What Makes a TOTO Japanese Toilet Different

What makes a TOTO Japanese toilet different is that the seat and the bowl are engineered as one product rather than bolted together afterwards. TOTO has built plumbing fixtures in Kitakyushu, Japan since May 1917, and in 1980 introduced WASHLET, which it describes as the world's first luxury toilet seat with electronic bidet functionality; its own timeline records 70 million WASHLET units sold worldwide by 2025. Every set on this page is that pairing.

Integrated Smart Toilet or WASHLET+?

Integrated TOTO smart toilets — NEOREST and G5A combine the toilet and electronic bidet system into one purpose-built fixture. These are the models most shoppers picture when they think of a high-end Japanese smart toilet.

WASHLET+ toilets — Pair a traditional TOTO toilet with a compatible WASHLET seat while hiding the cord and water connection through the bowl.

WASHLET is the seat. WASHLET+ is the pairing.

A plain WASHLET is a bidet seat that replaces the seat on a toilet you already own. A WASHLET+ set is what this collection sells: TOTO says WASHLET+ models seamlessly connect a high-performance TOTO toilet and a WASHLET+ bidet seat with no visible hoses or cords, because the bowl is built with a channel that hides the power cord and supply hose. To keep the toilet you have instead, the standalone TOTO WASHLET seats wash the same way.

The four WASHLET grades, and what actually separates them

All four grades share the same core: a heated seat, a warm air dryer, a deodorizer, a night light, PREMIST and EWATER+. What changes is control and range. The S2 is run from a side panel with three water and seat temperature settings. The S5 moves to a remote control, which is the only line TOTO's own comparison chart shows separating it from the S2. The S7 raises water and seat temperature to five settings each and adds the wide front cleanse. The S7A adds the touchless auto open and close lid on top of that. Every grade washes rear, soft rear and front, with oscillating and pulsating options.

What the bowl does on its own

Two of these technologies work on the china, not the electronics. TORNADO FLUSH uses two powerful nozzles that create a centrifugal, cyclonic rinsing action, on a hole-free rim that is easier to wipe down. CEFIONTECT is TOTO's glaze, described as extraordinarily smooth and formulated to stop particulates adhering to porous ceramic surfaces. The WASHLET adds two more: PREMIST wets the bowl before use, aiding the removal of waste, and EWATER+ electrolyzes water into hypochlorous acid to keep the wand and the bowl hygienic.

Are TOTO Japanese Toilets Worth the Money?

A TOTO Japanese toilet is worth the money if you want the bowl and the seat to match and you will use the wash daily; it is not if all you want is the wash. A WASHLET+ set always costs more than putting a bidet seat on the toilet you already own, and the difference buys the concealed cord and hose and a bowl designed around the seat.

How much is a Japanese Toto toilet?

Our smart toilet guide puts full units in the $1,000 to $5,000 or more range and bidet seats at $80 to $800. Most WASHLET+ sets here fall into bidet toilets from $1,000 to $2,000, with the S7 and S7A pairings moving up into luxury bidet toilets over $2,000.

Where the running costs go the other way

Two things pull the other way after purchase. Toilet paper use drops sharply once the wash and the dryer are doing the work, and our cost guide reports households cutting it by 75 percent or more. Water use is already low: most sets here flush at 1.28 gallons, the Aquia IV sets are dual flush at 1.28 and 0.9 gallons, and the 1G versions of the Nexus, UltraMax II, Carlyle II, Vespin II and Drake II run at 1.0 gallon per flush.

How to Choose the best Japanese TOTO Toilet

Choosing between the TOTO Japanese toilets on this page comes down to five decisions, and they are not equally weighted: rough-in, WASHLET grade, one-piece against two-piece against wall-hung, seat height, and finish. Rough-in goes first because it deletes whole series from your shortlist.

1. Measure your rough-in before you look at anything else

Rough-in is the distance from the finished wall to the center of the closet bolts at the base of the toilet, and TOTO builds to 10, 12 and 14 inches only. Twelve is the standard, but measure yours to the wall rather than the baseboard, and if you genuinely read 11 inches, order the 10-inch model. The series differ here. Aquia IV, Carlyle II, Vespin II, Legato, Aimes, Soiree, Guinevere and Carolina II reach 10 and 14 inches through TOTO's Unifit adapter, ordered with the toilet and fitted during installation. Nexus offers 12 and 14 inches only. Drake and Drake Transitional sell the 10-inch as a separate toilet, not an adapter. Drake II, UltraMax II, Connelly and Supreme II are 12-inch only. The series-by-series table is in our rough-in size guide, or start from the 10-inch rough-in smart toilets.

