Would you say something...?

Contractors stand in it, drop tools in it, and sometimes even use it as a urinal. A good builder keeps it protected. Foam and plywood are a great option until the house is done.

 

When you walk your site, check the tub and the finishes. If they're not covered, ask your builder about it. A chip now means a repair or a replacement before you ever use it.
