10 Common Bathroom Renovation Mistakes (and How to Avoid Them) | Mr Bathrooms Sydney

Bathroom Renovation Mistakes

A bathroom renovation can completely transform your home but only if it’s done right. Many Sydney homeowners make small but costly mistakes that can delay projects, blow budgets, or cause long-term issues. At Mr Bathrooms, with over 30 years of renovation experience across Sydney, we’ve seen it all. Here are the 10 most common bathroom renovation mistakes and exactly how to avoid them.

1. Skipping the Planning Stage

Rushing into demolition without a clear plan leads to confusion and extra costs. Always start with a detailed design and layout plan that includes fixture positions, plumbing, and electrical points.

Tip: Use your floor plan to visualise spacing and flow before work begins.

2. Underestimating the Budget

Many homeowners forget to include essentials like waterproofing, waste removal, or quality tap-ware.

Tip: Allow a 10–15% contingency for unexpected costs and always request a fixed quote from your contractor.

3. Poor Waterproofing

This is one of the biggest hidden problems. Inadequate waterproofing can cause leaks, dampness, and structural damage.

Tip: Only use licensed professionals who comply with Australian Standards AS 3740 & AS 3500.

4. Ignoring Ventilation

Without proper airflow, your beautiful new bathroom can quickly develop mould and mildew.

Tip: Install an exhaust fan or a window for natural ventilation.

5. Choosing Style Over Functionality

Trendy designs are great, but not if they compromise space or storage.

Tip: Balance aesthetics with practicality soft-close drawers, non-slip tiles, and good lighting never go out of style.

6. Hiring Unlicensed Trades

Cheap labour can cost you thousands later in repairs or fines.

Tip: Always verify licences and insurance. Mr Bathrooms uses fully licensed tradesmen for every stage of the renovation.

7. Not Considering Lighting

Lighting makes a huge difference in how your bathroom feels and functions.

Tip: Combine ambient, task, and accent lighting to create both warmth and visibility.

8. Overcrowding a Small Space

Adding too many features in a compact bathroom makes it feel smaller.

Tip: Choose floating vanities, large mirrors, and glass shower screens to open up the room.

9. Forgetting About Drainage

Improper slope or drain placement can cause water pooling.

Tip: Ensure your plumber checks all fall levels before tiling it’s easier to fix before the tiles go down.

10. Not Hiring a Specialist Renovation Company

DIY coordination often leads to delays, poor finishes, and stress.

Tip: A licensed renovation company like Mr Bathrooms Sydney manages everything design, plumbing, tiling, and waterproofing so you don’t have to juggle multiple trades.

Conclusion

Avoiding these common renovation mistakes saves you time, money, and stress. Whether you’re planning a full bathroom upgrade or a small refresh, working with experienced professionals makes all the difference.
