The TOTO Washlet G400 is an incredible unit that gives you total self-cleaning effortlessly. It features TOTO’s 3D Tornado Flush system that gets rid of all the waste in the bowl nearly every time. Additionally, it’s other features and technology combine to create an ultra-modern, eye-catching, and luxurious toilet.

Most importantly, it allows you to select the pressure of the flush system with a single touch. It features two different flush levels: 1.28 or 0.9 gallons per flush. These levels can be selected appropriately for the business that you have just done. Also, this model has many other features that make it one of the most innovative toilets.

Let’s have a look at the review.

Design

This washlet has a universal seat, ideal for elders or people with disabilities. Additionally, it features TOTO’s CEFIONTECT ceramic glaze for a super smooth and shiny look. It also protects the surface of the toilet from bacteria, to cut the need for regular cleaning.

The skirted design of G400 is easy to clean from the outside. It saves a lot of space in the bathroom and doesn’t have any corners and contours like two-piece toilets. Also, this toilet features an auto-open and close lid that you command via remote control. It also comes with a heated seat feature. It is settable to the temperature between 82°F and 97°F. It contains an integrated sensor that heats the toilet seat for optimal comfort.

Flushing System

Another fantastic feature of the TOTO Washlet is its 3D Tornado Flush system. This unit uses two different flushing levels: 1.28 and 0.9 gallons per flush. You can choose between the levels depending on what you need to flush down. The low water usage makes this toilet EPA WaterSense certified. Additionally, it has an automatic flush operation that works as soon as you leave the toilet seat. The TOTO Washlet also comes with an auto flush Premist™ feature that wets the bowl before each use.

One of its significant features is the remote control operated washing. Also, this unit uses water with adjustable temperature and pressure control.

Cleaning

Cleaning this toilet requires minimal effort. That is because it has a CEFIONTECT glaze finish that keeps the surface clean. It also prevents the growth of bacteria and microbes on the surface. In addition to that, it minimizes the debris and mold from sticking to its surface. It helps in keeping your toilet clean for a long time.

Another fantastic feature is its deodorizer, which helps with the prevention of odor-formation. This deodorizer effectively cleans the air around the unit using powerful air filters. The air around the toilet draws towards the filters. When it passes through an ionized filter, it eliminates the smell. Hence, a cleaner and odor-free bathroom. In addition to that, a built-in dryer dries the seat after each use. This temperature-adjustable warm dryer ensures a more comfortable experience.

Installation

Just like the TOTO Aquia IV Washlet, the installation of this incredible product requires a 12-inch rough-in into the waste pipe. Its installation can be a little tricky. The water supply should be 11-7/16-inches to the left from the centerline of the closet flange while facing the bowl. Additionally, this toilet comes with a 12-inch rough-in, and mounting and connection hardware.

TOTO Washlet Toilet Smart Seat

Some TOTO Toilets feature a Smart Seat, but what is it actually? It’s a special seat that uses both sensors and WiFi to flush and clean the bowl for you. Some units can even open and close the seat, which brings a modern feeling to every bathroom.

Vespin (Budget Solution)

Vespin is a special line of TOTO toilets that are built for budget and convenience. They usually feature a two-piece design and come with excellent, advanced features. Most of those are made with elongated bowls and a universal seat height.

Special Features

CeFIONtect

It’s a specific feature among TOTO toilets that adds a specific glaze to the bowl. The glaze has two main advantages. At first, it prevents bacteria and mold build-up, making the toilet usage more hygienic. Also, it keeps the toilet clean much longer than a classic model would.

eWater

Some TOTO toilets use special electrolyzed water to quickly disinfect the bowl. It’s the same water that’s used for food preparation products. Basically, toilets with this feature pre-mist the bowl before and after use, with each flush. Also, they eliminate the need to use strong chemicals that would damage the surface over time.

Skirted Design

This type of design usually means seamless shape from bowl to floor, which also makes it easier to clean. There are no traditional curves that make cleaning difficult. Although this design might look minimalist, it perfectly fits any modern bathroom. It also adds elegance and smoothness.

ADA Compliant

Most TOTO toilets are ADA compliant, so what does it actually mean? ADA (American Disability Act) is a set of codes that the product has to meet to be compliant. With ADA compliance, this model is easily accessible for people with disabilities and also children and elders.

Wireless Remote Control

With the Wireless Remote Control, you can access various features without getting up from the couch. For example, you can clean and deodorize the bowl remotely, or even open/close the seat, with just a single button.

Dual-Action Spray

Dual-action spray is a nice feature that reduces your maintenance time. It has a self-cleaning wand, and some models also come with oscillation action. However, you might need to adjust the wand each time, since there is no memory function. Although it might slightly increase the price, the dual-action spray is a must-have feature.

