Design

As always, we’re going to begin the review by taking a look at the appearance, dimensions, and built of the Washlet.

The first thing you will notice when looking at the S300e is the slim design.  When you compare it to the entry- or mid-level toilet seat bidets made by Toto, such as the C100 or C200, the S300e is significantly slimmer.  It measures just under 4” at the tallest point at the back of the seat, whereas the C100 and C200 measure over 7”.  The S300e is available in elongated or round versions.  The dimensions for the elongated seat are 20-3/4” long, 15-3/10” wide, and 3-15/16″ tall.  The dimensions for the round seat are 18-7/8” long, 15-3/10” wide, and 3-15/16” tall.

Toto Washlet S300e Dimensions

The S300e is operated by a remote control, similar to other top-level bidet toilet seats.  It is powered by two AA batteries.  Given its slim design and the use of a remote control, the S300e is the most compact toilet seat bidet you can purchase.  The remote control receiver is located on the right corner of the toilet seat.  Next to it is a removal button to detach the unit for cleaning the toilet bowl and the deodorizing filter.  The LED light indicator display can be found on the top left of the toilet seat.

As for the remote, there are two sides.  The front side has the buttons “Stop”, “Rear” cleansing (including “Soft Rear”), “Front” cleansing, “Oscillating” (wand moves back and forth to get a more thorough clean), “Pulsating” (water pressure alternates between soft and strong), and “Dryer”.  You can use the remote to adjust the pressure and position of the water and wand during cleansing as well.  The one thing worth mentioning about the remote is the personal setting buttons.  You can store the preferred wand position, water pressure, and water temperature for two users.  On the back side of the remote, there is a display of the temperature settings for water, seat, and dryer, and a “Temp” button to adjust their temperatures.  There is also a “Menu” button that you can push to select the settings for “Wand Cleaning”, “Auto Energy Saver”, “Timer Energy Saver”, “Pre-mist”, and “Deodorizer”.

Features

First, we’re going to take a look at the more advanced features you can find in the S300e, and then we’re going to go through the more basic features that you will find in all the Toto Washlets we have recommended and reviewed.  Because it’s an advanced bidet there’s a lot to talk about in this section!

The first advanced feature we want to talk about is the ewater+ system.  “ewater+” is Toto’s way of saying electrolyzed water.  Electrolyzed water is ordinary tap water that contains sodium chloride and is a disinfectant, cleaner, and sanitizer more effective than household bleach.  You can think of it as salt water that has been passed through an electric current.  It is a safe way to kill many bacteria and viruses.  It’s even safe to drink (if you don’t mind the taste)!  Because of its non-toxic properties many food preparation facilities and hotels use it to clean.  The problem is the electrolyzed water can’t be stored for long because it loses its potency.  However, Toto developed a way to integrate that into its toilet seats, by having regular water turn into electrolyzed water each time the toilet flushes.  When you stand up from the toilet, “ewater+” sanitizes the wand automatically and is sprayed into the toilet bowl.  Plus, to make things even cleaner, the S300e has a Pre-mist that is sprayed as you approach the toilet to make it difficult for dirt to adhere and a Deodorizer which starts when you sit down.  All in all, the S300e one of the cleanest, most easiest to maintain toilet seat bidet ever.  These keep-clean functions work by sensors located on the toilet seat, which detect your movement.

The second advanced feature we want to talk about is the Timer Energy Saver.  This function is added on top of the Energy Saver feature, which is present in all the Toto products we’ve reviewed.  This feature helps conserve energy during times when the toilet is used less frequently.  The Energy Saver is a smart function.  It automatically determines the periods when the toilet is used less frequently and not at all.  It takes about 10 days for it to recognize your toilet habits, and it will automatically launch into energy saver mode if you have the setting turned on.  During periods of infrequent use, the Toto Washlet S300e will lower the toilet seat temperature to save energy.  On the other hand, the Timer Energy Saver allows you to be in complete control of when you want the heated seat to be completely off.  If someone happens to use the toilet during this time, the toilet seat heater will turn on temporarily, but it will take 15 minutes to warm up.  You can set both the automatic Energy Saver and Timer Energy Saver on at the same time.  For instance you might want to set the Timer Energy Saver from 8am to 5pm when nobody is home, and have the Energy Saver running so that it automatically lowers the temperature during times when the toilet is not used at much, such as from midnight to 6am.

