As a result, bathrooms remain one of the two most popular rooms to renovate as more Melburnians stay put and upgrade rather than relocate.. Small bathrooms pose a unique challenge: you need to maximise function and storage without making the room feel cramped. This guide explains how to plan a smart renovation, highlights current trends and cost ranges, and offers space‑saving ideas specific to Melbourne’s housing stock. By the end you’ll know how to create a stylish, efficient small bathroom that boosts daily comfort and resale potential.
1 | Why renovate a small bathroom?
Lifestyle and market drivers
Homeowners renovate bathrooms to update the style of their property and improve comfort. Smaller spaces require extra creativity, yet the payoff can be substantial; a well‑designed small bathroom enhances liveability and increases resale appeal. According to a 2024 home‑renovation survey, over 30 % of Australians budget between $5 000 and $15 000 for their projects, so improvements don’t have to break the bank. Moreover, the most popular rooms to renovate are kitchens and bathrooms, showing that buyers value these spaces.
Typical cost ranges
First, set a realistic budget by understanding local cost ranges. In Melbourne, small bathroom makeovers typically start at $10,000–$15,000. By comparison, a full-service renovation often sits around $25,000–$30,000 or more. To stay on budget, keep plumbing in the same location and choose mid-range finishes. Conversely, relocating plumbing or adding custom joinery pushes costs higher.
2 | Planning your renovation
Define goals and budget
Before tearing out tiles, decide why you’re renovating. Are you aiming to increase property value, improve functionality or both? Once the goal is clear, set a budget. A Melbourne bathroom remodel might cost as little as $10 500 according to industry estimates; however, if you anticipate structural changes or premium finishes, allocate more and include a 10 % contingency for surprises. Also consider whether you need professional help or plan some tasks yourself.
Plan layout and design
For small bathrooms, every centimetre counts. Sketch multiple layouts or hire a designer to explore options like floating vanities, walk‑in showers and pocket doors. On their blog, HBK recommends using shelves above the sink to create storage and mirrors to increase light. First, use a minimalist layout to make the room feel larger. In addition, plan lighting carefully so the space doesn’t feel cave like. Ideally, bring in natural light with skylights or high windows. Otherwise, add dimmable LED strip lighting.
Choose materials and fixtures
Select materials that suit your style and size. For a modern look, use glass and stainless steel; for a warmer feel, choose timber and stone. Space‑saving fixtures such as compact toilets, wall‑hung vanities and frameless shower screens open up the floor. If you crave luxury, consider spa‑like elements such as soaking tubs and steam showers-one of the top 2025 bathroom trends, but ensure the scale suits your room.
Hire licensed professionals
Unless you’re a seasoned DIYer, engage licensed builders, plumbers and electricians. Checking credentials and obtaining multiple quotes ensures value. For Melbourne renovations, confirm that your contractor holds a domestic building licence and is registered with the Victorian Building Authority. Major structural changes or work that alters plumbing or electrical systems generally requires a building permit, so consult your local council or a building surveyor before commencing.
Plan for the unexpected
Even with careful planning, hidden water damage or old wiring may increase costs. Set aside contingency funds and allow extra time in your schedule. A clear plan and experienced tradespeople help keep the project on track.
3 | Design ideas & space‑saving solutions
Smart storage and layout
HBK’s article “Bathroom Remodel Ideas for a Small Space” offers many practical ideas. They suggest using open shelves above the sink to free floor space and adding mirrors to reflect light. Installing ceiling‑mounted towel bars and overhead mirrors with storage helps clear walls and counters. Under‑sink cabinets with sliding drawers hide clutter and improve accessibility. Each of these solutions maximises storage without crowding the room.
2025 design trends for small spaces
Emerging trends can inspire small bathroom makeovers. The Shower Company’s 2025 design report highlights six themes:
- Spa‑like bathrooms – steam showers and soaking tubs create wellness retreats.
- Smart technology – touchless faucets, smart mirrors and energy‑efficient fixtures enhance hygiene and convenience.
- Bold colours and textures – jewel tones and fluted tiles add drama.
- Nature-inspired elements – wooden vanities, stone basins and indoor plants introduce biophilic design.
- Minimalism with flair – floating vanities and statement lighting combine function and style.
- Sustainable materials – low‑flow fixtures and recycled tiles support eco‑friendly living.
For small bathrooms, incorporate these trends judiciously: a floating vanity, a bold accent wall or a touch‑free faucet can deliver impact without overwhelming the space.
Space‑efficient fixtures
- Walk‑in showers: A frameless screen and linear drain create an open feel and are accessible for all ages.
- Compact bathtubs: Choose deep, narrow soaking tubs rather than full-length baths.
- Corner basins and toilets: Installing fixtures in corners frees up floor area.
- Pocket or barn doors: Sliding doors save the swing space of hinged doors.
4 | Budgeting and cost‑saving tips
- Reuse existing plumbing locations. Moving pipes adds significant cost; keeping fixtures in place saves thousands.
- Mix high and low finishes. Invest in quality taps and shower hardware but use affordable large‑format porcelain tiles for a high‑end look at a mid‑range price.
- DIY cosmetic updates. Painting walls, refinishing cabinet fronts or installing open shelving can refresh a bathroom without major expense.
- Plan purchasing. Order fixtures and tiles early to avoid delays and price spikes.
According to the 2024 renovation survey, many Australians encountered unexpected expenses-almost three‑quarters cited financial issues as the biggest barrier. To avoid overcapitalising, set a firm budget and allocate at least 10 % for contingency
5 | Navigating permits and local considerations
Victorian regulations require building permits for renovations involving structural changes or alterations to plumbing and electrical systems. Minor cosmetic updates—like replacing tiles or installing a new vanity—usually don’t need a permit. However, because each council interprets the Building Regulations differently, always check with your local council or a registered building surveyor. Hiring licensed tradespeople ensures compliance with building codes and plumbing standards.
In heritage-listed properties common across Melbourne’s inner suburbs, additional planning permits may be necessary. Early consultation with the council will prevent costly mistakes.
Conclusion and next steps
Renovating a small bathroom in Melbourne doesn’t have to be intimidating. By defining clear goals, planning layouts carefully, selecting space‑saving fixtures and staying on top of budget and permits, you can transform a cramped room into a functional, stylish oasis. Use design trends sparingly, focusing on elements that enhance comfort and sustainability.
