Last Updated on November 8, 2026
This Toto Drake II review compares three elongated two-piece toilets: the standard 1.28 GPF model, a 1.0 GPF version and a 1.28 GPF package with an electric bidet seat. All three have a nominal 12-inch rough-in and a CEFIONTECT-glazed bowl. Their seat, tank and installation requirements are where the buying decision gets more interesting.
With so many toilet brands and models to choose, start by finding a quality flushing toilet that fits your rough-in and leaves enough space in front. The Toto Drake II toilet linked here is the right-hand-lever CST454CEFRG#01. The CST454CEFG in the table has the lever on the left.

Is the Toto Drake II a WASHLET?
The standard Drake II packages below include a tank and bowl. The WASHLET+ S300e bundle adds a powered bidet seat and routes the cord and hose through a matching bowl. The seat still needs a nearby outlet and water connection.
Top 3 Toto Drake II Toilets Comparison Chart
Choose between the standard two-piece model, the lower-flush-volume 1G, and the package that includes the S300e. The plain fixtures are typically simpler purchases because you can choose your own seat.

Toto Drake II CST454CEFG#01 Elongated Toilet Review
The CST454CEFG#01 is the straightforward choice if you want a 1.28 GPF toilet with a separate tank and bowl. The elongated glazed bowl gives you more front-to-back seat room than a round bowl. The elongated profile also needs more door clearance.

Water-saving toilet
The 1.28-gallon Tornado Flush uses 0.32 gallon less per flush than a 1.6 GPF toilet. It’s a single-flush gravity design and carries the EPA WaterSense label.
Installation
The separate tank and bowl are easier to carry in stages. Check whether you need to buy a new flange seal, closet bolts and supply line. The set needs a separately purchased elongated seat.
Easy to maintain
The CEFIONTECT finish reduces how readily residue sticks to the ceramic. It still needs regular cleaning. If you see an older finish name, such as SanaGloss, match the full model number and finish when comparing packages.

Pros and Cons of the Toto Drake II 1.28 GPF Toilet
- Pros. Elongated bowl, Universal Height rim, CEFIONTECT finish and 1.28 GPF WaterSense rating. Separate pieces are easier to carry upstairs.
- Cons. Seat and supply line cost extra, and the elongated bowl requires space in front. The tank-to-bowl joint adds an exterior seam to wipe.
Toto Drake II CST454CUFG#01 1 GPF Two-Piece Toilet
The CST454CUFG#01 trims water use to one gallon per flush. It shares the glazed elongated bowl design with the 1.28 GPF model and uses a tank specified for the 1G flush.

Comfortable sitting height
The Universal Height rim is about the same as the standard Drake II. Compare the finished seat height with what you use now, especially if children or shorter adults will share the toilet.
Appearance and finish
The two-piece model has an elongated front, a chrome lever and a tall tank. Cotton White is the finish shown here. TOTO lists other finishes for the glazed model, so confirm the suffix if matching existing fixtures.
Uses only one gallon per flush
The 1G saves 0.28 gallon per flush compared with the 1.28 GPF model. At 20 flushes a day, that is roughly 2,044 gallons a year. Estimate your own usage with the toilet water usage calculator. TOTO gives extra drain-line guidance for ultra-low-flush installations. Ask a plumber to review the run if your house has a long or trouble-prone drain.

What makes this toilet worth the money?
- Pros. The lowest flush volume of these three fixtures, CEFIONTECT glaze and a chair-height seating option with a suitable seat.
- Cons. The seat is extra. The water savings will matter most in a heavily used bathroom, and the lower-flush-volume model warrants a closer look at the drain layout.
Review of Toto Drake II MW454574CEFG#01 WASHLET+ Toilet
This package pairs a two-piece Drake II with the S300e electric bidet seat. The bowl has a pass-through for the cord and hose. It’s the most complete of the three options if you want a heated seat and bidet functions.

Advanced bidet seat included
The S300e has a heated seat, a remote, and adjustable spray settings. Its SoftClose hinge lowers the seat gently. The separate tank and bowl use the same 1.28 GPF flush volume as the plain Drake II above.

Bowl surface and cleaning
PREMIST wets the bowl before use. The S300e’s EWATER+ function mists the bowl with electrolyzed water, while the CEFIONTECT glaze helps limit sticking. These features supplement normal cleaning.
Warm water and air deodorizer
The seat heats wash water on demand and has warm-air drying and a deodorizer. Plan for an outlet within reach of the seat cord, with space at the back to route the hose.
Pros and Cons of the Toto Drake II WASHLET+ Toilet
- Pros. Heated bidet seat, warm water, remote control, deodorizer and concealed routing in one package.
- Cons. Higher equipment and installation costs, a power requirement and a seat tied to the WASHLET+ bowl connection.
Toto Drake II Installation Tips
Measure from the finished wall to the center of the closet bolts or flange. The three reviewed fixtures use a nominal 12-inch rough-in. An offset flange is only something to consider if a plumber identifies a fit problem. Use a new seal, check that the flange is sound and follow the tank gasket and bolt instructions. The rough-in measuring guide shows where to measure.
On the WASHLET+ version, confirm a GFCI-protected outlet is within reach before installing the bowl. After assembly, check for leaks around the supply connection, the tank-to-bowl joint and the base.

Both fixtures use 1.28 GPF and are sold without a seat. The Cimarron has a slightly wider tank and a different gravity flush system.
An Alternative to the Toto Drake II: TOTO UltraMax II Toilet
The one-piece UltraMax II MS604114CEFG#01 is worth considering if you want an included SoftClose seat and no external tank-to-bowl seam. It uses Tornado Flush at 1.28 GPF, has an elongated glazed vitreous china bowl and a 12-inch rough-in, and carries a one-year limited warranty. The 99 lb shipping weight is for the complete fixture. Plan for a second person to help carry it.
Summary
Pick the 1.28 GPF Drake II for a simpler fixture, the 1G if lower water use is worth checking the drain layout, or the S300e package if you already plan to add an electric bidet. In each case, measure the rough-in and leave room for the elongated bowl.
