Toto Ultramax II Super Quiet Toilet Review in 2026

Last Updated on November 8, 2026

This Toto Ultramax II review compares three versions of the same one-piece idea. If you have been looking through several exceptional flushing toilets, the easiest way to narrow the choice is to decide how much water you want to use per flush and which seat you want in the box. The standard 1.28 GPF model comes with a mechanical SoftClose seat. The 1G uses less water, and the WASHLET+ package adds a powered C200 bidet seat.

Just like the Toto Ultramax, this family has a one-piece tank and bowl. The models covered here have an elongated bowl, a 12-inch rough-in and CEFIONTECT glaze. The suffix matters when matching white fixtures, looking up a replacement part or deciding whether an outlet is needed.

Think about who will use the toilet most and where it will sit. The Toto toilet you pick needs room around it. Check the space in front of the bowl, the clearances around the tank and the finished seat height. A toilet can fit the flange and still leave too little room for the bathroom door.

Toto Ultramax II Toilet Comparison

The first two versions are good starting points if you only need a conventional toilet. Start with the 1.28 GPF model for the familiar flush volume and compare the 1G if water savings are your priority. Plan for the C200 separately if you want a bidet, since the outlet and water connection can affect the cost and layout of the installation.

Toto MS604114CEFG#11 Ultramax II One-Piece Toilet Review

The MS604114CEFG#11 is a 1.28 GPF UltraMax II in Colonial White. Cotton White is the #01 finish, a separate color in the same family. If you are matching a sink or tub, compare actual finish samples or the markings on the fixtures. A product photo on a bright screen can make the two whites look nearly identical.

The molded one-piece body keeps the outside smooth around the tank and bowl. That is helpful for everyday cleaning. It also makes the toilet a single heavy item to carry, so check your route from the door to the flange before removing the old fixture.

Technical Specifications:

Sitting Space

Universal Height gives this model a higher rim than many standard-height toilets. At 17¼ inches with the supplied seat, it may make sitting and standing easier for some adults. Shorter adults and children may prefer a lower seat. Compare the measurement with a chair or toilet they already find comfortable.

The elongated bowl gives extra room at the front of the seat. Check the door swing with a tape measure rather than relying on the rough-in alone. The included SoftClose hinge reduces the noise of the seat and lid closing. Flush sound also depends on the room, supply and drain.

Flushing System

TOTO specifies Tornado Flush for this model. The rim outlets direct water around the bowl while the gravity flush clears the trapway. Older literature uses the name Double Cyclone for this type of bowl rinse. The fixture uses 1.28 gallons per flush and is listed as WaterSense certified.

A clogged drain, a low tank water level or a part that no longer seals can all affect flushing. If you are replacing a toilet because it clogs frequently, identify whether the old toilet or the drain line is at fault. Use the no-clog toilets list for other fixture comparisons.

Cleaning

CEFIONTECT helps reduce what sticks to the glaze. A soft brush or sponge and a suitable mild cleaner are still part of routine care. The one-piece construction eliminates the exterior seam at the tank, but the exposed trapway and floor junction still need wiping.

Pros of the 1.28 GPF Toto Ultramax II Toilet

• Vitreous china body with a smooth tank-to-bowl exterior.
• WaterSense-rated 1.28 GPF flush and CEFIONTECT glaze.
• Elongated SoftClose seat comes with the model.
• Standard 12-inch rough-in and a published one-year limited warranty.

Cons:

• The one-piece body is heavier to handle than a separate tank and bowl.
• Door clearance can be tight in a small room. A higher seat may also be less comfortable for a child or shorter adult.
• Flush and refill sounds depend on the plumbing and room layout.

Toto MS604114CUFG#01 Ultramax II 1G One-Piece Toilet Overview

The MS604114CUFG#01 is the Cotton White 1G version. It keeps the one-piece body and mechanical SoftClose seat, while the rated flush uses one gallon. It is a practical option if several people share the bathroom and you are looking for a way to reduce daily water use.

Technical Specifications:

Flushing Mechanism

The 1G is also a gravity-fed Tornado Flush model. It uses 0.28 gallon less per flush than the 1.28 GPF model. For a household with 20 flushes a day, that difference works out to roughly 2,044 gallons per year. The toilet water usage calculator lets you estimate the difference for your household and rates.

TOTO gives additional drain-line guidance for ultra-low-volume fixtures. If you have an older drain, a long horizontal run or recurring backups, discuss the drainage layout with a plumber before picking the lower-volume model. That can be more useful than judging a fixture solely by the number on the tank.

Who Will Find It Comfortable?

The universal-height elongated bowl has similar fit considerations to the 1.28 GPF model. Check the measured seat height against the fixture you use now and consider who else will use the bathroom. An accessible installation also depends on the lever position and clear space beside the toilet.

Soft-Close Seat

The 1G includes a conventional SoftClose seat. It needs the usual water supply, but the seat has a mechanical hinge and requires no outlet. For a later bidet upgrade, verify seat compatibility and the space between the mounting holes and tank before buying a seat.

Construction

The glazed vitreous china bowl is easy to wipe around the tank. Leave enough access beside the exposed base to clean and to reach the supply shutoff after installation. Keep the model number from the fixture when ordering a tank or valve part.

