Toto People-Centered Design Smart Fact
The Aquia IV Cube toilet uses CEFIONTECT ceramic glaze, which creates an extraordinarily smooth, ion-barrier surface to help keep the bowl cleaner with every flush.

Toilet Technologies


CEFIONTECT is an ultra-smooth ceramic glaze that coats the toilet bowl. Its microscopic surface ridges are far smaller than waste particles, leaving no place for waste to gain a foothold. Extremely durable, CEFIONTECT is designed for enduring beauty and cleanliness.


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. 

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.

Click to learn more about Cefiontect®

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.

Click to learn more about Dynamax Tornado Flush®

With conventional siphon jet flushing systems, the water volume is split between the rim and jet hole, with each responsible for bowl cleaning or waste evacuation. DYNAMAX TORNADO FLUSH® however sends 100% of the water through the rim so all of it is used to clean the bowl and to evacuate waste. This makes it possible to use less water more efficiently.

Drake’s innovative DYNAMAX system generates a vortex that uses a pushing force to send the waste out first, allowing it to travel longer distances than older systems. The combination of the waste discharge and powerful bowl wash using swirling water has dramatically improved the amount flushed away. This new evacuation design also allows for a quieter, more powerful bowl evacuation.

With a modern RIMLESS DESIGN, DYNAMAX uses 360° cleaning power to reach every spot leaving no place for waste or grime to hide, making it easy to clean.

Our Founding Spirit, Alive Today


At TOTO, we’ve always been inspired by a desire to improve everyone’s quality of life. Through almost a century rich with innovation, TOTO has changed the perception of what a bathroom can be — and how it can be used.

Our founder, Kazuchika Okura, had a vision more than one hundred years ago in 1912, before the concept of public sewage systems was widespread in Japan. After seeing more advanced systems overseas, he was moved to establish a ceramic sanitary ware laboratory to develop healthier and cleaner living spaces.

In 1917, Okura founded Toyo Toki K.K. (which became known as TOTO LTD.) to supply the market with these products. TOTO was founded on a commitment to provide a comfortable living space for people, while always protecting the planet and its water.

Japan’s rich artistic heritage in pottery and porcelain is alive in every TOTO product we create today. Throughout our expansion worldwide, TOTO has remained true to the Japanese traditions that have shaped our Company Motto and Philosophy.

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
What kinds of WASHLET are available?


For new toilet installations
Integrated toilet

WASHLET® is a part of the toilet. The toilets were designed with beauty and elegance in mind.
One-Piece/Two-Piece/Wall-Hung Toilet

These are toilets for when you have already decided to attach WASHLET® as they are installed. Just like combination toilets, they portray beauty and elegance.
For attaching to existing toilets
WASHLET® (spray seat)

We have prepared WASHLET® with different designs and various functions. WASHLET® can also be attached to existing toilets.
Can I use WASHLET® in my own home?


Is there access to electricity?

Because WASHLET® uses electricity for its functions and features, it'll need to be plugged into an outlet. Power outlet installation might be necessary if there is none near the toilet.
What is the size and shape of your toilet?

To attach WASHLET® (spray seat) to the toilet you currently use, pay close attention to the size and shape of the toilet as they vary by design. Most likely you'll be able to use WASHLET® (spray seat), but it all depends on the size and shape.
Is there anything near the toilet?

You'll need to make sure there is nothing around the toilet that may obstruct the installation. With WASHLET® (spray seat), your current toilet will become a little bigger. If the room is not wide enough, or if there is anything around the toilet that could get in the way, it may not be possible to attach the WASHLET®. As a guide, there should be at least about 30 cm to the left and right of your current toilet.
Is your toilet located in a place where it is subjected to water on a daily basis?

Attaching WASHLET® to a toilet that is subjected to excessive amounts of water from the shower, or using water to clean the entire toilet, may result in failure of WASHLET®.
I don't own a TOTO toilet, can I still install TOTO WASHLET on non-TOTO toilet bowl?


Subjected to the toilet's shape and size, as well as the distance between the seat and cover bolt holes. You will be required to remove your existing toilet seat to get the accurate measurements of the distance between the bolt holes, and also the distance from the bolts holes to the front of your toilet’s tank. TOTO Universal Base Plate ( sold separately ) can be used to adjust the distance of the bolt holes to get the best fit.

What should I do if I smell an odor in my Washlet?


If an odor is present, please remove the main unit and clean the deodorizer screen.

Here's what to do:

  • Remove the deodorizer filter.

    Unplug the power cord
    Remove the main unit. With the release button on the right side of the unit pressed in, pull the main unit forward.
    Make sure not to pull with excessive force because of the water supply hose and power cord.
    Tilt the unit up so you can reach the underside. Then press the clip of the filter and pull it forward.

  • Clean the filter using a toothbrush or similar implement ot remove dust or lint.
  • Attach the deodorizer filter.

    Hook the left side of the filter onto the main unit and slide the filter securely until you hear the clip “Click”.
    Never use the Washlet without a filter. (It could cause a malfunction)

  • Attach the main unit.

    Align the center of the main unit and the base plate. Slide the main unit along the surface of the toilet and press all the way into place until a “click” is heard. Please note that if the main unit is not securely on the base plate, the washlet will not function.

  • Plug in the power cord
Where do I find the model number and serial number of my Washlet?


The product identification label is attached at the rear of the main unit of your WASHLET. So you will not be able to read it until you slide the washlet forward away from the toilet tank. Here’s what to do:

  • Locate the quick release button on the side of WASHLET.
  • While pushing the quick release button, pull WASHLET forward.
  • Label will be on the rear.

The Model Number is in the upper left. The Serial number will be toward the bottom left. See the example below.
