TOTO Ultramax vs Ultramax II: What's the Difference?

You may know about TOTO already—it’s one of the most trusted names in the toilet industry. Specifically, their Ultramax series has a reputation for durability and efficiency. 

But zooming in even further, how are you going to choose between two of its key products, the TOTO Ultramax vs. Ultramax II?

Both models are among TOTO’s top-rated options, but they do cater to slightly different needs. 

That’s why this guide will compare their design, flushing systems, efficiency, and overall value so you can make a more informed choice.

Toto Ultramax II vs. Ultramax: Key Differences and Similarities

First things first: you can’t go wrong with either of these options. It’s not as if one toilet is “good” and the other is “bad.”

Both fixtures come from a leading toilet provider, and both have qualities that help distinguish these options from “budget” toilets on the market. That said, they definitely have some key differences. 

So what is the difference between the TOTO Ultramax and Ultramax II? 

It comes down to these key factors:

1. Design
2. Flushing technology
3. Water efficiency
4. Convenience

Design and Build Quality

The Toto Ultramax 1 vs. 2 models have some things in common. They’re similarly sleek, with a one-piece design, which makes them easy to both clean and maintain. Both also offer different finishing options so you can customize the overall look and aesthetics of your bathroom.

The dimensions are also pretty similar. Most Ultramax are offered as ADA height compliant, although the round version only has a  seated height of 15.69".

The TOTO Ultramax II always features a Universal Height bowl, making it highly accessible and a great option for a guest bathroom where you never know who’s going to use it.

TOTO's Universal Height is a minimum 16.5" but all of the newer Ultramax II toilets are at least 17" seated height, making them ADA compliant as well. 

Flushing Technology

The original Ultramax uses TOTO’s G-Max flushing system, which uses an extra-large siphon jet to squeeze as much power out of your efficient gallon-per-flush numbers. 

The original Ultramax is pictured below

The Ultramax II features the upgraded Tornado Flush (formerly called Double Cyclone Flush), using two nozzles to create cyclonic flushing action.

If you’re wondering which TOTO flushing system is the best, we like the cyclonic Tornado Flush system better. It offers less noise and water usage while packing a wallop of a flush. 

Water Efficiency

Efficiency of water usage is always the name of the game with TOTO systems. The TOTO Ultramax II is WaterSense certified at only 1.28 gallons per flush (GPF). If you’re extra eco-conscious, this is a fantastic option.

The upgraded Ultramax II is featured below 

The Ultramax comes in at a slightly higher 1.6 GPF, meaning that while it meets regulations and you won’t have to feel guilty about using it, it’s simply not going to offer the same kind of efficiency you’ll get out of the “II.” 

However, the Eco Ultramax does feature a 1.28 GPF if you’re looking for something more water efficient.

Comparing these key TOTO Ultramax vs. Ultramax II specs gives us more to work with when making a decision.

Comfort and Usability

Honestly, they both perform well here. Both the Ultramax and Ultramax II feature an elongated bowl. Universal height seating makes them ADA-compliant and anyone with mobility concerns is going to find that useful. 

And since both toilets are capable of handling TOTO’s soft-close seat and Washlet bidet attachments, you’ll get as much extra convenience, comfort, and hygiene benefits as you prefer.

TOTO Ultramax vs. Ultramax 2: Specific Features to Highlight

Installation Details

Both the TOTO Ultramax and Ultramax 2 are designed for easy installation—you’re not going to stress yourself out as these toilets go into your bathroom. They’ll fit the standard rough-in plumbing setups, which makes them a cinch to get going.

Additionally, the one-piece construction makes sure that the process is even simpler than two-piece toilets.

Maintenance and Cleaning

TOTO’s maintenance and cleaning are usually straightforward. We like the Ultramax II here, as its CEFIONTECT glaze helps prevent waste from sticking to the bowl. No need for extra-harsh chemicals—you can simply clean it down occasionally and expect great results.

The Ultramax may not come with CEFIONTECT by default, so make sure to double-check that if you want it as an option. It’s definitely worth the extra investment.

Long-Term Savings and Value

So far, things are weighing pretty well on the Ultramax II side of things. What about long-term savings and value? Do those change the equation over time?

If you ask us, the TOTO Ultramax II price may be slightly higher upfront, but it tends to save money on water bills in the long run thanks to its more efficient flushing system.

The Ultramax, of course, may not be as water-efficient, but it’s still durable and reliable. The flush is powerful, and as a slightly lower price entry point, it makes sense for anyone who’s furnishing a home on a budget and needs a quality toilet ASAP.

TOTO Ultramax II vs Ultramax: Pros and Cons

TOTO Ultramax

Pros:

• Powerful G-Max flushing system
• Slightly lower initial cost
• Reliable and durable design

Cons:

• Uses more water (1.6 GPF)
• Lacks CEFIONTECT glaze, which would make cleaning easier

TOTO Ultramax II

Pros:

• WaterSense-certified at 1.28 GPF
• Tornado Flush offers quieter, more efficient flushing
• CEFIONTECT glaze helps cleaning and maintenance
• More eco-friendly and cost-efficient in the long run

Cons:

• Slightly higher upfront cost

Final Recommendation

If you’re on a budget, you have to weigh whether you want to pay a lower upfront cost for the Ultramax vs. the lower long-term costs and efficiency of the Ultramax II. 

And are the tradeoffs for the Ultramax really worth it if you want an easier-to-clean bowl with more efficient flushing? Only you can decide. But let’s zoom out for a final verdict. 

Here’s what we recommend:

Choose the Ultramax if your chief emphasis is flushing power and a lower upfront cost. Maybe those are the factors are the ones that matter most to you—and if so, you can’t go wrong with an Ultramax.

Choose the Ultramax II if you want better water efficiency, quieter flushing, and easier cleaning. These aren’t small details when it comes to toilets, after all. And if you want a toilet that continues to earn its keep throughout the years, the Ultramax II is clearly the choice here.

And finally, you have to consider where you live. What if you live in an area with water restrictions? Or an area with high utility bills? Here, the TOTO Ultramax II is likely your better investment. 

On the other hand, you might need a traditional high-powered flush so you can continually rely on your toilet to offer that. If you don’t mind the extra water usage—and a little bit more in the cost-per-flush thanks to it—the Ultramax original remains a solid choice for you.

Conclusion: The Ultramax vs Ultramax II

Both the TOTO Ultramax vs. Ultramax II models are excellent toilets. Top-tier performance, excellent durability. You won’t go wrong if you flip a coin.

But your decision should also depend on whether you value flushing power (Ultramax) or water efficiency and ease of maintenance (Ultramax II).

Ultimately, TOTO’s reputation for high-quality toilets is a comfort no matter what you choose. So it comes down to what you prefer. If you’re eco-conscious? The Ultramax II is likely up your alley. If you’re budget-conscious, you have to make a choice about the lower upfront cost of the Ultramax vs. the long-term savings of the Ultramax II.

Consider your priorities, match them up with the toilet that suits you, and pick the model that fits your home.
