TOTO CST646CEMFGNAT40 Technologies and Benefits:
CEFIONTECT®: The nano-scale glaze that creates a super-smooth, ionized barrier, which prevents particles from adhering to porcelain, reducing the need for harmful cleaning agents.
DYNAMAX TORNADO FLUSH®: Uses 100% of water to clean and rinse the bowl using a smaller amount of water more efficiently with a 2.5” trapway and quieter flush. Available in 1.0/.9 GPF or 1.28/.8 GPF.
Universal Height: Toilet height that allows for a more comfortable height position across a wide range of users.
Skirted Design: The Skirted Design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. Skirted Design toilets also minimize the need to reach behind the bowl to clean the nooks and crannies of the exterior trapway.
