4 Basic Tips For Choosing A Smart Toilet.
Find The Best Solution For You

Technology is designed to provide us with convenience and comfort. All areas of our lives are improving every day. Our wristwatches count our pulse, our phones report steps taken and calories burned, our cars park themselves, and lights have long since been switched on by sensing our presence.

And what about the inner sanctum of our homes, the restroom? Just like years ago, the lid falls with a bang. We still search for the toilet by touch at night. Like a hundred years ago, we reach for the toilet paper and are horrified if we forget to buy it.

We are stuck in the Stone Age! While we send orders from home for our car to warm up in the winter simply by pressing a button on the key fob, our own toilet seat remains as cold as ice. And what to say about the germs that are waiting for us on the lid and rim of the toilet bowl.
But do not despair. After all, even here, technology is not standing still. Along with smart phones, watches and cars, there is now a smart toilet. Try it once and you won’t want to live without it again.

Have you ever watched a movie, where a house was equipped with an artificial intelligence and with a course of time it went bananas? Some people say that the further, we go with all the technologies, the more danger they can pose. But today it isn’t the issue we are going to discuss. Technologies aren’t our enemy, at least right now, they make our lives much easier. There is a smartphone in every pocket, people constantly use smartwatches, even cars are smart right now, and they can drive automatically getting you away from the chase. So it’s no wonder that we got the best smart toilet as well. This device was made to keep us clean and dry.

The first smart toilet seat was created by the Japanese company TOTO. Japanese bought the patent from Americans at the beginning of the 80th. The research was incredibly vast: it was necessary to find out the most comfortable water pressure, the temperature of the water and seat, the best form of the seat, and so on. The slogan was pretty simple: “Your butt wants to be washed too”.

Long after this outbreak appeared a wide range of other companies in the market, such as woodbridge toilet, or brondell swash. The last one came up with the idea in Tokyo, where was a huge number of bidet toilet seats everywhere, but the instruction was not clear enough for foreigners. The person got wet crotch and inspiration.
Nowadays it’s almost impossible to tell which one of the best smart toilet is really the best, but we’ll try to figure it out.


TOTO SW3054#12 S550E. Electronic Bidet Toilet Seat

Since childhood, people are taught to wash hands after a water closet, and usually, people forget to wash hands before it also. And even if you do remember about cleaning, just imagine the number of bacteria that end up on your hands while you open the door or the lid! TOTO has solved this problem: the bidet toilet seat opens and closes absolutely automatically. There is a sensor that identifies when a person approaches or departs.
Due to the inbuilt system Ewater+, the bowl and toto toilet handle are cleaned without harsh chemicals before and after usage via electrolyzed water. It means that without using chemicals and cleaning agents, the toto faucets are cleaned automatically, reducing the amount of time you should spend on cleaning. 

  •  There are 5 spray settings, and they will clean you for as long as you need with the warm water stream. The cleansing is gentle, and the stream oscillates and pulsates for getting to all of the parts. The electronic bidet is created in two colors: Sedona Beige and Cotton White. The difference between them is not that big. Both of them provide you with remote control, and it may come in very handy.
What about installation, here you won’t need any additional help and you will easily do it yourself.

And the last but not least, air deodorizer, which will destroy any undesirable evidence of your visit. Due to all the features and characteristics it’s one of the best smart toilet.

  • User memory settings for quick access
  • Premist system- one of the finest cleanovations, the thin water layer that prevents from sticking any waste or whatsoever
  • Instantaneous tankless water heat- you don’t have to wait anymore.
  • Randomly sprays during the evening (additional cleansing process)
  • It’s easy to forget where you place the remote control. And it’s also easy to drop or break it.
Additional questions:
  • Does it support a wifi connection? It could help with troubleshooting and energy management

It does a lot, almost everything you can expect from a toilet seat, but it does not have a wifi connection.

  • Can it be used on any toilet, is it universal?

Yes, it will fit most toilets, but pay attention to the shape.

  • How does it make electrolyzed water without any added salt (or vinegar to control ph)? Would not the resulting “ewater” be extremely weak?

EWATER+ is generated from the common chemicals in the tap water. It is strong enough to help prevent the built up of organics, but still gentle and weak compared to a typical bathroom cleanser.

  • Does this flush the toilet?

Some TOTO WASHLET+ models feature auto flush technology. This is a standard style WASHLET and it will not have that feature.
