Using a toilet every day is the basic necessity of every human being. So why not upgrade the existing toilet with a Toto washlet S500E for some extra comfort?

Electric bidet toilets are on the rise in modern households. This is not surprising because an adjustable water jet cleans more thoroughly and gently than toilet paper, resulting in environmental protection.

The S500E Toto washlet can be installed over the existing toilet in your home without any significant installations. Once installed, it has so many functions that you would love to use it, and who knew using a toilet can be so much fun with the Toto washlet.

Our Toto S500E review gives you valuable background information that should make your purchase decision easier. We will also introduce you to this variant of electric bidet seat and explain for what purpose they are best suited.

What Is a Bidet Toilet Attachment, and What Benefits Toto S500E Has?

Before we start our Toto S500E review, let’s take a quick look at what a bidet toilet attachment really is and what benefits can you get from it.

Bidet toilet attachment seats are much more convenient than modular electric toilets. They are attached to your existing ceramic toilet and become a part of it. In addition, they are mostly powered by electricity.

The contemporary lid design of the Toto S500E has sleek and modern looks with a boatload of features. Installing this bidet toilet seat is as simple as possible, and if you love DIY, you don’t require an extra set of hands.

The PREMIST and EWATER+ functions work as a self-cleaner and keep everything inside the toilet sanitary. Once the Toto S500E detects you, it sprays the toilet with electrolyzed water that not only disinfects the toilet but moistens it to prevent any material from sticking to it. 

The self-cleaning feature of this electric bidet toilet seat cleans the wand before and after use and every 8 hours of non-use.

Buyers Guide

After going through the Toto S500E review, let’s take a detailed look at the buyer’s guide. Here we will discuss what to look for before making an essential purchase.

The Shape of the Bidet

First things first, it is essential to know the shape of the bidet toilet you want to attach the Toto S500E washlet to. As bidets come in two shapes that are either round or elongated. The most common shape these days is elongated, and if your toilet has an elongated shape, you are good to go. 

On the other hand, the S500E Toto washlet cannot be attached to a round-shaped bidet toilet because of its elongated make. The reason for that is if fitted to a round shape, it would possibly not work, and the product might get damaged.

Power Outlet

The Toto S500E washlet is an electronic device and requires a power outlet with a 120V. So make sure that there is an appropriate power source located near the existing bidet toilet. If you don’t have a power outlet near the existing toilet, make sure you install one professionally.


The Toto S500E washlet seat is designed to be attached to an existing bidet toilet.

It requires removing the old seat, installing it in a few simple steps, and attaching the water hose and power. It can be done by DIY, but if you are not sure, you can call for a professional to install it. Make sure the adjustments are correct according to the user manual for proper usage.

Warranty and Brand Reputation

Checking for a warranty is essential before purchasing any product, which applies to the Toto S500E. Although Toto has a brand reputation and their products are built to last, it’s safe to have a warranty anyway. The manufacturer provides a 1-year limited warranty for this model and offers service for repair beyond the warranty date.


As a rule of thumb, comfort and luxury come at a price. For a quality product that offers all this with convenience in your life, then spending a few bucks is a brilliant idea. Toto S500E might be a little pricier, but it is reasonably priced compared to its competitors. So make sure you spend that money at your convenience according to your budget. 

Final Verdict

After much research on electric bidet seats and giving a worthy Toto S500E review. We conclude that it is the best electric bidet seat attachment in terms of functionality and its value for money. Its features such as PREMIST, EWATER+, Soft Close, water heating, different cleaning functions, air drying, and deodorizer are unmatched, and we liked them the most.

In addition, it is easy to install.

It couldn’t be any simpler to use due to its one-touch setting via wireless remote control.

Q. Can children use the S500E washlet?

Yes, after a short introduction, children aged 4 and over can use the Toto S500E washlet. However, you should first explain precisely how the toilet should be used with smaller children.

Q. Is using the S500E washlet seat uncomfortable?

No, most people find them comfortable. But start with the lowest water jet strength and increase gradually. You can start with the temperature in the middle range. This is how you will find the optimal setting for you.

Q. Is the use of toilet paper completely eliminated?


Yes, the Toto S500E has an air-drying feature.

But even though it has a built-in air dryer, the drying process takes some time. In addition, due to some medical conditions, toilet paper cannot be used, so it is welcoming to have an air-drying feature.

Q. Is the shower nozzle soiled when using the toilet?

No, because the shower rod is only moved out of the shower toilet for the showering process and is positioned so that no contamination occurs. Before and after use, the water jet is cleaned by a self-cleaning feature.

Q. How is the shower function triggered?

The shower function is triggered by pressing a button on the remote control once you finish.

Q. How long does the cleaning process take?

The cleaning process usually takes 20 seconds. However, you can start and stop the process as you wish.
