Our take on the TOTO Washlet KS6 Bidet Toilet Seat SW3946#01

The TOTO Washlet KS6 (SW3946#01) is an elongated bidet toilet seat with a remote control, warm-water washing, oscillating spray, automatic deodorizer and TOTO's EWATER+ wand cleaning. It fits WASHLET+ toilets and needs a water supply plus a GFCI outlet nearby. At $440.10 at Ferguson Home as of November 5, 2026, it sits at the low end of its recent range across 8 stores, so this is a good moment to buy.
