TOTO Drake II Two-Piece Toilet vs TOTO UltraMax II One-Piece Toilet: Which Should You Buy?

Both the TOTO Drake II and TOTO UltraMax II have a MaP score of 1000g, meaning they can flush up to 1000 grams of solid waste in a single test. For context, the industry standard for a good toilet is 350g, and a score of 600g is considered excellent. A MaP score of 1000g means both models can handle heavy waste loads without clogging. They use the same Double Cyclone flush system and 3-inch fully glazed trapway, so flush power is identical. Neither toilet has an advantage here; both are among the most powerful residential toilets available.

Both toilets use 1.28 gallons per flush (GPF) and are WaterSense certified by the EPA. This means they use 20% less water than the federal standard of 1.6 GPF while still providing effective waste removal. Since both models have identical GPF and WaterSense certification, water savings are exactly the same. Over a year, either toilet will save approximately 4,000 gallons of water compared to an older 3.5 GPF model. Neither one saves more water than the other.

The TOTO UltraMax II One-Piece Toilet is better for easy cleaning because its one-piece design eliminates the seam between tank and bowl where dirt and bacteria can accumulate. The Drake II's two-piece construction has a visible seam that requires extra scrubbing. Both models feature CEFIONTECT glaze, a permanent ceramic finish that prevents waste from sticking, reducing the need for frequent cleaning. However, the UltraMax II's seamless profile makes it significantly easier to wipe down and maintain over time.
