High-Tech Smart Flush Toilets Buying Guide

High-tech smart toilets are designed to elevate your bathroom and provide a touchless toileting experience. These toilets are the new home evolutions in the world of personal toilet care.

What is A Smart Flush Toilet?

A high-tech smart toilet comes with built-in innovative technologies that include an automated lid, heated seats, self-cleaning functions, customizable temperature and pressure settings, automated flushing, and automatic washing and drying options. These innovative technologies transform the way you use your toilet and elevate the value of your home. 

If you come across a smart toilet that doesn’t have the above features, skip it and keep shopping. Established toilet makers who include some of these features may not even classify their products as smart toilets. A toilet that looks and feels like a smart toilet but without the necessary features, such as a bidet system, is only designed to bridge the cost gap between intelligent water closets and high-end tank and bowl designs.

Here is an overview of some of the functionalities of the smart toilet features you should look out for when shopping for a high-tech smart toilet:

Seat Warming

Modern-day smart toilets come with seat warming capabilities. In fact, you can find a smart toilet with multiple heat settings that allow you to personalize the settings to your liking. 

Remote Controls and Apps

The remote control of an “intelligent toilet” almost resembles a car dashboard. This remote control capability virtually brings all the controls to your fingertips for easier and faster operation. A high-tech smart toilet comes with an LCD display that allows you to see the activations and adjustments of your toilet. 

So, you can use the remote control to change the pressure and temperature of your toilet’s spray wash whenever you want without too much difficulty. In addition, you can activate or deactivate other features such as automatic closing and opening of the seat, lighting, and auto-flushing.

Automatic Lid

A toilet with an automatic lid will sense when you approach and slowly open the lid; it also closes the lid quietly when you finish your business and exit the bathroom. This means that you don’t have to risk contaminating your hands by opening and closing the lid manually whenever you go to the bathroom.


A high-tech smart toilet mounted on your bathroom floor doesn’t rely on the force of gravity to flush effectively. A tankless toilet uses a valve and an electric pump to execute the flush. Meaning, the toilet uses water from the pipe to flush, not water stored in a tank. A computerized valve allows a preset amount of water to get into the toilet bowl when you initiate a flush. This means that you won’t have to deal with those disgusting leaks in your bathroom or even keep replacing broken flush valves.

Warm Water Wash

A toilet that is fitted with a bidet system is great for ensuring that you maintain your hygiene. Although this might not sound like the coolest feature of a smart toilet, it’s a great idea to some people. It gets even more comfortable when you can adjust the pressure of the warm water spray to suit your preference.

Side Control Panel

In case your remote control fails, you can still enjoy the features of a smart toilet by using the side control panel. The panel effectively operates the basic wash functions. That also means that the functions on the side panel of your smart toilet are not as comprehensive as the ones on the remote control.

Shape and Size

The construction of a smart toilet matters a lot, especially when you’re mindful of your bathroom layout and space. If the physical toilet size limits you on the type of model to purchase, you should choose a unit that is less than 27” long. The bowl of most high-tech smart toilets is broader and often longer than 28”. Typically, toilets with bigger bowls are usually more comfortable than those with compact bowls. However, high-end intelligent toilets have more helpful features, which are even more important than just the size of the bowl.

Air Dryer

With an air dryer, you may actually not need tissue paper. Moreover, this is one of the features that makes smart toilets eco-friendly.


This is a great inclusion into the list of smart toilet features, especially in homes with young children who often forget to flush the toilet. The feature ensures your toilet bowl remains clean at all times, even when you’re not at home.


This is a great feature as it lights the bathroom to ensure everyone is safe when going for night calls. Most of the LED nightlights on many brands are designed to illuminate the bathroom with soft glows to brighten bathrooms. The soft glow won’t force you to wake up fully when going for a short call at night.

The Cost of a Smart Toilet

The cost of a smart toilet depends on various factors, including where you make your purchase, the model, and the features that come with the unit. In general, the price ranges between $1,000 and $5,000, or even more. Since this is a solid bathroom fixture that you’ll use for several years to come, it’s not a bad idea to invest in a durable unit that will give you good value for your money. 

You can also opt to replace your current toilet with an electric bidet seat, especially if you’re working on a tight budget. Overall, focus on settling for the best option your budget can accommodate, not the cheapest available smart toilet. Some smart toilets come with a backup battery to allow you at least one flush when there is no power.
