Red Flag or Ok? - I recently started a new job with a small company.

The woman who interviewed me seemed very eager and friendly and the type of work is what I was looking for--they hired me right away. On the first day I learned they bought a new computer for me (yay) and another employee donated a desk (it's a new position.) When I was given the tour, I was told not to use the kitchen sink because it has a permanent blockage that they plan to get fixed and that the office has no hot water. I didn't think any thing of it until a couple days later when I found out that the sink has been broken for as long as they've owned the building (8 years!!!) Also they seemed in no hurry to get my employee paperwork together until I mildly insisted. I don't know if this is just characteristic of a small business environment (10 people) or a red flag that they won't take care of the team. There is also some more recent flood damage that I've been told will be fixed by March of next year (there is an insurance claim.) Should I be worried or is this within the realm of OK for a small company? Thank you!
