What Should I Include in a Bathroom Renovation Budget?

(Spoiler: there’s way more to it than tiles and tapware!)

I’ll be honest — the first time I attempted to create a bathroom renovation budget, I wildly underestimated the cost.
I thought, “How hard can it be? New toilet, some tiles, a fancy tap… done!”
Oh, how wrong I was.

If you’re anything like me, you might’ve started a Pinterest board, picked a few dreamy inspo photos, and suddenly
found yourself deep in the world of tapware finishes and tile patterns. And then comes the real question every
Wollongong homeowner eventually asks:

“Okay, but what should I actually include in my bathroom renovation budget?”

Great question — and in this article, I’m going to break it all down for you. We’ll go beyond just fixtures and tiles
and explore all the hidden, sneaky, and often-forgotten costs that can blow your budget if you’re not prepared.

By the end, you’ll know exactly what to include, how to estimate costs, and how to avoid unexpected surprises so your
bathroom renovation goes smoothly from start to finish.

1. Overview: Why Your Budget Needs More Than You Think

A bathroom is a small space, but it’s one of the most complex rooms in your home. It involves plumbing, electrical,
waterproofing, tiling, carpentry and more — all happening in a tight area.

That’s why a bathroom renovation budget needs to be detailed. Without a clear breakdown, things can spiral quickly.
The key categories you must include are:

  • Demolition & preparation
  • Plumbing work
  • Electrical work
  • Waterproofing
  • Tiling & labour
  • Fixtures & fittings
  • Joinery & storage
  • Ventilation
  • Compliance costs
  • Contingency funds

Let’s break these down one by one so you know exactly what to plan for.

2. Demolition & Strip-Out Costs

Before anything looks better, it’s going to look a whole lot worse. Demolition involves:

  • Removing old tiles
  • Stripping vanities, toilets and baths
  • Tearing out old wall linings
  • Clearing debris and disposing of waste

Your budget should include:

  • Labour for demolition
  • Skip bin hire
  • Disposal fees

This stage can cost anywhere from a few hundred dollars to a couple of thousand depending on complexity, tile thickness,
and whether the room has hidden surprises (like water damage or asbestos).

3. Plumbing Works & Plumbing Fixtures

Plumbing is one of the biggest components of your budget. This includes:

  • New pipes and drainage
  • Relocating plumbing fixtures
  • Installing taps, shower mixers and toilets
  • Fitting baths and basins

Important: Moving plumbing around is far more expensive than keeping the layout the same.

Your plumbing fixtures budget should include:

  • Toilet
  • Vanity
  • Shower head
  • Bath (if applicable)
  • Tapware
  • Drain wastes

Quality matters — cheap plumbing fixtures tend to fail sooner and can cost more long-term.

4. Electrical Works & Lighting

Most bathroom remodels need electrical upgrades. Your budget should include:

  • Lighting installation
  • Exhaust fans
  • Power points
  • Heated towel rails
  • LED mirrors or backlit mirrors

Lighting is one of the biggest contributors to your bathroom’s ambience — dimmable LEDs, backlit mirrors, and
directional lighting can dramatically improve the look.

5. Waterproofing Essentials

Waterproofing is not optional — it’s legally required in NSW and must be done by a licensed professional.

Your budget should include:

  • Waterproofing membranes
  • Labour for waterproofing
  • Certification

Skimping here can cause catastrophic leaks, structural damage, mould growth and insurance problems.

6. Tiles, Labour & Grouting

Tiling is often the biggest labour component of a bathroom renovation. You should budget for:

  • Floor tiles
  • Wall tiles
  • Feature tiles
  • Tile glue, grout and trims
  • Tiling labour

Costs vary based on:

  • Tile size (large format vs mosaics)
  • Tile material (porcelain vs stone)
  • Complexity of patterns
  • Whether you tile floor-to-ceiling

Tiling can easily eat a third of your budget — so choose wisely!

7. Fixtures, Fittings & Stylish Extras

This is where your bathroom’s personality comes alive. Your budget should include:

  • Shower screens
  • Basin and bath mixers
  • Toilet roll holders
  • Towel rails
  • Mirrors
  • Soap niches
  • Shelving

You might also want to allocate additional budget for luxuries like:

  • Freestanding baths
  • Rain shower heads
  • Smart mirrors
  • Underfloor heating

These upgrades aren’t essential — but they absolutely elevate the space and boost comfort.

8. Carpentry, Joinery & Custom Storage

Carpentry is often forgotten in the budget but plays a big role. This includes:

  • Replacing rotten framing
  • Building niche shelving
  • Installing new door frames
  • Custom bathroom cabinetry

Custom joinery can significantly improve storage and style but can add thousands to the budget.

9. Ventilation, Fans & Moisture Control

Bathrooms in Wollongong need good ventilation — especially in coastal suburbs where humidity is high.

Your budget should include:

  • A quality extraction fan
  • Ducting and installation
  • Optional window upgrades

Poor ventilation is one of the biggest causes of mould — so it’s definitely worth investing in.

10. Labour & Trades Management

This is one of the most underestimated parts of the budget. Bathroom renovations often involve:

  • Carpenters
  • Electricians
  • Plumbers
  • Tilers
  • Waterproofers
  • Glaziers
  • Painters

Labour typically makes up 40–60% of your total renovation cost.

You should also budget for:

  • Project management fees
  • Scheduling and coordination
  • Site cleanup

11. Permits, Approval Fees & Compliance

Many bathroom renovations in Wollongong don’t need council approval, but you should still budget for:

  • Plumbing approvals
  • Electrical certificates
  • Waterproofing certification
  • Strata approval fees (if applicable)

Approval fees vary depending on the complexity of the project.

12. The Contingency Fund (The Most Important Part!)

No matter how well you plan, bathrooms love to throw surprises at you:

  • Rotten floorboards
  • Mould behind walls
  • Old pipes that need replacing
  • Unlevel floors
  • Electrical upgrades

This is why you MUST include a contingency of at least 10–20% in your budget.

The older the home, the more important this buffer becomes.

13. Hidden Costs Homeowners Often Forget

Even with the best planning, some things slip through the cracks. Commonly forgotten costs include:

  • Rubbish removal
  • Temporary bathroom arrangements
  • Patching and painting adjoining rooms
  • Unexpected plumbing upgrades
  • New doors, handles or trims
  • Delivery fees for tiles and fixtures
  • Extra waterproofing layers

Adding these into your initial budget prevents nasty “surprise” invoices later.

14. Tips to Keep Your Renovation Budget On Track

14.1 Keep the same layout

Moving the toilet or shower can add thousands in plumbing work.

14.2 Choose tiles strategically

Feature tiles look amazing, but they’re often expensive and costly to install. Use them sparingly for maximum effect.

14.3 Pick mid-range fixtures

You don’t need top-shelf tapware for a high-end look — mid-range brands offer great quality without the price blowout.

14.4 Set a firm budget beforehand

And stick to it. Constant changes will blow out both your timeline and your wallet.

14.5 Work with an experienced renovation team

Professionals know how to avoid mistakes, schedule trades efficiently and help you avoid unnecessary costs.

15. Final Thoughts & Recommended Experts

A bathroom renovation budget should include far more than just tiles and tapware. From demolition to waterproofing,
plumbing to labour, ventilation to joinery and everything in between, the more detailed your budget, the smoother
your renovation will run.

By planning for every category (and keeping that contingency fund handy!), you’ll avoid surprises and enjoy a beautiful,
functional, and long-lasting bathroom.
