Toto Drake II vs Ultramax II : Detailed Comparison

Flush Performance

The most important consideration when choosing any toilet is the flushing performance. Both the Toto Drake II and Ultramax II feature Toto’s powerful double cyclone Tornado Flush technology. This generates a strong siphon during flushing to rinse the bowl thoroughly.

The key stats on flush performance for both models:

  • Water usage: 1.28 gallons per flush (GPF)
  • Gravity flush: Uses the force of gravity and a precision-engineered tank, bowl, nozzles, and siphon design to create a fast, effective flush. No need for high water pressure.
  • Double cyclone flush: Dual nozzles generate a centrifugal washing action that cleans the rim and bowl thoroughly.
  • Quiet operation: Uses a 3″ flush valve and extra-large siphon jet to optimize flushing flow. This allows more water to pass through the system quickly while reducing noise.
  • Powerful, effective cleaning: Both models have received a maximum 500 gram MaP (Maximum Performance) score for waste removal. This means they can flush away mass waste in one flush without clogging.

With their efficient 1.28 GPF gravity flushes and centrifugal cleaning action, both the Drake II and Ultramax II offer industry-leading flush capabilities in high efficiency toilets. When it comes to flush power and bowl cleaning, the models are evenly matched.

Water Savings

In addition to flush power, water conservation is a top priority for many homeowners shopping for a new toilet. The Drake II and Ultramax II both qualify as EPA WaterSense certified high efficiency toilets.

Here is how they can help you save water:

  • 1.28 GPF water usage: By using 20% less water than a standard 1.6 GPF toilet, these HET models can save you up to 4,000+ gallons per year without sacrificing performance. This can lead to significant water bill savings over time.
  • WaterSense certified: WaterSense toilets must complete rigorous third-party testing to prove reduced water usage. Choosing a WaterSense model ensures reliable water savings.

If water conservation is your main aim, you can count on either the Toto Drake II or Ultramax II to help you use water wisely while still flushing with power.

Design and Dimensions

While the Drake II and Ultramax II share efficient flushing systems, their designs are quite different. Here is how they compare:

Bowl shape

  • Both models feature an elongated bowl design which offers more comfortable seating than a round bowl.

Toilet height

  • The Drake II and Ultramax II are both comfort height toilets, measuring 16-1/2” from floor to seat top. This chair height makes sitting down and standing up easier for most adults.

Toilet dimensions

  • Toto Drake II: 28 x 19.5 x 30.5 inches
  • Toto Ultramax II: 28.3 x 16.6 x 28.8 inches

The Ultramax II has a slightly smaller footprint, with the tank integrating more seamlessly into the bowl design. The Drake II has a more traditional tank and bowl appearance.

One-piece vs two-piece design

  • The Ultramax II features a streamlined, easy to clean one-piece design.
  • The Drake II has a standard two-piece configuration with the tank and bowl as separate sections.


  • Drake II: Cotton, Sedona Beige, Bone, Colonial White
  • Ultramax II: Cotton White, Sedona Beige, Bone

The Drake II offers an additional Colonial White color option for a total of four choices.

  • The Ultramax II has a very sleek, contemporary style.
  • The Drake II has a more classic, traditional design.

To sum up the key design differences:

  • The Ultramax II is more compact and has a seamless one-piece look.
  • The Drake II has a larger footprint and classic two-piece tank and bowl styling.
  • Both models come in three neutral, versatile colors like Cotton White and Bone.
  • Choose the Ultramax II if you want a space-saving one-piece toilet with a modern style. Go with the Drake II if you prefer the traditional tank and bowl design.


In addition to the elongated bowl found on both models, the Drake II and Ultramax II offer other comfort-enhancing features:

  • Chair height seating: The right height to make sitting down and standing up easier for most adults. Reduces strain on joints.
  • SoftClose Seat: The toilet seat closes slowly and quietly with a gentle push instead of loudly slamming down.
  • Automatic Open/Close Lid: The Ultramax II takes the SoftClose seat a step further with a lid that opens automatically when you approach the toilet and closes when you step away. Provides added convenience and hands-free operation.

Both toilets promote proper toilet posture and reduce strain with their chair height and elongated bowl. The Ultramax II offers the most convenient, automated seat functionality, while the Drake II provides effective SoftClose to prevent seat slam.

Ease of Installation

Installing the Toto Drake II or Ultramax II is straightforward, especially for general DIYers with some plumbing experience. Here is what to expect:

  • 12” rough-in: Designed to fit standard 12” rough-in bathroom plumbing for easy retrofitting.
  • Floor mount: The two-piece Drake II has a standard floor mount with closet bolt holes. The one-piece Ultramax II uses a proprietary mount system that secures to the floor.
  • Basic tools needed: Adjustable wrench, screwdriver, plumber’s putty, tape measure.
  • Quick install: countertop removal may be required.
  • Compatible with any flush valve supply line: Connects to water supply line from wall or floor.

The steps are very similar for both models. Shut off water supply, remove old toilet, install closet bolts, set bowl, connect water line, install tank, seal base, attach seat. No special work needed.

Overall the Drake II and Ultramax II offer uncomplicated installation ideal for DIYers. The Ultramax II one-piece design may have a slight learning curve but Toto provides clear instructions.


As you shop for these Toto toilets, price is often a consideration. Here is an overview:

  • Toto Drake II cost: Approximately $300-$450

These convenient features come at a higher price point.
