 Toto People-Centered Design Smart Fact

The Aimes One Piece HET uses CEFIONTECT ceramic glaze, which creates an extraordinarily smooth, ion-barrier surface to help keep the bowl cleaner with every flush.

Technology & Innovation Highlights



TOTO’s extraordinarily smooth CEFIONTECT glaze prevents particulates from adhering to porous, ceramic surfaces. The ion-barrier in CEFIONTECT keeps everything cleaner, longer. Less cleaning means fewer chemicals in the environment and less water used for cleaning.



Eliminating the microscopic gaps where waste hides

Conventional ceramic may appear perfectly smooth to the eyes, but has gaps where waste particles hide. At just one millionth of a millimeter, CEFIONTECT’s surface ridges are much tinier than waste particles.


What makes CEFIONTECT so durable?

Glass layers are burned onto conventional glaze, making CEFIONTECT an extremely durable material.


Water Hydrophobic

Water Hydrophilic



Water has a strong affinity to CEFIONTECT

The term hydrophilic describes matter that is attracted to water. Due to the hydrophilic nature of CEFIONTECT, water spreads easily over the toilet bowl, effortlessly washing waste particles away.

Tornado Flush


The TORNADO FLUSH features two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup and keeps the bowl cleaner. Using only 1.28 gallons per flush, this high-efficiency system is more effective in one flush than most toilets are with multiple flushes. The modern hole-free rim design means that it performs more consistently and is easy to clean.

  • Dual-nozzle water propulsion system
  • More powerful flush
  • 1 gallon or 1.28 gallon per flush
  • Cleaner bowl and less cleaning



Dynamax Tornado Flush®
uses 100% of water to clean and rinse bowl.

Dynamax combines powerful bowl
cleaning and waste evacuation using
water that is 100% projected from the
rim creating 360° cleaning power. Using
only 1.0/0.8 or 1.28/0.8 gallons per flush, coupled with a 25% larger trapway diameter, this high-efficiency system uses 20% less water with improved performance while also creating a quieter flush. With a modern rimless design, it performs more consistently and is easy to clean.


Powerful washing where waste accumulates most easily

Tornado Flush’s dynamic waterjet discharges from near the front of the toilet bowl, travels in a narrow channel along a hairpin curve, and with sustained water pressure thoroughly cleanses the areas where waste accumulates most easily - and then washes the entire bowl clean. Exquisitely high-quality ceramic makes this innovative design possible.


The Rimless design not only leaves no place for waste and germs to hide. It also makes for a much easier to clean toilet.

Skirted Design



The skirted design, available in many modern TOTO toilet collections, offers clean lines, minimal flourishes and geometric precision. This style is elegant and smooth, concealing the trapway, and features a base that is easy to clean and maintain.

Frequently Asked Questions

What’s the best way to clean my Cefiontect product?
For regular cleaning of your CEFIONTECT product:

  • Use a detergent or non-abrasive toilet cleaner.
  • Use a soft-bristled plastic brush to clean your CEFIONTECT toilet.

  • Use cleansers, polishing powders or detergents that include gritty or coarse particles which might scratch the china surface.
  • Use acid or alkaline detergents or cleaners which could etch the china surface.
  • Use metal scrub brushes or steel wool to clean your CEFIONTECT products.
  • If you have hard water stains, see How to remove hard water stains from your CEFIONTECT product
How can I determine why my toilet isn’t flushing properly?
  • Clogged sewer line or toilet bowl clogs
  • Clogged vent line
  • Incorrect settings or worn out toilet parts
1. Clogged sewer line or clogged toilet bowl

Symptoms: When flushing, the toilet’s water level would rise in the bowl and slowly drain. This is a telltale sign that your toilet is clogged

Solution: Try plunging your toilet or using a closet auger to see if the stoppage can be dislodged. If you are unable to remove the blockage, you may need to contact a local plumber for assistance.

2. Clogged vent line

Symptoms: You notice that your toilet gurgles or that bubbles blow out during the flush, or you just get a weak flush that may leave materials behind in the bowl.