Pros of the 1 GPF Toto Ultramax II Toilet

• Lowest rated water use of the three fixtures.
• Includes a SoftClose seat and CEFIONTECT bowl finish.
• One-piece exterior and elongated bowl.
• One-year limited warranty.

Cons:

• Check the drain layout if your plumbing has a history of poor carry or repeat blockages.
• A lower rated flush volume alone will not address a drain problem.
• The one-piece fixture still requires a full lift into place.

Toto MW6042044CEFG#01 WASHLET+ Ultramax II One-Piece Toilet Review

The MW6042044CEFG#01 is the 1.28 GPF package with a C200 WASHLET+ bidet seat. The bowl routes the seat’s water supply and cord through a concealed connection. This is the model to compare if you want a heated seat and warm-water wash along with the conventional toilet.

Technical Specifications:

Advanced Heated Seat

The C200 gives you adjustable warm-water spray, a heated seat, warm-air drying and an air deodorizer. The remote controls wash settings. If two people will share the bathroom, check that the remote location is easy for both to reach and that the cord will reach the planned outlet without crossing the floor.

PREMIST Function

PREMIST wets the bowl before use. That rinse and the CEFIONTECT glaze help reduce residue. The wand is designed to clean itself, and the bowl and seat still need regular cleaning with products suitable for their surfaces.

Bowl Height & Shape

The base is a Universal Height elongated bowl. The C200 seat feels different from a simple flat seat because the bidet housing takes up space at the back. If sitting space matters to you, compare the usable opening and finished sitting height with the seat you use now.

Installation

Measure the nominal 12-inch rough-in to the finished wall and check supply valve clearance. The guide to measuring a toilet rough-in shows where to measure when the old toilet is still in place. Plan the GFCI outlet and confirm the required connections with the package instructions before setting the bowl.

Check what the installer needs for the flange seal, mounting hardware and water supply. When the fixture is in place, test the toilet flush first, then check the WASHLET hose connection for leaks and test the bidet controls. Use the installation instructions for the exact toilet and seat combination.

Pros of the Toto Ultramax II WASHLET+ Toilet

• The package includes the heated bidet seat, remote, air dryer and deodorizer.
• Concealed routing gives the hose and cord a more orderly path.
• The one-piece toilet uses a WaterSense-rated 1.28 GPF flush.

Cons: Plan for a suitable outlet, the higher cost of the bundle and the added room taken by the bidet housing.

Comparison Table: Toto Ultramax II vs Aquia IV vs American Standard Cadet 3 Toilet

Compare the type of toilet first, then the exact models. The Aquia IV 1G and round-front Cadet 3 entries describe configurations to look for within those families. Match the tank, bowl and seat package when comparing dimensions or ordering repair parts.

2 Alternatives to the Toto Ultramax II Toilet

Toto Drake II

Look at the Drake II CST454CEFG#01 if you prefer to move the tank and bowl separately. The 1.28 GPF version is a two-piece elongated toilet with a 12-inch rough-in, CEFIONTECT glaze and a seat sold separately. Its Tornado Flush and WaterSense rating make it a useful comparison with the one-piece UltraMax II.

Toto Carlyle II

The Carlyle II MS614114CEFG is a one-piece elongated 1.28 GPF toilet with a skirted base and SoftClose seat. Its 12-inch UniFit configuration and optional compatible adapters make it worth checking if rough-in flexibility matters. Confirm the model and adapter before ordering.

If the issue is a shelf over the tank, the Supreme II and UltraMax II height comparison shows another way to keep a one-piece toilet while reducing tank height.

Troubleshooting Table for TOTO Ultramax II

A flush problem, a refill problem and a floor leak have different starting points. Use the symptom to narrow the cause before changing any tank parts. Several valve revisions exist, so match the replacement to the actual mechanism inside the tank.

Conclusion

Choose the 1.28 GPF UltraMax II if you want a standard SoftClose seat and a straightforward 12-inch installation. Choose the 1G if the water savings are worthwhile and your plumbing suits the lower flush volume. Choose the C200 package if you already want an electric bidet and can plan the outlet. For all three, compare the delivered package, the bathroom clearances and who will use the toilet before deciding.

FAQs

What Is a Toilet Rough-In?

It is the distance from the finished wall to the center of the floor flange or closet bolts. Measure from the wall behind the toilet, leaving out the baseboard. The three models in this Toto Ultramax II review are designed for a 12-inch rough-in.

What’s the Difference Between a One-Piece and a Two-Piece Toilet?

A one-piece toilet combines tank and bowl into a single fixture, with fewer exterior seams to clean. With a two-piece toilet you can carry the bowl and tank separately, and the tank-to-bowl gasket becomes a serviceable part.

How Do I Clean the CEFIONTECT Glaze?

Use a soft brush or nonabrasive sponge and a cleaner suitable for the ceramic finish. Follow the instructions for the bowl and the seat separately. When mineral buildup returns quickly, check whether hard water is the cause.

Do All UltraMax II Toilets Need an Outlet?

The two mechanical SoftClose packages here operate without electricity. The C200 bidet seat in the WASHLET+ package uses a 120 V GFCI-protected outlet.
