Best Smart Toilet (2026): 7 Bidet Toilets Compared

We may earn commission from links on this page. Lead-form submissions are forwarded to local inspector partners. How we research and review.

The best smart toilet combines the toilet and a full bidet seat in one unit: warm-water wash, heated seat, air dryer, automatic lid and flush. Unlike a bidet seat added to an existing toilet, an integrated smart toilet replaces the whole fixture, which means it has to fit your rough-in, work with your water pressure and plug into a safe outlet next to the toilet. Those three requirements, more than the feature list, decide which model works in your bathroom. Below are seven picks matched to specific homes, then a buying guide on rough-in, power, GFCI protection, water use and installation.

The seven picks, compared listing by listing

1. Onirap V12D — Best Overall Smart Toilet

Best overall

Why we like it

• Names both ETL and cUPC certification
• Built-in tank handles low water pressure
• 1.2 GPF, under the WaterSense threshold
• Stores settings for two users
• Child mode drops everything to lowest levels

Onirap V12D — 1.2 GPF, 1000g MaP, built-in tank, ETL + cUPC, IPX4 + leakage protection, 2-user memory, 12 in rough-in, 17 in ADA

One of Only Two Listings That Name Both an Electrical and a Plumbing Certification

A smart toilet is both a plumbing fixture and an electrical appliance, so it should carry a listing for each. Four of the 16 listings name cUPC, the plumbing certification, and only two also name ETL for electrical safety: this Onirap and the EPLO DP7 SE in pick 6. Most listings say nothing about electrical certification at all.

The Onirap also covers the two water problems that sink many smart toilet installs. Its built-in tank lets it flush at very low supply pressure, which matters in older homes and on well systems. Five of the 16 listings have a built-in tank or pump. It also has a built-in sediment filter you clean monthly. It is one of only two listings, with the Pudyavr in pick 5, that name both IPX4 water resistance and leakage protection.

At 1.2 GPF, it uses less water than the 1.28 GPF ceiling the EPA sets for WaterSense-labeled toilets. The listing does not claim the WaterSense label itself, and none of the 16 listings do. Its warranty is described as “after-sales support” rather than a defined warranty term, which is worth clarifying before buying.

2. EPLO U8MAX — Most Comfort Features

Most comfort features

Why we like it

• Dryer adjusts temperature, speed and position
• Auto-adjusts heat to room conditions
• Names cUPC, EGS, DOE and CEC compliance
• 17.41-inch ADA seat height

EPLO U8MAX — 1.6/1.1 GPF dual flush, 1000g MaP, built-in tank, moving dryer, ambient sensing, cUPC + EGS, 12 in rough-in

The Only Listing With a Moving Dryer and Ambient Temperature Sensing

Most smart toilets let you set dryer temperature. The U8MAX is the only listing that says its dryer also adjusts position and wind speed, and the only one with “four-season” sensing that adjusts seat, water and dryer heat to the room temperature automatically. In a Front Range bathroom that swings from a cold January morning to a warm July afternoon, that is a useful convenience.

The certification list is long: cUPC and EGS, plus compliance with DOE and CEC requirements. It also combines a built-in tank with a 1000g MaP flush score. At about 116 lb, it is the heaviest listing on the shelf that states a weight, which tells you something about the size of the tank and body, and it needs two people to set.

The trade-off is water. Its full flush is 1.6 GPF, the federal maximum, and the only full-flush figure above 1.28 GPF among the 16 listings. The 1.1 GPF half flush helps, but if water use is a priority, the Onirap or Pudyavr are better choices. No electrical certification such as ETL or UL is named.

3. DeerValley DV-1S0371-V3 — Best for Hard or Gritty Water

Best for hard or gritty water

Why we like it

• External filter for the bidet water
• Only listing naming UV-C cleaning
• Built-in tank and pump for low pressure
• Clear 2-year limited warranty

DeerValley DV-1S0371-V3 — 1000g MaP, tank + pump, external filter, UV-C, safety mode, 110V, 12 in rough-in, 2-yr limited warranty

The Only Listing Pairing an External Filter With UV-C Cleaning

Much of the Front Range has hard water, and smart toilet bidet nozzles and inline heaters are small passages that mineral scale can clog. Two of the 16 listings include filtration: the Onirap’s built-in sediment filter and the DeerValley’s external filter. The DeerValley is also the only listing that names UV-C cleaning. A filter does not soften water, but it does catch grit and sediment before they reach the bidet.

The built-in tank with pump assist means it does not depend on high supply pressure, and it is one of three listings with a child or safety mode, alongside Glendan and Onirap. It is also one of the few listings with a plainly stated warranty term: a 2-year limited warranty.