Every appliance that drains into the sewer line has a vertical vent line that allows air to enter the pipe. (These are the pipes that are sticking up thru your roof) The vent must be open to allow air to come in behind the water and waste as they flow through the pipes. Without the air coming in through the vent, a vacuum is created by the water flow. The vacuum slows down the flow of the waste, which can cause solids to settle out and cause a line clog. There are many reasons why a vent pipe would get clogged, including:

  • A previously clogged sewer pipe may have allowed solids to back up into the air vents. When the clog was cleared, materials stayed lodged in the vent pipe.
  • A snow and ice storm may have allowed an ice cap to form, closing off the pipe.
  • A squirrel or bird may have decided the pipe was a good place to build a nest, or store food.
There is a simple test that you can run to verify you have a clogged vent pipe. Take a large bucket of water and pour it quickly into the toilet bowl. If the vent pipe is clear, the water will go down the drain as fast as you can pour it. If the vent is clogged, the water level in the bowl will rise as the vacuum forms. Stop pouring if the water level rises, as we don’t want to overflow the bowl. Solutions: Whatever is obstructing the vent pipe needs to be removed. The easiest way to do this is to take a garden hose up onto the roof, and run water down into the vent pipe. This water will force the obstruction down into the sewer pipe, clearing the vent. Because of the risk of fall, you may want to hire a professional to do this.

3. Incorrect settings or worn out toilet parts

Symptoms: When you flush your toilet, the flush seems very weak or it flushes well every other flush.

Solutions: Incorrect Settings: The water level in the tank should be about ½ inch below the top of the overflow tube. The chain on the flapper should only have 1 or 2 links of slack and the black refill tube from the fill valve, should be flowing water into the overflow tube during the refill.

Worn out parts: A worn out flapper, fill valve, trip lever or flush valve may be causing the flushing problem. See our FAQ titled: HOW TO DETERMINE IF YOU NEED TOILET REPLACEMENT PARTS.
How do I know if I need replacement parts for my toilet?

Most toilets have only 4 components that may need to be replaced if the toilet doesn’t shut off.

  • The flapper
  • The flush valve
  • The fill valve
  • The trip lever
The first step is to determine where the leak is occurring. There is a simple "no tools needed" test to determine which part is causing the problem.

1. Allow the tank to fill, then close the water supply at the shutoff valve. Mark the water level inside the tank, and let sit overnight. If the water level drops, it is either a problem with the flapper or with the flush valve.

2. To determine if it is the flapper or the flush valve, hold the handle down so the water level in the tank goes out to the level where the flapper and the flush valve meet. Let it sit overnight.
  • If the water level does not drop, the problem is with the flapper. See our FAQ titled: How to replace a rubber flapper.
  • If the water level drops to the bottom of the flush valve, where it meets the china, the gasket at the base of the flush valve is bad. See our FAQ titled: How to replace a flush valve on a two piece toilet.
3. If the water in Step 1 did not drop at all, the problem is most likely with the fill valve. Other symptoms that help confirm the problem is with the fill valve include: Water is going over the top of the overflow tube on the flush valve.
  • It might be hissing or continually dripping from the end of refill tube into the overflow tube on the flush valve.
  • If the water is not filling the tank at all, or is filling in erratic starts and stops, it is possible you have debris in the valve. For this symptom, cleaning the fill valve may eliminate the symptom.

4. Erratic flushing may also occur if the trip lever is wearing out. Replacement should solve the problem. See our FAQ titled: How to replace a trip lever.

What’s the safest way to remove hard water stains from my Cefiontect product?
The tips below are for any TOTO china product (including CEFIONTECT):

Hard water marks are composed of minerals from the water supply. They will not dissolve using bleach or detergents. It takes a slightly acidic cleaner like vinegar or a lime dissolving cleaner to remove the minerals. Neither of these cleaners will harm the CEFIONTECT finish.

You can use vinegar or lime dissolving cleaner and a non-scratch scour pad made for porcelain. Allow a little contact time to allow the cleaner to dissolve the buildup.

