Please help, I am having some kitchen remodeling done and the contractor took out the sink today, now I have no water coming out from my bathroom showers or sinks. He did not connect a new sink yet and said he only turned off the valve under the sink, does anyone know what would cause the rest of the water in the house not to work?

Do you have water in toilets ?

If positive, than you probably have dirt in areators and shower head. Remove aerator, clean it, reinstall. Remove shower head, clean it and reinstall.

Thank you for the reply, I do have water in the toilets but only a little bit, before the contractor removed the kitchen sink everything worked fine, is it possible that there is a shutoff valve that I am missing? I do have a hot water heater could that have something to do with it?

Yes, it is very possible your contractor shut off main water valve due to leaking kitchen sink angle stops. Locate the main valve, usually on the exterior of your house, open it. Just be careful that your angles stops under kitchen sink are closed.
