"I'm surely going to have to wash the bathtub."
Translation:Je vais sûrement devoir laver la baignoire.
howcheng; If you really want to learn French you need to consult a dictionary when you want to define a word. It will also help you with memorizing the gender of nouns. Personally I use: https://www.dictionnaire-academie.fr/ but if your just beginning you might try using: https://www.larousse.fr/dictionnaires/francais-anglais/ or several other French-English dictionaries. Do not use google or other translators as these often give results that are not entirely correct. That said, the difference between 'laver = to wash (out), to scrub' and 'nettoyer = to clean'.
