TOTO UltraMax II One-Piece Toilet Review: Premium Flush Power Meets Seamless Cleaning

How powerful is the TOTO UltraMax II flush?

The MaP (Maximum Performance) testing program is the industry standard for measuring toilet flush effectiveness. A score of 1000g means the UltraMax II can handle the heaviest waste loads without clogging or requiring multiple flushes. This performance is delivered through TOTO's Double Cyclone flush system, which uses two powerful nozzles to create a centrifugal washing action inside the bowl. Unlike traditional siphon jets that can clog over time, the Double Cyclone system has a wider, more direct water path that maintains consistent performance.

The 3-inch fully glazed trapway further enhances this capability. A larger trapway reduces the chance of blockages, and the full glaze ensures waste slides through smoothly without catching on rough surfaces. Many owners report that the UltraMax II handles everything from heavy family use to occasional high-volume situations without hesitation. The flush is also notably quiet compared to older pressure-assisted models, making it suitable for bathrooms near bedrooms or living spaces.

How water-efficient is the TOTO UltraMax II?

WaterSense certification from the EPA ensures the toilet meets strict criteria for both water consumption and performance. Toilets bearing this label must complete a MaP test with a score of at least 350g, but the UltraMax II far exceeds this minimum with its 1000g rating. This means you get maximum water savings without the common complaint of weak flushes often associated with low-flow toilets.

For a household of four, switching from a 1.6 GPF toilet to the UltraMax II can save roughly 2,000 to 3,000 gallons of water per year, depending on usage patterns. The 1.28 GPF rating also qualifies for many local water rebate programs, which can offset the initial purchase cost. The CEFIONTECT glaze further contributes to efficiency by creating a super-smooth surface that resists waste adhesion, reducing the need for extra flushes or aggressive cleaning.

What do owners say about the TOTO UltraMax II?

Aggregated feedback from multiple retailers reveals several recurring themes. The most frequently mentioned positive is the flush performance. Owners describe it as "powerful," "efficient," and "rarely needs a second flush." Many specifically note that it handles large waste volumes without clogging, which is a key concern for families and households with heavy usage.

The one-piece design is another major selling point. The seamless body eliminates the crevice between the tank and bowl where dirt and bacteria can accumulate. Owners appreciate how easy it is to clean the entire exterior with a single wipe. The CEFIONTECT glaze also receives positive mentions for preventing waste from sticking, though some note it still requires occasional scrubbing.

On the negative side, the lack of an included seat is a common complaint. Buyers must purchase a separate seat, which adds to the total cost. Some owners also mention that the universal height (17.25 inches) may feel too tall for shorter individuals or children. A few reviews note that the toilet can be noisy during the refill cycle, though the flush itself is generally described as quiet.

How does the TOTO UltraMax II compare to similar toilets?

When compared to the Kohler Santa Rosa, another popular one-piece toilet, the UltraMax II has a clear advantage in flush performance. The Santa Rosa typically achieves a MaP score around 800g to 900g, while the UltraMax II reaches 1000g. Both use similar water consumption (1.28 GPF), but the UltraMax II's Double Cyclone system and 3-inch trapway provide more reliable waste handling. The Santa Rosa, however, often comes at a lower price point and includes a seat in some configurations.

Against two-piece toilets like the TOTO Drake II, the UltraMax II offers a more streamlined appearance and easier cleaning due to the one-piece construction. The Drake II also uses a 1.28 GPF flush and has a similar MaP score, but the two-piece design creates a seam that can trap dirt. The UltraMax II's CEFIONTECT glaze is also superior to the standard glaze found on most two-piece models. The trade-off is cost: the UltraMax II is typically more expensive than comparable two-piece toilets.

For budget-conscious buyers, the American Standard Champion 4 offers a 1.28 GPF flush with a MaP score around 1000g, but it is a two-piece design and lacks the premium glaze of the UltraMax II. The Champion 4 is also taller (17.5 inches) and has a slightly different bowl shape.
