With assistance, carefully lift the sink and place it onto the installed wall brackets. Align the mounting holes on the underside of the sink with the corresponding holes in the brackets. Insert the provided bolts from underneath and use an Allen wrench to tighten them, making the bottom of the sink firm and stable.
Goal: Attach Sink to Brackets
- Tighten the bolts evenly to avoid putting undue stress on any single point of the sink.

FAQs
Why is wall blocking necessary for a pedestal sink, and what type of wood should I use?
Wall blocking provides crucial structural support for the sink basin, which often doesn't have a vanity beneath it and must bear its own weight. Use a sturdy piece of lumber like 2 in. x 8 in. Prime Lumber, ensuring it's securely fastened horizontally between wall studs to prevent the sink from pulling away from the wall over time.
The project estimates 12 hours; what factors contribute to this longer installation time for an intermediate project?
The 12-hour estimate accounts for several factors beyond simple assembly, including the time-consuming process of removing an old sink and potentially repairing the wall. Locating studs, installing robust wall blocking, and carefully running new PEX water lines can add significant time. Additionally, waiting for caulk to cure before final use is essential for a leak-free finish.
What are the most critical steps to ensure a leak-free plumbing connection for my new pedestal sink?
Always apply thread sealant tape (Teflon tape) to all threaded pipe connections before tightening. For the PermaFLOW ABS Slip Joint P-Trap, ensure all slip-joint nuts are hand-tightened, then given an additional quarter turn with Channellock pliers. Double-check all connections by running water and visually inspecting thoroughly for any drips before proceeding to caulk.
How do I ensure the sink basin and pedestal are perfectly level and securely mounted to prevent wobbling?
During the 'Dry Fit' step, use a level to mark precise mounting locations for the basin, ensuring it's plumb and level before drilling. Secure the basin firmly to the wall blocking using #10 3” wood screws. Position the pedestal directly beneath the basin's drain tailpiece, using shims if necessary to achieve perfect stability on uneven floors.
