Our take on the TOTO WASHLET K300

The TOTO WASHLET K300 is an electric bidet seat for elongated toilets. It heats water instantly with a tankless system, so the warm spray runs continuously instead of running out like tank reservoirs. It adds a heated seat, a deodorizer and self-cleaning nozzles, and it comes with a remote, mounting bracket and tee connector. It suits people who want a full-featured bidet seat without stepping up to TOTO's higher-end models, which add features like a premist and auto-open lid.
