Toto Washlet S2

4.8(5 reviews)

TOTO's entry-level Washlet, introduced in summer 2025 as the direct replacement for the discontinued C2. The big change: the C2's water tank is gone — the S2 heats on demand so warm water never runs out — and the body is 19% slimmer. You keep the heated seat, PREMIST bowl spray, EWATER+ wand sanitizing, deodorizer, and warm-air dryer, and gain a night light, all run from a side arm panel at a ~$350 home-center street price.

Pros

  • Instant heating fixes the old C2's biggest complaint — that tank ran lukewarm after roughly 35-45 seconds and the second user in a shared bathroom got cold water; the S2 stays warm indefinitely
  • At $348 street (Home Depot) it's the cheapest ticket into TOTO's EWATER+ system, which sanitizes the wand with electrolyzed water before and after every wash — rivals at this price rinse the nozzle with plain water
  • PREMIST wets the bowl before you sit, which measurably reduces waste sticking — owners report scrubbing the bowl about half as often
  • 19% slimmer than the C2 it replaces, so it no longer looks like a fax machine bolted to your toilet
  • Warm-air dryer, deodorizer, and night light are all included — the old C2 had no night light, and Brondell's similarly-priced LE99 drops the deodorizer entirely
  • Ditching the always-on tank cut standby power draw; eco mode plus on-demand heat makes it cheaper to run than tank seats left plugged in 24/7
  • TOTO's docking-station install is genuinely 30-minute DIY — the seat slides off one bracket for deep cleaning and the included tee fits standard 7/8-inch supply lines
  • Both elongated and round versions at the same price — fit flexibility the home-center KS6 sibling doesn't offer

Cons

  • The side arm panel adds about two inches of width — in a narrow alcove it can pinch against a vanity, and unlike the S5 there's no way to add a remote later
  • No user presets: you re-dial pressure, position, and temperature every visit, while the S5/KS6 remote stores four personal profiles
  • The 1,273-watt instant heater demands a dedicated GFCI outlet and the cord is only 3.9 ft — budget for an electrician if your outlet is across the room
  • TOTO's dryer remains the gentlest in the business — owners consistently report 60+ seconds of lukewarm breeze for a job a square of paper finishes in five
  • One-year warranty is stingy next to the 3-year full coverage Bio Bidet puts on similarly-priced seats
  • Launched summer 2025, so there's no long-term reliability record — the C2's decade of proven durability doesn't automatically transfer to the new tankless platform
  • Spray tops out gentler than Korean rivals — r/bidets regulars who want serious pressure point buyers to a Bio Bidet instead of any TOTO
  • List price is $780 and some retailers ask near it — Home Depot and Amazon routinely sell the same seat for $350-430, so never pay list

TOTO's home-center exclusive, replacing the discontinued K300 in the 2025 lineup refresh. Under the lid it's essentially a Washlet S5 — same remote with four user presets, instantaneous heating, EWATER+, PREMIST, night light, dryer, and deodorizer — sold through Home Depot and Amazon at a lower street price (about $500 vs the S5's $650). The trade-off is choice: elongated bowls and Cotton White only. For most buyers it's the value play of TOTO's current range.

The 2025 successor to TOTO's best-selling C5, with the tank heater swapped for instantaneous heating and a 19%-slimmer body. It's the sweet spot of the current S-lineup: wireless remote with four user presets, heated seat, warm-air dryer, deodorizer, new night light, PREMIST, and EWATER+ wand sanitizing. Functionally it's an S2 plus the remote and presets — you're paying roughly $300 for that convenience at a street price around $650.

TOTO's flagship seat, topping the 2026 lineup with a motorized auto-opening and closing lid, EWATER+ misting for the bowl as well as the wand, instantaneous heating, night light, power deodorizer, and a backlit horizontal remote. At 4.1 inches rear height it's among the slimmest seats sold, offered in Classic or Contemporary lid styles and Cotton White or Sedona Beige. MSRP is $2,005 but street pricing runs $1,150-1,400; pair it with a WASHLET+ TOTO toilet for hands-free auto-flush.
