Quick Note:  The TOTO S350e and TOTO S300e are identical, except that the S350e has an automatic opening/closing lid.  Besides that, the two models are exactly the same.

The new TOTO S350e Washlet is TOTO's latest bidet seat and features a completely all-new design.  At just 4" in height at its tallest point in the rear, this is the world's thinnest electronic bidet toilet seat.  Yet it still carries over all of the main features and functions you would expect in a premium bidet toilet seat.  Equipped with both posterior and feminine wash features - water temperature, water pressure, and the position of the spray can all be adjusted with the handy wireless remote control.  Speaking of which, the remote control has been totally redesigned too.  It is now rectangular shaped (so it fits nicely in one hand like a TV remote) and has been upgraded to include two user presets.  The user presets allow you to pre-program wash settings (e.g., water temperature, pressure, spray position) right into the remote.

Some of the other new features you'll find is a pre-misting feature which pre-mists the toilet bowl with water before use.  This make flushing more efficient and effective compared to flushing a dry bowl.  The use of innovative eWater Technology is another great addition.  This feature mists your toilet bowl with electrolyzed water which keeps the bowl cleaner and helps reduce the need for harsh chemical cleaners.  There's also a new LED night light - very handy when using the restroom in the middle of the night.

Other features include an automatic opening and closing lid.  A heated toilet seat, warm air dry, occupied seat sensor, automatic air deodorizer, and power saving mode rounds out the rest of the main features of this TOTO Washlet.

Available in Cotton White and Sedona Beige.

Our official review of this seatbidetsPLUS' TOTO S350e Review


TOTO Models At-A-Glance:

Model Controls Key Feature Differences Accompanying Perks Just to Nitpick
TOTO S350e Remote Control Exactly the same seat at the TOTO S300e but comes with an automatic open/close seat and lid Happy wives don't have to tell their husbands to put the seat down anymore One year warranty is a bit short.  Other manufacturer warranties are longer
TOTO S300e Remote Control High-end TOTO model includes everything you would expect - tankless (on-demand) heating, night light, warm air dry, heated toilet seat Electrolyzed e-water mists the sides of the toilet bowl which helps minimize toilet bowl cleaning We anticipate next-generation models will include stainless steel nozzles.  But that won't be for a while
TOTO C200 Attached Panel C200 has a reservoir tank-type heater instead of tankless (on-demand) heater found on S350e/S300e Great price for a TOTO A bit bulky.  Almost twice the height of the premium models


New to TOTO?  A Brief Q & A:

Question Answer
What is the TOTO S350e? The TOTO S350e is an electronic toilet seat that provides a warm water wash after using the restroom.  TOTO actually trademarked the term "washlet" to describe their products but they are also commonly referred to as bidet seats or bidet toilet seats as well.
When was it released? The TOTO S350e was released in Fall 2012.  It is TOTO's flagship model, replacing its predecessor the S300.  Notable upgrades include a new thinner design that is just 4" tall.  The addition of e-water (electrolyzed water) mists the sides of the toilet bowl which helps minimize toilet bowl scrubbing.
Where is the washlet made? The TOTO S350e is made in Malaysia.  Being a Japanese company, many customers assume everything TOTO makes is made in Japan.  But there were cost efficiencies in opening a manufacturing plant in Malaysia, and TOTO decided the washlet units would be made there.
Why would this model be a good choice? The TOTO S350e looks fantastic.  At 4" tall, it is the slimmest electronic bidet seat in the world.  If aesthetics are paramount, the S350e would be a good choice.  Also performs quite nicely.  It's a fine-tuned machine, as TOTO has been in the game a long time.


TOTO Product Naming Conventions:

TOTO uses internal product SKUs which differ from the branded product name.  For example, you may have heard the TOTO S350e referred to as the TOTO SW584#01.  For your convenience, here is a mapping table to understand TOTO's naming conventions:

  Model SKU Color SKU Completed SKU
S350e Elongated Seat / Cotton White SW584 #01 TOTO SW584#01
S350e Round Seat / Cotton White SW583 #01 TOTO SW583#01
S350e Elongated Seat / Sedona Beige SW584 #12 TOTO SW584#12

Warranty Information

Q: What are the differences between the TOTO S350e and the S300e?

A: These two models from TOTO are hard to tell apart by looking at them, and that’s because they have the same body construction. They even have all of the same features except for one important difference: The S350e has an automatic opening and closing lid feature not available on the 300e. You can also raise and lower the seat of the S350e by pressing a button on the remote control.

Q: How does the e-water feature work?

A: The e-water technology on the TOTO S350e and S300e is an added feature to help keep the bowl of the toilet clean. It works by spraying a pre-mist of water onto the sides of the bowl to help prevent material from adhering to the surface. When you're finished, the unit sprays another mist with electrolyzed water which acts as a disinfectant. The e-water feature is designed to reduce the amount of harsh cleaning chemicals needed to clean your toilet.

Q: How does the automatic lid feature work?

