Toto Washlet KS6
~$500

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.

Toto Washlet S5

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.

Toto Washlet S7
~$1,099

Toto / Electric Bidet Seat

Toto Washlet S7

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.

Toto Washlet S7A
~$1,140

Toto / Electric Bidet Seat

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 Washlet S2
~$349

Toto / Electric Bidet Seat

Toto Washlet S2

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.

Toto Washlet A2

Toto / Electric Bidet Seat

Toto Washlet A2

TOTO's true entry point (SW3004, launched 2021 and still current): a tank-heated washlet with a heated SoftClose seat, dual-action rear/front wash with oscillation, and a wired side panel — and nothing else. No dryer, deodorizer, PREMIST, or night light; those start at the S2. With Amazon regularly selling it in the $225-$295 band against a $567 list, it's the cheapest way to put a genuine TOTO wand on your toilet.

Toto / Travel Bidet

Toto Travel Washlet

A pocket Washlet for everywhere your bidet isn't. TOTO's current portable, the YEW4W3 (successor to the long-sold YEW350), collapses to about 5 x 2.5 inches, runs on a single AA battery, and pumps a motorized stream from a 180 ml reservoir through a telescoping wand. Fill it at any sink — warm tap water if you like — pick regular or soft spray, and get a full powered wash cycle. It's a Japan-market staple that reaches the US through import sellers at around $99.
