The invention relates to the technical field of home decoration boards, in particular to an integrated wall protecting board. The integrated wall protecting board comprises wall protecting board unitsand is characterized in that each wall protecting board unit comprises an outer shell and a wall water pipe arranged on the inner side of the outer shell; clamping connectors are arranged among the wall protecting board units and comprise outer shell connectors among the outer shells and water pipe fasteners among the wall water pipes; each water pipe fastener comprises a convex face and a concave face on left and right sides of the corresponding wall water pipe, and the clamping connectors are matched to enable close contact of the water pipe fasteners. By design of the wall protecting boardwith the water pipes, water pipe unit replacement can be realized by replacement of the wall protecting board, single modular maintenance can be realized, and accordingly convenience in maintenance and low cost are realized.
