Find the clean that best fits your body. Adjust water temperature, water pressure, seat temperature and more. All with a tap.

Engineered For Everyone

Bidets are better for everyone. So we specifically designed every bidet to work for every body.

    • Children

    • Elderly

    • Overweight

    • Visually impaired

Front Mode (Feminine)

Bidets can have profound health benefits for women. So we created a female-specific cleaning mode designed exclusively for:

    • Urinary tract and bladder infections

    • Menstruation

    • Pregnancy

    • Inflammatory bowel disease


The built-in warm air dryer eliminates the need for toilet papers.

Heated Seat

Stay goodbye to a cold seat forever with fully-customizable seat temperature settings.

Self Cleaning System

The self-cleaning care system keeps the inside and outside of the bidet hygienic. Giving you better health and peace of mind.

Stainless Steel Nozzle

With the nozzle made from stainless steel, you can wipe off dust easily and always use the product hygienically. Also, the separate cleaning nozzle and bidet nozzle keep the product more hygienic.


IPX5 technology is built to withstand a sustained, low pressure spray, making it easier to keep it safe and sanitary.

ECO Mode

The built-in Eco system switches the bidet toilet to the standby mode when not in use to save the electric power and lower the electric consumption.

Easy Installation

Attaches to most toilet bowls using provided parts and basic tools, without the need for a plumber.
