Abstract: Models with a nonequilibrium wetting transition display a transition also infinite systems. This is different from nonequilibrium phase transitions into anabsorbing state, where the stationary state is the absorbing one for any valueof the control parameter in a finite system. In this paper, we study what kindof transition takes place in finite systems of nonequilibrium wetting models.By solving exactly a microscopic model with three and four sites and performingnumerical simulations we show that the phase transition taking place in afinite system is characterized by the average interface height performing arandom walk at criticality and does not discriminate between the bounded-KPZclasses and the bounded-EW class. We also study the finite size scaling of thebKPZ universality classes, showing that it presents peculiar features incomparison with other universality classes of nonequilibrium phase transitions.
