Spec-by-Spec Comparison
Detailed Comparison
The TOTO Aimes and UltraMax II are both premium one-piece TOTO toilets with identical flush technology (Tornado Flush + CeFiONtect glaze), identical 1.28 GPF rating, and identical universal-height seat. The choice between them is decor-driven.
Design language
The Aimes ($900-1,000) is the cleanest contemporary minimalist design in the TOTO lineup — knife-edge bowl, geometric tank profile, narrow footprint. The UltraMax II ($790-850) is the all-arounder — rounded tank, traditional toilet silhouette executed cleanly, fits any bathroom style from modern to transitional.
Footprint and proportions
The Aimes is the narrowest TOTO one-piece (28-inch projection vs 28.5 for UltraMax II) — meaningful in tight powder rooms. Both are comfort-height (17 inches), both elongated. The Aimes tank is shorter and squarer; the UltraMax II tank is taller and slimmer.
Functional performance
Flush performance is indistinguishable. MaP score 1,000g on both. Both use TOTO's Class Five flush valve with SoftClose seat included.
Decor flexibility
The UltraMax II's traditional silhouette works in any bathroom remodel — traditional, transitional, contemporary all fit. The Aimes commits to a contemporary aesthetic; in a traditional bathroom remodel, the angular form can read as deliberately out-of-place rather than complementary.
Price and resale
The Aimes premium is justified primarily by the contemporary design statement. For decorative-led purchases (full bathroom remodels around a modern theme), the Aimes earns its premium. For replacement-only scenarios where matching the existing bathroom design is more important, the UltraMax II is the safer, less-committed choice.
Final Verdict
We recommend the TOTO UltraMax II for traditional and transitional bathrooms where decor flexibility matters — it costs less and fits any design. The Aimes makes sense only when contemporary minimalism is the deliberate design priority and the bathroom is built around frameless glass, large-format tile, and angular fixtures.
