Toto Washlet S7

Model SW4726AT40#01

Warm wateryes
Needs an outletyes
Heated seatyes

TOTO's 2023-generation flagship, one rung below the S7A we also track — and the two are near-identical: same instantaneous heating, EWATER+ bowl-and-wand sanitizing, PREMIST, 4-user presets, and illuminated remote. The only real difference is the S7A's motorized auto open/close lid; the S7's lid is manual. Sold in Classic or Contemporary lid styles, Cotton White or Sedona Beige, elongated or round, at roughly $1,030-$1,225 street.

Best for Buyers who want TOTO's flagship wash tech but think a self-raising lid is a party trick, not a feature.

EWATER+ Bowl Cleaning
4 User Presets
S7A Minus Auto Lid

What owners like

+Identical wash engine to the $1,299 S7A — endless instantaneous warm water, PREMIST, and the same spray modes — for around $200 less at street prices
+EWATER+ mists both the wand and the bowl with electrolyzed water after every use, a bowl-cleaning trick the S2 and S5 don't fully replicate — owners report noticeably less ring scrubbing
+Four user presets (position, pressure, temperature) — the deepest memory in TOTO's lineup; the S5 stores fewer and the S2 stores none
+Rare flagship flexibility: Classic or Contemporary lid, Cotton White or Sedona Beige, and a true round-bowl version (SW4725) — most premium seats are elongated-only
+2-year warranty, double what TOTO gives the S2/S5
+WASHLET+ (AT40) design hides the hose and cord completely on matching TOTO toilets, and it's auto-flush capable with the optional kit

Common complaints

−No auto open/close lid — literally the one feature separating it from the S7A; when the price gap narrows to ~$100-150 during sales, most shoppers just buy the S7A
−At $1,000+ street it costs three S2s, and the S2 delivers the same core warm-wash experience minus the luxury trimmings
−The remote dropped the older S550e's LCD screen — programming four user presets by button-and-beep takes trial and error
−Auto flush needs a separate kit and only works on select TOTO toilets — on anything else you're still reaching for the handle
−Instantaneous heating pulls serious wattage, so TOTO wants a dedicated GFCI circuit — shared bathroom circuits can nuisance-trip
−Warm-air dryer is quiet but slow like every bidet dryer — expect 60-90 seconds or a courtesy dab of paper anyway

Questions buyers ask

What's actually different between the S7 and the S7A?

Just the motorized auto open/close lid — the wash engine is identical: same instantaneous heating, EWATER+ bowl-and-wand sanitizing, PREMIST, four user presets, and illuminated remote. The S7 runs about $200 less at street prices, but when sales narrow the gap to $100-150, most shoppers just buy the S7A.

Does the S7 need special wiring?

TOTO wants a dedicated GFCI circuit because the instantaneous heater pulls serious wattage — on a shared bathroom circuit it can nuisance-trip the breaker. If your only outlet also runs a hair dryer or space heater, budget for an electrician before you budget for the seat.

Will the warm water run out mid-wash?

No — the S7 heats water instantaneously rather than storing it in a tank, so warm water is endless. That's the core upgrade over tank-heated seats that give you 30-60 seconds before turning cold.

Is there a version for round toilet bowls?

Yes — the SW4725 is a true round-bowl version, which is genuinely rare at the flagship tier where most premium seats are elongated-only. You also get a choice of Classic or Contemporary lid and Cotton White or Sedona Beige.

How much does EWATER+ actually reduce cleaning?

After every use it mists both the wand and the bowl with electrolyzed water, and owners report noticeably less ring scrubbing than with seats that only rinse the wand. It's a maintenance reducer, not a replacement — you'll still clean the bowl, just less often.

Toto Washlet S7A

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.

Toto / Electric Bidet Seat

Toto Washlet S5

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.

Heating: Tankless
Control: Wireless Remote
Install: 30-45 min DIY
Warranty: 1-year limited

Remote + 4 Presets
Endless Warm Water

Toto / Electric Bidet Seat

Toto Washlet KS6

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.

Heating: Tankless