Pulsating Feature

It’s another great feature that this toilet offers – a pulsating and oscillating wash function. Besides, the water is instantly warm, which prevents uncomfortable wash.

Why Should You Choose TOTO Washlets Among Other Options

Most probably, you have already heard many people talking about how great TOTO Washlets are. But what’s so great about these units? Well, at first, let’s say that they are a bit pricey, which is not good. However, most washlets are usually pricey, even much pricier than TOTO models. It means that TOTO washlets will save you a bit of money from the very first moment you buy one.

Then, if you compare these models with any other manufacturer, you will notice the difference in design. TOTO washlets are simply beautiful. They have a plain and sleek design that easily fits any bathroom. Even if your bathroom is a bit old, it will still be a good fit. TOTO washlets are also efficient and use a low amount of water per flush. It means that it will cut your expenses after the very first month of use. Finally, if you care about the environment, buying the TOTO washlet will be an excellent choice. Since they are efficient, they are also great at saving water and preserving the environment.

TOTO Washlet Product Range

Basically, there are 10 different TOTO washlets. It starts with A100 and ends with S350 and S550. You can apply any of these to your existing toilet. Then, another great model is G400. It’s an excellent choice for smaller bathrooms. You can integrate it with the washlet, and it will perfectly fit any bathroom.

Also, you should notice that A100 is the most basic model. The S-series are top of the range, while G400 is a fantastic washlet unit. However, all of these models are “base”. In other words, Toto S350E, for example, has three different models. It all depends on what features do you want in your washlet.

The Primary Features that TOTO Washlets Offer

Basically, every TOTO washlet performs differently. It all depends on which features exactly a given model has. Also, if there are more features, the toilet will also cost more. However, there are some essential features that every model has. For example, they all come with dual-action spray with an in-built oscillating feature. They also allow you to adjust the water temperature and volume and heat the seat. Each device comes with a side control panel, similar to a TV remote controller. Finally, they are all very easy to install and feature a docking station.

Now, let’s mention some other features. These are not mandatory, so some models have them, while some not. Basically, these include an auto-open/close lid, air deodorizer, water pre-mist, night light, and similar. Some units even have wireless remote control and can remember up to two user settings.

Good-to-Have Features

Even the most basic TOTO washlets have all the necessary features. However, while some models might be good for some people, they might not be ideal for others. It mainly depends on your needs.

For example, let’s say that you are a person who cares about hygiene. In that choice, having an auto-open/close feature would be excellent. It provides you with a completely hands-off experience. Another thing to consider is eWater+. We already mentioned that it sanitizes the bowl after each use. Some models even have a self-cleaning wand, which is another big plus.

However, if the odor is a problem for you, there are other features to consider. For example, you might want to have an automatic air deodorizer. It saves time for the next person who needs to use the toilet. Instead of having to wait, the bathroom will be completely fresh and odorless. Be sure to consider your needs and carefully check all the features that a specific unit offers.

What is the Difference Between S350E and S550E?

At the first glance, these two models look very similar. They also have very similar features. So, what is the difference between these models? Well, they mostly differ by their seats. The first model is the slimmest and offers a height of 3-15/16 inches. On the other hand, S550E is thicker and looks similar to Toto S350E.

You might have also noticed that S350E has a round seat. While the seat of S550E is elongated, there is no big difference in actual size. However, there is a slight difference in power consumption, too. While Toto S550E uses around 1300W, S330E uses only 840W. The remote control of the S550E also looks a bit different. It’s a bit slimmer and slightly elongated.

What is the Difference Between G400 and G500?

These two toilets are ideal for smaller bathrooms, especially if you want a flush that uses gravity. They also feature a tankless design, that looks simply amazing. Still, some models such as S350E have better features, but they also come at a different price.

For example, take a look at Neorest, which is excellent, but an expensive model. Then, take a look at some high-end toilets. These two models are right in between. Despite being “400”, it’s actually an upgraded version of G500. Also, it has a pre-mist feature, but costs slightly more. You can’t go wrong by getting any of these two units.

When you check the other features, you will also notice that they are very similar. They have a Tornado flushing system, a comfortable height, and an elongated bowl. Also, they come with an auto-open/close lid and have a built-in air deodorizer. Of course, they both feature wireless remote control.

Avoid the Common Mistake

So, you’ve decided which is your favorite model, and now it’s time to buy. However, don’t rush. At first, make sure that the washlet you have chosen is compatible with your toilet. Avoiding this step is a mistake that most people make. But what exactly do you need to check?

You should check the dimensions of your toilet bowl. Basically, you need to measure the distance between two bolt holes. That’s where the washlet should fit. It might happen that the dimensions don’t fit exactly, but it’s okay. The difference shouldn’t be higher than 0.25 inches.

