What Makes a Great Bathroom Design?

A bathroom is a highly technical room. Getting it designed is not easy as it needs to meet compliance requirements, be functional in a small space, deal with humidity and air exchange requirements and yet needs to also give you the emotions you are looking for — you want a bathroom that you want to be inside!

If I were to rank it up, the most commonly overlooked decisions in the bathroom order is: layout first, storage second, fixtures third and finishes last. Get this order the wrong way around — for instance, pick tiles first then try to fit the floor plan — and you are destined to compromise your design along the way.

However, before looking into the aesthetic design and layout ideas of your bathroom, the technical aspects to note and keep in mind are the following: windowless bathrooms need to be exhaust ventilated at a minimum of 25 L/s (NCC 2022, ABCB Housing Provisions, Part 10.8) to comply with building code, and waterproofing is not optional but code mandated — we will revisit this later on. These are things that must be factored into the bathroom design. With that in mind, the most important decision that will define everything else — cost, storage, layout — is the bathroom floor plan layout. Here is how the layout ideas are being approached in Australia.

Popular Bathroom Layout Ideas for Australian Homes

Australian homes usually have three types of bathrooms: small ensuite (2 m² to 3.5 m²), family bathrooms (4 m² to 6 m²), or bath and shower combination.

The ensuite bathroom size between 2 m² and 3.5 m² leaves you no leeway — every millimetre of space counts, and a wall-hung toilet and wall-hung vanity is a must. The family bathroom layout of 4 m² to 6 m² leaves more options, just keep door swing and wet area separation in mind during the design stages.

Exploring bathroom layout ideas at the floor plan stage — well before plumbing rough-in and even demolition — is when you can save on your bathroom renovation budget. The relocation of a toilet suite or basin to another wall after piping in is an expensive exercise, so keeping plumbing on one wall at all times is probably the easiest way to contain the cost of the renovation.

With the layout decided, the next step is selecting what you build it from — the materials, fixtures and finishes you choose define how the bathroom will last over the long run as well as the overall cost.

Choosing Materials, Fixtures, and Finishes

Tile selection is the most common mistake I encounter and the one that costs the most money. Porcelain tiles are the best option for a bathroom as they do not soak up water and are available in large format 600 × 1200 mm tiles, dominating bathroom design ideas in 2025 and 2026. Ceramic tiles are a reasonable option for bathroom walls, but floor tiles must have a certain level of slip resistance — AS 4586 requires a bathroom floor to achieve a minimum P3 rating in wet conditions, which highly polished and gloss finishes rarely achieve, and therefore matte and honed tiles are the responsible specification.

Beneath all of that is waterproofing, where you should never compromise on a bathroom renovation. Shower walls must be waterproofed to a minimum height of 1800 mm (NCC 2022, ABCB Housing Provisions, Part 10.2) above the floor substrate, and bath-adjacent walls to a minimum of 150 mm above the bath rim. Waterproofing must be carried out by a licensed waterproofer applying membranes to the standard set out in AS 3740:2021.

The vanity material ranges from PVC at the budget end — genuinely waterproof and a great choice in high-moisture spaces — through MDF for the mid-range, and plywood at the top tier. CETO and Aulic are among the manufacturers that offer plywood vanities finished to a high quality that can withstand the test of time. As for tapware style, matte black remains the most popular choice, while brushed gold and gunmetal grey continue to grow in popularity as people look to introduce warmth and depth within their colour schemes.

The decisions that have the biggest effect on the overall look and feel of the bathroom — particularly in the Australian market where many bathrooms are small — are about placement. Where do you locate the vanity, and how do you do it? A corner vanity can give you so much more floor space.

Maximise Bathroom Space with a Corner Vanity

A corner vanity is a fantastic solution that many homeowners don't often think about when planning a small bathroom renovation. Situated diagonally in a corner, it can measure anywhere from 600 mm to 900 mm across the diagonal face, which gives you a lot of flexibility with the remaining wall lengths for the toilet suite and a towel rail so you don't feel like you're in a cupboard.

Corner Vanities are ideal for a powder room and small ensuite, where a typical single vanity might block your view of the room from the doorway. Placing a vanity in corner position gives the whole room a sense of flow and opens up floor area that would otherwise be lost when a square unit blocks off the whole wall. Installation does require some thought regarding plumbing rough-ins — something to discuss with your licensed plumber before you pour the slab or close up the walls.

A little bit of bathroom inspo browsing online can come in handy here, as there are plenty of pictures of beautifully installed corner vanities that give an excellent sense of scale and proportion.

Smart space planning like the corner vanity placement can also make a direct impact on your bottom line, so it is important to be mindful of all these variables against an estimated bathroom renovation budget.

Budgeting for Your Bathroom Renovation

A full bathroom renovation in Australia falls into one of three broad budgets. A budget refresh — new fixtures, tapware and tiling over existing substrate if structurally sound — runs between $8,000 and $15,000. A mid-range remodel, covering full strip-out, re-waterproofing, tiling, new vanity and fixtures, falls between $15,000 and $25,000. Large format tiles, a freestanding bath and premium custom joinery sits above $25,000 and well beyond — figures that align with what the industry is reporting more broadly. The HIA Bathroom Renovation Cost Guide 2025 puts small ensuite renovation costs at $10,000 to $25,000 (HIA Bathroom Renovation Cost Guide 2025), with Sydney and Melbourne sitting at the higher end.

Plumbing changes are the most common reason a budget blows out, and waterproofing compliance is also often underestimated. Keep the toilet, basin and shower in the same location where possible — that alone can save thousands. Relocating waste and supply lines for a retrofitted corner vanity typically adds $300 to $600 to the plumbing bill, and a mid-range bathroom renovation generally runs four to six weeks from strip-out to completion. Waterproofing is a mandatory requirement carried out by a licensed waterproofer in most Australian states and cannot be excluded.

Choosing a corner vanity over a double vanity can be one way to reduce cost without sacrificing style. Paired with a Fienza basin mixer in brushed nickel, a Covey frameless shower screen and large format tiles, you can achieve a bathroom that feels fully finished and curated within a mid-range budget. Bathroom design ideas that never lose their currency aren't about spending more — they are about spending in the right areas. Good bathroom ideas and bathroom inspo are everywhere, but the best bathroom layout ideas always start with the floor plan.

FAQs

How long does a mid-range bathroom renovation typically take from strip-out to completion?

Most mid-range bathroom renovations run four to six weeks once trades are sequenced correctly — waterproofing alone requires a mandatory cure period before tiling can begin, which accounts for several days in that timeline. Delays almost always come from late fixture deliveries or trades being rescheduled, so locking in your vanity, tapware, and shower screen before demolition starts is genuinely worth the effort.

Can a corner vanity be retrofitted into an existing bathroom, or does it only work in new builds?

A corner vanity can absolutely be retrofitted, though the plumber will need to relocate the waste and supply lines to suit the new position — budget an additional $300 to $600 for that work depending on wall construction. The earlier in your renovation planning you confirm the placement, the less disruptive and costly that adjustment will be.

What is the most common mistake homeowners make when selecting grout for large format tiles?

Choosing a grout colour that competes with the tile rather than complementing it is the most frequent misstep — wide-format tiles with tight joints generally look cleanest with a tone-matched grout that lets the tile surface read as continuous.
