I am making a floor to ceiling cupboard in my bathroom and am looking for concealed hinges to attach the door. In this case, the hinge will need to attach the door to the front face of the cupboard, not the side like most cabinet concealed hinges, in other words, the front of the cupboard and the door are in the same plane. The material is melamine faced chipboard but I don't seem to be able to find any hinges which will do this, can anyone tell me if they exist?
