TOTO CST744SL Drake 2-Piece Ada 1.6 GPF Toilet


When we talk about no-clog toilets for big stools, this model by TOTO takes the first spot. The single flush elongated two-piece comfort height toilet by TOTO has a high-profile design with a fully glazed trap way. In addition, it has a sleek and smooth look that matches well with modern furnishing.

The flagship of TOTO Drake is its GMAX flushing system that is one of the best in flushing technology. TOTO’s GMAX flushing system encompasses a 3” wide flush valve, extra-large siphon jet, and a 2-1/8 inch fully glazed trap way for better cleaning. Drake is a single flush toilet and uses as little as 1.6 gallons of water per flush. Its extra-large siphon jet forces water into the bowl at a rapid speed to create a powerful flush that can easily flush out your massive turds.

These no-clog toilets for big stools are ADA-compliant and possess a height of 16.5 inches. This height is from the base of the toilet to the top of the toilet bowl, without a seat. This ADA toilet proves to be a good match for people with disabilities or knee problems. Senior citizens will also find TOTO Drake easier and sit on and get up from.

You can install it in both residential and commercial areas as the model is durable enough. One drawback that TOTO CST744SL Drake has is since it uses 1.6 gallons of water per flush, it is not WaterSense certified. So, it cannot be sold in places like California.

Like the rest of the American Standard’s products, the Champion 4 also includes its revolutionary Ever Clean surface, that’s easy to clean and stays clean for long.

It has a standard design, with two pieces and no interesting styling cues adding to its flair.

First and foremost, the tank is noise canceling. It helps in preventing any sound from escaping into the bathroom. So, instead of emptying all the way every time it is flushed, the tank remains mostly full, using only a small portion of the water inside for a flush. This allows the valve to remain submerged, which prevents any sound there is from transferring out of the tank.

This toilet is a test made to make a high hardness flush, and other efficient toilets are also certified by ADA which means that the Niagara Stealth can be installed for use in public toilets, used by employees or the general public.


  • Ultra-High-Efficiency Flush
  • Uses just 0.8 gallons per flush (GPF)
  • Water Sense certified.


The only drawback with the Niagara Stealth is that it does not come with the bolts to attach the toilet to the floor.
