Hidden Costs in Kitchen Renovations: What Homeowners Overlook in 2025
Planning Your Dream Kitchen? Don't Let These Costs Surprise You
A kitchen renovation is one of the most rewarding home upgrades, but hidden costs can quickly inflate your budget. While you may plan for cabinets, benchtops, and appliances, there are many overlooked expenses that homeowners encounter mid-project. In 2025, material costs, labour shortages, and evolving design trends make it even more crucial to prepare for unexpected costs. Here’s what you need to know.
1. Structural Changes & Compliance Fees
If you’re knocking down walls, relocating plumbing, or upgrading electricals, you might need permits and engineering reports. These costs vary but can add thousands to your budget, especially if older wiring or plumbing needs to be replaced to meet current building codes.
Estimated cost: $3,000 - $15,000+
2. Custom Joinery & Cabinetry Modifications
Many homeowners underestimate the cost of custom cabinetry. Standard units are budget-friendly, but if you want custom storage solutions, integrated appliances, or unique finishes, costs can double. Soft-close hinges, pull-out pantries, and built-in bins all add up.
Estimated cost: $10,000 - $30,000
3. Benchtop Upgrades & Installation Fees
Choosing premium stone benchtops like marble, quartz, or porcelain can be expensive, but the installation is where costs can catch you off guard. Thicker slabs, waterfall edges, and cut-outs for sinks and cooktops all come with additional charges.
Estimated cost: $5,000 - $15,000
4. Plumbing & Electrical Relocations
If you’re moving the sink, adding an island cooktop, or upgrading to smart appliances, you’ll need additional plumbing and electrical work. Licensed trades are in high demand, meaning longer lead times and higher rates.
Estimated cost: $2,500 - $10,000
5. Luxury Finishes & Unexpected Material Costs
High-end tapware, designer tiles, and premium splashbacks look stunning but often exceed initial estimates. Factor in potential delays or shortages that might require last-minute substitutions, sometimes at a higher price.
Estimated cost: $3,000 - $8,000
6. Project Management & Trade Coordination
Managing multiple trades—builders, electricians, tilers, and painters—can be complex. If you’re working with a high-end renovation company, project management fees may be included. If not, you might need to hire a separate project manager.
Estimated cost: 10-20% of total project value
7. Living Costs During Renovation
Kitchen renovations can take weeks or even months. If you need to dine out or temporarily relocate, factor in these expenses. Alternative cooking setups, like outdoor kitchens or portable appliances, can help reduce costs.
Estimated cost: $500 - $5,000
8. Post-Renovation Cleaning & Styling
Once construction is complete, a deep clean is necessary to remove dust and debris. Professional styling and finishing touches, such as new bar stools or pendant lights, can also push your budget higher.
Estimated cost: $500 - $2,500
How to Budget Wisely & Avoid Surprises

Work with a trusted renovation company to get detailed, transparent quotes
Prioritise must-haves vs. nice-to-haves to keep costs under control
Plan for delays and extra costs by locking in materials and trades early
