Essential Tips for Perth Homeowners Planning a Bathroom Upgrade
Thinking of upgrading your bathroom with a brand-new shower? Whether you’re doing a full renovation or simply replacing an old unit, installing a new shower isn’t just about choosing a design. There are important plumbing, layout, and compliance factors to consider.
This guide breaks down the key things Perth homeowners should know before starting a shower installation project — so you avoid costly surprises and enjoy a smooth, high-quality finish.
1. Know Your Bathroom Layout and Plumbing
Before picking your dream shower, assess your existing plumbing setup:
- Where are the current water pipes and drainage lines?
- Can your water pressure handle a new showerhead or system?
- Is your hot water system compatible? (Especially if you’re upgrading to rain or digital showers)
Tip for Perth homes: In older suburbs like Mount Lawley, South Perth, and Fremantle, plumbing may need upgrading to support new fixtures. If your current system struggles, it’s worth checking whether a hot water system repair or replacement is needed to support the upgrade.
2. Choose the Right Shower Type for Your Needs
There’s more than one kind of shower — and the right one depends on your bathroom size, budget, and water system:
- Mixer Shower – Combines hot and cold water, simple and budget-friendly
- Electric Shower – Heats water instantly, ideal for homes with limited hot water
- Rain Shower – Provides spa-like luxury but requires good pressure and ceiling clearance
- Shower-Over-Bath Combo – Great for smaller bathrooms and family homes
Always discuss your choice with a licensed local plumber to avoid pressure or temperature issues.
3. Water Efficiency Matters
Western Australia’s Water Corporation encourages households to install water-saving fixtures — and that includes showers.
Look for:
- WELS-rated showerheads (minimum 3 stars)
- Flow restrictors to reduce usage
- Efficient systems that save water without compromising pressure
A water-efficient shower can save thousands of litres annually — and lower your utility bills. Pairing a water-efficient shower with other residential plumbing services like tap upgrades or water filtration can maximise savings.
4. Waterproofing Is Non-Negotiable
In Perth, shower installations must meet Australian waterproofing standards (AS 3740). Poor waterproofing can cause:
- Mould and mildew growth
- Timber rot under tiles
- Expensive structural repairs
A licensed plumber or bathroom specialist will ensure the base, walls, and corners are sealed correctly before tiling begins. In some cases, plumbing leak detection can be used to confirm there are no hidden issues behind walls or under floors.
5. Ventilation and Drainage Must Be Spot-On
Moisture control is essential for a healthy bathroom. When installing your new shower:
- Install a suitable exhaust fan for proper airflow
- Check your drain placement and slope for efficient runoff
- Use correct tile gradients to prevent pooling
Poor ventilation is a leading cause of mould in Perth homes — especially during winter. If you notice water backing up in your shower, it could be a sign of a blocked drain that needs attention.
6. Plan for Accessibility and Safety
If you’re future-proofing your bathroom or designing for elderly family members, consider:
- Slip-resistant tiles
- Grab bars for safety
- Walk-in or hobless showers for easy access
- Handheld showerheads for flexibility
These upgrades not only improve comfort but also boost your property’s resale value.
7. Council Approvals and Licensing
Depending on your project scope in Perth, you may need:
- Council approval (for layout changes or drainage alterations)
- Plumbing compliance certificates
- Work done by a licensed plumber
Avoid DIY shower installations — incorrect work can void insurance and lead to costly legal issues.

FAQs – New Shower Installations in Perth
1. Do I need council approval to install a new shower?
Not for basic replacements, but if you’re changing the layout or drainage, check with your local council or building certifier.
2. Can I install a new shower myself?
DIY shower installations are not recommended. Plumbing and waterproofing in Perth must be done by licensed professionals to meet Australian Standards and protect your insurance.
3. Can I keep my old hot water system?
It depends on your new shower’s requirements. Some rain or digital showers need higher flow rates or tempering valves
