Hand Held Bidet Sprayers can be easily installed on all 1-piece and 2-piece toilets and are not limited by the shape of a toilet. Just hook it up to the cold water source and it'll work just like a shower head. Want to be able to use warm water? The Brondell Hot / Cold Mixing Valve Upgrade Kit allows you to draw warm water from the sink (or a warm water source nearby), providing a more comfortable spray during those cold winter days.
