The Hamiltonian variational method is applied to the SU(2) lattice gauge theory in d+1 dimensions using a plaquette-independent ansatz. The calculations in the equivalent model have been performed using a mean-field approach in plaquette variables. We obtain only one confining phase. Possible generalizations are also discussed.
