TOTO Drake vs TOTO Ultramax: Which Toilet Is Better?

Two proven families from TOTO

TOTO's Drake and Ultramax are two of the company's most widely used toilet families. Both have a strong reputation for reliable gravity flushing and efficient water use, but they differ in design details that can affect comfort and installation. This comparison focuses on flush performance, bowl shape, and dimensions, which are the three factors buyers typically weigh first.

Before comparing, remember that neither name refers to a single model. TOTO offers multiple Drake and Ultramax configurations, each with its own set of specifications. You should always check the spec sheet for the exact model you're considering, and if you haven't already, learn how to read those sheets by reviewing how to read toilet specs.

Flush performance and efficiency

Both the Drake and the Ultramax are designed around gravity siphonic flushing, a system that uses water weight and a siphon formed in the trapway to pull waste from the bowl. This is the most common flushing mechanism in residential toilets and is generally reliable and quiet. Neither family is marketed as pressure-assisted, so you should expect gravity performance rather than the stronger push of a pressure-assist system.

For water efficiency, the U.S. Environmental Protection Agency's WaterSense program sets a maximum flush volume of 1.28 gallons per flush for labeled toilets. According to the EPA, WaterSense labeled toilets use 20 percent less water than the current federal standard of 1.6 gallons per flush, while still meeting rigorous performance requirements. When comparing Drake and Ultramax models, look for the WaterSense label, and for dual-flush versions, check the reduced flush volume. A dual-flush option can save even more water, as the EPA notes that choosing a reduced flush mode for liquid waste uses a smaller volume.

Bowl shape: round vs elongated

Bowl shape is one of the most visible differences between the Drake and Ultramax families. The Drake has traditionally offered both round and elongated bowls, while the Ultramax leans heavily toward an elongated, taller profile. Elongated bowls provide more seating surface and are often more comfortable for adults, but they require more front-to-back clearance in the bathroom.

If your bathroom has limited space, a round bowl may fit better, and the Drake family is a good candidate because it includes compact round models. On the other hand, if comfort is your priority and you have at least a few extra inches, an elongated bowl is usually preferred. The Ultramax is generally associated with elongated designs, so it may be the better match for those who want that shape without hunting for a specific configuration.

For a detailed discussion of how bowl shape affects comfort and space, read round vs elongated toilets. Also consider the seat: elongated toilets take a correspondingly larger seat, so you will need to purchase the correct seat size if you plan to upgrade.

Dimensions, rough-in, and height

Dimensionally, the Drake and Ultramax families overlap, but the Ultramax often has a slightly taller bowl height, which can make sitting down and standing up easier. Chair height toilets, typically around 16 to 17 inches from floor to seat, are common in both families. However, you should verify the exact height of the model you are considering because it will affect comfort, especially for elderly users or those with mobility issues. The Americans with Disabilities Act (ADA) sets specific technical requirements for accessible toilets, and while those standards apply to public facilities, many people choose residential toilets with similar dimensions for comfort. Review the ADA toilet requirements to understand what a taller bowl typically entails.

Rough-in distance, the horizontal length from the finished wall to the center of the toilet flange, is a critical dimension. Most residential toilets use a 12-inch rough-in, but 10-inch and 14-inch options exist. Neither the Drake nor the Ultramax is universally limited to one rough-in; you must check the model's specification. If you are replacing an older toilet, measure your rough-in before ordering. The toilet rough-in measurement accuracy article explains how to get it right.

The overall footprint also matters. A longer bowl, wider tank, or skirted design can affect how closely the toilet sits to the wall and how easy it is to clean. The Ultramax is sometimes skirted, which means the trapway is concealed behind a smooth surface, making cleaning easier. For more on this, see skirted toilets explained.

Design, comfort, and everyday use

Beyond flushing and dimensions, the feel of the toilet in daily use comes down to a few other factors. The height of the bowl affects posture, and a taller bowl can be more comfortable for taller people. The shape of the bowl (round vs. elongated) influences how much room you have. The tank style can change both appearance and how far the toilet extends from the wall.

Water quality and maintenance also play a role. Both families are made of vitreous china and receive a glazed finish, but the quality of that finish can affect how easily stains and bacteria cling. TOTO's glazes are generally well regarded, but you should evaluate the trapway and rim design. For insight on glaze, read evaluating toilet glaze quality.

How to choose between Drake and Ultramax

Start by measuring your bathroom and determining your non-negotiables: bowl shape, height, rough-in, and whether you want a one-piece or two-piece construction. Both families come in one-piece and two-piece styles, but the specific model you pick will decide that.

If space is tight, a round bowl from the Drake family might be the safer fit. If you want a taller, more elongated seat and are willing to give up a few extra inches of floor space, the Ultramax is often the better choice. But these are generalizations; confirm the exact dimensions of the models you shortlist.

Remember, the right choice is the one that fits your measurements and your comfort. Do not rely solely on the family name; always verify the spec sheet.

Questions

Are TOTO Drake and Ultramax toilets the same?

No, they are different families with distinct designs. The Drake is often more compact and offers round bowls, while the Ultramax generally has a taller, elongated profile and sometimes uses a skirted design. However, both are gravity siphonic toilets and both have models that meet WaterSense efficiency standards.

Which has a better flush, Drake or Ultramax?

Both use the same gravity siphonic mechanism, so flush performance is comparable when the models have similar trapway size and rim design. The exact performance depends on the specific model, not just the family name. Look for WaterSense certification, which indicates the toilet meets EPA performance criteria.

Do Drake toilets come in elongated bowls too?

Yes, some Drake models are elongated, but the family is known for including round-bowl options. If you prefer an elongated bowl, check the model specifications before buying.

What is the rough-in size for TOTO Drake and Ultramax toilets?

Rough-in size varies by model. Most residential TOTO toilets use a 12-inch rough-in, but 10-inch and 14-inch options exist. Always measure your rough-in distance before selecting a toilet.

Are TOTO Drake and Ultramax toilets ADA compliant?

Some models in both families have ADA-compliant heights, but not all. The ADA standards define a seat height range for accessible toilets. Check the individual model specification to see if it meets ADA guidelines.

Is one toilet more expensive than the other?

Pricing depends on the configuration, and we do not track prices. Generally, features like one-piece construction, elongated shape, or skirted design can affect cost, but you should compare spec sheets and current retail prices without relying on a family name.
