Home Renovation Specialists in Melbourne
Balwyn homes have a character that’s hard to replicate in new builds. Wide hallways, high ceilings, generous room sizes, and bathrooms that were often built decades ago and never touched since. If you’re planning bathroom renovations in Balwyn, you’re likely dealing with one of two situations: an original bathroom that’s tired, cracked, or no longer functional, or a mismatched addition that doesn’t reflect the rest of the home.
We have spent 15 years working on homes across Melbourne, including Balwyn properties with the same quirks and challenges. Below, you’ll find straight answers about cost, timeframes, and what it’s like to work with a builder who manages your project personally from start to finish.
Posted on Google Tessa PozzobonTrustindex verifies that the original source of the review is Google. We had JBK Homes renovate our bathroom and separate WC at our home in Briar Hill, and we couldn't be happier with the result. Jake was fantastic to deal with from start to finish. With young children at home, he was always incredibly considerate, keeping the site clean and tidy every day and working around nap and sleep times wherever possible. His communication was excellent, and both he and his team were friendly, respectful and professional throughout the renovation. The workmanship and attention to detail were exceptional, and the finished bathroom exceeded our expectations. We wouldn't hesitate to recommend JBK Homes to anyone looking for a builder who genuinely cares about quality, communication and making the renovation process as stress-free as possible.Posted on Google Sharon KepperTrustindex verifies that the original source of the review is Google. I have used JBK Homes for several jobs and I have always found Jake to be extremely polite and pleasant to work with as is his team. Nothing is too much trouble and their standard is perfection. He has done several smaller stonework projects for me at my home in Wonga Park which have been completed to my utmost satisfaction. This includes a complete bathroom renovation which included removing all wall tiles and giving the whole bathroom a modern and fresh finish. The latest project he has done for me was a complete renovation of a 3 bedroom with 2 bathroom unit in Warranwood. The result again is amazing with attention to detail showing in every aspect of the work. This was difficult as the tenants were still living in the unit and they only had to move out for 10days in order to complete the flooring. He and his team were extremely respectful of their requirements and worked around their needs. I highly recommend JBK Homes for your next project, his pricing is very reasonable and he comes with complete honesty and openness in his planning and keeps you informed of progress along the way.Posted on Google Joshua NaveTrustindex verifies that the original source of the review is Google. We contacted Jake at JBK for our home renovation in Greensborough. Jake was originally contracted for the carpentry work, though not only was the work fantastic but Jake also took initiative to manage trades on site and offer advice on improvements. For any of our projects we will be using JBK/Jake again.Posted on Google Sarah SavioTrustindex verifies that the original source of the review is Google. Jake has been amazing to deal with not just for our project but for clients of mine that I refer. The one stand out (besides his craftsmanship) was his communication. I received a generous amount of updates throughout the progress which was handy & he provided recommendations along the way with good justification for long term durability. Look forward to our next project with JBK Homes.Posted on Google Robert KirkbyTrustindex verifies that the original source of the review is Google. Jake did a number of fix up carpentry and joinery jobs on our home. He and his assistant were knowledgeable, efficient and straightforward to work with. We are happy with the quality of the work and the overall outcome.Posted on Google NickTrustindex verifies that the original source of the review is Google. Jake and the JBK Homes team were outstanding from start to finish. We did a major renovation to our family home. Jake is a fantastic builder, leader and organiser with extensive trade experience who brings great ideas to every project. His craftsmanship and attention to detail are second to none. Our outdoor entertaining area, custom BBQ, decking, steel doors and concrete-look render exceeded our expectations and were completed on time. Jake and the entire team were an absolute pleasure to deal with, with a special mention to Dan, whose professionalism and workmanship were exceptional. Jake always answered my calls and whether it was after hours or on weekends, his customer service was outstanding. I would not hesitate to recommend JBK Homes. I didn't know Jake or his team personally before the project but I would be more than happy for any prospective client to contact me directly if need be.Posted on Google Tony GiannopoulosTrustindex verifies that the original source of the review is Google. We engaged JBK Homes to complete a large extention and renovation to our home and we were extremely happy with both the process and the finished result. Jake