Wirecutter's top bidet seat: instant warm water, a quiet and comfortable spray, four user presets and an excellent remote. It costs about $150 more than the S2, has no backup controls on the seat if the remote is lost, and its deeper settings need the manual.

Top complaints

  • No controls on the seat

    Wirecutter says the S5 has no onboard buttons, so if the remote is damaged or dropped in the toilet, you can't use the bidet. One of its long-term testers switched to a side-panel model after kids dropped a remote, and replacements aren't cheap.

  • Pricey, and settings need the manual

    Wirecutter says the long-term settings on the remote are often baffling without the manual. CNN Underscored calls the price too high for anyone but the most bidet-obsessed.

  • Needs an outlet; plain plastic T fitting

    Like all electric seats, it needs a nearby outlet; Good Housekeeping cites about $300 to have one added. Wirecutter notes the T fitting is gray plastic rather than chrome; Toto says that is less likely to damage the tank threads. Amazon's small set of reviews calls installation mixed.

What owners love

  • Comfortable, quiet, customizable spray

    Wirecutter says the spray is quieter and more comfortable than most, with five pressure levels, five nozzle positions and oscillating or pulsing modes. Even the strongest setting stays comfortable.

  • Instant warm water and eco modes

    Wirecutter says the instant heater gives warm water for as long as you need it while using less energy. It has two eco modes, one of which learns your usage. Amazon owners appreciate the warm water and heated seat.

  • Best remote, four presets

    Wirecutter calls its remote the best it has tested, with everyday controls on the front and rarely used settings on the back. It has four user presets, two more than most other bidets Wirecutter recommends.

What experts say

  • Wirecutter (NYT): Top pick (updated 2026-09-08): the best bidet it has used, with no onboard controls and a confusing settings menu as its flaws.
  • CNN Underscored: Not picked: one of the best bidet experiences, but too pricey for most people next to the S2.