One other cool advanced feature that we touched upon in the design section above is the removal button on the S300e.  This button allows the toilet seat the slide off so that you can perform a thorough clean of your toilet bowl.

Now for the more common features.  There are four dedicated cleansing modes: Rear, Soft Rear, Front, and Wide Front. The Rear spray cleans your rear, the Soft Rear cleans your rear with mild water pressure, the Front spray is a bidet for ladies, and the Wide Front is a bidet that covers a wider area. While using each of these sprays, you can turn on the oscillating feature which will move the wand back and forth to wash more thoroughly. By turning on the pulsating feature the water pressure will alternate between soft and strong, which feels as if you’re being given a massage.

The cleansing functions of the S300e Washlet are highly customizable.  You can adjust the water pressure and washing position with the buttons located on the left and right side of the remote.  They can be adjusted to 5 different water pressures and 5 different positions.  You can also adjust the water temperature.  The minimum water temperature is 86°F/30°C and maximum water temperature is 104˚F/40˚C.  Many years ago, when Toto first designed bidet toilet seats, they discovered that the ideal temperature was around 38˚C.  If you like a good story about invention you can read about how Toto invented the Washlet here.

Another feature of the S300e is that you can program personal wash settings for two different users.  You can store a user’s choice of wand position, water pressure, and water temperature.  To store these settings, simply press and hold “User 1” or “User 2” while cleansing is in progress.  When you want to use the settings, you just press the appropriate User that has your settings stored.

The Washlet has an air dryer that is customizable as well. You can adjust its temperature from low, which is about 95°F/35°C, to high, which is about 140°F/60°C. The adjustable heated seat has a surface temperature between 82˚F/28˚C to 97˚F/36˚C. You can turn the heated seat completely off or on auto energy saver mode which sets the seat to about 79˚F/26˚C.

You can wipe the wand down using the wand cleaning feature (this is different from the auto wand sanitization with “ewater+”).  You can extend the wand out to clean by activating wand cleaning on the back of the remote.  It’s recommended to clean the nozzle monthly or when you notice dirt.  The wand will automatically retract after five minutes.  Use a soft, wet cloth to wipe the wand.  Be careful not to pull, push, or press the wand with excessive force as this can cause damage.  When you’re finished you can use the remote to turn it off.

Finally, many people ask this question: Do you need a hot water supply?  The answer is no.  The toilet seat heats the water.  But you will need to plug the seat into an electric outlet.

Why the Toto S300e?

Buying a bidet toilet seat is a huge investment, let alone a luxury one. Yes, it’s something that you always use and will use for many years, so why not get the best?  On the other hand, is it worth spending the extra money on advanced features?  To help with your decision, we put together some reasons why the Toto Washlet S300e might suit your needs.

You should buy the Toto Washlet S300e if:

  • You like the Toto brand and quality

Drawbacks

It’s hard to find many drawbacks about the S300e, unless we nitpick.  If we had to pick something we would probably say that it takes some adjusting to the noise.  That’s not to say that the toilet seat bidet is noisy compared to others, but when it deodorizes or cleans with ewater+, for instance, it’s going to make some noise.  It’s a machine after all.  We would say that it’s a small problem if someone uses the toilet in the middle of the night when every noise sounds 100 times louder than it really is.  And if it’s something you can’t adjust to, we recommend turning some of the noisier features off.

Final Thoughts & Where to Buy

The Toto Washlet S300e is a slim, futuristic toilet seat bidet jammed with advanced features like safe, electrolyzed water sanitation and additional cleansing modes for women.  It is a premium bidet that excites like the first time you’ve ever seen and used a bidet toilet in Japan.  And if your friends and family are like us, they’ll also be talking about it with excitement.  You can buy this product conveniently on Amazon.  Plus, depending on where you live, you can hire a handyman on Amazon to do the installation for you.
