Homeowners search “cost to replace bathroom sink” every day because the price of a seemingly small upgrade can swing from modest to eye-watering. At CountBricks, we specialise in residential construction and use AI-driven estimating to remove the guesswork. Below, we break down typical sink replacement costs, the factors that push budgets up or down, and how CountBricks keeps your numbers accurate from the first phone call to the final invoice.
Across our recent Louisville-area projects, a straightforward sink swap starts around $450 and climbs to $1,600 when custom vanities, designer fixtures or corrective plumbing are involved. National averages land in the same ballpark, but material pricing and labour availability can move local numbers by 10-15 %. CountBricks feeds live supplier data into every estimate, so your quote always reflects today’s pricing—not last quarter’s catalog.
• New sink and faucet: $120 – $800 depending on material and style
• Vanity or countertop modifications: $150 – $600
• Plumbing labour and parts: $140 – $450
• Disposal, sealing, finishing: $40 – $150
• Contingency for hidden issues (water damage, rotted studs): 10 % of project total
1. Sink Type and Material – Undermount porcelain is affordable, while cast concrete or stone composites can triple material cost.
2. Faucet Complexity – A single-hole mixer installs faster than a wide-spread three-hole set, reducing labour hours.
3. Existing Plumbing Condition – Corroded shut-off valves or non-standard trap assemblies add parts and time.
4. Vanity Size Changes – Expanding from a 24-inch to a 36-inch cabinet triggers countertop and possibly floor patching work.
5. Scheduling Window – After-hours or rush-order requests usually include premium labour rates.

In residential construction, small jobs can suffer from “round-it-up” pricing. Over-estimating by $200 on a sink replacement may seem harmless, but multiply that across several punch-list tasks and homeowners either delay projects or cut corners. CountBricks’ AI keeps every line item data-driven, protecting both client wallets and contractor margins.