was professional and took genuine pride in his work. His attention to detail and workmanship were outstanding and he always made the time to discuss ideas and work through any challenges as the project progressed. Nothing was ever too much trouble. The quality of the work was exceptional, communication was always clear and it was obvious that Jake genuinely cared about achieving the best possible outcome rather than simply getting the job finished. We have no hesitation in recommending JBK Homes to anyone looking for a builder for an extension or renovation. Jake is honest, hardworking and delivers a quality result.Posted on Google CaitlynTrustindex verifies that the original source of the review is Google. We recently had a bathroom and WIR built by Jake and couldn’t be happier with the result. From the very beginning, Jake was incredibly thorough - everything was clearly explained and quoted properly, so there were no surprise costs along the way. The whole process was organised and stress-free with Jake overseeing everything. All the trades Jake brought in were excellent - reliable and the quality of work was fantastic across the board. We were so stoked to find a builder who is this detailed and transparent from the start. Couldn’t recommend JBK Homes any higher!Posted on Google Megan SkinnerTrustindex verifies that the original source of the review is Google. Absolutely fantastic experience! From day one, everything that was promised was delivered. The turnaround time was incredibly fast without compromising on quality. Super easy to deal with, kept me updated all the way through, and the end result is better than I imagined... Highly recommend!Posted on Google Simone TindallTrustindex verifies that the original source of the review is Google. I had 3 people quote for the replacement of a deck on a flat roof and Jake (JBK Homes) quickly became the obvious choice. It was his professionalism and clear communication that was so impressive and helpful. As we didn't know the state of the sub floor and the water proofing situation, there were unknowns. Jake was very transparent and detailed the unknowns and provided best case and worst case and scenarios. Jake was onsite for the whole job with two other quality tradesman, qualified carpenters. Great consideration was given to our family, tidying up each day and a detailed site clean when the job was complete. The result is terrific, couldn't be happier. Quality workman ship and great attention to detail. I would highly recommend Jake and his team, for extensions, renovations and the smaller jobs. I wish I'd known Jake (JBK Homes) when I had my Hampton Californian Bungalow, he would have done a beautiful job there.
Balwyn’s housing stock is genuinely mixed. You’ll find California bungalows, Federation homes with high ceilings and original detailing, and many brick-veneer homes. Each type brings its own bathroom problems.
Older homes often have plumbing stacks that were never designed for modern fixtures like double vanities or rainfall showers. Waterproofing membranes from decades ago have usually failed or were never installed to today’s standard, which is why you sometimes see damp patches on ceilings below upstairs bathrooms. Layouts can also be awkward, particularly where a laundry or toilet was added later, and the space was never planned as a whole.
We’ve worked in enough of these homes to know what’s usually hiding behind the tiles before we even start. That experience means fewer surprises once demolition begins, and a quote that holds up rather than blowing out halfway through.
Some pockets of Balwyn fall within a heritage overlay through the local council. For most bathroom renovations, this only becomes relevant if you’re changing the home’s exterior appearance, such as adding a window or altering the roofline. Internal work such as retiling, replumbing, or reconfiguring a layout usually falls outside heritage requirements, but not always.
Boroondara applies internal alteration controls to some properties, as specified in the Schedule to the Heritage Overlay for that address, and where this applies, internal changes require approval. It’s worth checking your property’s specific schedule before finalising a design, or we can check this for you as part of the planning stage.
Where a permit is needed, we handle the application and manage the process so you’re not left chasing council paperwork on top of everything else.






Most homeowners contacting a builder for the first time aren’t looking for the flashiest pitch. They want someone who answers the phone, turns up when they say they will, and gives a straight answer when something changes on site. That’s the standard we work to.
Every project is overseen directly from the first conversation through to handover. There’s no rotating cast of project managers or a sales team that disappears once the contract is signed. You deal with the same person throughout, which makes a real difference when decisions need to be made quickly during construction.
We also work with a small, consistent team of trades we’ve used for years. That consistency shows up in the finish. Tiling, waterproofing, and cabinetry are done by people who know our standards, not whoever happened to be available that week.
