Toto Eco Ultramax ADA Compliant Toilet: Review and Buying Guide

Last Updated on November 8, 2026

If you’re shopping for durable one-piece toilets, the TOTO Eco UltraMax is a useful place to start. It combines the tank and bowl into one piece and uses a 1.28 GPF gravity flush. The choice gets more specific when you decide between a round bowl, a standard-height elongated bowl and the taller ADA-height elongated version.

The smooth exterior and included SoftClose seat cover some of the features homeowners desire in a modern toilet. Before comparing packages, measure your bathroom and write down the whole model number. One letter can change the seat height or the glaze.

Toto Eco Ultramax MS853113E Toilet Review in 2026

The MS853113E is the round-front Eco UltraMax. It is a high-efficiency toilet with a low standard-height rim and a round SoftClose seat. Choose it when a short bowl projection matters, such as when a bathroom door swings close to the front of the toilet.

The MS854114E keeps the standard-height rim and adds an elongated bowl. The MS854114EL or MS854114ELG gives you an elongated bowl with a higher rim. The link in the table goes to the standard-height MS854114E#01. Use the model number in the first row to tell the three configurations apart.

Technical Specifications:

The model’s shipping weight includes the packaging. For installation, plan for two people to lift the one-piece toilet if the stairs, doorway or flange are difficult to reach. Use the toilet fit checker to see how the bowl, tank and door clearances work together.

Pros: Why Should You Buy a Toto Eco UltraMax Toilet?

• All three versions use 1.28 gallons per flush and have a one-piece vitreous china exterior.
• A round-front model gives you a shorter bowl. The elongated models offer more sitting space at the front.
• The matching SoftClose seat comes with each configuration covered here.
• A CEFIONTECT version is an option if you want a glazed elongated bowl.
• The taller EL series gives you a separate choice when the standard rim sits lower than you prefer.

What Are the Drawbacks of the Toto Eco UltraMax?

• The tank and bowl have to be moved together, which can make a one-piece fixture awkward to lower onto a flange.
• The ADA-height seat can feel high for children and shorter adults. If a low tank is the issue, see the Toto Carolina ii low-profile toilet for comparison. Tank height and seat height are separate measurements.
• A CEFIONTECT label depends on the suffix. Check the exact model if the glaze is part of your buying decision.

Is the Toilet Durably Made?

To choose the most durable toilet for your bathroom, look at the fixture and the service parts separately. The Eco UltraMax tank and bowl are molded from vitreous china. The fill valve and the flush seal still wear with use. Keep the tank marking so you can match parts if the toilet starts running after a few years.

The E-Max design uses a wide flush valve to release water into the bowl. Flush performance also depends on the water level, a clear trapway and a drain that can carry the waste away. If the old toilet backs up regularly, solve that problem before assuming a different fixture will clear the line.

Space-Saving One-Piece Design

One of the practical differences between two-piece and one-piece toilets is that the one-piece unit has no exterior joint between tank and bowl to wipe around. The round-front MS853113E is the shorter choice in this family. The elongated model adds room at the front of the seat, so measure the aisle and door swing before selecting it.

The 12-inch rough-in is the nominal distance from the finished wall to the center of the floor bolts or flange. A 12-inch rough-in tells you where the toilet connects. The depth drawing tells you where the front of the bowl will end up.

What Is Different About the ADA-Height Elongated Model?

The ADA-height MS854114EL and MS854114ELG have a higher rim than the MS854114E. The drawing for the tall version gives an installed seat height of about 17¹¹⁄₁₆ inches with its matching seat. For a fully accessible installation, check the lever approach side, floor clearances and seat height in the final layout.

For a household bathroom, the choice can be simpler. Measure the height of a seat everyone already uses comfortably and compare it with the model you want. The comfort-height and standard-height comparison explains where the extra height can help.

SanaGloss and CEFIONTECT Bowl Finishes

TOTO has used SanaGloss in older literature and CEFIONTECT in newer literature. In this family, the MS854114EG and MS854114ELG are examples with the special bowl glaze. The MS854114E and MS853113E are sold with the standard glaze.

The coating helps reduce sticking, but the bowl still needs normal cleaning. Use a nonabrasive brush or sponge and the manufacturer’s care instructions. Clean the seat with a product suitable for the seat material. If hard-water deposits keep coming back, the glaze alone will not solve the water problem.

How E-Max Compares With G-Max

The Eco UltraMax uses a 1.28 GPF E-Max flush. Earlier standard UltraMax configurations used a 1.6 GPF G-Max system, and Toto Drake 2-piece toilets include several other flush systems and volumes. Compare the full model numbers when deciding how much water you can save.

At the same number of flushes, a 1.28 GPF fixture uses 20% less water than a 1.6 GPF fixture. Actual refill time depends on the supply and fill valve setting. Wait for the tank to finish refilling before judging the next flush.

Is Eco Ultramax EPA WaterSense Certified?

The Eco UltraMax configurations in the specifications table carry the WaterSense designation. If your water utility offers a rebate, check its approved list for the exact model before counting the rebate in your budget.

Is a Soft-Close Seat Included?

Yes. TOTO specifies the round SoftClose SS113 for the MS853113E and the elongated SS114 for the MS854114E and ADA-height configurations. That differs from the plain Toto Drake II toilets, which typically take a separately purchased seat. Measure the bowl shape and mounting spacing before buying a replacement.

Does It Offer a Warranty?

TOTO specifies a one-year limited warranty for the Eco UltraMax. Keep the receipt and the exact model code. The Toto Ultramax and Toto Ultramax II families have their own specifications and replacement parts, even when the fixtures look alike.

Compare With Other Toilets: Toto Eco UltraMax vs UltraMax II vs Drake vs Drake II

The comparison uses a specific configuration from each family. The CST746CSMFG sometimes listed alongside these models is a separate Drake with a 1.6/0.8 GPF dual flush. The Drake II in this table is the CST454CEFG, a 1.28 GPF single-flush model.

Bottom Line

Choose the round MS853113E if projection is tight. Choose the MS854114E if you want an elongated bowl at standard height. Choose the EL series if a higher seat suits the people who will use it. All three use 1.28 GPF, so the main buying differences are shape, sitting height and the optional glaze.

FAQs

What Cleaner Can I Use on CEFIONTECT or SanaGloss?

Use a soft brush or nonabrasive sponge with a cleaner suitable for the bowl finish. Avoid abrasive scouring pads, and follow the seat’s separate care instructions.

Can I Install the Eco UltraMax Myself?

If the shutoff, flange and rough-in are already suitable, the basic connection is similar to other floor-mounted toilets. The one-piece body is the harder part to handle. Have help lifting it and use a plumber if the flange is damaged, the shutoff will not close or the toilet leaks at the base after installation.

How Can I Tell a Standard Eco UltraMax From the ADA Version?

Read the model number on the fixture or its paperwork. The MS854114E is standard height. The L in MS854114EL or MS854114ELG identifies the taller version. The G identifies the optional glaze on the variants discussed here.
