Final answer:
The word 'bath' in the provided sentence is a singular, concrete, common noun, as it refers to a tangible object that is not a specific name.
Step-by-step explanation:
The word bath as it is used in the sentence 'Super dad had to use all of his powers to get Dog boy into the bath.' is a singular, concrete, common noun. A concrete noun refers to something that can be perceived by the senses, such as an object that can be seen or touched, as opposed to an abstract noun, which represents an idea or concept that is not tangible. The noun 'bath' in this context refers to the physical tub or place where bathing occurs, which is a specific, tangible item and not a particular name of a place, therefore, it's not a proper noun. Also, the word 'bath' is not showing possession of something, so it cannot be a possessive noun, and it refers to a singular entity rather than multiple which excludes it from being plural.
