Toto Ultramax II

The TOTO UltraMax II is a one-piece elongated toilet with TORNADO FLUSH, CEFIONTECT glaze and Universal Height, sold here on its own or as a complete WASHLET+ set with the S7 or S7A bidet seat. Both flush volumes are stocked: 1.28 GPF and the 1G version at 1.0 GPF.

What Makes the UltraMax II Different From the Original UltraMax

The UltraMax II differs from the original UltraMax in four ways: the flush system, the glaze, the seat height, and how much water it uses. The original runs TOTO's G-Max flushing system at 1.6 GPF. The UltraMax II runs TORNADO FLUSH at 1.28 GPF — or 1.0 GPF on the 1G models — adds CEFIONTECT glaze, comes in Universal Height, and is built to take a WASHLET+ seat. If the older version is what you are after, the UltraMax collection still carries the standard and Eco models.

The flush system is the biggest change

TORNADO FLUSH uses two nozzles that create a centrifugal, cyclonic rinsing action, which reduces waste buildup and keeps the bowl cleaner, and it comes with a hole-free rim that TOTO says performs more consistently and is easy to clean. G-Max, on the original UltraMax, draws water into the bowl more quickly and out more forcefully. It works, but it is the older design and it needs 1.6 gallons to do the job.

CEFIONTECT is on the II, not the original

CEFIONTECT is an extraordinarily smooth glaze that prevents particulates from adhering to porous ceramic surfaces, using an ion barrier to keep the surface clean over time. Paired with the computer-designed, fully glazed trapway that both models share, it is the reason the UltraMax II bowl needs less scrubbing and less cleaning product to keep it looking new.

Universal Height comes standard

Every UltraMax II is Universal Height and ADA compliant. In practice that puts the seat about two inches higher than a standard-height bowl — closer to a dining chair than a low stool — which most adults prefer and which makes standing up easier for anyone with knee, hip or back trouble. Our comparison of Universal Height and standard height explains how to tell the two apart from the model number.

Where the UltraMax II Will Not Fit

The limits are short and worth knowing before you order:

  • 12-inch rough-in only. TOTO offers no 10-inch or 14-inch version of this series and no Unifit adapter for it. Measure from the finished wall to the center of the closet bolts first — the rough-in size guide walks through it.
  • Elongated bowl only. There is no round UltraMax II. An elongated bowl runs about 18.5 inches from the seat bolts to the front rim, against roughly 16.5 inches for a round one.
  • One-piece means one piece. It arrives as a single heavy unit, and the tank lid is specific to the model rather than a generic replacement part.
  • The WASHLET+ sets need an outlet. A grounded outlet within reach of the toilet is a requirement, not an option, on any electric seat.

UltraMax II or Drake: Which TOTO Should You Buy?

Buy the UltraMax II if you want a one-piece toilet and your rough-in measures 12 inches. Buy the Drake if you need a two-piece, a 10-inch rough-in, or a fixture you can carry in two manageable pieces. Both run TOTO flush engineering and both are stocked here, so this is a decision about format and fit, not about which one is the better toilet.

The UltraMax II fuses tank and bowl into one unit. That means fewer joints, no gap between tank and bowl to clean around, and no tank-to-bowl gasket in the picture — but also one heavy ceramic piece to move and a tank lid particular to the model. The TOTO Drake arrives as a separate tank and bowl, which is easier to handle and install, and it is the series to check if your measurement comes back at 10 inches, because TOTO sells that as a separate toilet rather than an adapter. If you need 14 inches, neither one helps: look at TOTO's Unifit series, such as the Legato, where the alternative rough-in is an adapter sold separately.

Choosing Between the WASHLET+ S7 and S7A

The difference between the S7 and the S7A on an UltraMax II is the lid: the S7A opens and closes automatically, and the S7 does not. TOTO's own feature comparison for these sets lists everything else identically on both seats — EWATER+, PREMIST, a deodorizer, an air dryer, a heated seat, rear and soft rear cleanse, front cleanse, wide front cleanse, and a night light. So the question is simply whether a lid that moves on its own is worth the difference to you. Compare the two ranges side by side: toilets with the WASHLET S7A or toilets with the WASHLET S7.

