1. Install 2 × 4 blocking between wall studs, behind the planned sink location. Cover the wall with water-resistant wallboard.

2. Set the basin and pedestal in position, bracing the basin with 2 × 4s. Outline the top of the basin on the wall, and mark the base of the pedestal on the floor. Mark reference points on the wall and floor through the mounting holes found on the back of the sink and the bottom of the pedestal.

3. Set aside the basin and pedestal. Drill pilot holes in the wall and floor at reference points, then reposition the pedestal. Anchor the pedestal to the floor with lag screws.

4. Attach the faucet, then set the sink on the pedestal. Align the holes in the back of the sink with the pilot holes drilled in the wall, then drive lag screws and washers into the wall brace, using a ratchet wrench. Do not overtighten.

5. Hook up the drain and supply fittings. Caulk between the back of the sink and the wall when installation is finished.