2. Pick the WASHLET grade, then the bowl

Pick the WASHLET grade before the bowl, because it drives the price and the daily experience more than the styling does. Most series here are offered with two or three grades, so once you have settled on the side-panel S2, the remote-controlled S5, the five-setting S7 or the auto-lid S7A, you can choose the bowl freely.

3. One-piece, two-piece or wall-hung

One-piece sets such as the UltraMax II, Legato, Carlyle II and Soiree have no seam between tank and bowl, which is one fewer place for grime to collect. Two-piece sets such as the Drake, Drake II and Vespin II arrive in two boxes, which matters if the bathroom is up a narrow staircase. Wall-hung sets like the EP, RP and AP mount on an in-wall carrier and have no floor rough-in at all, but the carrier has to go in before the wall is closed. Our one-piece versus two-piece comparison covers the trade-offs.

4. Standard height or Universal Height

Universal Height puts the seat about two inches higher than standard, roughly 17 to 19 inches instead of about 15, and within a series the bowl shape, flush and footprint are otherwise the same. TOTO encodes it in the model number: an F in the SKU means Universal Height, so two listings differing by one letter are the same toilet at two heights. Taller adults, older users and anyone who needs ADA seat height should take the Universal Height version.

5. Match the finish, including the seat

TOTO finishes carry a two-digit code at the end of the model number: Cotton White (#01), Colonial White (#11), Sedona Beige (#12) and Bone (#03). Cotton White is the default and often the only option on a given model. The catch on a WASHLET+ set is that most WASHLET seats are made in Cotton White and Sedona Beige, so a Colonial White bowl may have no exact seat match. Our TOTO white comparison shows how the codes behave in a real bathroom.

Frequently Asked Questions about Japanese Toto Toilets

What are the drawbacks of buying a Japanese TOTO toilet as one matched set?

The drawbacks of buying a Japanese TOTO toilet as one matched set are the fixed pairing and the dependence on power. The channel that hides the cord and supply hose is built into that particular bowl, so the bowl and the WASHLET grade are chosen together rather than swapped later. The wash, heated seat and dryer stop during an outage, and electronic parts can need specialist service rather than a generic repair.

Do WASHLET+ bowls flush as well as a plain TOTO toilet?

WASHLET+ bowls flush as well as any other TOTO toilet, because the flushing is done by the china rather than the seat. TORNADO FLUSH uses two nozzles to create a centrifugal, cyclonic rinsing action on a hole-free rim, and the CEFIONTECT glaze keeps waste from sticking. Most sets here flush at 1.28 gallons, the Aquia IV sets are dual flush at 1.28 and 0.9, and 1G versions run at 1.0.

How long does a WASHLET+ set last before the seat needs replacing?

A WASHLET+ set lasts in two stages, because the seat ages before the china does. Our smart toilet guide puts a smart toilet at 10 to 15 years or more with proper maintenance, while a bowl and tank are usually reckoned at fifteen to twenty-five years. On a WASHLET+ set the seat is the part that gets replaced, and it comes off without disturbing the bowl underneath.

Is the WASHLET seat covered by the same warranty as the bowl it is sold with?

The WASHLET seat is not always covered by the same warranty as the bowl it is sold with. TOTO publishes a one-year limited warranty from date of purchase on its china fixtures and on most WASHLET models, but the S7 and S7A carry a two-year limited residential warranty, dropping to one year in commercial installations. Both apply to the original purchaser, so keep the proof of purchase for the set.

Do you wipe when using a Japanese toilet?

You do not need to wipe when using a Japanese toilet, but you do need to dry. The WASHLET does the cleaning with warm water, so all that is left is drying — either a few squares of paper patted on, or the warm air dryer, which is fitted to every WASHLET grade in this collection. Most households keep paper in the room and use far less of it.

Where does the power cord go on a Japanese TOTO toilet?

The power cord on a Japanese TOTO toilet runs through a concealed channel built into the bowl, which is what the plus in WASHLET+ refers to: TOTO says these models connect the toilet and the bidet seat with no visible hoses or cords. The cord still has to reach a grounded, GFCI-protected outlet near the toilet, so check that one exists before ordering.

Does a Japanese TOTO toilet have to be a one-piece?

A Japanese TOTO toilet does not have to be a one-piece. WASHLET+ sets are built on one-piece bowls such as the UltraMax II, Legato, Carlyle II and Soiree, on two-piece bowls such as the Drake, Drake II and Vespin II, and on wall-hung bowls such as the EP, RP and AP. Two-piece sets arrive in two boxes, which helps if the bathroom is up a narrow staircase.
