10 Common Bathroom Refit Mistakes (And How to Avoid Them)

Avoid costly errors in your bathroom renovation. From poor ventilation to bad lighting, we cover the top pitfalls.

Planning a Bathroom Renovation? Avoid These Common Pitfalls

Bathrooms are one of the most challenging rooms to renovate due to tight spaces and complex plumbing requirements. Here are the top 10 mistakes homeowners make and how to avoid them.

1. Poor Ventilation

Inadequate ventilation leads to mold, damp, and condensation. Always install an extractor fan that meets building regulations - preferably one with a timer and humidity sensor.

2. Insufficient Lighting

One central ceiling light isn't enough. Layer your lighting with task lights around the mirror, ambient ceiling lights, and accent lighting for atmosphere.

3. Incorrect Waterproofing

Skipping tanking (waterproofing) in wet areas is a recipe for disaster. Always use moisture-resistant boards and waterproof membranes in shower areas.

4. Poor Space Planning

Not allowing enough clearance around fixtures makes the bathroom cramped and uncomfortable. Leave at least 700mm in front of the toilet and basin.

5. Choosing Style Over Function

That beautiful polished marble floor looks stunning but becomes dangerously slippery when wet. Always prioritize safety and practicality.
