Possibly. Even though an accident occurs on private property does not mean that the property owner is responsible for such injuries.
An injured party needs to show that the property owner had a duty to keep the bathroom floor in a clean and safe condition, that the property owner breached the duty (by failing to clean the bathroom floor or failing to repair a leaking sink as examples), that the slip and fall on the water on the floor caused the actual medical injuries, and that the injured party suffers actual damages.
Establishing each element is the definition of negligence under Nevada law and would document a case against a property owner for negligence.
