What to Know Before Starting Your Shower Recess Renovation

Planning to renovate your shower recess? Before you start ripping out tiles or ordering fixtures, there are key things you need to know. A successful bathroom renovation requires more than just choosing a new vanity or tap. You’ll need to plan for plumbing, waterproofing, tile selection, and fixture placement to avoid delays and costly mistakes.

Whether you’re upgrading a bath to a freestanding tub, replacing an old toilet, or just installing a new shower fixture, knowing what’s involved will help you save time and money.

Here’s what every homeowner should understand before starting a shower recess renovation.

1. Bathroom Renovation Planning: Things to Consider Before You Start

Before you remove tiles or purchase a new vanity, start with proper planning. Every successful bathroom renovation begins with a clear vision and a realistic plan.

Define your bathroom design goals:

• Gather inspiration from mood boards or online galleries
• Think about features you want: shower niche, freestanding bathtub, frameless shower screen, or rainfall shower head
• Consider how you want your new bathroom to feel—modern, natural, minimalist?

Budget wisely:

Don’t underestimate the cost of a bathroom renovation. Include not just materials and fittings, but also labour, permits, and potential structural repairs. Add 10–15% buffer for unexpected issues like water damage or having to remove tiles and re-screed the shower floor.

Measure your space:

Make sure you have accurate floor plans. Pay attention to floor space, access points, and whether there’s enough room for a double vanity, heated towel rails, or wall-mounted fixtures.

Check regulations:

If you’re in Adelaide or another regulated area, contact your local council. Most bathroom renovations require approval, especially those involving electrical and plumbing work.

2. Waterproofing, Plumbing, and Ventilation — Non-Negotiables in Any Bathroom Reno

Water damage is one of the biggest risks in any bathroom remodel. That’s why getting the foundations right is more important than choosing fittings or finishes.

Waterproofing the shower recess:

The shower recess must be waterproofed up to at least 1800mm high—or 50mm above the shower head, whichever is higher. You may also need to waterproof the entire tile floor area, depending on your layout. Waterproofing must follow Australian Standards and be completed by a qualified professional.

Plumbing and drainage:

Moving plumbing fixtures can increase costs significantly. Keep existing pipes in place when possible to stay within budget. Always hire a licensed plumber to handle any water supply, waste lines, or adjustments to your bathtub, vanity, or tapware.

Good ventilation matters:

Poor airflow leads to mould growth, especially in tight, damp spaces. Always include an exhaust fan or improve natural light with a skylight or window. Proper ventilation is key to preventing moisture build-up behind walls and tiles.

Electrical safety:

Plan for powerpoints, lighting, underfloor heating, and any future upgrades. Always use a qualified electrician to ensure compliance with local building codes.

3. Bathroom Design Tips to Build Your Dream Bathroom

Design isn’t just about looks—it’s also about how your bathroom functions day to day. Don’t make decisions based only on trends; think about practical, long-term comfort.

Lighting layers:

Mix ambient lighting with task lighting around mirrors and showers. Consider dimmable lights or LEDs in niches and shelves for a polished touch.

Smart storage:

Add a shower niche, built-in cabinets, or wall-mounted linen shelves to maximise your bathroom storage. Even a tiny bathroom can benefit from clever use of space.

Choose the right fixtures and fittings:

From frameless shower screens to wall-mounted tapware, choose items that are both stylish and easy to clean. Avoid bulky items in small spaces.

Shower or tub?

If you want to keep both, go for a freestanding tub and a walk-in tiled shower with a glass screen. If space is tight, opt for a combined bath-shower with a shower curtain or partial screen.

4. Choosing the Right Materials and Tiles

Your choice of tiles affects not only the style but also the durability of your bathroom. Always use water-resistant materials for both the walls and floor.

Floor tiles vs. wall tiles:

Use non-slip tiles on the shower floor, and easy-to-clean tiles on the walls and recess. Look for products rated for wet areas.

Grout and screed matters:

Use mould-resistant grout and make sure your shower floor has the correct fall for drainage. The screed underneath must also be correctly applied to prevent pooling.

Re-tiling vs. full strip-out:

If you’re simply updating tiles, check the waterproofing and substrate underneath first. In many cases, a full removal is more effective than simply replacing fixtures or surface tiling.

5. Professional Help: Know When to Call a Plumber, Tiler, or Electrician

Bathroom renovations require multiple trades. Don’t assume it’s a DIY job unless you have experience.

Hire a tiler for perfect alignment, slope, and clean grout lines.
Use a plumber to manage water connections for your new shower head, tapware, toilet, or bathtub.
Bring in a licensed electrician to install powerpoints, lights, and exhaust systems safely.

Make sure all professionals provide insurance, ABNs, and certifications. Don’t settle for anyone who cuts corners—it will cost more later in repairs.

6. Small but Important Details Often Overlooked

These may seem minor but can affect your day-to-day use and long-term satisfaction.

• Take photos before demolition – Useful for locating pipes and wires later
• Confirm door width – Make sure it allows access to larger appliances like a washer
• Plan shampoo storage – Include a shower niche or shelf for daily items
• Think of future needs – Accessibility upgrades like grab bars or curbless entries
• Fresh coat of paint – Can change the entire bathroom feel affordably
• Natural light – Improves mood and airflow; consider adding or enlarging a window
• Underfloor heating – Great for comfort in colder climates

These extra steps make your bathroom renovation not just functional, but enjoyable for years to come.

FAQs

What are the key waterproofing tips for a shower recess renovation?

Use a high-quality waterproof membrane applied in two coats at 90° to each other, allowing drying time between coats. Pre-cut reinforcing fabric for corners and drainage outlets is essential. Extend waterproofing at least 150mm above the shower floor and seal all corners and penetrations tightly to prevent leaks. Follow Australian Standards AS 3740-2010 for best results.

How should I plan outlet placement for my new shower area?

Plan electrical outlets outside the immediate wet zone for safety, ideally at least 1 metre away from the shower recess. Consider locations for vanity outlets, smart toilets, or bidets. Ensure all outlets are installed by a licensed electrician and comply with local electrical safety regulations to prevent water-related hazards.

Is reglazing an old bathtub a cost-effective alternative to replacement?

Yes, reglazing can be a cost-effective option to refresh an old bathtub’s surface without full replacement. It saves money and time, maintaining the tub’s structure while improving appearance. However, it’s best for tubs in good condition without major cracks or damage.

What design ideas can make my shower feel more spa-like on a budget?

Incorporate built-in niches for storage, use large-format tiles for a sleek look, add a rain showerhead, and include a simple bench or stool. Use calming neutral colours and upgrade fixtures to matte black or brushed nickel for a modern feel. Adding plants or soft lighting can enhance the spa atmosphere affordably.

Why is proper ventilation crucial during bathroom shower renovations?

Proper ventilation prevents moisture buildup that causes mould, mildew, and structural damage. It ensures air circulation to dry wet surfaces quickly, protecting your bathroom’s longevity and indoor air quality. Good ventilation reduces health risks and costly repairs from water damage.
