Score: 88/100Rankings
The Kohler PureWash E815 is a high-end electric bidet seat that converts standard elongated toilets into luxury fixtures with instant-heated water and remote-controlled washing modes. It features a stainless steel self-cleaning wand and oscillating 3D wash, positioning it as a mid-to-upper tier option. It is best suited for homeowners with nearby GFCI outlets who want full electric bidet features.
The TOTO WASHLET S2 is a premium electronic bidet seat featuring a 19% slimmer profile, instantaneous tankless water heating, and advanced hygiene technologies like EWATER+ and PREMIST. Its reliance on side-arm controls and weak dryer airflow are notable trade-offs. It is best suited for hygiene-focused households and elderly users who benefit from SoftClose and nightlight features.
