Since the bathroom is one of the places in the house where people spend most of their time, yes, it would be very good. But it basically depends upon the remodeled you have made. Not all will help enhance the resale value of your house, or it might not even be a good investment.
Before you sell your home, it is a good idea to have your bathroom remodeled. Remodeling will attract more buyers, and therefore, a better price. Not remodeling will get you low bids.
