Let’s get started!

Constructing a Shower Hob: A Foundation for Success

Before you start laying tiles, your tiling project needs a stable, water-managed base - and that begins with creating a shower hob.

A shower hob helps to:

• Direct water flow towards the drain
• Keep wet areas contained
• Support later tile layers without sagging or instability

Building a shower hob should take place immediately after priming but before you waterproof. Follow these instructions for a step-by-step guide for this important task:

1. Choose the size of your new shower within the space, then measure and mark the hob position on the floor using a straight edge. Make sure to double check your measurements and that everything is square (hint: measure diagonally from corner to corner)!

2. Form the hob using lightweight Hebel blocks and secure in place with a cement-based mix, pressing them firmly along your marked lines and joining the ends so the hob feels solid and level. Clean any excess mix from around the blocks before it sets.

3. Mark the fall of the hob towards the drain then screed the base. Australian standards recommend a minimum fall of 10mm for every 600 mm to ensure proper drainage.

4. To create the shower base, mix the screed until it holds together when squeezed in your hand. Spread it evenly across the floor, building up the surface and following your fall markings. Use a level to smooth everything out as you go. Prioritising a clean work surface and level workmanship at every stage will lead to the best result for your beautiful new bathroom.

5. Once the screed has fully dried, sweep the area clean and apply primer again. Finish by sealing all internal corners - this includes the walls, floor and the hob itself - with a neutral cure silicone, ready for waterproofing and tiling.

The secure base of the shower hob is now complete and, once set, will become the canvas to tile a bathroom with confidence.

Waterproofing A Bathroom: Protection Before Tiles

When learning how to tile a bathroom, waterproofing is one of the most critical steps. Leaving it out or cutting corners risks water damage and costly repairs later.

Here’s what waterproofing involves:

Clean & Level

Before you apply any products, make sure all surfaces are clean of dust, paint and old adhesive from previous products. Ensure also that the surfaces are level and solid, to set the stage for strong adhesion and a long-lasting finish. Learn more about our screed and levelling compounds and ensure you set the right foundation.

Waterproof*

Apply a high-quality waterproofing membrane and primer to all bathroom walls, bathroom floor, and shower areas. Ensure you check corners and joints thoroughly to prevent moisture from travelling where you least expect it! Our waterproofing materials create a protective shield that lets you install tiles with confidence.

Laying Bathroom Tiles: Design Meets Craft

Now comes the exciting part - bringing your design to life! This is where tiling a bathroom becomes both an art and a skilled task.

Planning & Layout

Remember that planning is an essential part of the process, so before any adhesive hits the walls or the floor, dry-lay your tiles and admire your new bathroom’s potential aesthetic.

Then, establish your starting point (often the shower or vanity wall) and work out how the patterns will flow across the bathroom tile surfaces. Balance cut pieces throughout the room so that your design feels intentional and considered. A thoughtful layout makes all the difference in creating harmonious bathroom tiling.

Mix Adhesive, Spread & Set Tiles

Be sure to follow the manufacturer’s instructions to accurately mix the adhesive. The right consistency will help tiles bond properly and prevent slipping or hollow sounds post-installation.

Spread the adhesive using a notched trowel in an even and controlled motion. Keep adhesive sections small so that the product doesn’t dry before the tiles are set in place.

Finally, press your chosen bathroom tiles into place using spacers for even grout lines. Make sure each tile sits flat and level, and that you check the alignment of the lines continually as you work.

This process of mixing, spreading and setting tiles methodically ensures that your beautiful bathroom remains functional and long-lasting, as well as aesthetically pleasing. Browsing our high quality tile adhesives is the perfect way to get started on this part of the process.

Grouting & Finishing: The Final Flourish

Once your tiles are secured, it’s time to bring it all together with finishing touches that elevate your desired look and protect its long-term performance.

Allow the adhesive to fully set, adhering to the packaging for specific drying times.

Next, mix and apply the grout with a float, pressing it firmly into the joints between tiles. Choose a hue that enhances your design and complements the chosen colour of your bathroom tiles.

