TOTO S350e WASHLET Features Overview

TOTO S350e Washlets Features

Main Features:

The TOTO S350e comes with a classy, slim wireless remote, complete with illuminated touch pad.  This remote has common features on the front, allowing guests to easily select these features when the remote is on the wall, and more complex features on the back, allowing you to remove the remote from the mount for more luxury, or complex wash cycles.

The wireless remote also allows you to configure two user wash settings, allowing to select your favorite wash with the push of a single button.

The TOTO S350e WASHLET is sleek and slender, measuring just under 4 inches thick


Sanitary Features:

The TOTO S350e offers self cleaning nozzles like many of the other bidet seats on the market do, but takes this to the next level with EWATER+.  This EWATER+, or electrolyzed water is more sanitary, and allows the cleaning process to do it’s job to the full.

The S350e also runs EWATER+ over the bowl before each use, for additional cleanliness.


Luxury Features:

Aeration refers to infusing air bubbles into the water stream.  This is done to make the stream softer and more gentle.  It’s no surprise that the TOTO S350e offers this feature at it’s best.

The TOTO S350e also offers adjustable warm water, using it’s high end instant water heating system.  This system provides unlimited warm water while using less energy than similar seats on the market today.

The oscillating feature offered on the TOTO S350e WASHLET causes the wand to move from side to side, providing a more complete wash.

If you’re looking for a wider wash, but not one as wide as the oscillating wash provides, the TOTO S350e offers a wide wash function to provide a wider wash then normal, without going to the extreme of the oscillating wash.

The TOTO S350e WASHLET also offers a pulsating wash.  This wash toggles the wash stream between high and low pressure multiple times a second.  One of the main uses of this particular wash cycle is to stimulate bowel movements.

As expected, the TOTO S350e comes with the option to adjust the wash pressure, allowing you to get the wash just right.

The warm air dry feature offered by the TOTO S350e offers five different temperature settings allowing you to tailor it to your liking.

The TOTO S350e also comes with a built in active carbon filter.  The built in fan pulls air from the toilet bowl through this filter.  The filter then absorbs the odor, and the air comes out odor free.

The TOTO S350e is one of only a couple bidet seats that offer an auto open and auto close lid.  This feature is the ultimate in luxury, allowing the operator to keep their hands totally clean through the whole experience.

The heated WASHLET seat on the TOTO S350e is fully adjustable, allowing the operator to customize the temperature to their liking.

The night light offered on the TOTO S350e makes using it at night a pleasant experience.


Other Features:

TOTO offers a quick release feature, which they refer to as the Docking Station.  This makes cleaning the S350e very quick.

TOTO offers a one year warranty for the S350e

 TOTO S350e Washlet Star Rating

TOTO is a high end, high quality brand.  All the bidet seats we offer are high quality, but from what we’ve found, TOTO is hard to beat.  They use only the highest quality parts to make high end products.  TOTO offers all the features you’d want on the S350e, including EWATER+, auto open lid and seat, and much more.  This seat earns a feature rating of 5 out of 5 stars from us due to all the great features it offers.  The warranty is one area that this seat is lacking in, with only a one year limited warranty.  This along with its high price earns it a value rating of 4.2.  Overall, if you’re looking to get a great seat, and you have the money, we highly recommend this WASHLET.

Editor’s TOTO S350e WASHLET Review

toto-s350e-washlet.jpgThe TOTO S350e WASHLET is the top of the line.  The TOTO S350e not only offers all the features other seats offer, but it also offers some additional features no other seats on the market currently offer.  From it’s one of a of a kind EWATER+ system, to auto lid opening, this WASHLET has it all.

The wireless remote on the TOTO S350e WASHLET is much sleeker than on earlier models, while offering the same functionality that only TOTO offers on a wireless remote; hidden features.  On the old models, the front of the remote control had a flap on it, hiding the more advanced features, while still allowing normal features to be used.  This allowed guest in your house to use the remote without being overwhelmed.  However, due to the cover, many people felt like the remote looked and felt bulky when the cover was closed.  The remote control for the TOTO S350e solves this problem by including buttons on the back of the remote.  When guests use the bidet, they will simply access the buttons on the front of the remote control, from where it’s mounted on the wall.  You still get the benefit of all the features, simply by removing the remote from its mount, and accessing both sides.  This keeps the remote from being bigger than it needs to be, but still offers your guests a simple and easy experience.


