Top complaints
TOTO Washlet S2 Electronic Bidet Toilet Seat
- 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.
Source: Wirecutter, CNN Underscored - Round seat still a bit small
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.
