With the Eco QUATTRO™ flushing system, St. Thomas Creations water closets offer an unrivalled combination of flushing power, exceptional cleanliness with a minimum of water usage.

Powerful, Quiet Flush

Eco QUATTRO toilets deliver extraordinary bulk flushing power, more than enough for any residential or commercial need. An extra-large direct-fed water jet, with an oversized 2-1/8" glazed trapway, virtually eliminates clogging. As a result, St. Thomas Creations toilets are independently certified to flush 800-1000 grams of solids in MaP tests, far surpassing the industry average of 400 grams. Meanwhile, toilet flushing is quiet, for added privacy and comfort.

Bowl Cleanliness

St. Thomas Creations's toilet bowls feature a large water surface area (minimum of 9" x 7"), which is noticeably larger than those in most toilets. This is important for maintaining bowl cleanliness, and avoiding stains during use.

Furthermore, St. Thomas Creations rim jets are designed and optimally placed for an exceptionally clean rinse of the bowl surface. With oversized 3-inch flush valves delivering maximum water flow to the bowl, St. Thomas Creations toilets end the need for double-flushing.

Water Conservation

Using less than 1.28 gallons (4.8 liters) per flush, St. Thomas Creations offers the most efficient, water-saving toilets available. St. Thomas Creations's High-Efficiency Toilets (HET) are certified EPA WaterSense™ compliant, and use 20–60% less water than the average installed toilet (which typically use 1.6–3.5 gpf).
