop count. Water enters the bowl through multiple nozzles and swirls in a 360-degree pattern. The entire surface gets rinsed. Nothing gets left behind. The flush is quiet but complete.

What DYNAMAX TORNADO FLUSH Actually Does

The name sounds dramatic. The function is simple. Water enters the bowl from multiple points instead of one. The water swirls around the entire bowl, washing every surface. The rim, the sides, the bottom. Everything gets cleaned. Traditional toilets push water down from one spot. The TORNADO FLUSH covers the whole bowl. This matters when you want a clean toilet without scrubbing after every use.

The system also reduces clogs. The 2.5-inch fully glazed trapway allows waste to pass through without catching. The smooth glazed surface prevents debris from sticking. The result is a toilet that flushes completely the first time. No plunger beside the toilet. No embarrassing second flush.

The Glaze That Keeps the Bowl Cleaner

TOTO uses a ceramic glaze called CEFIONTECT. The surface is incredibly smooth. Waste, mold, and bacteria cannot grip the surface. They slide away with each flush. The bowl stays visibly cleaner between cleanings. You scrub less. You use fewer chemicals. The toilet looks better with less effort.

For busy households in Mississauga and Brampton, this matters. For rental properties in Ottawa and Halifax where tenants may not clean often, the CEFIONTECT glaze keeps the toilet presentable. For anyone who hates cleaning toilets, this feature alone justifies the investment.

The Skirted Design That Removes the Hidden Dirt

Standard toilets have a visible trapway with curves and crevices. Dust collects there. Dirt settles in the grooves. Cleaning around the base means bending and reaching into awkward spaces. The Aquia IV uses a skirted design that hides the trapway. The sides are smooth and flat. A quick wipe cleans the entire exterior. The streamlined silhouette looks modern. The cleaning is faster. The toilet stays cleaner with less effort.

WASHLET+ Ready Means Futureproof

The Aquia IV is WASHLET+ ready. This means the toilet is compatible with TOTO’s electronic bidet seats. You can add a WASHLET now or later. The connection is built in. The installation is clean. No exposed wires. No awkward adapters. If you are not ready for a bidet seat today, you can upgrade tomorrow without replacing the toilet.

This matters for homeowners in Calgary and Edmonton who want to futureproof their bathroom. It matters for anyone considering a smart toilet but not ready to commit. The Aquia IV gives you the option.

Comfort Features That Make a Difference

The elongated bowl provides more seating surface than a round bowl. The shape supports the body better. The universal height sits slightly higher than standard, making it easier to sit down and stand up. The SoftClose seat closes slowly and quietly. No slamming. No pinched fingers. No noise in the middle of the night.

The chrome dual push button adds a modern touch. The buttons are easy to press. The action is smooth. The design feels intentional.

Installation Flexibility for Canadian Homes

The Aquia IV comes with a 12-inch rough-in as standard. This matches most Canadian homes built in the last fifty years. Optional 10-inch and 14-inch rough-ins are available for different plumbing configurations. This matters for older homes in Toronto and Montreal where the drain may sit closer to the wall. The flexibility allows plumbers and contractors to work with existing plumbing without modification.

Where the Aquia IV Belongs

The skirted design looks modern and clean. The WASHLET+ compatibility adds future value. The SoftClose seat comes included.
