Replacing a Bathroom Sink and Countertop: A Cost Breakdown
Updating your bathroom's vanity can significantly enhance its aesthetics and functionality. Replacing the sink and countertop is a common DIY project, but it's essential to understand the costs involved. This guide will help you budget for this home improvement task.
Factors Affecting the Cost
The total cost of replacing a bathroom sink and countertop depends on several factors:
- Material: The cost varies significantly based on the material you choose, from affordable options like laminate to high-end materials like marble.
- Size: Larger sinks and countertops require more material and may have higher installation costs.
- Installation: If you hire a professional, labor costs will add to the total expense.
- Additional Features: Features like built-in sinks, undermount sinks, or custom countertops can increase the cost.
Sink Costs
Sinks are typically sold separately from countertops. Here's a breakdown of sink costs:

- Pedestal Sinks: These are free-standing and range from $50 to $500, depending on the material and style.
- Under-mount Sinks: These are installed underneath the countertop and range from $100 to $1,000+.
- Vessel Sinks: These sit on top of the counter and range from $100 to $1,000+.
Countertop Costs
Countertop costs vary greatly depending on the material. Here's a rough estimate:
- Laminate: $20 - $100 per square foot
- Solid Surface (like Corian): $40 - $150 per square foot
- Granite: $50 - $200 per square foot
- Marble: $60 - $250 per square foot
- Quartz (engineered stone): $60 - $200 per square foot

If you're not replacing the vanity yourself, you'll need to factor in installation costs. Professionals typically charge by the hour or the job. Here's a rough estimate:
