The biggest renovation selections mistakes I see homeowners make
After working with homeowners across the Illawarra, Sutherland Shire and Southern Highlands, I've noticed something interesting.
Most people don't make renovation mistakes because they have bad taste.
They make them because they're trying to make hundreds of decisions without a clear plan.
By the time most clients come to me, they've already spent hours scrolling Pinterest, saving Instagram posts and wandering through tile showrooms. They have plenty of ideas, but they're struggling to pull everything together into a home that feels cohesive and considered.
Here are some of the most common renovation selection mistakes I see - and how to avoid them.
1. Choosing finishes in isolation
This is probably the biggest mistake of all.
You fall in love with a tile. Then a tapware finish. Then a stone benchtop. Then a paint colour.
Individually, each selection is beautiful.
Together? Not always.
One of the most important parts of the design process is understanding how every finish relates to the others. Materials, colours and textures need to work together to create a cohesive whole.
Before selecting anything, I recommend establishing an overall vision for your home. Every decision becomes easier when you have a clear direction.
2. Following trends too closely
Trends aren't inherently bad. In fact, many trends become popular for good reason.
The problem is when homeowners make expensive, permanent decisions based solely on what's popular right now.
I've seen people choose tiles, tapware and cabinetry colours because they're everywhere on social media, only to realise a few years later that they don't actually suit their home, personal taste or lifestyle.
The best interiors have longevity.
Rather than asking, "What's trending?" I encourage clients to ask, "Will I still love this in ten years?"
3. Underestimating the importance of lighting
Lighting is one of the most overlooked elements of a renovation.
Many homeowners spend months selecting tiles and paint colours but leave lighting decisions until the very end. Or worse still, leave all the lighting placement decisions to the builder or electrician who don’t know how you truly plan on living in your home.
Good lighting isn't just about choosing attractive fixtures. It's about creating the right mood, supporting the way you live and ensuring your home feels warm and inviting throughout the day.
A beautiful room with poor lighting usually feels just a bit off.
4. Making decisions too late
Renovations involve hundreds of moving parts, and many selections need to be finalised much earlier than people expect.
Delaying decisions can lead to:
rushed selections
limited product availability
construction delays
costly changes during the build
The earlier you establish your design direction and begin making selections, the smoother the renovation process tends to be, and the more likely you’ll end up with a home you love.
5. Forgetting how the home will actually be used
A beautiful home should also be a practical one.
It's easy to become focused on aesthetics and overlook how a space will function day to day.
Before making any selection, I encourage clients to think about:
how they live
who uses the space
maintenance requirements
durability
long-term practicality
The best design solutions balance beauty and functionality.
6. Trying to make every decision alone
This may sound self-serving coming from an interior designer, but hear me out.
Most homeowners renovate only once or twice in their lives.
The decisions can feel overwhelming because there are so many of them, and the stakes are high. Mistakes can be expensive.
One of the biggest benefits of working with an interior designer isn't necessarily access to products or suppliers.
It's having someone help you make confident decisions and create a cohesive plan from the outset.
Many of my clients tell me the greatest value wasn't the selections themselves—it was the peace of mind that came from knowing they were making the right choices.
Final thoughts
A successful renovation isn't about choosing the most expensive finishes or following the latest trends.
It's about creating a home that feels cohesive, functional and uniquely suited to the people who live there.
Renovations often involve investments of hundreds of thousands of dollars, yet many homeowners make critical design decisions with little guidance. Investing a small portion of your renovation budget in professional design advice can be one of the smartest decisions you make.
A designer won't just help you choose beautiful finishes. They'll help you avoid costly mistakes, create a cohesive vision and make confident decisions from the outset.
If you're planning a renovation in the Illawarra, Sutherland Shire or Southern Highlands and would like help navigating the selection process, I'd love to help. A one-off consultation is a great place to start the journey.
