TOTO UltraMax II One-Piece Elongated Toilet — MS604124C
The TOTO UltraMax II is a sleek, one-piece elongated toilet engineered for high-efficiency performance and long-term ease of maintenance. Designed to TOTO's Universal Height standard, it delivers a comfortable seat position for a wide range of users and meets ADA, EPA WaterSense, CEC, and CALGreen requirements — making it a compliant choice for commercial, multi-family, and residential projects alike.
TORNADO FLUSH System
The UltraMax II uses TOTO's TORNADO FLUSH — a hole-free rim design with dual nozzles that generates a powerful centrifugal washing action, rinsing the bowl more thoroughly with just 1.28 GPF (or 1.0 GPF on select variants). The hole-free rim eliminates the hard-to-clean ledge found on conventional toilets.
CEFIONTECT Glaze (Select Variants)
Certain configurations include TOTO's CEFIONTECT — an ultra-smooth ceramic glaze that minimizes waste adhesion to the bowl surface. Combined with TORNADO FLUSH, CEFIONTECT reduces cleaning frequency and the need for harsh chemicals. CEFIONTECT availability varies by variant; confirm your selection at checkout.
One-Piece Design Benefits
The seamless one-piece construction eliminates the tank-to-bowl gap where dirt and debris accumulate in two-piece toilets, and removes the bolts and gaskets that are common leak points. The result is a cleaner profile and a lower long-term maintenance burden.
WASHLET+ Ready
The UltraMax II features a channel on the bowl surface designed to conceal the supply line and power cord of an optional TOTO WASHLET+ bidet seat, enabling seamless integration without exposed wiring.
