What are the most common apartment renovation mistakes?

Reading time: ~3 min

The most common apartment renovation mistakes are:

• starting a renovation without a project
• underestimating the budget
• improper electrical installation planning
• plumbing installation errors
• poorly planned lighting
• choosing unsuitable materials
• lack of coordination between contractors

These problems often lead to additional costs, renovation delays, and compromises with the functionality of the home.

Starting a renovation without a project

The biggest mistake is starting a renovation without a functional layout and technical drawings.

Without a project, problems often arise such as:

• outlets in inconvenient places
• changes to installations during renovation
• additional construction activities

Before starting the renovation, it is important to prepare technical drawings that give clear instructions to contractors.

Underestimating the renovation budget

Many renovations exceed the planned budget because they don't account for:

• transportation costs
• additional materials
• unforeseen repairs

Good practice is to plan a reserve of at least 10–20%.

Electrical installation mistakes

Improper planning of electrical points is a common problem.

Most often:

• insufficient outlets
• improperly placed switches
• improperly positioned appliance connections

These problems can be avoided with a well-prepared electrical plan.

Improper plumbing planning

Plumbing installation errors are difficult to correct after the renovation is complete.

Common problems include:

• incorrect sink position
• improper positioning of appliance connections relative to built-in vs. freestanding
• inappropriate pipe height

Poorly planned lighting

Lighting is often underestimated during renovation.

A well-planned lighting plan includes:

• general lighting
• task lighting
• accent lighting

Choosing materials without functionality

Choosing materials based solely on appearance can lead to problems such as:

• low quality and rapid wear
• difficult maintenance
• unsuitable flooring

Lack of coordination between contractors

Renovation usually involves different specialists.

Without clear documentation, it often happens:

• rework
• shifting of responsibilities
• project delays

How to avoid renovation mistakes

The best way to avoid problems is through:

• functional planning
• technical drawings
• clear budget
• good communication with contractors

This makes the renovation more predictable and efficient.

Key Takeaways

• Don't start a renovation without technical drawings and a functional layout.
• Plan a reserve budget of at least 10–20%.
• Plan electrical, plumbing, and lighting before construction starts.
• Choose materials based on functionality, not just appearance.
• Ensure clear documentation for coordination between contractors.
