Step 5 · Position Pedestal and Secure Basin
Carefully slide the pedestal base under the loosely mounted sink basin, aligning it with the bottom of the basin. The pedestal's primary role is support, not bearing the full weight, which is handled by the wall bolts. Check again that the sink basin is level side-to-side and front-to-back using your level. Make any necessary adjustments by slightly moving the sink on the bolts. Once everything is perfectly aligned and level, fully tighten the nuts on the lag screws to secure the sink basin firmly to the wall. Alternate tightening the nuts to apply even pressure. Some pedestals have holes in the base for securing it to the floor with screws; if so, mark these holes, move the pedestal, drill pilot holes, and secure it to the floor.
