"Wheytub" is a unique word with an unusual spelling. Its correct pronunciation can be understood with the help of IPA phonetic transcription, which shows that it is pronounced /weɪtʌb/. The spelling is derived from the two words, "whey" which refers to the liquid that separates from milk when cheese is made and "tub" which is a cylindrical container made of wood, plastic or metal commonly used for holding liquids. Therefore, "wheytub" can be interpreted as a tub or container for whey.
