Why My Kitchen Renovation Cost $40K | The Real Story
The Real Reason My Kitchen Renovation Cost $40K
No fancy joinery materials. No expensive natural stone. No custom luxury taps or hardware. And yet, my own kitchen renovation cost still hit $40K — when the original budget was $30K. How? A mix of unexpected expenses, a few change-of-mind moments, and some upgrades along the way.
I wouldn’t call my kitchen high-end or luxury, but it’s definitely high-function.
I’m not here to scare you off, but the truth is things rarely go exactly as planned. Even though I work in the industry, there were still plenty of surprises I couldn’t avoid. Renovations are simply harder to predict than a new build, where construction costs can be calculated with more accuracy.
A common mistake is only budgeting for the “big three”:
- Joinery
- Benchtop and splashback
- Appliances
I wish it were that simple! If you only look at those categories, $40K might sound excessive. But kitchen renovation costs involve so much more than the pretty finishes you see on Pinterest.
And honestly, I’m a little over the endless posts bragging about $10K or $20K kitchen makeovers. Those numbers make a good social media hook, but they don’t tell you about all the hidden costs. Yes, you could recreate the look of my kitchen for less — but you’d sacrifice durability, functional features, and proper workmanship, which only leads to maintenance problems down the track.
So instead, I’m here to share my real experience — the ups, the extras, the unexpected — so you can plan more carefully and get a clearer picture of what a kitchen renovation cost really looks like.
1. Older Homes Come With Surprises
My house was built in the 70s, back when standards, regulations, and building methods were very different. That means you never really know what’s hiding behind the walls until demolition begins. In my case, there was no plaster behind the original joinery, so we had to replaster the entire area before anything new could go in.
This is often the source of those “unexpected repair” costs that blow out a budget. Even if you have the original plans, you can’t guarantee that every renovation or modification from the last 10–20 years was done to code. Sometimes you think a wall is safe to remove, only to discover the builder didn’t follow the plan at all. These kinds of surprises add thousands to your kitchen renovation cost.
2. Electrical Upgrades Are Almost Inevitable
The second big budget buster? Electrical work. Most older homes simply aren’t equipped to handle the power needs of today’s kitchens. My switchboard hadn’t been updated in over 20 years, so when it came time to install modern appliances, I had no choice but to upgrade.
It’s not the most exciting part of a kitchen renovation, but it’s one of the most important. Without it, your shiny new appliances either won’t run properly or could pose safety risks. This is another hidden cost that social media “$10K kitchen” stories almost never mention, but it’s a very real part of bringing an old kitchen up to modern standards.
3. Drawers, Drawers, and More Drawers
For a kitchen that isn’t even huge, I went all in — 20 drawers. Yes, 20! I added them everywhere possible, even inside the pantry where you can’t actually see them. I’m a big believer in drawers for storage. They’re simply more functional than cupboards, but they definitely aren’t the budget option.
Most budget “standard” kitchens might only include 2–6 drawers, usually just for cutlery or bowls. So, when you push that number up to 20, the kitchen renovation cost rises quickly.
On top of that, I chose special hardware for some spaces — like a corner pull-out system and a large pull-out bin with four compartments. These upgrades look invisible from the outside (a drawer front looks like a door until you pull it open), but they’re hidden features that cost extra. The payoff? A kitchen that’s far more functional day to day.
If you’re renovating for a rental or short-term stay, you could skip the extra drawers and stick with cabinets to keep costs down. But if you’re like me — a little obsessed with organisation — investing in drawers and upgraded hardware is absolutely worth it.
4. The Rangehood That Cost More to Install Than to Buy
One of my biggest surprises came from the rangehood. I had already decided on a Qasair rangehood — they’re famous for their super-powerful suction and solid ducting (far more expensive than flexible ducting). I thought installation would be simple. My kitchen has no upper floor above it and is close to the exterior wall — easy, right?
Wrong.
It turned out there was a timber beam exactly where the ducting needed to go. That one beam doubled the installation cost, plus required extra ducting to work around it. Suddenly, my premium rangehood became the single most expensive appliance in the whole house — not because of the unit itself, but because of the installation.
Do I regret it? Not at all. The quality is amazing, it’s unbelievably powerful, and it’s low-maintenance. But it was a harsh reminder: when you choose premium appliances, you’re also choosing premium installation costs and premium accessories.
