Vanity Replacement and Plumbing Planning: What to Check First

A bathroom vanity replacement may look simple, but the details behind the cabinet often determine how smoothly the project goes.

Plumbing location, shutoff valves, drain alignment, drawer clearance, countertop choice, faucet spread, mirror height, and lighting all need to coordinate.

Before ordering a vanity, review these planning points.

Measure the existing vanity and wall space

Start with the current width, depth, height, and sink location. Then measure wall-to-wall clearance, door swing, toilet clearance, and any trim or outlet conflicts.

A vanity that fits the old footprint may still conflict with plumbing, drawers, or baseboards.

• Overall vanity width and depth
• Sink centerline and drain location
• Door and drawer clearance
• Outlet, mirror, and light fixture positions

Check shutoffs and supply lines

Hot and cold shutoff valves should close fully and be accessible after the new vanity is installed. Old valves, corroded fittings, or tired supply lines can turn a cabinet replacement into a plumbing delay.

If the new vanity has drawers, the plumbing may need adjustment so the drawers work properly.

Coordinate countertop and faucet choices

A countertop may come pre-drilled for a specific faucet spread, or it may require separate fabrication. The sink type, faucet style, backsplash, and drain assembly should be selected together.

Wall-mounted faucets require a different rough-in than deck-mounted faucets and should be planned before wall repairs or tile work.

Plan the wall finish behind the vanity

Removing the old vanity can reveal paint lines, wall damage, old caulk, or missing flooring. If the new vanity is smaller or floating, the wall and floor behind it may become visible.

This is also a good time to decide whether a tile backsplash is part of the scope.
