I want to order a replacement part for my bathtub, but I don’t know what it is called (in Dutch or in English) and that makes an on-line search hard. Hope someone can help me out!
Bathtubs have an drain higher up, to keep the bath from overflowing. Usually that drainhole is covered with a knob like stop that can be turned to adjust the water level. The knob is metal of plastic, and they stick in your back if you sit in the tub the wrong way around.
What is that knob called?
