TOTO Drake II Two-Piece Elongated 1.28 GPF Toilet vs TOTO UltraMax II One-Piece Elongated 1.28 GPF Toilet

Both toilets use TOTO Tornado Flush and CeFiONtect glaze — identical flush performance. The choice between them is structural: two-piece vs one-piece. The Drake II ($480-560) bolts a separate tank onto the bowl with a spud gasket between them; the UltraMax II ($790-850) fuses tank and bowl into a single ceramic body. Practical impact: the one-piece eliminates the tank-bowl gasket leak risk that emerges at year 8-15 on every two-piece toilet, presents a cleaner visual line, and wipes flat across the joint where two-piece accumulates grime. Trade-offs: the UltraMax II weighs 30+ pounds more (harder to install solo), costs significantly more upfront, and if shipping damages the bowl, you replace the whole unit rather than just one half. For households cleaning weekly, the UltraMax II saves about 15 minutes per cycle over the toilet's 20-year life.
