The Features We Love in Smart Toilets

Eco-friendly Functionality

One of the first and most basic things you’ll find in smart toilets are features that conserve water to make them more eco-friendly. Here are the different types of eco-friendly toilets you will find while looking for a new toilet.

Low Flow Toilets - Most older toilets use 6 gallons of water per flush—a completely unnecessary amount! Low flow toilets only use 1.6 gallons of water per flush and are just as effective at removing human waste as older toilets. Low-flow toilets are so effective and eco-friendly that a law was enacted in 1994 to ensure that all toilets manufactured and installed after that year only use 1.6 gallons of water per flush.

Dual Flush Toilets - These toilets take eco-friendly a step further with two flushing options—one for liquid waste that uses .8 gallons of water and the other for solid waste that uses 1.6.

WaterSense Toilets - Similar to the EnergyStar ratings for electrical appliances, toilets can receive a WaterSense rating from the EPA. The WaterSense program sets higher standards for eco-friendliness, and manufacturers that meet the criteria can use the WaterSense label to promote their products. To qualify, the toilet must use at least 20% less water than the 1.6-gallon standard.

Toilets with Integrated Sinks - Though not as common as the other eco-friendly options listed above, some toilets save water by having a sink attached to the lid. Clean water is pumped through the faucet when you wash your hands and then is drained into the toilet bowl below to be used for flushing.

Composting Toilets - These toilets use no water at all—natural decomposition and evaporation remove human waste! These kinds of toilets are more common in rural areas than in cities because cities have stricter local ordinances about toilets. Before buying one of these, check to make sure it complies with local requirements.

The easier a toilet is to clean, the better! Some of the best intelligent toilets are ones with advanced, innovative self-cleaning technologies that ensure a more sanitary bathroom experience. Here’s a look at just some of these technologies:

Eco-friendly Electrolyzed Water - Toto developed and pioneered the use of eWater+, a type of electrolyzed water that acts as a safe, eco-friendly disinfectant that reduces stains, odors, and the need for harsh cleaning chemicals. Toto products with this innovative technology automatically mist the bowl with eWater+ after each toilet use or after 8 hours of unuse.

Premisting Premisting is another Toto smart toilet technology. Premisting coats the toilet bowl in moisture before use, making it easier for waste to slide off the surface.

UV Light Some smart toilets include a special UV light or other lighting technologies that can help disinfect and regularly clean your toilet bowl or bidet wands.

Ceramic Glaze Even the toilet’s material goes a long way in keeping it clean. Intelligent toilets often employ a unique glaze, like Toto’s CeFiONtect ceramic glaze, that makes it harder for waste to stick to the surface of the toilet bowl.

High-efficiency Flushing Not only can efficient flushing save you water, but it can also save you time cleaning. High-efficiency, powerful flushing technologies like Toto’s Tornado Flush or Kohler’s Revolution 360 Swirl Flushing can help reduce waste build-up and keep your toilet bowl cleaner, longer. Some Kohler smart toilets even come with a feature that sends out a special cleaning solution with each flush.

Automatic Flushing & Toilet Seat Opening/Closingonly are automatic flushing and lid opening/closing features convenient, but it’s also more sanitary. These touchless, motion-activated functions help keep your toilet more hygienic by eliminating high-touch areas like toilet lids and handles. Plus, you never have to worry about forgetting to flush!

seat warming

Seat warmers are no longer just for cars! Heated toilet seats are an innovative high-end feature for new toilets that are nice to have when you consider that the average person spends 3 hours a week taking care of business. Heated toilet seats can be found as a built-in feature of smart toilets, or you can buy a separate heated seat to replace the one you already have on your toilet.

seat lighting

Tired of stumbling in the dark in the middle of the night to use the bathroom? Maybe it’s time to add a nightlight to your toilet! Want lighting that coordinates with your bathroom’s aesthetic? There are options for that too! Many toilets with light features include multiple color and brightness settings plus auto shut-off features to conserve energy.

bidet control

Bidets are great for cutting down on toilet paper waste, are more hygienic than toilet paper, and are becoming increasingly common worldwide. We love having bidets integrated into your smart toilet, but you can also find more affordable options amongst bidet attachments, bidet toilet seats, and handheld bidets. Additionally, washlets—whether built-in to your toilet or bought separately—come with a whole slew of other smart toilet features:

Adjustable Water Pressure & Spraying - Smart washlets often come with various water settings, allowing you to adjust the spray’s water pressure or even change how it sprays. For example, some bidets come with pulsating or oscillating spray options.

Multiple Water Temperature Settings - Along with adjustable water pressure and spraying, some washlets offer multiple water temperature options to ensure maximum personalized comfort.

Warm Air Drying - Bidets may include an air-drying feature with multiple air temperature settings.

We all know that some trips to the bathroom are smellier than others, making built-in deodorizers a great addition to smart toilets!

Some smart toilets have built-in Bluetooth speakers so you can listen to music from your phone. Wifi capabilities enable you to use features like Amazon Alexa or adjust settings remotely.

The goal of a smart toilet isn’t to overcomplicate your life but to simplify it. Many smart toilets come with a remote or side panel where you can control the features manually. However, most of the intelligent toilet features we’ve mentioned, especially self-cleaning technologies, are automatic! That way, you don’t have to necessarily keep track of each feature that’s available to you—the toilet is smart enough to do it for you.

Smart Toilet Seats Are a Good Upgrade, Too!

Not ready to fully upgrade to a smart toilet? Smart toilet seats are an excellent way to go! You can find smart toilet seats that include things like bidets, heated seats, motion censored lids, and more! Browse affordable smart toilet seats and bidets.
