The TOTO T40 WASHLET+ and Auto Flush Ready S550e Elongated Bidet Toilet Seat with EWATER+ and Auto Open and Close Classic Lid is an electronic luxury seat that cleanses you with warm water, providing an exceptionally clean feeling. Instead of traditional toilet paper that can sometimes be rough and often ineffective, the WASHLET quickly provides comfortable warm water cleansing at the touch of a button. The TOTO T40 WASHLET+ Ready WASHLET S550e is designed to conceal the WASHLET bidet seat's power cord and water supply hose for a seamless installation. The WASHLET features TOTO's technologically advanced EWATER+ system that mists the wand and toilet bowl, reducing the need for harsh cleaning chemicals. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. Separatley sold Auto Flush kit provides a hands-free automatic flush after every use. No need to touch buttons or handles, and never worry about someone forgetting to flush. The TOTO WASHLET S550e is operated by a luxury style illuminated touch pad remote with 2 user memory to save preferred settings. The WASHLET features 5 spray settings, auto open and close lid, heated seat, a nightlight, and instantaneous water heating. The newly redesigned lid style resides flush with the toilet bowl, providing a streamline look and giving the impression of an integrated system. The WASHLET reduces the need for toilet paper, saving trees and water used to manufacture each roll. Medical conditions, age, and debilitating illnesses can make using the bathroom without assistance almost impossible; but with a WASHLET, just the touch of a button can leave you feeling clean. Includes mounting and connection hardware. WASHLET+ ready WASHLET models are designed to work with TOTO T40 WASHLET+ ready toilets only. If you are looking for a WASHLET bidet seat to fit your existing toilet installation, please look for WASHLET models that do not contain WASHLET+ in the description.

TOTO SW3054AT40#01 – Frequently Asked Questions

1) Will the TOTO S550e SW3054AT40#01 fit my existing toilet?
No, and this is the single most common ordering mistake with it. The SW3054AT40#01 is a WASHLET+ model, built to pair only with a TOTO T40 WASHLET+ ready toilet, where the toilet itself hides the water supply hose and power cord. Drop it on a standard elongated bowl and you have no concealment path for either connection. If you're retrofitting a toilet you already own, you want a WASHLET seat without "WASHLET+" in the model description.
2) What electrical do I need to rough in for a TOTO WASHLET S550e?
Standard 120 volt, 60 Hz power. The cord is 3.94 feet long, so the receptacle has to land within about four feet of the seat's connection point behind the bowl, which is why the outlet gets placed low and behind the fixture on a WASHLET+ rough-in. Plan the receptacle before the finish wall closes up; there's no battery fallback on an electronic seat like this.
3) Does the S550e bidet seat come with the auto flush kit?
No. The SW3054AT40#01 is auto flush ready, meaning the electronics are there for hands-free flushing, but the Auto Flush kit is a separate purchase. Order it alongside if touchless flushing is part of the spec, otherwise the toilet still flushes by its normal handle or button.
4) Is there a wall control, or is the TOTO S550e remote only?
Remote only. The S550e is run from an illuminated touchpad remote with two user memory positions, so two people can each store spray position, pressure and temperature. There are no controls on a side panel of the seat, which matters for a hospitality or multi-family install where a remote can walk off; budget for keeping the remote with the room.
5) Does the TOTO S550e run out of warm water partway through?
No. It uses instantaneous water heating rather than a small holding tank, so warm water is generated on demand and doesn't fall off during a longer cleanse or between back-to-back users. Water temperature is adjustable, as is the seat heat.
6) How do you clean under a TOTO S550e washlet seat?
The seat is quick release, so it lifts off the mounting plate for cleaning around the bowl rim and hinge area, then drops back on. That's the feature that makes an electronic seat workable for a housekeeping crew on a schedule. EWATER+ handles the wand and bowl misting on its own, and PREMIST wets the bowl before each use so less residue sticks.
7) Is the TOTO S550e washlet UL listed for a commercial washroom?
It carries ASME and UL certifications. Those are the two an inspector or a facilities spec typically calls for on a powered plumbing fixture: ASME on the plumbing side, UL on the 120 volt electrical side.
8) Does the S550e washlet include the mounting and water connection hardware?
Yes, mounting and connection hardware ships with the seat. What isn't in the box is the Auto Flush kit and the T40 WASHLET+ toilet itself, which the seat depends on to conceal the supply hose and cord.
9) What features does the S550e have that a basic bidet seat doesn't?
Beyond front and rear warm water cleansing with five spray settings, the S550e adds an auto open and close lid, a warm air dryer, an air purifier, a night light, a heated seat, and EWATER+ electrolyzed water misting of both the wand and the bowl. The lid on this version is the classic style that sits flush with the bowl for an integrated look. A simpler washlet gives you the cleansing and the heated seat and stops there.
10) Is the auto open and close lid on the TOTO S550e going to hold up to heavy traffic?
The lid and seat are plastic and motor driven, opening and closing automatically on approach. For a residential or light commercial washroom that's the intended duty. In a high-traffic public restroom where lids get sat on, forced, or leaned against, a motorized lid is a wear point a manual seat doesn't have; the quick release makes swapping the seat straightforward if you do standardize on it across a property.
11) What color does the TOTO SW3054AT40#01 come in?
Cotton White, TOTO's #01 finish code, is the only option on this model. If you're matching it to a T40 WASHLET+ toilet already in the building, specify the toilet in Cotton White as well so the seat and bowl read as one piece, which is the point of the flush classic lid.
