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.
