A smart toilet can elevate your bathroom experience with innovative features such as heated seats, bidet features, self-cleaning technology, and automated flushing. But prior to purchasing one, there are several extrinsic factors that must be taken into consideration in order to have a hassle-free installation and seamless long-term performance.

Voltage & Outlet Specifications for Smart Toilets：

Voltage Specifications

Typical Household Voltage in the U.S.:110V – 120V

Outlet location limitations:

- As per NEC Section 406.9(C), outlet installations adjacent to a bathtub or shower are not permitted:

Outlets cannot be installed within 3 feet horizontally (about 0.9 meters) and 8 feet vertically (about 2.5 meters) in front of the edge of a bathtub or shower.

Exceptions:

For smart toilets or electronic toilets for private hygiene purposes, single outlets can be installed in one of the following positions:

Behind the toilet but not behind the tank.

On the wall opposite to the toilet from the bathtub or shower.

These exceptions are intended to offer assurance that the power connection of smart toilets is safe and code compliant.

Outlet height recommendations:

Although the NEC does not specify mandatory requirements for the installation height of outlets, industry practice generally recommends:

The outlet bottom is 12 to 18 inches (approximately 30 to 45 cm) off the ground. For intelligent toilets, the socket should be arranged in a convenient location for it to be accessed easily for insertion of the power cord, either behind or at the side of the toilet but not in immediate contact with water supply. Also, all bathroom sockets should be supplied with GFCI (ground fault circuit interrupter) protection in order to prevent electric shock accidents.

Measure Your Bathroom Space

Prior to choosing a bidet seat or smart toilet, measure the size of your current toilet configuration to guarantee proper fit.

Rough-In Measurement: The rough-in is the measurement from the wall to the floor drain of the toilet. Standard in the U.S. is 12 inches, but sometimes homes will have 10-inch or 14-inch rough-ins. Take your time measuring before buying.

Toilet Shape and Size: Smart toilets are available in various shapes, such as elongated and round bowls. Make sure the new one will fit comfortably in your bathroom without hindering cabinets or doors.

Bidet Seat Compatibility: When replacing your old toilet with a smart bidet seat, make sure to verify the shape and mounting hole distance for compatibility.

Water Supply Requirements

A smart toilet or bidet seat requires an available and consistent water supply.

Shut-Off Valve: Ensure your bathroom has a particular shut-off valve near the toilet.

T-Valve Adapter: If installing a bidet seat, check if you need a T-valve adapter to connect to your existing water supply.

Hose Length: Ensure the water supply hose is long enough to reach the point of connection.

Drainage and Plumbing Compatibility

Different toilets come with different drainage systems, hence the need to find a smart toilet that is compatible with your house's plumbing.

Floor Drain vs. Wall Drain: The majority of U.S. homes are equipped with a floor drain, but custom or older homes feature a wall drain system. Ensure your model selection will be compatible.

Waste Pipe Condition: When replacing an older toilet, check your waste pipe for blockages or damage that may hinder proper drainage.

Water Pressure Requirements and the Role of a Built-in Water Tank

The Complete Guide to Choosing a Smart Toilet

Intelligent toilets use water pressure for proper flushing and bidet operations.

Standard U.S. Water Pressure: Standard water pressure in the majority of residences ranges from 40 to 60 PSI (pounds per square inch).

Low Water Pressure Solutions:

If you live in a high-rise building or low-pressure zone, consider a model with a built-in booster pump for enhanced performance.

Integrated Water Tanks Smart Toilets are fitted with tanks to store water for flushing and bidet functions and are ideal for houses with low or fluctuating water pressure. The toilets give a constant, powerful flush regardless of the change in water supply.

Bathroom Space and Environment

Installation space for proper installation to allow for working and maintenance of the smart toilet.

Clearance Space: Provide ample space around the toilet for lid opening, use of the remote control, and comfort of the user.

Ventilation: Ventilated bathroom prevents excess moisture from damaging the electronic components of the toilet.

Smart Features: Choose top-end features like automated flushing, heated seats, self-cleaning nozzles, air drying, night lights, and smartphone control to enhance your experience.

Once you’ve determined the external requirements for your smart toilet, focus on selecting the features that best suit your needs.