We’ll talk about the front of the remote first.  These are the options your guests will probably use.  At the top, we have the option to open and close the seat.  Next, we have the stop button.  Keep in mind however, that the TOTO S350e WASHLET also has a seat sensor.  If you or a guest gets up mid-wash, the WASHLET automatically turns the wash cycle off, cleans the wand and nozzle, and goes into standby mode.  Both the Rear and Front options on the front of the TOTO S350e WASHLET remote have two options available to your guests.  Rear options for the TOTO S350e are listed first.  With these options, you can choose between Soft Rear, which sprays with a soft, mild water pressure, or simply rear, which sprays with a stronger water pressure.  Next, we have the option for Front, which offers a normal bidet spray to the front, for women, and a wide front option, allowing for a wider, more thorough clean.  After these options, we see a button for Dryer, which simply dries you with warm air.  The last option on the front side of the wireless remote control for the TOTO S350e is User Personal Settings.  This allows you to set up more complex wash cycles and save them as presets.  TOTO puts these on the front of the TOTO S350e WASHLET remote control for easy access.

All of the options talked about above are shown on the front of the remote control.  These options are very simple and very guest friendly.  There are no options for water pressure, temperature, or any of the other more complex features.  However, the two user defined options on the front of the remote allow you to still use the more complex features at the click of a button.

The sides of the TOTO S350e remote offer additional settings and features.  All of these features work with the four wash settings available on the front of the remote control.  On the right had side (when looking at the front of the remote) there is the Oscillating button.  This option causes the wand to move back and forth, washing the rear more thoroughly.  Hitting the Oscillating button on the TOTO S350e WASHLET toggles it between on and off.  The secondly, on the right had side, we have the position button.  This option allows us to adjust the nozzle more precisely after we’ve chosen front or rear wash.  On the left hand side of the remote, the pulsating button tells the nozzle to toggle or pulsate between soft and strong streams.  Clicking this button toggles this feature between on and off.  Lastly on the left hand side, are the pressure adjustment buttons.  These buttons allow you to determine the pressure of the stream, allowing you to have a very powerful, or very soft wash, depending on your preference.

On the back of the remote, TOTO puts the more complex features.  These features are only visible if the TOTO S350 wireless remote control is removed from its wall mount.  On the top of the wireless remote, you’ll see a display panel, showing you the current temperature settings for the water, the seat, and the air dryer.  Below the TOTO S350e remote control display panel, are located arrow keys, an enter button, and a menu and temp button.  This temp button adjusts the temperature for either the water, seat or dryer, depending on which is selected on the display panel.  When the menu button is clicked, the display panel updates, giving you cleaning options, energy saving options, auto function settings, and other settings.  Moving through this menu allows you do adjust a variety of different settings from having the lid auto open, to night light settings, to energy saving settings, to EWATER+ settings and much more.


The TOTO S350e WASHLET and TOTO S300e WASHLET are the only WASHLETs currently on the market that offer EWATER+.  This high tech cleaning method puts TOTO well above other bidet manufactures in the market today.  This is hypochlorous water is generated from chloride ions in tap water via electrolysis.  The TOTO S350e WASHLET creates this electrolyzed water automatically, and washes the toilet bowl, nozzle and wand after each use with this water, making it the cleanest, most hygienic bidet in the world to date.  For more information about EWATER+, please watch our informational video under the additional resources area of this page.

EWATER+ is not the only thing that makes TOTO unique.  The TOTO S350e WASHLET also offers automatic lid and seat, giving you the ability to use the restroom without ever touching areas of the toilet that might be extra dirty.  This is a feature few other bidets in the world can offer.  The TOTO S350e WASHLET also heats the water while you use it, allowing you to have instant and unlimited hot water, making it the perfect choice for a busy bathroom.

The deodorizer the TOTO S350e WASHLET uses is second to none.  Unlike common air fresheners that mask the smell of a restroom, the TOTO S350e deodorizer filter absorbs the smell using an active carbon filtration system.  The air is pulled through this filer using a fan, and comes out the other end clean and free of smell.  This gives you a much better experience then you can receive from an air freshener that simply masks the smell.
