The TOTO Washlet S7A is the absolute pinnacle of bidet technology in 2026. While the S5 and S7 are excellent, the S7A is designed for those who want a completely hands-free, “zero-touch” bathroom experience. It features an ultra-slim 4.1-inch profile that is significantly less bulky than previous generations, removing that “tacked-on” look from your toilet.
The Real-World Upgrade
The S7A provides an unlimited, instantaneous warm water supply, but its real standout is the automation. It uses a motion-sensing lid that opens as you approach and closes when you leave. Beyond just convenience, the S7A features the most advanced EWATER+ system available, which automatically sanitizes the wand, the bowl, and even the area under the seat after every use. When paired with TOTO’s PREMIST and CEFIONTECT glaze, the toilet virtually cleans itself.
Why It’s the True Flagship
While the S7 offers the same slim design and wash performance, the S7A justifies its flagship status with 4 user memory profiles (compared to just 2 on older models) and a more premium, dual-nightlight system that illuminates both the side of the unit and the bowl. It also includes wide-spray wash modes and a telescoping nozzle for better reach. If you are looking for the best possible hygiene, accessibility, and luxury, the S7A is the definitive choice. As always, make sure you know what shape your toilet bowl is before buying!