As always, clean the surface frequently by using a slightly damp sponge to remove any excess grout while it’s still fresh. Then ensure a quality seal around the edge and grout lines to strengthen the resistance to water - especially in wet areas such as the shower or around the bathtub.

Our grout comes in a range of different colours to complement any desired finish.

Design Tips to Tile a Bathroom

Good technique matters - but so too does vision. Here are a few design thoughts that make your tiling experience feel inspired and intentional:

Mix Textures and Tones

You don’t always have to match wall and floor tiles. Contrasting textures can add depth - like a glossy subway tile with a matt porcelain floor tile - to create visual interest.

Think About Scale

Large format floor tiles can make small spaces feel bigger, while small mosaics are perfect for feature areas or shower niches.

Consider Placement

Tiles behind a vanity or around a bathtub often act like design anchors. Planning these focal points early can help your tiling project in the bathroom feel intentional and balanced.

Key Reminders for a Successful Bathroom Renovation

A well-executed bathroom renovation isn’t just about choosing beautiful tiles - it’s about planning carefully, working methodically, and making smart decisions that will stand the test of time. Perhaps this may include considering the longevity of the design choices, or ensuring that all your tiling in the bathroom is of the best quality available.

Whether you’re tackling a full DIY project or working alongside professionals, these key reminders will help your bathroom renovation run smoothly and deliver results you’ll love:

Plan Before You Start

Rushing into demolition or tile selection can lead to costly mistakes. The old saying states to measure twice, cut once. For your bathroom tiling, this means to finalise your layout and tile choices early to have a solid plan and design. Then measure accurately, and allow extra tiles for cuts and wastage. You don’t want to find yourself one tile short! Also, consider how the space will be used day to day by your family - bathrooms can be a haven for one person and a practical space for another. Good planning creates clarity throughout the renovation.

Prepare Surfaces Properly

Strong results start beneath the shiny surface of your new tiles. Always clean and level the walls and floors regularly throughout the renovation. Repairs any cracks or uneven areas if they arise, or are a result of previous work, to ensure the best result. Prime surfaces correctly, following manufacturer’s instructions before waterproofing or tiling. Skipping preparation can compromise even the most beautiful bathroom design.

Choose Quality Materials

Tiling in bathrooms is invaluable to the success of your DIY bathroom project. However, these spaces experience daily moisture, heat and foot traffic that demand high quality materials in order to stand the test of time. Invest in durable tiles suitable for walls and bathroom floors, slip-resistant flooring for safety and reliable adhesives, grouts and sealants. Quality materials combine the strength of durability with the aesthetics of the beautiful bathroom renovation of your dreams.

Your Bathroom is A Space Worth Crafting Well

Learning how to tile a bathroom isn’t just about technique, tools and trades. It’s about shaping a space to feel serene and truly individual. From practical steps like grouting and laying tiles, to creative decisions on design and texture, this process invites you to imagine your ideal oasis and bring it to life.

Even if you’ve never laid a tile before, through thoughtful preparation, the right tools and an inspiring palette of tiles, your DIY bathroom tiling project can be an achievable and rewarding experience that results in a stunning space for your family.

While tiling your own bathroom can save money, it’s not a small undertaking. If it’s starting to feel like more than you bargained for, consider engaging a licensed tradie through Hipages to make sure the job is completed correctly the first time.

*A Note About Waterproofing

This guide is here to inspire confidence and creativity as you transform your space, but bathrooms are wet areas where precision matters. Mistakes with waterproofing, surface prep or installation can lead to leaks, mould, tile failure and costly repairs — and in many parts of Australia, wet-area work must meet building standards. Waterproofing, in particular, may not be able to be completed as a DIY project and instead you may need a licensed professional to assist with this task in order to meet your state compliance and approvals process.

Use this content for general guidance only. If you’re ever unsure — especially about waterproofing or compliance with local codes — we recommend checking with a licensed professional before you begin. Your home deserves to be both beautiful and built to last.
