Description

The TOTO WASHLET S5 Round Electric Bidet Toilet Seat with Instanatneous Water Heating and PREMIST delivers ecology-minded luxury with a streamlined design. Unlike traditional toilet paper that can often be rough and ineffective, the WASHLET quickly provides endless comfortable warm water cleansing at the touch of a button. Part of the newly redesigned S series, the WASHLET S5 is fully automated, featuring an illuminating night light and a soft rear spray, rear cleanse, and front cleanse with the option of an oscillating or pulsating stream. The controls are located on a slim, wireless remote. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The S5 model utilizes TOTO's EWATER+ system when the wand self- cleans. EWATER+ transforms the water into a safe and powerful compound, creating peace of mind by cleaning the inside and outside of the wand before and after every use. The S5 WASHLET features a heated SoftClose seat with five temperature settings, an air deodorizer, and a warm air dryer with five temperature settings. Using a WASHLET reduces the need for toilet paper, saving trees and water used to manufacture each roll. As we get older, reduced mobility, medical conditions, and debilitating illnesses can make it increasingly hard to clean ourselves after using the toilet. With a WASHLET, just the touch of a button can leave you feeling clean and refreshed. Easy to install and includes mounting and connection hardware.

Outstanding Product!
Color: Cotton White Size: Round Style: Contemporary Lid
Outstanding performance and quality product. Straight forward installation but one must able to work low around a toilet. Seniors might find it a bit challenging to install. It’s an extremely well made and perfectly operating bidet with excellent features that work. A+++

Flawless operation and fit.
Color: Cotton White Size: Round Style: Contemporary Lid
This is an excellent design that clearly fits a lot of toilet makes. I installed mine and moved down an extra electric ground fault outlet. The system works flawlessly.

I had no idea how much I would love this!
Color: Cotton White Size: Round Style: Contemporary Lid
Wow! It’s almost impossible for me to find words to describe how wonderful this product is. I purchased it based on a recommendation of NYT Wirecutter, and I must say that it lives up to the hype. My existing toilet and seat were not at chair level, which was causing difficulty for a member of the household. I replaced the toilet with a chair-height model, and splurged on this seat. Note that the seat raises the height of the toilet more than a traditional, American style toilet seat would. That is not an issue in this household. I had no idea how much I would appreciate a heated seat, but in this extra cold winter that we are experiencing, it is a delight in the middle of the night! I also appreciate being able to adjust the water direction, more forward or back, and with stronger or lesser water pressure. And the tankless water heater means that I am never shocked with cold water. A feature I particularly love is the remote control. Many of the bidet seats have controls on a panel that comes off the side of the seat. Having the remote control in an easily reachable place is far more convenient, in my opinion. The basic operation of the remote is simple; however, keep the user manual handy. If you want to change the default settings, or make personal presets. The combination of buttons that you need to push is not intuitive. Fortunately, you will not need to make the changes frequently, once you have established your defaults and presets. ... show more

Great seat
Color: Cotton White Size: Round Style: Contemporary Lid
This unit does it all! Directions are not the most complete or clear, almost as if they are generic for all models. I still can’t figure out how to set the individual preferences which is why I gave 4 instead of 5 stars

Fits elongated American Standard nearly perfectly. Slight noise from fan, only of concern if bathroom real close and you have good hearing. Lots of features.

Heat!
Color: Cotton White Size: Round Style: Contemporary Lid
Works exactly as advertised. Love having warm water and a warm seat. The other bathroom does not have those features and it is a NOTICEABLE luxury on this model!

Great bidet for a round toilet seat ( 16.5)
Color: Cotton White Size: Round Style: Contemporary Lid
It really works and fits well if you have a round (16.5 inches) toilet seat. There is also a elongated toilet seat version but this specific model is for a round toilet seat.
