When updating your kitchen or bathroom, one of the most common questions homeowners face is whether to replace just the sink faucet or go for a full installation that includes the sink, plumbing, and accessories. The difference in cost between these two projects can be significant — and understanding what’s included in each can help you make the right financial choice for your home.
Average Cost Overview
The cost to replace a sink faucet typically ranges from $150 to $500, depending on the faucet type, labor, and materials. In contrast, a full sink installation (including the faucet, sink basin, drain assembly, and plumbing connections) can range from $400 to $1,000 or more.
Here’s a quick comparison:
| Project Type | Average Total Cost | DIY Cost | Professional Cost |
| Faucet Replacement Only | $150 – $500 | $50 – $200 | $200 – $500 |
| Full Sink Installation | $400 – $1,000+ | $200 – $600 | $500 – $1,000+ |

Faucet Replacement Cost Breakdown
If your sink is still in good condition, replacing just the faucet is the more budget-friendly option. The main expenses include:
- New Faucet:
- Basic models: $50 – $100
- Mid-range or pull-down models: $100 – $250
- Touchless or designer faucets: $250 – $500+
- Labor Costs:
Hiring a professional plumber typically adds $100 – $300, depending on the complexity and accessibility under the sink. - Supplies and Materials:
Minor extras like plumber’s tape, gaskets, or water lines usually cost under $30.
Replacing a faucet usually takes about 1 to 2 hours for a professional, or 2 to 4 hours for a confident DIYer.
Full Sink Installation Cost Breakdown
A full installation involves replacing both the sink and faucet, which means additional labor and materials. Here’s what you’re paying for:
- Sink Basin:
- Stainless steel or porcelain: $150 – $400
- Composite granite or farmhouse style: $400 – $800+
- Faucet and Accessories:
Add another $100 – $400 for the faucet, depending on the style and finish. - Plumbing and Drain Assembly:
Replacing drainpipes, p-traps, or shut-off valves can cost $50 – $150 extra. - Labor Costs:
Professionals typically charge $200 – $500 for full installations, depending on whether any additional plumbing work is required. - Countertop Adjustments:
If you’re changing the sink size or shape, cutting or modifying the countertop can add $100 – $300 to the final bill.
Key Differences Between Faucet Replacement and Full Installation
| Feature | Faucet Replacement | Full Installation |
| Scope of Work | Replaces faucet only | Replaces faucet + sink + drain |
| Average Time | 1–2 hours | 3–5 hours |
| Labor Involved | Low to moderate | Moderate to high |
| Cost Range | $150 – $500 | $400 – $1,000+ |
| Ideal For | Minor upgrades | Full kitchen or bathroom renovation |
Essentially, faucet replacement is perfect for refreshing the look and function of your sink without major disruption, while full installation is best suited for remodels or when the existing sink is damaged or outdated.
DIY vs. Professional Installation
If you’re comfortable with tools and have some plumbing knowledge, replacing a faucet can be a manageable DIY project. However, full sink installations often require more skill and precision — especially when connecting drain lines, securing heavy sinks, or modifying countertops.
Professionals ensure a leak-free, code-compliant installation and often include a warranty for their labor. To explore which option suits your budget and skill level, visit Builtup Home for a complete guide comparing DIY versus professional installation costs.
Tips to Save on Replacement or Installation Costs
- Buy the Faucet and Sink Separately: You can often find better deals online or during seasonal sales.
- Bundle the Job: If you’re replacing multiple fixtures (like the garbage disposal), doing them together reduces overall labor charges.
- Stick to Standard Sizes: Choosing standard faucet holes and sink dimensions avoids costly countertop modifications.
- Maintain Your Fixtures: Regular cleaning and maintenance help extend the lifespan of your faucet and sink, delaying replacements.
Final Thoughts
The cost to replace a sink faucet vs. a full installation depends mainly on your goals and budget. If your sink is still functional and you just want an aesthetic or functional upgrade, replacing the faucet alone is a smart, cost-effective choice.
However, if your sink is damaged, outdated, or leaking, investing in a full installation provides long-term reliability and a refreshed look. Whether you go DIY or hire a professional, comparing prices and knowing what’s included can help you make the most of your investment — and Builtup Home offers excellent resources for homeowners seeking transparent cost comparisons and expert installation advice.
