The Toto Washlet S7A is what happens when a 100-year-old plumbing company decides the toilet seat is worth perfecting. After a decade of S-series iteration, the S7A is the most refined, most luxurious, and — yes — most expensive bidet seat you can install in a North American home without ripping out the bowl.
Who this is for
If you’re shopping above $1,000 and you want a bidet that feels like a product, not a project, this is the answer. The S7A is for upgraders who have already decided a bidet is non-negotiable and now want the best one money can buy without going integrated.

What we love
- The water never runs cold. Instant heating means you can run the wand as long as you like.
- The auto-open lid is delightful. Approach the toilet; lid opens. Walk away; it closes and flushes.
- EWATER+ keeps the wand clean. Every spray cycle ends with a mist of electrolyzed water across the bowl and wand.
Where it falls short
- Price. At ~$1,800 retail, it’s roughly 3× the Brondell Swash 1400. Worth it for enthusiasts, hard to justify for everyone.
- Power. You’ll need a GFCI outlet within ~3 feet of the bowl. Older bathrooms may need an electrician.
Verdict
If you’ve used a Washlet at a hotel or a friend’s place and thought “I need this” — the S7A is the buy-it-for-life version. If this is your first bidet, start with the Brondell Swash 1400 or Tushy Spa 3.0 and graduate later.
