PRODUCT DESCRIPTION
Now that the C5 has been discontinued, the NEW TOTO WASHLET S5 Electric Bidet Toilet Seat is available – A Smarter, Cleaner, More Comfortable Bathroom Experience. Instant Endless Warm Water, Slimmer Look and a Nightlight is just what the market was waiting for.
Upgrade your daily routine and bring modern comfort into your home with the TOTO WASHLET S5 Electric Bidet Toilet Seat. Designed for those who value hygiene, comfort, and innovation, the S5 offers a spa-like experience that makes every visit cleaner, easier, and more refreshing.
Whether you’re a busy professional, a parent, or simply someone who appreciates smart living, the TOTO Washlet S5 transforms your bathroom into a sanctuary of wellness and comfort.
Clean, Comfortable, and Completely Customizable
The WASHLET S5 provides instant warm water cleansing that’s far more soothing and effective than toilet paper. Choose from front, rear, and soft rear wash options, plus oscillating and pulsating spray modes for a custom clean every time.
Its sleek, low-profile design fits beautifully in any modern bathroom, upgrading your standard elongated toilet seat with advanced bidet technology.
Everyday Luxury with Built-In Smart Features
Enjoy the warmth of a heated seat with five adjustable temperature settings that keep you comfortable year-round. A built-in nightlight softly illuminates the bowl for safe use during the night—perfect for shared bathrooms or family homes.
When your cleansing cycle ends, the warm air dryer gently dries the area with adjustable temperatures. This feature minimizes the need for toilet paper, enhancing comfort while reducing waste.
Hands-Free Hygiene for Modern Living
TOTO’s advanced EWATER+® system automatically sanitizes the wand before and after each use, eliminating the need for chemical cleaners. The PREMIST® function lightly coats the toilet bowl before each use, helping waste wash away more easily and keeping the surface cleaner for longer.
These automated cleaning features make the S5 both a luxurious and practical addition for any household seeking improved hygiene with less maintenance.
Personalized Comfort for Every User
The slim, wireless remote control allows each family member to create their perfect experience. With four user memory settings, everyone can save preferred spray pressure, temperature, and nozzle position.
The SoftClose® lid and seat close quietly every time—ideal for light sleepers, families with children, or anyone who enjoys a calm, peaceful environment.

The ToTo Washlet exceeds expectations. Reasonably priced, delivered as promised, clear directions, installs easily, and works effortlessly.
This bidet has made regular toilets a disappointment. It was super easy to install too with clear instructions and a good manual that talks about how to clean it safely since electronics are involved. Cleaning is also really easy. If you’re someone who has IBS (which was our households motivator for purchasing it), it’s helpful for flare ups and making them less awful by allowing easier cleanup. A side note: the heated seat is something you quickly get used to that you’ll notice the absence of immediately if you then go use a normal toilet.
The only thing we would’ve changed is it probably would’ve been better to get an elongated bidet and switch out our toilet completely. If you’re a bigger person (even from just sheer size), the elongated would probably be better as the round seat is noticeably smaller than a normal toilet’s round toilet seat.
TOTO S5 Electronic Bidet Toilet Seat
Have really enjoyed my bidet ever since it was installed. Especially during the winter months.
Let customers speak for us
from 159 reviewsI love it.
Really good bidet, unlimited hot water and powerfull flow , I love it!
Seat is very comfortable and we use at least 50% less toilet paper.
Enjoying the seat very much.
To Toto bidet is great. Easy to follow instructions, and great service
My order was well packaged, delivered in a reasonable amount of time, and the price was right. I really needed a bidet that was not tankless because the power draw of a tankless model caused bathroom lights to flicker with every use :(. The smaller power demand of the model I purchased makes a big difference. Too bad TOTO has stopped making tankless models.
Our experience has been great. We were about to move to our new house and I ordered two sets of electric japanese bidets from EverFlowBidets because they offered the best deals and they had a very good reputation. I panicked when i unpacked the package and found that one piece (tank) was broken- seems that the shipper didnt handle the fragile package with enough care. I gave customer service a call and they were extremely understanding and helpful. I was able to get a new piece overnight and free of charge. Much appreciated!
I did a lot of research, settled on this one, and I’m glad I did. Had it about 6 months now- easy install, still tightly attached, no issues with operation at all. Delivered on time, too. Very happy with it!

Good delivery and working well
Our Toto KS6 was easy for me to install and provides all of the hoped for comfort and hygienic benefits. Toto remains the standard in washlets.
The company was a pleasure to work with. I wasn't sure I was buying the right product, so I dropped Customer Service an email. Imagine my surprise when the owner of the company called me to answer my question! I received my new bidet, though I'm waiting on an electrician to install an outlet in the bathroom so I can install the bidet. I'll update this review once the product is in. Will absolutely buy from this company again!
The transaction was smooth and customer service was beyond exceptional. Will be making another purchase again in the near future!
We haven’t installed it yet as this is a new build. No issues with receiving and package very well.
I have not had such good customer service, even in a face-to-face store. Already have my next order planned for when I do the other bathroom. Neal was an absolute delight to work with. Not just anyone, the owner of the company
