CNN Underscored's best bidet seat and Wirecutter's runner-up: the most comfortable stream and dryer CNN has tested, plus endless instant warm water. It needs an outlet near the toilet, the side panel is busy, and the round version's seat is still on the small side.
Top complaints
- Needs an outlet near the toilet
Wirecutter notes electric seats require a nearby outlet. Good Housekeeping says that if one isn't there, an electrician costs about $300 on average, according to Angi. CNN Underscored runs an extension cord across its counter.
- Busy side panel, no remote or presets
Wirecutter calls the side panel intuitive but busy, with very small writing that may be hard to read for people with limited vision. It has no user presets. CNN wishes Toto sold a cheaper S2-level model with a remote.

CNN Underscored says the round S2 has more sitting area than the old C2 but still less than an elongated seat. Wirecutter says bidet seats in general shrink the opening to about the size of a round seat.

What owners love
- Most comfortable stream and dryer
CNN Underscored says it has the most comfortable stream of any bidet it has tested, by a good margin. Its dryer was also the most comfortable, blowing in the right spot. Oscillating and pulsating modes can run together for a thorough wash.
Source: CNN Underscored - Endless instant warm water
A coil heater warms water as it flows; CNN ran a warm wash for three minutes without any temperature drop. Wirecutter says the S2 keeps the S5's heated seat and instant warm water.
Source: CNN Underscored, Wirecutter - Quick install, good toilet integration
CNN installed it in about 10 minutes. Wirecutter rates its installation and overall integration with the toilet among the best in the category, and Amazon shoppers also praise easy installation.
