Step-by-step instructions
Step 1
Measure the pedestal, supply lines, drain, baseboard, and door swing; confirm the cabinet can be removed without disconnecting plumbing.
Step 2
Build two side boxes and a bridge with a removable back or access panel.
Step 3
Use adjustable feet to level the cabinet around the pedestal without loading the sink.
Step 4
Add ventilation gaps and a removable shelf so leaks remain visible.
Step 5
Install anti-tip protection where permitted, then test door and knee clearance.
Do not support the sink with the cabinet or conceal plumbing leaks. Shut off water before plumbing work and consult a licensed professional if clearance or anchoring is uncertain.