Both are WASHLET+ sets, which TOTO describes as a system that neatly conceals the WASHLET power cord and water supply hose for a clean installation. The seat and bowl are sold matched, so there is no compatibility check to do and no cord crossing the floor to an outlet. On the wash side, EWATER+ electrolyzes water to produce a sterilizing agent, hypochlorous acid, that is used to keep the wand and toilet bowl hygienic, and PREMIST wets the surface of the bowl before use, aiding in the removal of waste.

1.28 GPF or the 1G at 1.0 GPF

Both flush volumes carry the same TORNADO FLUSH, the same CEFIONTECT glaze, the same elongated bowl and the same Universal Height, and both are WaterSense certified — the 1G simply uses a gallon per flush instead of 1.28. Very low volumes leave less margin in older plumbing, so if your drain run is long or shallow, the 1.28 is the safer choice. Our guide to TOTO flush volumes covers where each one is required and where it is not.

Color

TOTO lists the toilet on its own in Cotton, Colonial White, Sedona Beige, Bone and Ebony. The WASHLET+ sets are listed in Cotton. Check the individual listing here for the finish it actually ships in.

Frequently Asked Questions about Toto Ultramax II

Is the TOTO UltraMax II worth it?

The TOTO UltraMax II is worth it if you want a one-piece toilet that stays clean with little effort and the option of a matched bidet seat. What you are paying for is TORNADO FLUSH, CEFIONTECT glaze, a fully glazed computer-designed trapway, Universal Height and WaterSense certification in a single fixture. If none of those matter to you, a simpler two-piece TOTO does the same basic job for less.

Does the TOTO UltraMax II have Tornado flush?

Yes, the TOTO UltraMax II has TORNADO FLUSH, and TOTO lists it on every UltraMax II model including the 1G. Two nozzles create a centrifugal, cyclonic rinsing action that reduces waste buildup and keeps the bowl cleaner, and the rim has no holes for residue to collect in. The original UltraMax does not have it — that model uses the older G-Max system.

Does the TOTO UltraMax II flush as well as an older 1.6 GPF toilet?

The TOTO UltraMax II flushes as well as an older 1.6 GPF toilet while using 1.28 gallons, because TORNADO FLUSH was engineered around the lower volume rather than throttled down to it. Every UltraMax II is WaterSense certified, meets the 1.28-gallon ceiling states such as California and Texas set for new installations, and is often rebate eligible.

What rough-in does the TOTO UltraMax II need?

The TOTO UltraMax II needs a 12-inch rough-in, and TOTO offers no 10-inch or 14-inch alternative for this series and no Unifit adapter. Measure from the finished wall behind the tank to the center of the closet bolts before ordering, not from the baseboard. If you measure 10 inches, look at the Drake instead, where the 10-inch is sold as a separate toilet.

Will an elongated UltraMax II fit a small bathroom?

An elongated UltraMax II fits a small bathroom only if you have the depth for it, because TOTO lists no round version of this series. Allow about two inches more depth than a round bowl and around 21 inches of clear space in front of it, as our elongated versus round guide advises. If a door or vanity would clash, shop round toilets instead.

Is a seat included with the TOTO UltraMax II?

Yes, a seat is included with the TOTO UltraMax II. The toilet on its own ships with TOTO's SoftClose SS124 elongated seat and a chrome trip lever. The WASHLET+ versions come with the S7 or S7A bidet seat already matched to the bowl, with the power cord and supply hose concealed, so there is no separate seat to buy or fit either way.

Does the UltraMax II WASHLET+ have auto flush?

Auto flush is not a feature of the UltraMax II WASHLET+ sets sold here — none of the S7 or S7A sets in this collection are the auto-flush configuration, so you flush with the trip lever or the remote. If hands-free flushing is what you want, the models that have it are TOTO's NEOREST and G5A ranges: see auto flush bidets and toilets.

How long does a TOTO UltraMax II WASHLET+ set last?

A TOTO UltraMax II WASHLET+ set lasts as long as its two halves do. Our one-piece and two-piece comparison puts a toilet at 15 to 25 years with proper maintenance, and the smart toilet guide puts the electronics at 10 to 15 years or more. The tank parts are still replaceable on a one-piece, but the UltraMax II tank lid is specific to the model.

What is the best price for a TOTO UltraMax II toilet?

The best price for a TOTO UltraMax II depends on the configuration, not on hunting for a discount. The toilet on its own is the least expensive way in, a WASHLET+ S7 set costs more, and the S7A set with the auto open-close lid sits at the top. Prices move, so compare the live listings here against our bidet toilets $1,000 to $2,000 tier.