The listing leaves out the flush volume. It describes an ECO mode but never gives a GPF figure, which makes it hard to compare against the EPA’s 1.28 GPF WaterSense threshold. It also names no electrical or plumbing certification. Ask the seller for both before ordering.

4. Loniko U5 Tankless Smart Toilet — Best Tankless for Good Water Pressure

Best tankless for good pressure

Why we like it

• Only listing giving a psi operating range
• Dual flush at 0.92 or 1.28 GPF
• Four ways to flush
• Battery compartment for outage flushing

Loniko U5-1-WK — tankless, 0.92/1.28 GPF, 22–108 psi, radar lid, foot sensor, battery backup flush, 12 in rough-in

The Only Listing That States a Water Pressure Range in psi

Tankless smart toilets use supply pressure to flush, so they need enough of it. Eight of the 16 listings are tankless, and only the Loniko states the range it needs: 22 to 108 psi. That gives you something to check. A simple pressure gauge on a hose bib tells you in a minute whether your home qualifies. Most city homes on the Front Range fall inside that range; some foothills well systems and older homes do not.

The listing is also unusually candid about installation. It tells you to measure from the finished wall to the center of the floor drain, confirm space, make sure an outlet is nearby, and recommends a professional if plumbing or electrical changes are needed. Its dual flush tops out at 1.28 GPF, matching the EPA’s WaterSense ceiling.

Two caveats. Backup flushing during an outage works only if you have installed batteries, so put them in at setup. And the listing names no plumbing or electrical certification.

5. Pudyavr E5 — Best for Low Water Pressure

Best for low water pressure

Why we like it

• Built-in tank for low-pressure homes
• Lowest half-flush figure on the shelf
• IPX4 and leakage protection named
• Remembers settings after a power cut

Pudyavr E5 — tank type, 0.8/1.28 GPF, CEC test report, IPX4 + leakage protection, 110V, power-off memory, manual outage flush

The Lowest Stated Half-Flush Volume Among the 16 Listings

At 0.8 GPF, the E5’s light flush is the smallest figure on the shelf; the next lowest is 0.92 GPF, listed by three other models. Its full flush is 1.28 GPF, and the listing cites a CEC test report with a measured maximum flush of about 1.09 gallons. That is the most specific water-use evidence any listing here provides.

It is built for homes that struggle with tankless models: low-pressure houses, upper floors and rural properties on wells, which describes plenty of homes in the foothills and on the eastern plains. A built-in tank refills between flushes, so supply pressure matters less.

The listing says it meets U.S. electrical safety standards, but it does not name a testing lab mark such as ETL or UL, and it names no plumbing certification. It does name IPX4 and leakage protection, features shared only with the Onirap. No warranty term is stated.

6. EPLO DP7 SE — Best Smart Toilet Without an Auto-Open Lid

Best without auto-open lid

Why we like it

• ETL and cUPC both named
• Registered in the CEC database
• No auto lid that opens for pets
• Built-in backup battery for flushing

EPLO DP7 SE — tankless, auto + kick flush, no auto lid, ETL + cUPC, CEC registered, backup battery, 12 in rough-in, 17 in seat

The Only Listing That Advertises Leaving Out the Auto-Open Lid

An auto-open lid is a selling point for some buyers and a nuisance for others: it can open for a passing pet or child, and it is one more motor to fail. The DP7 SE is the only listing that says up front that it has no auto-open function. You still get auto flush when you stand, a foot-kick flush and a remote.

It is the other listing, besides the Onirap, that names both ETL and cUPC, and it adds that it meets CEC minimum efficiency standards and is registered in the CEC appliance database. For a buyer who cares more about certification than features, it is a strong option.

The listing does not give a GPF figure, which is odd given the CEC registration, and it is tankless, so check your water pressure first. No warranty term is stated.

7. HOROW HR-N30 Non-Electric Bidet Toilet — Best for Bathrooms With No Outlet

Best with no outlet

Why we like it

• No outlet or electrician needed
• Auto flush runs on 4 AA batteries
• 1.22 GPF, under the WaterSense threshold
• Wax ring, flange and T-valve included

HOROW HR-N30 — non-electric bidet, 4xAA auto flush, 1.22 GPF, 800g MaP, cool water, 12 in rough-in, 1-yr warranty

One of Two No-Outlet Bidet Toilets, and the Only One With Auto Flush

Many bathrooms, especially in homes built before the 1990s, have no outlet anywhere near the toilet. Adding one means an electrician, a GFCI-protected circuit and often patching drywall. Two HOROW listings skip the problem with non-electric bidets: this N30 and the T30. The N30 is the only one of the two with automatic flushing, powered by four AA batteries.

