NYC Landlord is renovating bathroom. Possible Warranty of Habitability violation?

Landlord said renovation will take one week. In the meantime we (a family of four) were told to use the bathroom and kitchen sink (bathroom has no sink) in vacant apartment across the hall. Here’s the problem: The entire apartment is under-construction and completely filthy. It’s filled with dust and reeks of mold. Wood planks, paint chips and huge dry wall pieces are everywhere. Nothing is clean and the air is thick. We also had our water shut off in our apartment for the bathroom reno., so we go back and fourth to brush our teeth/ wash our face/ bathe and fetch water to boil back in our apt. The landlords workers already skipped out on work 2 days in a row (we actually had to call the workers to find out what was up but they insisted everything will be done by Sunday) I’m getting worried and disgusted at how much more I can take. I’m sure landlord would not dare step foot in the vacant apt for his personal care…Should I sue? Also, landlord has a habit of not being on top of repairs
