3 Bathroom Upgrades You’ll Regret Not Planning Before Tiling
It sounds exciting to remodel a bathroom, but not when the tiles go down.
Because once they do, options disappear. Quickly. Permanently.
According to Australian renovation cost surveys, over 62% of homeowners say their biggest renovation regret was something they didn’t plan early enough, not something they chose wrong. And bathrooms top that list. Why? Because bathrooms hide their complexity behind tiles, walls, and finishes that are incredibly expensive to undo.
At Kongstruction, we’ve seen it countless times. Clients standing in a finished bathroom saying, “I wish we’d thought of this earlier.”
Not because the bathroom looks bad, but because they missed one smart upgrade.
This blog isn’t about luxury for the sake of it.
It’s about bathroom upgrades before tiling that are difficult, disruptive, or downright painful to add later.
This guide is meant to help you avoid the most common bathroom renovation mistakes if you're planning a bathroom renovation or even just thinking about it.
Let’s talk about the three upgrades that matter most before the first tile is laid.
In fact, data from Australian building industry reports shows that post-tiling modifications can increase renovation costs by up to 35%, especially when electrical or waterproofing changes are involved.
This is where planning your bathroom remodel well saves you money and stress.
Let’s be honest.
Cold bathroom tiles in winter are brutal.
After renovations are done, one of the most popular upgrades is to add heating to the floor of the bathroom. This is also one of the hardest to do. Heated bathroom floors must be installed before tiling begins. There’s no workaround that doesn’t involve removing tiles.
A recent renovation industry analysis found that homes with heated bathroom floors command up to 3–5% higher resale appeal in competitive property markets. That makes it one of the most cost-effective modern bathroom upgrades you can make.
But here’s the catch:
It must be part of your bathroom tiling preparation, not an afterthought.
This is one of those things you can't change after tiling the bathroom, and it's one of the most common mistakes people make when they remodel their bathrooms.
Bathroom wall niches and shower niche shelving need to be framed into the wall structure before waterproofing and tiling. When done right, they look planned, neat, and timeless. Later? They look like they were bolted on or not done at all.
Many homeowners later say that not including a niche was one of the biggest mistakes they made when planning their bathrooms. It's a classic example of how to plan bathroom upgrades before tiling, especially in a home renovation project in Coogee, where retrofitting can affect the waterproofing or tile symmetry.
This falls squarely under things to do before tiling a bathroom, not after.
You don’t notice poor bathroom electrical planning on day one.
You notice it every single morning.
Industry research shows that electrical upgrades account for about 40% of post-renovation alteration requests, especially in bathrooms.
This is the answer to the question, "What to install before tiling the bathroom?"
We hear these regrets every week, so they're not just ideas.
Here are the most frequent bathroom renovation regrets homeowners have:
A well-organised bathroom renovation checklist stops these problems and makes sure your renovation lasts long after the excitement wears off. This is especially important for high-end projects like home renovations that Mosman homeowners want to last.
The smartest bathroom renovation Australia projects prioritise:
Whether it’s a full build or a custom bathroom renovation, early planning determines long-term satisfaction.
Every improvement we've talked about, like heated floors, wall niches, and electrical planning, is one that you should plan ahead for in your bathroom.
At Kongstruction, we believe the best renovations feel effortless because the hard thinking happened early. Before we tile the bathroom, we make sure that nothing is left to chance and that nothing important is forgotten.
If you’re planning a renovation, don’t rush the invisible decisions.
They’re the ones you’ll live with the longest.
Make a smart plan. Make it once. And let Kongstruction help you get it right before you put down the tiles.

Let’s talk about the three upgrades that matter most before the first tile is laid.
Why Planning Before Tiling Matters More Than You Think
Bathroom tiling preparation isn’t just about aesthetics. It’s about infrastructure. Once tiles are installed:- Plumbing and electrical access becomes limited
- Structural changes become costly
- Waterproofing integrity is at risk if altered
- Labour costs multiply if demolition is required
In fact, data from Australian building industry reports shows that post-tiling modifications can increase renovation costs by up to 35%, especially when electrical or waterproofing changes are involved.