For context, a standard rangehood installation usually costs around $300–$500. A Qasair rangehood? Over $1000 just for installation. In my case, it went past $2000, all thanks to that one stubborn timber beam.
Moral of the story: don’t just look at the sticker price of an appliance — always ask about the accessories, special ducting, and installation costs that might come with it.
5. Splurging on Appliances
Because this is a home I plan to live in for a long time, I chose to invest in the best appliances I could afford. They weren’t as pricey as my rangehood, but I didn’t hold back either — and these choices definitely pushed up the total kitchen renovation cost.
Some of my favourites:
- Bosch dishwasher with auto-open after the cycle finishes (life-changing for drying).
- Franke sink with a super-slim edge, installed countertop-mounted for low maintenance but with a premium finish.
- Pyrolytic oven that cleans itself, saving hours of scrubbing.
The thing about appliances is the price gap is huge. For example:
- A budget dishwasher can be $500, while a premium model is closer to $2000.
- A basic oven starts around $700, but a high-end pyrolytic oven can easily be $4000+.
- A standard Bunnings sink might cost $200, while a premium sink is $1000–$2000.
These differences add up quickly. What you choose — and how much you value functionality — has a massive impact on your overall budget.
6. The Little Things That Add Up
Finally, there were all the smaller details that don’t often make it into other people’s renovation stories — but they still made a difference to my total kitchen renovation cost.
- Extra power points: My old kitchen had hardly any, so I added a lot more.
- Painting walls and ceilings: Because it’s an older house, a full repaint was necessary. We also swapped in brighter downlights, which meant the ceiling had to be painted properly, not just patched up.
- Pantry finishes: Instead of the standard white melamine board inside, I chose wood-look materials so my pantry feels as good as it looks. Even though it’s hidden, I wanted my dry goods to feel beautifully displayed.
On their own, these upgrades don’t sound like much — a few hundred dollars here, a few hundred there. But together, they add up to thousands, quietly inflating the budget.
Other Things That Can Easily Impact the Price
Beyond my own experience, there are plenty of other factors that can quickly shift your kitchen renovation cost up or down. Some of these are outside your control, while others depend on the choices you make:
- Size of your kitchen – A larger footprint means more cabinetry, more benchtop, and more flooring. Even if you choose budget finishes, sheer volume adds cost.
- Level of finish – Standard laminate versus premium two-pack joinery, engineered stone versus porcelain slab, budget tapware versus designer fixtures — these choices can double or triple costs in an instant.
- Flooring – When you tear out an old kitchen, you often affect the existing floor. If that floor runs through the rest of the house, the kitchen work may create a mismatch that forces you to continue flooring into adjoining spaces. This is why many people start out “just doing the kitchen” and end up tackling half the house.
- Trades and labour rates – Plumbers, electricians, carpenters, and tilers don’t all charge the same. Prices vary by location, complexity of work, and even how busy they are at the time.
- Plumbing and gas relocation – Keeping sinks, dishwashers, and cooktops in their existing spots saves money. Moving them to new locations adds significant cost.
- Structural changes – Removing or shifting walls, reinforcing beams, or upgrading old flooring can add thousands you didn’t originally budget for.
- Compliance and permits – Older homes may need upgrades to meet current building codes. And in some cases, council approvals or permits are required, adding both time and money.
Each of these can affect your budget far more than you expect. This is why two people can both say “my kitchen renovation cost $40K” but have completely different reasons for how they got there.
So, that’s how my “$30K kitchen” turned into a $40K reality. It wasn’t about chasing luxury, marble benchtops, or custom designer fittings — it was a mix of hidden repairs, smart functionality upgrades, and those little details that quietly add up.
If there’s one thing I’ve learned, it’s that kitchen renovation cost is rarely just about cabinets, benchtops, and appliances. Older homes throw surprises, premium appliances come with premium installation, and even something as small as adding drawers or repainting ceilings can shift the budget dramatically.
The point isn’t to scare you off — it’s to help you plan better. When you understand all the moving parts, you’ll go into your renovation with clearer expectations and far less stress when the inevitable “extras” appear.
While my kitchen isn’t luxury or high-end, it is high-function. Every dollar I spent has made it a space I love to use every single day. That, to me, is worth it.
If you’re planning your own renovation, take the time to budget beyond the “big three.” Think about appliances, electrical, flooring, painting, and those little details that turn a kitchen from okay into outstanding.
Because at the end of the day, a kitchen isn’t just about looks — it’s about how it works for you. And that’s where the real value lies.
