A bathroom remodel is one of the most impactful home improvement projects, enhancing both functionality and aesthetic appeal. However, mistakes in the remodeling process can lead to costly repairs and unnecessary stress. At Addition Building & Design, Inc., we’ve seen common pitfalls that homeowners encounter and how to prevent them. Here are four rookie bathroom-remodeling mistakes—and how to avoid them.

1. Ignoring Proper Ventilation

One of the biggest mistakes homeowners make is overlooking ventilation. Without proper airflow, moisture accumulates, leading to mold growth, peeling paint, and long-term structural damage.

How to Avoid It:

• Invest in a high-quality exhaust fan suited for the size of your bathroom.
• Ensure the fan vents outside, not into an attic or wall cavity.
• Consider adding a window if possible to promote natural ventilation.

2. Choosing Style Over Functionality

It’s easy to get caught up in trendy designs, but prioritizing aesthetics over functionality can lead to an impractical space. A bathroom should be as efficient as it is stylish.

How to Avoid It:

• Plan a layout that maximizes space and accessibility.
• Select durable, water-resistant materials that withstand daily use.
• Incorporate sufficient storage solutions, such as recessed shelves or built-in cabinets, to reduce clutter.

3. Poor Lighting Choices

Lighting plays a crucial role in both the ambiance and functionality of a bathroom. A single overhead light may not be sufficient, making tasks like shaving or applying makeup difficult.

How to Avoid It:

• Layer lighting with a mix of ambient, task, and accent lighting.
• Install vanity lights on either side of the mirror to minimize shadows.
• Consider dimmable lighting options to create a relaxing atmosphere when needed.

4. Underestimating the Budget

Many homeowners start a remodel without a clear financial plan, only to face unexpected costs that exceed their budget.

How to Avoid It:

• Establish a realistic budget that includes a contingency fund (typically 10-20% of the total cost) for unexpected expenses.
• Work with experienced professionals to get accurate cost estimates.
• Avoid cutting corners on essential components like plumbing and waterproofing, as these can lead to expensive repairs later.