Now, you should check the distance between the center of the tank and the bolt hole. At first, the distance should be at least 1.75 inches. Also, the surface needs to be completely flat. If the bowl is curved, you might have problems sitting on the washlet.

Read This Before Buying the Washlet

Let’s say that you are a person who pays attention to bathroom style. If you’ve spent lots of money on decor, probably, you don’t want an ugly power cord to affect the style. In that case, buying a unit with a “Washlet+” feature is an excellent choice.

However, those units can also fit on toilets with the same “Washlet+” mark. The good thing is that there are many beautiful units that have the Washlet+ features. For example, you can find some great products in Aquia, Drake, and Ultramax series. So, what is the difference between a regular TOTO toilet and a Washlet+ model?

Well, the difference is very obvious. Next to the two bolt holes, there is an additional hole, but a bit larger. It’s for the power cord and water hose to pass through. That way, they will be hidden underneath the washlet. It’s basically the only difference between a regular and a Washet+ toilet.

Minimum Water Pressure

That’s what people usually need to check when buying a washlet. However, you shouldn’t have problems with TOTO washlets. All their units operate in the pressure range of between 7.25 and 108.75 PSI. Since the minimum is very low, you shouldn’t have problems with that. For example, the average household has a water pressure of between 20 and 120 PSI.

There is one more thing to consider, and it’s volume. If your pressure is fine, but pipes have a small diameter, you will have problems with the volume. It might also be caused due to corrosion. Also, you should know that the maximum recommended pressure in a home is 90 PSI.

You might be wondering how to check the water pressure in your home. It’s actually very simple. You just need to buy a pressure gauge, which you can find in most stores. To measure, just screw the unit onto the hose and turn on the water at maximum. You will get the correct readings in literally half a second.

One Excellent Benefit of TOTO Washlets

We all know that washlets can provide you with many benefits. Better hygiene, cleaner feeling, environment preservation, and similar. However, that’s not the best. Have you maybe wondered what usually causes clogging? It’s toilet paper.

It can build up and jam the pipings pretty easily. Also, people usually prefer strong and soft papers. Although they feel better on the skin, they can cause clogging even more.

It doesn’t mean that you shouldn’t use paper, but that you should use them less. However, especially in large families, it’s easier to say that to do. With a washlet, you will use much less paper, which is an excellent benefit. You might not even need to use it anymore. Simply by buying a washlet, you will get rid of any possible clogging.

Parts of TOTO Washlets

As you know, a washlet is not a complete toilet. It’s more like a high-tech seat that sits on top of the toilet. Although it’s advised to use TOTO washlets with their toilets, you can even mount the TOTO washlet on other toilets. In some cases, at least. However, before you buy a washlet, be sure to check our guide on how to do the proper measurements. Besides, it’s also important to know all the parts that you will get. So, let’s check them out!

At first, you will get a heated seat with a lid unit. Obviously, it should be mounted on top of the current toilet. Make sure that the current toilet is completely flat and has no curves. In that case, it would be difficult to use the washlet. Then, you will get a control panel or remote control. Depending on the model, it will be next to the unit or on the wall. Basically, you can use it for activating water streams, changing water temperature, and similar.

Then, you will get a water filter with a drain. Obviously, it goes behind the toilet, so that the water can reach the spray wand properly. The package will also include a water supply hose that supplies water to the washlet. You will find a water supply port on the unit, so make sure to attach the hose to it. Finally, the package should also include a jet spray wand. It goes below the lid and sprays the water into the bowl.

Additional Parts

These were the main parts that every TOTO washlet should come with. Depending on the model, you might also get a self-cleaning nozzle. Some units might have a nozzle that works automatically due to the sensor. On the other hand, some nozzles can be manually or remotely operated. Basically, the nozzle cleans the jet spraying wand. The wand is built from special materials, such as antimicrobial plastic. Also, it has a silver ion coating, which prevents the growth of various bacteria.

Other Advancements of TOTO Washlets

At first, we should mention the self-contained composting toilets. They use specific bacteria from the waste, combined with elements from the container, and break down the waste further. It uses no water at all!

Then, we have Sani-Seats. These seats are also mounted on top of the toilet, like a Washlet. However, instead of cleaning the person, they clean themselves. There is a special sensor that detects the user and provides a completely new surface for seating.

In the end, TOTO also sells a self-cleaning single stall. It’s a bit larger than a portable toilet and completely cleans itself in less than two minutes. However, they cost literally half a million dollars, which is too much for everyone.

Certifications of the TOTO Washlet

When buying a new toilet, it’s crucial to check which certifications it has. One of the most significant certifications of this model is EPA WaterSense. It means that using a minimal amount of water, it provides optimal flush performance. It decreases your monthly bills and saves the environment.

Additionally, TOTO Washlet is certified by CSA, IAPMO, Legislative Compliance in California, as well as Los Angeles Water Efficiency Ordinance.
