Is The TOTO S550e Worth It?

Toto S550E is a model of the Toto S550E made by Toto which is a Japanese company established in 1917.

Toto is the world’s biggest toilet manufacturer. It is also known for creating the washlet.

Its Toto S550E is among Toto’s most well-known bidets.

Although it’s one of the most expensive bidets It’s also feature-rich, visually appealing, and has the durability and quality you’d think of from the Toto brand.

If you don’t care about price, Toto S550E is an ideal choice if you’re looking for the top of a line, reliable, constructed bidet with virtually every feature you could ever want.

Features of the Toto S550E

Toto S550E Toto S550E has all of the features you’d expect from an expensive bidet.

The sleek, modern style and the assurance of buying the bidet from the trusty Toto name make this top-of-the-line bidet worth the cost.

Automatic Open/Close Lid

If you’re a skeptic (or anyone who isn’t a fan of touching toilet lids) you’ll love the automatic shut and open lids of the Toto S550E. Toto S550E.

The cover of the model has a motion sensor that detects the presence of a person and then instantly is opened.

The lifting and lowering of the seat are as easy as pressing the button on the remote.

When you’ve finished and gone off, the lid shuts.

Wireless Remote

Similar to the majority of premium bidets like the Toto S550E is operated via wireless remote control.

But, the most notable feature of the remote control on this model is the capability to save your settings.

The settings of up to two preferred ones are saved which allows you to adjust water pressure and temperature.

Furthermore, it comes with a wall-mounted mount that eliminates the requirement to hold the remote. Instead, it is operated at the push of one button.

Heated Seat

The Toto S550E comes with heated seats as standard on bidets at this price point.

A lot of people love this feature, but If you aren’t a fan of the “just been sat on” sensation of heated toilet seats, the feature can be turned off.

Warm Air Dryer

If you’re environmentally conscious then the air dryer that is warm that has an adjustable temperature setting will let you remove the requirement for the use of toilet paper. There are other bidets equipped with dryers that are available on the market, and this feature alone does not make sense to pay for the extra cost me.

Warm Water

In contrast to other models with lower prices that feature a reservoir that is often bulky and holds hot water. The model has instantaneous, continuous heating of the water so you’ll never encounter the threat of an icy-cold blast of water that frightens your back.

Rear & Front Cleansing Streams

Pre-mist & E-Water Technology

The E-water technology produces electrolyzed water which transforms it into a strong and safe cleaning compound, and the pre-mist feature sprays your inside of the toilet with water prior to and after each use and helps keep it free of any buildup.

This is a wonderful option for those who may be concerned about whether bidets are safe and sanitary.

The only difference between the S550e and S500e models is that the S550e model has the night light as well as an automatic shut/open seat and lid. In addition to these two variations and the washlets are identical.

Summary – Toto Washlet S550E Review

Toto S550E is a luxury top-of-the-line bidet that comes with options.

The Toto washlet s550e reviewed brand is highly respected and trusted throughout the world of bidets and toilets.

It is the most effective bidet or washlet you can buy. It’s no surprise, it is the Japanese can be the most effective in washlets. I’ve even visited Japan. This is equipped with every feature you would want in an existing washlet added to a toilet that is already in use.

The only thing that’s missing when it’s been added to the existing toilet is that it won’t really flush the toilet for you while standing up. Check out the PreMist and EWater. Also, if you are able to stand still for 90 seconds at high temperatures, or even more at the lower temperature setting the dryer is one of the best available.

Other features, like closing and opening by themselves as well as the light for the night, have been my personal favorites. The washlet is located situated in my master bathroom, and the toilet is situated in an area that is completely by itself, so frequently I don’t have to need to think about the light even once.

I have the remote hanging on the wall, but thanks to the preset, I don’t take the time to remove it from the wall holder.

If you’re in search of an efficient, stylish, and reliable bidet with a large variety of features, and you’ve got a substantial budget the bidet is an excellent choice.
