Specifications side by side

How the picks were chosen

We started with 98 toilets marked as smart in the catalog. We narrowed the list by requiring a built-in bidet (not just an add-on seat), and then compared specifications such as flush type, bowl shape, piece configuration, height, and wall-hung options. We also considered non-electric versions for bathrooms without an outlet. Prices are read live from the store at the time we wrote this guide, and we did not test any of the units. Our picks are based on the information provided by the seller or the manufacturer's published specifications.

Picking the right one for you

One-piece, two-piece, or wall hung?

One-piece toilets have a seamless tank and bowl, making them easier to clean and more compact. Two-piece toilets are more traditional and often simpler to install, but they have a visible tank joint that can collect dust. Wall-hung toilets mount to the wall with an in-wall tank, freeing up floor space and giving a modern, floating appearance. Wall-hung models usually require extra framing or a carrier system, so they are best for new construction or major remodels.

Flush efficiency and WaterSense

The US federal standard is 1.6 gallons per flush (GPF), but WaterSense labeled toilets use 1.28 GPF or less and still pass rigorous performance tests. Many of the toilets in this guide fall into that range, and dual-flush models offer an even lower reduced flush for liquid waste. Choosing a WaterSense model can cut toilet water use by 20 to 60 percent per flush, according to the EPA, saving thousands of gallons a year for your household.

Bidet features to consider

Integrated bidet toilets vary widely in what they offer. Look for a heated seat if you live in a cold climate or just prefer warm contact. Warm-water washing and a dryer are common on smart models, while a foam shield adds a layer of lubricant and odor control. Auto open/close lids, foot sensors, and automatic flushing reduce the need to touch the toilet, which is a major hygiene benefit. Decide which of these features matter most to you and verify they are listed in the specifications.

Power and installation

Most smart bidet toilets require a standard 120V electrical outlet near the toilet to power the heated seat, warm water, and electronic controls. If you do not have an outlet, you can choose a non-electric model that uses manual or battery-powered flushing, or you can plan to add an outlet during installation. Also check the rough-in distance (10, 12, or 14 inches) and whether the toilet is floor-mounted or wall-hung. These measurements determine whether the toilet will fit your bathroom's plumbing.

ADA and comfort height

ADA-compliant toilets typically have a seat height between 17 and 19 inches from the floor, which is easier for people with mobility issues to sit down and stand up. Many smart toilets are advertised as "chair height" or "comfort height" and are designed to meet ADA guidelines. If you are installing the toilet for an elderly family member or someone with a disability, check that the height is explicitly stated. Also consider the location of the flush controls, as they should be easy to reach from a seated position.

Questions

Do I need an electrical outlet for a bidet toilet?

Most integrated bidet toilets with heated seats, warm water, and electronic controls require a standard 120V outlet nearby. If you do not have one, you can install an outlet or choose a non-electric model that operates without power. Check the specifications of each model to see if it needs electricity.

What does a 1000g MaP flush score indicate?

The MaP (Maximum Performance) score indicates the number of grams of solid waste the toilet can flush completely. A score of 1000g means the toilet can flush a full load of that weight. Many smart bidet toilets in this guide advertise a 1000g MaP score.

Are bidet toilets worth the higher price compared to regular toilets?

Bidet toilets offer added hygiene, reduced toilet paper use, and features like heated seats and automatic flushing. While they cost more upfront, they can save money on paper and water utility bills over time. Consider your budget and the specific features you value most.

Can I install a bidet toilet myself?

Some models are designed for DIY installation, especially non-electric ones or those that fit a standard 12-inch rough-in. However, integrated toilets with complex wiring and wall-hung systems often require a professional plumber and electrician. Always check the manufacturer's instructions and local building codes.

What is the ideal rough-in distance for a smart toilet?

The rough-in distance is the measurement from the finished wall to the center of the toilet's waste outlet. It is commonly 10, 12, or 14 inches. You need to match this measurement to your existing plumbing. Most homes have 12 inches, but always measure your current toilet to be sure.
