Smart toilets have become a major talking point in home renovations over the past few years. Whether upgrading the main bathroom or building an en-suite, it is a piece of sanitary hardware that plays an integral role in the room’s aesthetic and function. One of the big questions on most homeowners’ lips, however, is simply: do Smart toilets need electricity?

On average, a bathroom renovation costs US homeowners around $16,500. A Smart toilet would be a noticeable investment, but is likely to account for significantly less than 10% of that budget. Still, it’s important to know what to expect from the sanitary hardware before potentially making a purchase.

The following guide will flush away any ambiguity.

Do Smart Toilets Need Electricity?

Standard toilets have been used inside some homes since the late 1800s and have been commonplace since the middle of the 20th century. Throughout the decades, their functions and features have largely remained unchanged. When you press the flush, water from a tank is released into the bowl, forcing water and waste to push over a curved pipe and be taken away through plumbing lines. The water tank then refills the cistern ready for the next flush.

However, home tech has evolved at a rapid pace in recent years. Smart technologies have emerged in virtually every room, and Smart toilets are one of the best to hit the bathroom. The plumbing elements are essentially the same as a standard toilet, but they additionally feature advanced features and automated functions that do require electricity.

Smart toilets in the US will be powered by a standard 120-volt AC power supply, which runs at 60 Hz and a 15-amp or 20-amp circuit. They should be connected to the main power supply via a standard socket and never utilize extension cords due to safety issues.

The electricity features must use a Ground Fault Circuit Interrupter (GFCI) outlet to prevent electric shocks. The power outlet should also be at least 152-305 mm from the floor and within 1219 mm of the toilet basin. If the home has stored solar energy through its roof panels, this can be used to power the toilet. Typically, Smart toilets found within residential environments use an estimated 0.5 to 1.5 kWh of electricity per day.

It should be noted that there are some very basic Smart toilet models that do not require electricity. However, their features are limited to bidet-style washing and pressure-assisted flushing.

The Key Features Of Smart Toilets

In truth, most Smart toilets on the market (at least models from the top manufacturers) share many of the same advanced features. Nevertheless, familiarizing yourself with the best technologies at work will make life a lot easier when comparing models.

The following table details the most significant elements requiring electricity:

Feature	Purpose
Bidet cleansing	To boost hygiene with rear and front washing. Users can customize pressure and temperature to suit their needs.
Automated flush	To add convenience and hygiene by creating a touchless solution for flushing your toilet.
Lid automation	Add further convenience and hygiene with a touchless solution for opening and closing the lid.
Heated seats	For added comfort during use and to help drying after using bidet cleansing, thus removing the need for paper waste.
Sensor lighting	To provide ambient lighting at nighttime, saving users from harsh room lighting.
Self-cleaning	To aid hygiene and reduce maintenance with built-in deodorizers and UV sanitization.
Power-outage flush	A backup battery power solution to support users when the home experiences temporary power loss.

You might not require a Smart toilet that boasts all of those features. But it is likely that you’ll want most of them.

Smart Toilet Dimensions & Installation Checklist

Understanding how the Smart toilet will look within your bathroom design is an important factor. While there is some variance between models, the dimensions typically fall into the ranges detailed below:

Feature	Dimensions
Length	610-813 mm
Width	381-457 mm
Height	457-711 mm
Clearance (Front)	610 mm or more
Clearance (Side)	381 mm or more
Rough-In Distance	305 mm (most common)

While the Smart toilet installation will be completed by an expert, you also need to understand the process. You must complete the following preparations;

Measure the available bathroom floorspace to confirm that the toilet will fit without causing movement restrictions.

Measure the rough-in to verify that the distance from the finished wall to the waste pipe aligns with the toilet specs.

Check that the water supply line is compatible and accessible for the intended installation of a Smart toilet.

Check that it is possible to add a GFCI-protected electrical outlet and, where applicable, connect to Wi-Fi.

Confirm that the floor is level and stable. Otherwise, it may not be able to support the toilet fixture.

Confirm that all doors and fixtures can function as usual without coming into contact with the toilet unit.

Our step-by-step guide will take you through the process of Smart toilet installations, covering the hardware itself as well as plumbing and electrical components. Nonetheless, calling a registered professional is the best option if you desire an aesthetically-pleasing, safe, and functional finish.
