Features of Toto Washlet S550E



Once you have seen the TOTO S550e, the very first noticeable thing is just how nice it appears.

The cover was split more toward the back on older generation units (e.g., the S350e and S300e), leaving the LED light and sensors mostly on seats visible even though the cover was down.

With the S550e, TOTO took a new tactic, designing a lid that covers a wide seat area from rear to upfront. The curves of the top, and how it glides smoothly from rear to front, are quite appealing.

The design language is the main highlight of S550e.

The top, which can now be bought in two designs – classical and modern – is yet another latest design feature of the TOTO S550e model. The modern lid design is a trendier, sleek style that appears to be incredibly clean.

As the quote goes, smaller is better, and this is certainly true here. The classic lid design has curved edges, tapering off as you go nearer to the sides. The clean lines of modern architecture give it a more modern/current appearance. With its curved top, the traditional design gives it a more classy/fancy appearance.

In this toto bidet review, we remind you that the coverlid seems to be the ONLY distinction between both the modern and vintage models. It is the same washlet behind the cover, irrespective of which type you pick – it is just a matter of personal style and bath decoration. The modern and classic designs have the same selected features.

The Toto S550e is super-thin, at only 5” high at its highest point in the back. Because so much of the equipment (e.g., freshwater pump, heating system, spray gun, drying blower) are placed also at the back of the seat, the back of a toilet seat has always been the highest point. The incredibly narrow design contributes to the bidet’s premium look.

When you open the lid, you will notice some led lights at the rear of the seat. Toto has fixed 4 lights that indicate the energy, radiant heater, energy-saving, and Water purification function of the bidet.

Wireless Remote Control

This Toto S550e bidet seat has a cordless remote controller that is useable on both sides to operate its various functions. The remote has a build of strong plastic, unlike most mediocre remote controls, yet it seems to be polished steel in photographs and movies.

Toto S550E Wireless Remote Control

The first thing you will notice in the remote is that it has control on both sides, as well as on the top of the remote.

The Toto s550e review tells you all about the wireless remote and how to use it.

There are extra symbols beside the back rinse and women rinse symbols that glow up when the broadening spraying option for those functions is engaged. The regular wash works by clicking backwash once, while the wide/soft spray starts by hitting the rear wash twice.

Touching it again returns it to the regular rinse setting, and so forth… As you continue spraying, it functions like a “switch” that switches between both the normal spraying and the broad spraying.

Modification settings for water flow and sprayer angle are found at the base of the remote. These changes are made with a “slide,” thus sliding left lowers pressure and sliding right raises it.

Sliding left on the sprayer angle modification brings the sprayer back while swiping right brings it at the front. The symbols represent multiple user preferences at the base of the controller.

The screen on the rear of the remote pops up after flipping it over. A few controls are located beneath the Led screen, these are physical buttons that you have to press not like the other touch screen controls.

You can easily notice the usual buttons, as well as an “Enter” key in the center, all of which come in handy to browse the interface. The backside of the remote contains all temperature settings, including the temperature of the water, seating temperature, and air-drying temperature.

You may also modify environmentally friendly choices and program user preferences here, as well as enable automated features (e.g., auto-open/close seat/lid, automatic light switch, auto water-flow settings).

Lastly, a control at the left side of the remote is used to lift the seat.  The TOTO S550e has an auto-opening lid that rises as you reach the seat. This switch of the remote is also used to elevate or lower the seat.

Bidet Features

The washlet in this TOTO S550e toilet comes out around single-extending nozzles with three spraying openings at the tip of the nozzle. The normal backwash comes out through the first spray hole.

The wide/softback rinse comes out through the center sprayer outlet. Both regular and broad female washes come out through the final spray port nearest to the nozzle’s tip.

There are several distinct options for water flow and tip angle. The water temperature is changeable in six different ways, extending from 87 to 105 F. If you would like, you can pick normal temperatures of water with no heating.

The Toto s550e review explains all the bidet features in detail.

The rotating shower function extends the washing region by moving the nozzle backward and forwards. You may also choose the vibrating rinsing function, which massages the skin by pulsing the flow of water.

If you choose, you may utilize both the vibrating and pulsing water settings at the same time.

The Toto S550e has an automated lifting and shutting seating and cover, as told in the above section, So  Whenever you reach the bathroom, the wash lets’ body senses your presence and raises the cover for you.

Men wanting to elevate the seat can do this by pressing a key on the remote control’s upper part. When you walk away from the seat, it will sense your absence and automatically bring down the lid after 90 seconds.

Now we are about to discuss the main highlights of the Toto s550e review or why you should buy it, and why not. There are different people with different toilet preferences so you can check out if this one fits your needs or not.

What to Look for in a Bidet



Bidets directly come into contact with your skin so cleanliness is a very considerable factor.

Luckily, the Toto washlet s550e is equipped with many features that help to keep it clean.


I guess you are hearing this term for the first time, it is a special Toto s550e feature that will spray the bowl with water, every time you are going to use the toilet. Every time you are going to use the toilet, this will spray the bowl with water.

This keeps feces from clinging to the bowl and having to be cleaned afterward. We believe it is a fantastic feature that cuts a substantial amount of time.


EWATER+ is a special feature, which washes the entire bowl and hoses each time you use the toilet. It has a unique yet fully safe cleanser that disinfects everything else in the commode, cleaning it up and reducing your effort.

You will hardly ever have to wipe your toilet if your bidet has EWATER+ and PREMIST features! Toto washlet s550e comes with both of these features and a lot more to ease your life.

Self-Cleaning Nozzle

Almost all of the Toto bidets contain self-cleaning nozzles. After each usage, these nozzles wash so you would not have to worry about unpleasant stains forming.

Air Deodorizer

TOTO s550e bidet has air deodorizers integrated. These purify and freshen the atmosphere in your toilet, ensuring that everything remains fresh and odor-free.

Automatic Lid

This is one of the greatest TOTO s550e features in my opinion. The automatic lids have a detector that identifies you as you come and automatically opens the top. When you complete your job, the system will sense your departure and close the lid immediately.

This gives you hands-free pleasure, especially because you will not have to clean your hands! However, you should clean your hands.

Memory Settings

To obtain deep cleaning with a bidet brush, it must be precisely positioned. It might be annoying and time-wasting to try to get a great fit every time. That is your destiny on certain bidets.

On the Toto washlet s550e, user preferences can be saved in the memory.

With the touch of a button, you may remember your perfect settings and come to the same spot each time.

Final Verdict

Toto Washlet S550E Full View

 Toto S550e review tells that is a good investment. If you can afford it, then the conclusion is a hearty “yes.” You cannot get any better option than this on the market.

It is the most lavish bidet seat available, supplied by the world’s premier bidet producer.

Finally, yet importantly, the Toto S550e is among the few bidet options that entirely remove the need for toilet paper for most persons.

One of the fundamental issues with all bidet seats is that they only lower the demand for toilet paper by a significant amount.

Although these kinds of equipment are the most effective at entirely removing the need for toilet paper, they aren’t nearly as handy or enjoyable as a Toto Washlet.

I can assure you that the Toto S550e review provides you with the best opportunity of totally removing Paper waste from your toilet. So never hesitate to try that.
