Best TOTO Washlets (Packed Technology) Review of 2023

1. 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 for you, which brings a modern feeling to every bathroom.

2. CeFIONtect

This special toilet glaze has two main advantages. First, it prevents bacteria and mold build-up, making toilet usage more hygienic. Second, it keeps the toilet clean much longer than a classic glaze would.

3. Skirted Design

Available with many TOTO models, this type of design refers to a seamless shape from bowl to floor. There are no traditional curves so it is easier to clean.  Although this design might look minimalist, it perfectly fits any modern bathroom, adding elegance and smoothness.

4. ADA Compliant

Most TOTO toilets are ADA compliant. ADA compliance assures the model is designed to be easily accessible for people with disabilities. In particular, ADA compliant toilets will be taller than the typical toilet, making them easier to sit on.  

5. Wireless Remote Control

With the Wireless Remote Control, you can access various features even from outside the bathroom. For example, you can clean and deodorize the bowl remotely, or even open/close the seat, with just a single button.

6. Dual-Action Spray

Dual-action spray is a nice feature that reduces your maintenance time and increases flexibility of the Washlet. It includes a self-cleaning wand, and some models also come with oscillation action. Unfortunately, you might need to adjust the wand each time, since there is no memory function. However, for a customized spray each time, we think this feature is well worth the cost.

Model Comparisons

There are 10 different TOTO Washlet models to choose from starting with the A100 and ending with the S350 and S550.  The G400 is an excellent choice for smaller bathrooms. 

When choosing a unit, note that A100 is the most basic model. The S-series, then, are top of the range. Which model is best for you all depends on which features you want in your Washlet.

1. TOTO S350E vs. TOTO S550E

At the first glance, these two models look very similar. They also have very similar features. So, what is the difference?  

The first model is the slimmest while the S550E is thicker. Also, the S350E has a round seat while the seat of S550E is elongated, although there is no big difference in actual size. There is a slight difference in power consumption, however. While Toto S550E uses around 1300W, the S330E uses only 840W. Also, the remote control of the S550E is a bit slimmer and slightly elongated.

2. TOTO G400 vs. TOTO G500

These two toilets are ideal for smaller bathrooms, especially if you want a flush that uses gravity. They both feature a tankless design that looks simply amazing. The features on both of these units are very similar. They feature 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. Some models such as S350E have additional features, but they also come at a higher price. Because these units are both so similar, you can rely on your personal preference for the price, look, and smaller details to select the right option for you.

Avoiding Common Mistakes

Before you buy your favorite TOTO Washlet model, make sure that the unit you have chosen is compatible with your toilet.  What exactly do you need to check?

Toilet Fit within your Bathroom Space

You should check the dimensions of your toilet bowl. Measure the distance between two bolt holes, which is where the Washlet should fit. If the dimensions don’t fit exactly,  it’s okay as long as the difference is not higher than 0.25 inches.

Then, check the distance between the center of the tank and the bolt hole. 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.

Minimum Water Pressure

All units operate in the pressure range between 7.25 and 108.75 PSI. The average household has a water pressure between 20 and 120 PSI. Since the minimum requirement is very low for the Washlet, you shouldn’t have any problems.

If you need to check the pressure in your home, you will need to buy a pressure gauge, which you can find in most home improvement stores. To measure, just screw the unit onto the hose and turn on the water at maximum. You will get the correct readings very quickly.

 If your pressure is fine, but pipes have a small diameter, you still may encounter problems with the water volume. These problems could be caused by corrosion, which would require help from a plumber to fix.

Parts List

On its own, 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 TOTO toilets, you can mount one onto other toilets. However, before you buy a Washlet, be sure to check our guide on how to do the proper measurements.

Let’s take a look at what is included with these units.

You will get a heated seat with a lid unit that should be mounted on top of the current toilet. Make sure that the current toilet is completely flat and has no curves. The Washlets also comes with a control panel or remote control. Depending on the model, it will be placed next to the unit or on the wall. You can use it for activating water streams, changing water temperature, etc.

Next, you will get a water filter with a drain that goes behind the toilet, so that the water can reach the spray wand properly. The package will also include a water supply hose. 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 that goes below the lid and sprays the water.

Additional Special Parts

Depending on the model purchased, the package may also include a self-cleaning nozzle. Some units might have a nozzle that works automatically due to the sensor while others can be manually or remotely operated. 

What about Installation?

Just like the TOTO Aquia IV Washlet, the installation of this incredible product requires a 12-inch rough-in into the waste pipe.  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. Depending on the model, you may want to work with a professional for the installation of your TOTO Washlet.

Certifications

Many TOTO Washlets offer EPA WaterSense certification which means that they use a minimal amount of water while providing optimal flush performance, decreasing your monthly bills, and helping the environment.
