Why Upgrade to a Washlet Toilet?

A washlet is an advanced toilet seat or system that includes bidet functions such as warm water cleansing, adjustable pressure, and air drying. Many models also offer heated seats, deodorizers, and auto-flush features. Combined with a modern toilet, it creates a cleaner, more efficient experience and reduces the need for paper products.