A: As mentioned before, the TOTO S350e includes an automatic opening and closing lid. A body sensor on the unit detects whenever you approach the toilet and will automatically raise the lid when you're within a couple of feet of the unit. After use, the lid will close 90 seconds after you have left the area of the sensor. If you wish to raise the seat without doing so manually, you can press the button on the remote to raise the seat after the lid has been raised.

Q: What is the height of the TOTO S350e/S300e?

A: The body of the TOTO S350e and S300e has the narrowest profile out of all our electronic bidets. The height of the bidet at its highest point is 4” compared to other models that are between around 5.5” to 7” at their tallest point.

  1. You Need This

    Posted by Zephcom on 20th Jan 2017

    Okay, you likely don't need -this- unit. But a bidet...yeah, you need one. After 69 years of dealing with this issue the old fashioned way, I knew there had to be a better way. I knew the bidet was that way but always thought it meant a separate appliance and American homes are not designed for that separate appliance. The bidet seat fixes that.

    We chose the TOTO S350e because I've long known that one should always buy a better product than one needs for the job because the better product will make the job easier. The TOTO does just that. It wets down the sides of the toilet before use, it warms the toilet seat, it filters the air, it raises and lowers the lid -and- the seat as well as performing the service we bought the seat to do.

    Installation was as simple as the videos show. All the parts are included. It took less than an hour to open the package, look at everything, read the instructions and install it. A quick note for people who haven't done this type of thing before: Not all shut-off valves will completely stop the water so one should be prepared to make the plumbing changes while water is dripping out of the hose. And when attaching the tee fitting to the bottom of the tank, it is possible to twist the internal pieces inside the tank out of alignment. Having someone hold them when tightening the Tee to the tank might be advisable.

    We used an extension cord to get to the electricity. Now that we know we will be using the unit long term, we will be getting an outlet installed next to the toilet.

    We love the unit. About the only thing it doesn't do is flush the toilet. Buy it if you can afford it. If you can't afford it, buy a seat that performs the basic services because a bidet is truly a MUCH better solution than buying rolls of toilet paper.

  2. Great product, BUT

    Posted by Amanda N on 7th Sep 2016

    I have been using mine for 3 months now, and it is wonderful. BUT for the price, I think they should have made the ENERGY SAVER function a bit more robust. FIRST, setting it up is confusing and limited, needs to be more like the thermostats, with a time, weekly, and multi programs per day options.

  3. Excellent Bidet by TOTO

    Posted by Harvey on 15th Mar 2016

    Purchased the TOTO S350e washlet after I experienced use of various washlets during a visit to Japan. The S350e in my opinion works as well as the much higher priced integrated units. Installation was simple and the operating manual has clear descriptions of all functions.

  4. Esthetic!

    Posted by June Williams on 22nd Nov 2015

    The washlet s350e exceeded my expectations! I am so pleased! I have to go numerous times during the night and the automatic features make it much easier. I highly recommend this product.

  5. Drying fan broke after a year and a half

    Posted by Derek on 8th Jun 2015

    I love this bidet, and it has done us most well for the last year and a half. But yesterday the drying fan suddenly stopped working. I was very disappointed to find out that TOTO's warranty was only 1 year and that I would have to pay for shipping and repairs to mail it to their repair place in Ontario, California as well as live without a bidet for however long that could take. If the product was built to last longer, or the part was self serviceable I would definitely give it 5 stars.

  6. A Must Have!

    Posted by Mimoza on 26th Aug 2014

    I come from Europe and I am used to it. We have separate bidets there so you have to transfer to the bidet after the toilet. The TOTO S350e is even better. It does everything for you, you just touch the remote control and the rest is fabulous.
    It is very easy to install, you really do not need a professional. It is a beauty and luxury at the same time. The best decision we have ever made.

  7. I am in love with my toto 350e

    Posted by Emily on 12th Aug 2014

    I can't imagine not having one of these amazing bidets. Not only do I have one for my bathroom but I have another in my guests bathroom for my family and friends. Yes, I own two. They are thrilled when they see it and in love after the use it. Beautifully made and discreet in size. Yes it's a beautiful thing!

  8. Used a bidet in Japan and was hooked!

    Posted by Jackie on 28th Jul 2014

    I purchased the Toto S350e bidet. A friend installed the unit for me. I have invited my friends to come and try it. I don't know why I didn't get one sooner. I like the warm seat and the warm water that is used. You can even change the temperature if you like. I also like the idea that the lid opens when you stand in front of the toilet. A remote control is included to change position, water pressure, temperature and you can actually program it for two different people. There is an energy saver program you can use. What more can you ask for. You will not be sorry if you purchase one.

  9. Bidet review--350e

    Posted by Andy on 26th May 2014

    Very nice product. My only complaint is the drying cycle takes a long time. If fan were stronger it would be perfect.

  10. the best!

    Posted by Celine on 1st Jan 2014

    Wanting a bidet for years, I finally made the plunge! ;))
    So refreshing, so luxurious.
    Had a plumber install the unit. Went smoothly and at a reasonable price.
    I encourage the purchase of this unit. Europeans use bidets as a matter of course. They've been around a bit longer than us and just may know a few things. It's a very reasonable and fab luxury. And this unit is THE BEST.
