TOTO doesn't chase features; TOTO refines hygiene. The Washlet C5 adds the two technologies that make a seat noticeably cleaner — PREMIST bowl wetting and EWATER+ nozzle cleaning — alongside the heated everything baseline. The street price swings wide, so timing matters.

The short version
TOTO invented the modern electric bidet seat, and the Washlet C5 is where the company's decades of iteration show: instead of piling on modes, it sweats the cleaning cycle. PREMIST sprays the bowl with water before you use it, EWATER+ cleans the wand with stabilized electrolyzed water after — and both are the kind of quiet engineering that only gets noticed when it's missing.
The seat itself covers the comfort baseline: heated SoftClose seat, warm-air dryer, air deodorizer, adjustable warm-water wash, and a wireless remote with two-user memory. It's also one of the few seats in this roundup positioned for ADA-compliant installations. The catch with TOTO is the channel: street prices run ~$460–$850 depending on seller, and we found no TOTO affiliate program, so BidetKing remains the likely TOTO path for us once feeds go live.
What you get
- PREMIST — water-charged bowl before each use.
- EWATER+ — electrolyzed-water cleaning of the wand and bowl.
- Heated SoftClose seat — adjustable temperature, quiet close.
- Warm-air dryer + air deodorizer — warm dry and odor control.
- Wireless remote with 2-user memory — save your settings.
- ADA-compliant — positioned for accessibility-height installations.

Cons
- Street price swings ~$460–$850 — you have to hunt

FAQ
What does EWATER+ actually do?
EWATER+ is stabilized electrolyzed water sprayed on the wand — and bowl — before and after use. It's a cleaning step, not a disinfectant claim beyond TOTO's own positioning.
Why does the price swing so much?
TOTO sells through many retail channels with different pricing. Street prices have ranged ~$460–$850; Deal Radar watches for the dips.
Is it ADA-compliant out of the box?
The C5 is positioned for ADA-compliant installations in TOTO's catalog — but compliance depends on your total installation (bowl height, clearances). Confirm with your installer.
