Auto Flush Toilets & Bidet Seats

Once you've lived with a toilet that clears itself, reaching back for a flush handle starts to feel like winding down a car window. An automatic toilet uses a sensor to tell when you've finished, so nobody touches the one surface everyone would rather avoid, which is a real step up for bathroom hygiene, and the bowl gets cleared even when a child or a distracted guest forgets.

Retrofit flushers that attach to an ordinary tank are a different product. This collection is about automatic flushing designed into the toilet itself, plus the WASHLET+ bowls and TOTO kits that add the feature to matching pairs, many of which we sell together as toilet with bidet combo sets so everything works as one system. If you're unsure whether your setup can take it, ask before ordering and we'll check compatibility with you.

How the Auto Flush Setups Compare

Best Auto Flush Toilets for...

Upgrading a TOTO WASHLET+ Toilet

The best auto flush upgrade for a WASHLET+ toilet is TOTO's own kit. The TOTO THU855 Auto Flush Kit fits T40 dual flush WASHLET+ bowls, works with S7 and S7A seats and is designed as an easy-to-install add-on.

Low Water Pressure Homes

The best automatic toilet for older plumbing brings its own power. The HOROW X70 stores and pressurizes water in a built-in tank and pump, for a strong, reliable flush whatever your home's water pressure.

Design-Led Bathrooms

The best auto flush toilet for a design-focused bathroom keeps its technology out of sight. The TOTO Neorest RS pairs soft, rounded lines with an automatic lid and auto flush in a modern one-piece design.

All-in-One Simplicity

The best automatic toilet for buyers who'd rather not pair parts is a single integrated unit. The TOTO WASHLET G5A combines the bowl, a heated bidet seat, an auto open lid and automatic flushing in one fixture, with no separate products to pair.