If the stain at the waterline in your toilet bowl persists, you may need to remove some water from the bowl. Then reapply the vinegar or lime dissolving cleaner at full strength. Removing the water prevents the solution from being diluted.
How should the balance spool in a shower valve TSPTR/TSPVR be serviced?

Removing the Balance Spool:

  • Turn both water stops (hot and cold) clockwise to shut off the water to the valve.
  • On the valve, the balance spool is located next to the cold-water stop and looks like a hex nut.
  • With a wrench turn the hex nut counter clockwise and pull the balance spool out.
  • The balance spool consists of the large cylinder with a smaller cylinder inside. The inner cylinder should move freely inside the large cylinder.

Cleaning the Balance Spool:

  • If the inner smaller cylinder is stuck, shake or tap the spool to release inner cylinder. Rinsing the spool with warm water will help loosen the cylinder.
  • Clean both the inner and the outer cylinders with warm water, vinegar, or household cleaner and rinse.
  • Reinsert the inner spool (cylinder) into the large spool and verify that the inner spool moves freely.

Installing the Balance Spool:

  • Verify that the balance spool has an O-Ring next to the lip of the hex nut.
  • Verify that the inner spool moves freely inside the large spool.
  • Insert the balance spool (both cylinders) and turn clockwise with wrench and tighten.
  • Check for leaks when the water stops are turned on.
What is toilet mold, and how do I get rid of it?

Mold: How it may have gotten there, and how to remove it.

What is Slime Mold?

Slime mold is a special class of mold that forms a slime coat to protect it from harsh environments. A toilet bowl provides the perfect atmosphere for any type of microorganism as it has food, water, air and a nice warm location.

Mold can come in a variety of colors – most are black or dark brown, but they also show up in pinks, blues, reds and some of them are absolutely beautiful. Don't let the pretty colors fool you, if you don't remove them they will take over the toilet.

How Did Slime Mold Get in my Toilet?

Mold spores are everywhere, and can travel through the air. (Ever wonder how the mold got on that slice of bread?) When one hits the toilet bowl, it may start a small colony, and if left alone, will completely cover the inside of the bowl. It can also grow in the tank if that is where the spore landed. It is not uncommon for the mold to show up in all the toilets in a single home, especially when the homeowner uses one toilet brush to clean all the toilets.

When we explain this to customers, their first reaction is "No way! I am a meticulous housekeeper." This is not an indication of poor house keeping. The spore may get picked up on your clothes during your daily travels, and fall into the bowl when you use the toilet at home. It is also possible for the spores to have come in on the tools that were used to install the new toilet.

How do I Eliminate Slime Mold?

Chlorine will kill the mold spore, but if it has already developed a slime layer, chlorine alone won't work. In order to remove the spots, you need to:

  • Scrub the colony off the china, using a non-scratching scour pad.
  • Then you need to follow up with a chlorine rinse to kill the spores that you removed, or they will just form another colony.

It may take repeated treatments to finally kill off the colony. One way to ensure continuous treatement is by using an in tank Chlorine tablet. Our installation manual warns against the use of these in tank tablets, but we need to address the mold issue, and we are only going to use it once. The tablet will last about 30 days, and each time the toilet is flushed, it will wash all the water contact surfaces with a little extra chlorine. This step is essential if the mold has grown up in the rim holes, as you will be unable to scrub that area.

Where do I find the model number and color code for my toilet?

To find the toilet model number and color code:

Watch this short video or follow the instructions below.

  • Look inside your tank or under your tank lid. Always exercise caution when removing the tank lid, as it is a fragile item.
  • On the china walls inside your tank you will see a model number stamped or engraved in the porcelain. They will have letters with a three-digit number. There may be more letters following, depending on additional features available on that model of the toilet. This stamp maybe on your tank lid as well.

    For Example:

    CST 854

  • The most common location for these markings is on the back wall of the tank, or on the right hand wall, opposite the trip lever.
  • The color code will start with a # followed by a two-digit number.

    For Example:

    #01 - Cotton White
    #03 - Bone
    #04 - Grey
    #11 - Colonial White
    #12 - Sedona Beige
    #51 - Ebony
