Electric Bidet Seat

Launched April 7, 2026, the 200N is Coway's new entry point to the Bidetmega line, replacing the aging Bidetmega 200. It keeps the brand's signature i-wave 3-stage wash (soft start, main wash, rinse - up to 120 seconds), adds a wireless remote with dual user profiles, a night light, Air+ bubble-infused spray, and a hybrid heater that sustains continuous warm water. Elongated only, $429 list, and already discounting hard on Amazon.

Coway Bidetmega 400S
$449
Electric Bidet Seat

Coway retired the original Bidetmega 400 and replaced it in 2025 with this 400S — same design-award-winning minimalist look, now with instant tankless heating and 'Triple Hygiene Care' (anti-stick WaterShield bowl mist, auto-cleaning stainless nozzle, and UV nozzle light). Its signature i-wave system runs automated multi-stage wash courses that vary pressure, temperature, and motion. Lists at $599 direct but typically sells around $450 on Amazon.

Coway Bidetmega 500S
$449
Electric Bidet Seat

Coway's flagship seat and the only Bidetmega with a motorized auto open/close lid, driven from a Bluetooth remote for a fully touchless visit. Triple Hygiene Care stacks WaterShield anti-contaminant misting, automatic nozzle cleaning, and UV nozzle sterilization on top of instantaneous tankless heating, i-wave washing, a deodorizer, and night light. Lists at $699 but routinely sells in the $400-500 range, straddling premium Totos like the S7.