This is where planning your bathroom remodel well saves you money and stress.
Upgrade #1: Underfloor Heating (The Comfort Feature Everyone Wishes They Added)
Let’s be honest.Cold bathroom tiles in winter are brutal.
After renovations are done, one of the most popular upgrades is to add heating to the floor of the bathroom. This is also one of the hardest to do. Heated bathroom floors must be installed before tiling begins. There’s no workaround that doesn’t involve removing tiles.
Why Heated Bathroom Floors Are a Smart Move
Underfloor heating isn’t just about comfort. It improves efficiency and usability.- Heats the space evenly from the ground up
- Reduces reliance on wall heaters
- Helps floors dry faster, reducing mould risk
- Adds long-term property value
Is Underfloor Heating Worth It in Bathrooms?
Short answer: yes—when planned early.A recent renovation industry analysis found that homes with heated bathroom floors command up to 3–5% higher resale appeal in competitive property markets. That makes it one of the most cost-effective modern bathroom upgrades you can make.
But here’s the catch:
It must be part of your bathroom tiling preparation, not an afterthought.
This is one of those things you can't change after tiling the bathroom, and it's one of the most common mistakes people make when they remodel their bathrooms.
Upgrade #2: Built-In Wall Niches & Smart Storage (The Detail That Changes Everything)
Storage is one of those things people assume they’ll “figure out later”. Bathrooms punish that assumption.
Bathroom wall niches and shower niche shelving need to be framed into the wall structure before waterproofing and tiling. When done right, they look planned, neat, and timeless. Later? They look like they were bolted on or not done at all.
Why Niches Beat Afterthought Storage
Built-in niches solve multiple problems at once:- Eliminate cluttered shelves and caddies
- Keep shower areas clean and streamlined
- Improve daily usability without adding bulk
- Enhance resale appeal through concealed bathroom storage
Do You Need a Shower Niche?
If you value functionality, yes.Many homeowners later say that not including a niche was one of the biggest mistakes they made when planning their bathrooms. It's a classic example of how to plan bathroom upgrades before tiling, especially in a home renovation project in Coogee, where retrofitting can affect the waterproofing or tile symmetry.
This falls squarely under things to do before tiling a bathroom, not after.
Upgrade #3: Electrical Scheduling and Extra Power Points (The Daily Regret You Face)
This one sneaks up on people.You don’t notice poor bathroom electrical planning on day one.
You notice it every single morning.
How Many Power Points Should a Bathroom Have?
There isn't a single answer, but most bathrooms that have been remodelled need more than you think. Think about daily use:- Hair dryers and straighteners
- Electric toothbrushes
- Shavers
- Heated towel rails
- Smart mirrors or lighting
Industry research shows that electrical upgrades account for about 40% of post-renovation alteration requests, especially in bathrooms.
What Should Be Planned Before Bathroom Tiling?
Electrical conduits, switch placements, and outlet positions must be finalised before walls are closed and tiles installed. This is why bathroom plumbing and electrical planning should happen together, early.This is the answer to the question, "What to install before tiling the bathroom?"
Typical Bathroom Renovation Mistakes (And How to Prevent Them)
Let’s pause for a moment.We hear these regrets every week, so they're not just ideas.
Here are the most frequent bathroom renovation regrets homeowners have:
- Skipping heated bathroom floors
- Not adding enough storage
- Underestimating electrical needs
- Focusing on tiles over functionality
- Rushing decisions without a checklist
A well-organised bathroom renovation checklist stops these problems and makes sure your renovation lasts long after the excitement wears off. This is especially important for high-end projects like home renovations that Mosman homeowners want to last.
Where Most Renovations Go Wrong
A lot of people pay more attention to finishes than to basics. Colours, tiles, and taps. All of them are important, but not the most important.The smartest bathroom renovation Australia projects prioritise:
- Infrastructure first
- Usability second
- Aesthetics third
Whether it’s a full build or a custom bathroom renovation, early planning determines long-term satisfaction.
