If you’re comparing the Toto Drake II vs. UltraMax II to pick the right toilet for your needs, start with how the toilet is built. The Drake II is a two-piece unit, so you can carry the tank and bowl separately. The UltraMax II is a one-piece unit, so there’s no exterior tank-to-bowl seam to wipe. The two models compared below are both rated at 1.28 gallons per flush.
If you want a different handle side, the right-hand-lever Drake II CST454CEFRG#01 is a separate option. Buy Toto Drake ii.
For a bidet upgrade, the UltraMax II CST604CEFGAT40#01 is a WASHLET+–ready fixture. Allow for a compatible seat or bidet package when comparing its total cost. Buy Toto Ultramax ii.

More Details on the Toto Drake II and UltraMax II
Both Toto toilets are sturdily made with elongated bowls and a glazed surface. The choice mostly comes down to the seat package, the tank seam and whether you want to handle the toilet in one or two pieces.
Toto Drake II Two-Piece Toilet
The Toto Drake II toilet is elegantly built as a separate tank and bowl. With the CST454CEFG#01, you get a chrome left-hand lever, a 12-inch rough-in and a glazed bowl. The seat is a separate purchase, so you can choose the height and hinge style that suit your bathroom.
The gravity-powered Tornado Flush swirls water around the bowl. Its 1.28 GPF rating matches the UltraMax II configuration in the table. If you are replacing a different-generation Drake, use the Toto Drake VS Drake II Toilets Comparison to sort out the model differences.
CEFIONTECT, called SanaGloss in older literature, is the finish on the compared configuration. The Toto Eco Drake Toilet Review covers a separate two-piece model.
Pros
- Separate pieces are easier to move through a tight stairwell or doorway.
- The 1.28 GPF model is WaterSense-certified.
- The elongated bowl leaves more room front to back, and you can choose the seat.
Cons
- The seat and supply line are separate purchases.
- The external tank joint takes a little more cleaning and adds a gasket to service.
Toto UltraMax II One-Piece Toilet
The Toto Ultramax ii toilet comes with the tank and bowl formed together. The MS604114CEFG package includes a SoftClose seat. Its elongated CEFIONTECT bowl and 1.28 GPF Tornado Flush are similar to the Drake II’s for everyday use.
TOTO lists Cotton, Colonial White, Bone and Sedona Beige for the glazed version. The Ebony MS604114CEF omits that glaze. For earlier designs, see Toto Ultramax II VS Ultramax: Which is Better? and the Toto Eco Ultramax Toilet Review.
Pros
- A continuous exterior around the tank and bowl makes wiping easier.
- This model includes an elongated SoftClose seat.
- The 1.28 GPF flush is WaterSense-certified.
Cons
- The one-piece fixture is heavier to lift into position.
- The included seat adds value only if it is the seat you want. Compare the price with your preferred Drake II seat included.
In-Depth Comparison
Flushing System
TOTO lists Tornado Flush for both. Each model in the chart uses 1.28 GPF, and both groups score 800 g in MaP’s bulk-removal test. Choose between them on fit, handling and maintenance. The one-piece body by itself does not change the rated flush volume.
One-Piece vs. Two-Piece Design
You can lift and replace a Drake II tank separately. The UltraMax II has no separate tank gasket, but you still need to identify the correct fill and flush parts from the model marking before ordering repairs.
Size Comparison
The Drake II projects about ⅜ inch farther and is about 11⁄16 inch taller at the tank. Both use a 12-inch rough-in. The UltraMax II tank is slightly wider, so measure side clearance as well as depth. Enter your measurements in the bathroom toilet fit checker if a door or cabinet is close.
Installation Process
Both mount to a floor flange. For the Drake II, set the bowl and then assemble the tank with its specified gasket. For the UltraMax II, move the fixture in one piece and get help lifting it. Check the supply valve position against the model drawing.
Price Difference
Compare delivered prices with a seat, supply line and seal included in your budget. An UltraMax II WASHLET+–ready fixture is a different package from the standard SoftClose model.
Which Is Better? Toto Drake II or UltraMax II?
Choose the Drake II if you want to carry the fixture in two pieces or select your own seat. Choose the UltraMax II if you want an included seat and a simpler exterior to clean. TOTO makes several toilet models, with Toto Drake and Toto Ultramax toilets being some of the most popular, so match the model number before using any of these specs for a different generation.
FAQs
Which toilet uses less water?
The two models in this Toto Drake II vs. UltraMax II comparison use 1.28 gallons per flush. TOTO also lists separate 1.0 GPF versions, CST454CUFG and MS604114CUFG, for buyers comparing lower water use.
Does each toilet come with a SoftClose seat?
The UltraMax II MS604114CEFG includes one. The standard Drake II CST454CEFG does not include a seat. Use the toilet seat size guide if you’re checking a seat you already own.
Are both configurations suitable for an accessible installation?
TOTO lists both for accessible installations when installed as specified. Check the height with the actual seat, the approach side of the lever and the clearance around the bowl.
Can the two toilets use the same repair parts?
Identify the tank and bowl model first. Some TOTO parts fit more than one model, but the Drake II tank-to-bowl hardware is specific to its two-piece construction.