The trade-off is comfort. With no power there is no warm water, heated seat or dryer, only a cool-water wash from two nozzles. The 800g MaP score is lower than the 1000g scores on several electric models. If you want a 1000g MaP flush and the lowest single-flush volume on the shelf, the HOROW T30 offers 1.0 GPF but drops auto flush.

The included wax ring, flange and supply T-valve are a practical extra; most listings leave those to the buyer.

Before you buy: rough-in, power and water pressure

Rough-in

Rough-in is the distance from the finished wall to the center of the toilet’s floor drain. Every electric smart toilet here is designed for a standard 12-inch rough-in. Older homes sometimes have 10-inch or 14-inch rough-ins, and a 12-inch toilet will not fit those without plumbing work. Measure from the wall (not the baseboard) to the center of the closet bolts. Our toilet rough-in guide shows how.

An outlet next to the toilet

Electric smart toilets need a receptacle within reach of the power cord, usually on the wall behind or beside the toilet. Five listings tell buyers to confirm a nearby outlet before ordering, and a few say plainly that the toilet will not run its full features without one. Do not run the toilet from an extension cord. The U.S. Fire Administration advises never using an extension cord with a major appliance, and the NFPA notes that extension cords are intended for temporary use only.

Water pressure: tank or tankless

Eight listings are tankless and rely on supply pressure to flush; five have a built-in tank or pump. Homes with strong city pressure can use either. Low-pressure homes, upper floors and wells are better served by a tank-type model like the Onirap, Pudyavr or DeerValley. If you are unsure, test your pressure before you choose.

GFCI protection and electrical safety

Water and electricity are close together at a smart toilet, so the outlet that feeds it should be GFCI protected. The NFPA explains that ground-fault circuit interrupters reduce the risk of shock by cutting power when they detect a hazardous ground fault, and it says GFCIs should be installed by a licensed electrician inside the home in bathrooms, kitchens, garages and basements. It also recommends testing GFCIs monthly and choosing devices that carry the label of an independent testing laboratory.

Practical steps:

• Test the GFCI that protects the toilet outlet each month by pressing the test and reset buttons.
• If there is no outlet, have an electrician add a GFCI-protected receptacle. Our bathroom GFCI outlet guide explains requirements and common problems.
• Look for electrical certification on the toilet itself. Only two of the 16 listings here name ETL; none name UL. Ask the seller, and check the label on the unit.
• If the GFCI trips repeatedly when the toilet heats or flushes, stop using it and call an electrician; it may be a fault in the toilet or the circuit.

Water use: GPF, MaP and WaterSense

The EPA says toilets are the main source of water use in the home, at nearly 30 percent of an average home’s indoor water consumption. Its WaterSense program labels toilets that use 1.28 gallons per flush or less, which is 20 percent less than the federal standard of 1.6 GPF, and that are independently certified for both efficiency and flushing performance. The EPA estimates the average family can cut toilet water use by 20 to 60 percent by replacing old, inefficient toilets with WaterSense-labeled models.

None of the 16 listings on this shelf claim the WaterSense label. Most still state a full flush at or below 1.28 GPF, but only one, the EPLO U8MAX, lists a 1.6 GPF full flush. Several do not state GPF at all. MaP scores (800g to 1000g here) measure how much test media a toilet clears in one flush; 1000g is the top of the scale that most listings quote. Our best toilet roundup compares standard and WaterSense models if you would rather skip the electronics.

Installation: DIY or plumber?

Several listings say no plumber is required. Physically, a smart toilet installs like any one-piece toilet: shut off the supply, remove the old toilet, set a new wax ring, bolt the new unit and connect the supply. The differences are weight (84 to 116 lb on this shelf), the power connection and, for some, a separate bidet water line or filter. Our toilet installation guide walks through the job, and a failing toilet shut-off valve is worth replacing while the water is already off.

Call a plumber if the rough-in is not 12 inches, the flange is broken or below the finished floor, or the subfloor is soft. Call an electrician for any new outlet. If you only want the bidet functions, a seat or bidet attachment on your current toilet costs far less and needs no rough-in change.

Front Range notes

Hard water is common in much of the Front Range. Scale builds up in bidet nozzles, inline heaters and fill valves, so a model with a filter, or a whole-house softener, extends their life; clean the nozzle and filter on the schedule the manual gives. Cold bathrooms in winter make a heated seat and warm-water wash more than a luxury, and power outages during wind and snow storms are why backup or manual flushing matters. Ten of the 16 listings describe some way to flush during an outage.

When to call a professional

A smart toilet installation is a good time to check what is under the old one. Rocking toilets, stains around the base, a soft floor or a flange that sits low are signs of a past leak that may have damaged the subfloor. Our plumbing and water hub explains which pros handle what, from plumbers to water treatment specialists.
