Product overview
Built for informed sourcing
The B04 is an elongated electric bidet seat for compatible existing toilets. A side knob starts rear or front washing and adjusts the water volume; the adjacent buttons adjust water, drying and seat temperature settings. The upper seat closes softly, and a seat sensor controls the in-use functions.
The documented configuration uses 100–130V AC at 50/60Hz, 0.07 MPa dynamic to 0.75 MPa static water pressure and 4–35 °C supply water. The B04 series includes rear and front washing, a four-level seat temperature setting, three-level water temperature adjustment, LED night light and IPX4 protection. Warm-air drying is marked as model-dependent in the manual.

Rear and front washing
The side knob starts rear or front washing and regulates the water volume. Water temperature has three adjustment levels when powered.
Heated seat with four settings
Seat temperature can be adjusted across four levels, including heating off. A sitting sensor enables the in-use controls.
Model-dependent warm-air drying
Some B04 models include warm-air drying with three air-temperature levels; the manual identifies this function as model-dependent.
Side control and soft close
The integrated knob and buttons provide local control, while the upper seat uses a soft-close mechanism.
IPX4 enclosure and LED night light
IPX4 protection and an LED light source are documented in the product parameters for bathroom installation planning.
Compatible-toilet upgrade format
Fast-mounting hardware, a side water inlet, inlet hose and tee-junction support installation on a compatible existing toilet pan.
