Our Essential Guide for Expertly Planning Your Bathroom Addition Inner West
Planning a successful bathroom addition involves meticulous preparation and thoughtful decision-making. Whether you’re undertaking a budget bathroom renovation or investing in a
premium bathroom renovation, a structured approach ensures your project runs smoothly, stays within budget, and meets your exact requirements. Here’s our expert step-by-step guide to planning your bathroom addition:
STEP 1
Define Your Goals and Budget
Clearly define what you want from your new bathroom addition—whether it’s a practical extra bathroom for guests or a luxury retreat featuring luxury elements such as underfloor heating and heated towel rails. Understand your financial limits by researching the average bathroom renovation cost in the Inner West. Costs can vary widely depending on the materials, labour costs, and complexity of the installation process.
STEP 2
Evaluate Available Space
Measure precisely how much space you have. Whether converting an existing space or building an extension, accurate measurements (in square meters) will help determine what’s feasible, from a compact small bathroom to a spacious large bathroom.
STEP 3
Initial Design and Layout
Work closely with our
experienced interior designer to create your perfect bathroom layout. This stage involves deciding the position of your shower, bathtub, sink, and toilet, as well as considering essential fixtures like shower screens and stylish porcelain tiles.
STEP 4
Assess Plumbing and Electrical Requirements
Review your existing plumbing and electrical setup. The cost for electrical work and new plumbing can fluctuate depending on complexity. Ensuring these are professionally planned and executed is critical for compliance and safety.
STEP 5
Council Approval and Necessary Permits
Obtain any necessary permits, including planning permission and council approval, especially when significant structural work or external additions like an outdoor bathroom are involved.
STEP 6
Selection of Fixtures and Finishes
Choose your fixtures and finishes—such as matte black tapware, durable tiles, and modern extractor fans. Remember, these choices will significantly impact your overall cost and your project’s aesthetics.
STEP 7
Waterproofing and Preparation
A critical stage involves hiring a licensed waterproofer to ensure your bathroom is appropriately sealed. Professional waterproofing prevents future damage, adding longevity and peace of mind.
STEP 8
Construction and Final Installation
This stage includes the professionally installed new tiles, heated towel rails, sink, toilet, and other selected features. The hourly rate for trades may vary, and the duration can fluctuate depending on the project’s complexity.
Proficiently Managing Necessary Permits and Inner West Council Regulations
Navigating permits and council regulations can be one of the more daunting aspects of undertaking bathroom renovations in Inner West. Each local council has specific rules governing alterations, especially for projects involving plumbing, structural changes, or significant room expansions. Typically, full renovation projects involving significant changes to your house structure or additional plumbing require detailed applications for approval.
Inner West Home Extensions has extensive experience handling local permitting processes, ensuring your new bathroom complies fully with all regulations. We assist homeowners by clearly outlining required documentation and fees, ensuring everything from your new toilet placement to the installation of essential features like an extractor fan is fully compliant. Permits can vary depending on your project's scope, including adjustments to walls, floors, and plumbing arrangements. Our experts streamline this complex process, ensuring easy access to accurate information and timely approvals, so your renovation can proceed without unnecessary delays.
Estimating Bathroom Renovation Costs and Managing Your Budget
In Sydney’s Inner West, the cost of a bathroom extension typically ranges from $30,000 to over $80,000, depending on the scope of work, design complexity, and condition of the existing structure. While cosmetic renovations may be more affordable, extending or relocating a bathroom—especially in older homes—requires careful planning and professional execution to avoid unexpected costs.
Key cost drivers include structural changes, waterproofing, plumbing relocation, ventilation upgrades, and high-quality finishes. Custom cabinetry, premium tiles, and underfloor heating will raise the price, while smart choices in layout and materials can help manage your budget without compromising on aesthetics. Older homes often present hidden costs such as subfloor repairs or outdated pipework that needs upgrading to meet modern standards.
To keep your project financially on track, start with a detailed consultation and a transparent cost breakdown. This allows you to prioritise features, identify opportunities for cost savings, and avoid budget blowouts.
Our team offers expert guidance tailored to Inner West conditions and heritage requirements, helping you make informed decisions at every stage of the process.
Types of Bathroom Additions We Build in the Inner West
Every home and family is different, which is why we offer a range of bathroom extension solutions tailored to Inner West properties—from heritage terraces to modern duplexes. Here are the most popular types of bathroom additions we design and build.
Ensuite Additions
Perfect for adding privacy and convenience to the master bedroom. An ensuite bathroom increases daily comfort and adds serious resale value, especially in family homes or shared living situations.
Second Bathroom or Family Bathroom
Many older Inner West homes only have one bathroom. Adding a second bathroom—whether upstairs or as part of a rear extension—improves livability and is highly appealing to buyers with children or guests.