A full renovation covers everything from plumbing and electrical relocation through to tiling, waterproofing, cabinetry, and fixtures. This is the right option when the layout no longer suits how your family lives, or when the existing bathroom has underlying issues that need fixing properly rather than patched over.
Ensuites often deal with tighter footprints and shared walls with a bedroom, which changes how we approach ventilation and noise. We design ensuites that make the most of a smaller space without feeling cramped, using layout changes rather than just cosmetic updates.
Not every bathroom needs a full rebuild. Sometimes a smarter layout, better storage, and updated fixtures solve the problem without touching plumbing or structure. These projects are quicker and more budget-friendly, and we’re upfront when a smaller scope is genuinely the better option for your situation.
If you want your bathroom to feel like it genuinely belongs to the house rather than something bolted on afterwards, this is where custom joinery, stone benchtops, freestanding baths, and tiling choices matched to the home’s character come into play. This work takes longer and costs more, and we’ll be clear about that from the outset.
The first step is a proper conversation about what’s not working in your current bathroom and what you want instead. From there, we move into design, where layout, fixtures, and finishes are locked in before any pricing is finalised. This order matters. Pricing a job before the design is settled is one of the main reasons renovations run over budget.
Once the design is approved, we put together a clear written contract using HIA documentation, so you know exactly what’s included and what happens if anything changes along the way. Any variation during construction is documented and approved by you before work proceeds, rather than appearing as a surprise on the final invoice.
Construction follows a set sequence: demolition, rough-in plumbing and electrical, waterproofing, tiling, then fixtures and cabinetry. We check waterproofing against Australian Standards before tiling begins, because this is the step that causes the most long-term problems when rushed.
Handover includes a walkthrough of the finished bathroom and a structural warranty in line with Victorian building regulations, so you have documented cover after the job is complete.
Cost depends on scope, not just size. A cosmetic update to an existing layout costs less than a full renovation that repositions plumbing or corrects structural issues in an older home. Waterproofing rectification on a period property, for example, adds cost that a newer home simply doesn’t need.
Fixture and finish selection also plays a large part. Standard tiling and fittings sit at one end of the range, while custom stone, freestanding baths, and imported fixtures sit at the other. We provide a fixed price once your design and selections are locked in, rather than a rough estimate that changes once work begins. This upfront approach is part of why our clients rarely deal with unexpected variations partway through.
Most bathroom renovations in Balwyn take between four and eight weeks on site, depending on scope and whether structural or plumbing changes are involved. Older homes can add time if unexpected issues turn up once walls or floors are opened, which happens more often in period properties than in newer builds.
You can usually stay living in the home during the renovation, particularly if you have a second bathroom available. We’ll talk through what to expect week by week so there are no surprises about noise, access, or timing.
I’ve been building and renovating homes across Melbourne for 15 years, with a good number of those projects in Balwyn and the surrounding suburbs. I’m a licensed builder and fully insured, and Domestic Building Insurance is arranged wherever a project requires it under Victorian regulations.
I still oversee every job personally rather than stepping back once a contract is signed. That’s a deliberate choice. Renovations go more smoothly when the person managing the job on paper is the same person you can call when something needs a decision on site.

If you’re planning bathroom renovations in Balwyn and want a straightforward conversation about layout, cost, and timing, get in touch for a free quote. You’ll speak directly with the builder managing your project, not a call centre or sales rep.
Alongside Balwyn, we regularly work on bathroom renovations in Camberwell, Kew, Surrey Hills, Canterbury, and Box Hill. These suburbs share much of the same housing character, so the same issues with older plumbing, heritage considerations, and period layouts apply just as much there.
Failed waterproofing, undersized plumbing stacks, and layouts shaped by later additions rather than original design are the most common issues we find once work begins.
In most cases, yes, particularly if you have access to a second bathroom. We'll set out what to expect during each stage so you can plan around it.
Any issue is documented, priced, and approved by you before work proceeds. You won't see anything on the final invoice that you haven't already approved along the way.
We provide a fixed price once your design and fixture selections are finalised, which is what allows us to avoid the variation blowouts that catch a lot of homeowners out.
