A bathroom renovation can add value, functionality, and style to your home, but it's a project that requires careful planning and execution. Many homeowners make costly mistakes that lead to delays, budget blowouts, and unsatisfactory results. To ensure your renovation goes smoothly, here are some of the most common mistakes to avoid.

1. Poor Planning and Budgeting

One of the biggest mistakes is failing to plan properly. Without a clear design and budget, unexpected costs and delays can arise. To avoid this:

  • Set a realistic budget, including a buffer for unforeseen expenses.



  • Plan the layout and materials before starting any demolition.



  • Consult with professionals to ensure your vision is achievable.



2. Ignoring Ventilation

Bathrooms are exposed to high levels of moisture, and poor ventilation can lead to mould and mildew problems. Common ventilation mistakes include:

  • Not installing an exhaust fan or choosing one that's too small.



  • Failing to place ventilation correctly near the shower or bath area.



  • Relying solely on windows for airflow, which isn't always effective.



Investing in proper ventilation will help prevent long-term damage to your bathroom.

3. Choosing the Wrong Materials

Bathrooms require materials that can withstand moisture and frequent use. Some mistakes to avoid include:

  • Using non-waterproof paint, which can peel or develop mould.



  • Selecting porous tiles that absorb water and stain easily.



  • Choosing low-quality cabinetry that warps over time due to humidity.



Always opt for durable, water-resistant materials that are specifically designed for wet areas.

4. Overlooking Storage Needs

A well-designed bathroom should provide enough storage without feeling cramped. Common mistakes include:

  • Not incorporating built-in storage solutions like recessed shelves or mirrored cabinets.



  • Choosing a vanity that's too small or lacks sufficient drawers.



  • Not considering storage for everyday essentials like towels and toiletries.



Planning your storage effectively will keep your bathroom organised and functional.

5. Poor Lighting Placement

Lighting is often an afterthought, but it plays a crucial role in both aesthetics and functionality. Avoid these mistakes:

  • Relying only on ceiling lights, which can create shadows.



  • Not installing task lighting around the mirror for better visibility.



  • Using bulbs that are too dim or too harsh, affecting the ambience.



Layered lighting with a combination of overhead, task, and accent lighting will enhance the overall look and usability of your bathroom.

Avoiding these common mistakes can save you time, money, and frustration during your bathroom renovation. By planning carefully, choosing the right materials, ensuring proper ventilation, incorporating smart storage, and optimising lighting, you can create a stylish and functional space that stands the test of time.
