Morphology
The meaning 'a stopper used to seal the drain of a bath' is directly and compositionally derived from 'bath' (the container) + 'plug' (an object that seals or blocks flow). This noun–noun compound follows a regular English modifier+head pattern and is cross-linguistically common, so a B1 learner who knows both words should readily infer the meaning.
Etymology
Bath plug comes from the simple image of a small plug pushed into the bath drain to stop water running out. That's why it means 'a stopper' used to 'seal' the 'drain' so you can fill the tub.