Powder Room or Guest Toilet
Ideal for small homes or those with frequent visitors, a powder room can be added under stairs, near the entry, or beside living areas. These compact additions are cost-effective and can be designed with high-impact finishes for a luxurious feel.
Combined Bathroom & Laundry
For homes with limited floor space, a combined bathroom and laundry offers a practical layout that still feels spacious. With smart design, you can conceal laundry appliances while keeping the room stylish and functional.
Upstairs Bathroom Additions
If your Inner West terrace or duplex already has an upper floor, adding a bathroom upstairs makes daily routines more efficient—especially in busy households. We manage all structural, plumbing, and DA requirements to make the addition seamless.

Frequently Asked Questions About Bathroom Addition
1. How much does a bathroom extension cost in the Inner West?
The cost of a bathroom extension in the Inner West typically starts from $30,000 for a small or basic build and can exceed $80,000 for a high-end or custom design. Costs depend on several factors including the size of the extension, the level of structural changes required, the complexity of plumbing reroutes, waterproofing, tile selection, and fittings. Older homes in the Inner West often require updates to existing services and compliance with stricter waterproofing and ventilation standards, which can add to the overall cost. Additional expenses may also arise if the extension involves excavation or building close to property boundaries, which can require special approvals.
2. Do I need council approval for a bathroom extension?
In some cases, bathroom extensions may be carried out under a Complying Development Certificate (CDC), which is a fast-tracked approval process. However, many properties in the Inner West fall within heritage conservation zones or have unique zoning constraints, making a Development Application (DA) through your local council necessary. If the proposed extension alters the external structure, affects overshadowing, or is visible from the street, you will almost certainly need a DA. Heritage homes in suburbs such as Newtown, Dulwich Hill, Balmain, or Ashfield are especially subject to strict controls, and it’s important to work with a builder familiar with the local approval process to avoid delays.
3. How long does a bathroom extension usually take?
The construction of a bathroom extension generally takes between 6 to 10 weeks once work begins on site. This includes demolition, framing, waterproofing, plumbing, electrical, tiling, and final fittings. If a DA is required, you should allow an additional 2 to 3 months for design, council submission, and approvals. Projects in tight Inner West streets or terraces may also take longer due to limited site access or staging areas. Weather, material delays, and custom product lead times can also impact the schedule, so it’s wise to build in a contingency buffer when planning your renovation timeline.
4. Can a bathroom extension add value to my property?
Yes, a well-designed bathroom extension can significantly increase both the functionality and value of your Inner West property. Additional bathrooms—particularly ensuites or extra full bathrooms—are in high demand among home buyers, especially in multi-storey terrace homes or older properties with limited existing amenities. Renovated bathrooms with modern finishes, efficient layouts, and quality fixtures not only make day-to-day life more comfortable but also contribute to strong resale appeal. Homes with more than one functional bathroom consistently achieve higher sale prices in competitive Inner West suburbs.
5. What are the most common challenges with bathroom extensions in heritage homes?
Extending a bathroom in a heritage-listed or conservation zone home presents several unique challenges. These include strict rules around altering the external façade, limitations on visible rooflines, and requirements to use materials and finishes sympathetic to the original architecture. In many Inner West homes, the layout may be narrow or irregular, requiring clever design to incorporate adequate ventilation, natural light, and compliant ceiling heights. Additionally, many older homes have outdated plumbing or uneven subfloors, which may need to be upgraded or levelled before modern waterproofing and tiling can be applied. Experienced builders familiar with Inner West conditions can help navigate these constraints while still delivering a high-quality finish.
6. Can I stay in the house while the bathroom extension is being built?
It is usually possible to remain in your home during a bathroom extension, but it depends on the scope of work and how many functional bathrooms you have. If the extension involves renovating your only bathroom or affects water supply and drainage throughout the home, you may need to arrange short-term alternative accommodation or temporary bathroom facilities. Construction noise, dust, and disruptions to daily routines are also factors to consider, especially if the build is taking place near bedrooms or main living spaces. Clear communication with your builder about the project timeline and daily access requirements will help minimise inconvenience during the construction period.
7. How do I choose the right builder for a bathroom extension in the Inner West?
Choosing a builder with specific experience in bathroom extensions and Inner West properties is critical. Look for a builder who understands the local council regulations, heritage overlays, and the common structural challenges of older homes. They should have a portfolio of completed bathroom extensions in suburbs like Leichhardt, Marrickville, or Stanmore, and ideally offer both design and construction services to streamline approvals. Ask for detailed quotes, check client reviews, and ensure they provide fixed pricing and guaranteed timelines. Working with a builder who manages the entire process—from planning and approvals through to final handover—can save you time, money, and stress.
