10 HDB Bathroom Renovation Mistakes to Avoid

Planning a bathroom upgrade in your HDB flat? A successful HDB bathroom renovation can greatly improve your home’s comfort, value, and style. But without proper planning, what should be a refreshing makeover can quickly turn into a stressful and costly experience.

To help you make informed choices, we’ve listed ten common mistakes to avoid during your HDB bathroom renovation. Whether you're going for a modern look or a practical upgrade, these tips will save you both time and money.

1. Not Planning Properly

Jumping straight into renovation without a proper plan is one of the biggest mistakes you can make. A rushed design process often leads to a bathroom that doesn’t suit your needs, has awkward layouts, and leaves you full of regrets. 

For instance, while mosaic tiles can look beautiful on bathroom floors or walls, they may not be the most practical choice. Mosaic designs have many grout lines, which can easily trap dirt, making the surfaces look dirty over time and much harder to maintain. Without careful planning, you might end up with a bathroom that looks good initially but quickly becomes a headache to clean and maintain.

Tip: Before finalising your layout and fittings, take the time to think about how you use your bathroom daily. Consider storage, movement, lighting, and your overall style preferences and also what you want to prioritise: aesthetics, easy maintenance, or practicality.

2. Ignoring HDB Regulations and Permits

HDB flats have strict renovation guidelines, such as prohibiting the expansion of bathroom areas by more than 20% or relocating wet areas. Ignoring these rules can lead to penalties, renovation delays, or even having to undo completed work. Be sure to check with our friendly staff who are well-versed in HDB regulations before starting your project!

Tip: Always check HDB renovation rules before starting. Certain works, like hacking tiles, plumbing changes, and waterproofing, require prior approval. Hiring an HDB-registered contractor, like us at The Design Factory, accredited with BizSafe Level 3, helps ensure your renovation is fully compliant and safely executed.

3. Poor Ventilation

Bathrooms are often damp and humid, creating the perfect environment for mould and mildew to grow. While mould may seem harmless at first, it can pose significant health risks. If not addressed promptly, it can spread beyond the bathroom and into main living areas like bedrooms. Poor ventilation can also lead to lingering smells and cause long-term damage to surfaces.

Tip: To prevent mould growth, ensure your bathroom has good air circulation by installing an exhaust fan, ducted ventilation, or a window. You can also consider using anti-mould paints and newer options like light-fan combinations, which are now available on platforms like Taobao.

4. Using the Wrong Materials

Using the wrong materials in a high-moisture environment like a bathroom can cause a range of problems over time. For example, regular paint may start to peel or bubble due to constant exposure to humidity. Non-water-resistant wood can swell, warp, or even rot, leading to costly repairs. Additionally, flooring materials not designed for wet areas can become dangerously slippery, increasing the risk of accidents.

Tip: Choose water-resistant materials to enhance durability, safety, and hygiene. At The Design Factory, we offer ABS trimming to seal cabinetry edges and prevent moisture damage. You can also opt for our stainless steel cabinets for maximum resilience. For painted finishes, we use an oil-based sealer for added protection. Additionally, we recommend homogeneous floor tiles for their superior strength and water resistance.

5. Not Planning for Storage

Bathrooms tend to get cluttered quickly if there’s not enough storage space. Skipping this step may result in items left out in the open, making your bathroom look messy.  

Tip: Consider built-in cabinets, floating shelves, vanity units with hidden compartments, full-length mirror cabinets, or even wall niches to keep toiletries, cleaning supplies, and other clutter neatly tucked away.

6. Inadequate Lighting

A bathroom with poor lighting can feel dark and unsafe. On the other hand, overly harsh lights can be unpleasant, especially during your morning routine.

Tip: Use a mix of lighting sources—overhead lights for general use, task lighting near mirrors, and soft ambient lighting for a relaxing atmosphere.

7. Choosing Cheap Fixtures

While it might be tempting to save money on taps, showerheads, or toilets, going for the cheapest option can cost you more in the long run due to frequent breakdowns.

Tip: Invest in good-quality fixtures that are durable and come with warranties. Reliable fixtures will serve you better and require less maintenance over time. 

8. Overlooking Accessibility

A bathroom that looks good but isn’t comfortable to use—especially for children, the elderly, or anyone with mobility issues—can become frustrating or even dangerous.

Tip: Think ahead and incorporate universal design elements like grab bars, anti-slip flooring, and walk-in showers for added safety and convenience.

9. Overcomplicating the Design

Sometimes, less is more. An overly complex design with too many materials or bold patterns can make the space feel cramped and difficult to maintain.

Tip: Stick to a simple, cohesive design with a neutral colour palette. This not only creates a timeless look but also makes cleaning and upkeep easier.

10. Hiring Unqualified Contractors

Trying to cut costs by hiring unlicensed or inexperienced contractors often backfires, resulting in poor workmanship, project delays, and even higher expenses down the line. These contractors may lack the necessary skills, proper permits, and understanding of safety regulations, leading to mistakes that require costly repairs and can put the entire project at risk.

Tip: When choosing a professional for your project, always opt for licensed and experienced contractors who are familiar with HDB regulations. This ensures that your work complies with legal standards and avoids potential penalties. Take the time to research reviews and examine their portfolio of past projects to assess the quality of their work.
