Bathroom Vanity Installation Cost Guide

Evidence note: project cost ranges are editorial planning allowances, not observed contractor-bid averages. Contextual references do not independently establish every allowance. Confirm the complete scope with local written quotes.

A complete vanity replacement commonly needs a $1,800–$7,500 allowance including cabinet, top, sink, faucet, removal, plumbing connection, and installation. Custom millwork and wall changes can move it higher.

Planning guidance for professionally completed US projects. Local quotes, site conditions, material selections, permits, and access determine the actual price and schedule.

What the allowance includes

A realistic budget combines the cabinet, countertop, sink, faucet, hardware, delivery, removal, plumbing reconnection, wall repair, and installation. Mirrors, lighting, backsplash, and electrical work may be separate.

Stock versus semi-custom or custom cabinetry
Integrated top versus fabricated stone
Single versus double sink
Same-location valves and drain versus relocation
Freight, stairs, and wall scribing

Common cost surprises

Old shutoff valves, damaged drywall, out-of-level floors, nonstandard drain heights, and missing wall blocking often appear after removal. Double-sink conversions usually require more plumbing and countertop work than buyers expect.

Measure before purchase

Confirm finished width, depth, door swing, drawer clearance, plumbing locations, backsplash height, mirror and outlet positions, and the path from delivery point to bathroom.

RenoCostData decision brief: compare the actual scope

Define cabinet, top, sink, faucet, plumbing, backsplash and restoration. Matching cabinet widths do not make two installed packages equivalent.

Decision	Get this in writing	Comparison trap
Product package	Cabinet, top and sink inclusions	Cabinet-only versus complete package
Fit	Connections, wall fixing and clearance	Relocation and fillers assumed free
Restoration	Paint, backsplash and old footprint	Smaller cabinet exposes unfinished surfaces

Worked comparison—not a market quote

A hypothetical $1,200 cabinet plus $700 top and sink plus $250 faucet is $2,150 before tax, delivery and labor. A $1,500 package may include the top but not the faucet. Rebuild both product lists before concluding it saves $650.

Your next step

Record dimensions, drawer clearance and drain position. Confirm who purchases products and handles damaged deliveries.

Keep supporting documents with the estimate comparison and budget worksheet. This editorial analysis is not an inspection or professional certification.
