The Shampoo Buddy will work with your counter if it has a smooth, non-porous surface at least 2 ⅛” wide. Generally, if your sink is undermount style with granite on top, it will work. You can measure to be certain. If you have a drop-in style sink, then you will need to measure the space between the lip of the sink and the edge of the counter. Farmhouse style sinks are not compatible with the Shampoo Buddy.
