Product Description

Quick Note:  The TOTO S550e and TOTO S500e are identical, except that the S550e has an automatic opening/closing lid and LED night light.  Besides that, the two models are exactly the same.

Released in January 2018, the all new TOTO S550e Washlet is TOTO's newest bidet toilet seat offering, replacing the previous generation TOTO S350e.  This TOTO washlet sports an all-new body design that is available in two styles - Modern and Classic.  The difference between these two styles is the lid - the Modern style has a more minimalist and cleaner looking lid, while the Classic style has beveled edges going around the corners of the lid.  Two different looks, but the same great washlet underneath.

Equipped with both feminine and rear wash functions, this bidet seat offers outstanding cleansing performance.  The washlet's built-in water heater provides a warm water wash at a temperature you control.  Water pressure can be adjusted as well.  The position of the spray nozzle can be adjusted more forward or more backward for optimal coverage.  Using the oscillate feature will automatically extend and retract the nozzle, back and forth, providing a greater cleaning area.  When done washing, activate the hands-free warm air dry to help dry off any residual moisture from your wash.

Some unique features you'll find on the TOTO S550e include the automatic opening and closing lid.  A body sensor on the washlet detects when you approach the toilet, and will raise the lid for you.  Men - who may want to raise the seat too, can do so by tapping a button on top of the remote control.  The washlet detects when you walk away, and will slowly close the seat/lid for you.  The e-Water feature uses electrolyzed water to pre-mist your toilet bowl before using the toilet.  This assists in keeping your toilet bowl clean with every flush.

The remote control comes with an all-new design as well.  Some of the buttons previously found on the sides of the remote have been moved to the front for easier operation.  It is also a bit thinner, making it easier to hold in one hand.  Two user-preset buttons can be found at the bottom of the remote which allows you to pre-program settings such as water temperature, water pressure and nozzle position for up to two people in your household.

Available in Cotton White and Sedona Beige.





TOTO S550e Washlet Features:



Editor's Review:

The TOTO S550e washlet comes in your choice of two styles, "Modern" or "Classic" - which determines the type of lid your bidet seat comes with.  Keep in mind this unit features an automatic open/closing lid, so your lid will almost always be closed.  And because of this, the type of lid you choose has a huge influence on what your washlet will look like in your bathroom.  The "Modern" lid has a cleaner, minimalist look while the "Classic" lid is busier - with beveled edges going around the contour of the lid.

Once you get underneath the lid though, everything else is the same.  The base unit and features are exactly the same no matter which style you choose, so it is strictly an aesthetic choice.

The TOTO 550e washlet features both feminine and rear wash functions.  Both water pressure and water temperature can be adjusted.  The bidet has a tankless, on-demand water heater built right into the seat which provides a continuous warm water wash.  You can adjust the position of the spray by adjusting the position of the wash nozzle more forward or backward.  There is also an "oscillate" function which automatically moves the nozzle back and forth, extending the cleaning area.  Also available, is a "wide" spray function which sets a larger radius for increased coverage.

All of these features are controlled through the use of the wireless remote control.  A wall mounting kit is included, so you can conveniently mount the remote on the wall next to your toilet.  Buttons for the most commonly used features - such as wash, oscillate, stop and dry are all located on the front of the remote.  On the back of the remote, you can adjust more advanced features such as the eco-power saving modes and strength of the air dry fan.  Once you get your initial setup done, however - you'll be using the front of the remote 95% of the time.

Most of the bidet seats you come across will have the basic features of feminine/rear wash, adjustable water pressure/temperature, adjustable spray, and warm air dry.  What really sets this bidet seat apart though, are the non-wash features.  These non-wash features are what really makes the TOTO S550e a "smart" toilet seat.  Let's start with the automatic open/close lid.  A body sensor detects when you're approaching the toilet and will raise the lid for you.  And for men - tapping the button on top of the remote will raise the seat too.  Both the seat and lid will automatically close when you walk away.

The included LED night light turns on and off using this same body sensor.  So the toilet lights up for you when you walk towards it, and dims when you walk away.  We also note that you can customize these settings thru the remote control.  So you can de-activate your lid from opening by itself, or de-activate the night light if you so choose.

Then there's the eWater, or electrolyzed water feature.  Electrolyzed water was originally used in the restaurant industry, used to disinfect knives, utensils and cutting boards.  The TOTO S550e uses eWater to pre-mist your toilet bowl before you go to the bathroom.  Pre-misting your toilet helps prevent material from adhering to the sides of the bowl, and increases flushing efficiency.  The washlet then mists your toilet every 8 hours which further helps keep your toilet clean, and reduces the need for scrubbing your toilet with harsh chemicals.

The heated toilet seat is another popular feature.  Sitting on a freezing cold toilet seat is not the best way to start your day.  The temperature of the seat can be adjusted as well, and of course - you can turn it off during the warmer months of summer.  A built in air deodorizer is also included which works with active carbon filtration, helping to filter bathroom air of unwanted odor.  An occupied seat sensor works as a "safety," which means none of the wash functions will work unless you are sitting on the seat.  This helps prevent your three-year old toddler from accidentally activating the spray.

This very well-thought out design and feature set makes this model one of the best bidet toilet seats available.  If you're looking for the best seat money can buy, then look no further.  The TOTO S550e is the washlet for you.
