Planning bathroom renovations in Melbourne? Monarc Building Co helps homeowners create bathrooms that are practical, comfortable and finished to a high standard. With more than 10 years of hands-on experience, our Melbourne-based renovation team focuses on quality workmanship, clear communication and renovations built to last.
An outdated or impractical bathroom can affect your everyday routine. Renovating provides an opportunity to improve the space and create a bathroom that better suits your household. Whether you are planning an update or a complete transformation, we focus on understanding your requirements before the renovation begins.
That starts with a conversation about how the room is used. A busy family bathroom needs durable surfaces, generous storage and an easy-to-clean layout, while an ensuite might call for a walk-in shower, a double vanity or a freestanding bath. We take the time to understand your routine so the finished bathroom works as well as it looks.
From there, we help you plan the layout, select tiles, tapware and fixtures, and decide on lighting and ventilation. If you’re unsure what’s possible in your space, we’ll talk you through the options honestly and recommend what will make the biggest difference for your budget.
We renovate bathrooms of all sizes, from compact powder rooms and ensuites to large family bathrooms. No matter the size of the space, the same care goes into the planning, the waterproofing and the finish.

Our philosophy is simple: get the renovation done properly from the start. We provide clear timelines and communication throughout the project while maintaining attention to workmanship and finishing details. High-quality finishes and avoiding shortcuts are important to our approach.
Alongside bathroom renovations, we also provide kitchen and full home renovations. This makes Monarc Building Co a suitable choice if you are planning several improvements throughout your Melbourne property.
You’ll have one point of contact from start to finish. Jaan keeps you informed as each stage progresses, from strip-out and rough-in to waterproofing, tiling and fit-off, so you always know what is happening and when your bathroom will be ready to use.
We also understand that a bathroom renovation happens inside your home. We protect the surrounding areas, keep the site clean and tidy each day, and work efficiently to keep disruption to your household to a minimum.
Once everything is complete, we walk through the finished bathroom with you to make sure every detail meets the standard we promised. It’s the final step in a process designed to leave you with a bathroom you’ll enjoy for years to come.

We focus on practical renovation solutions that suit your existing space and requirements. From planning through to completion, our priority is quality workmanship and a finished bathroom designed for everyday use.
The parts of a bathroom you can’t see matter just as much as the parts you can. Correct falls to the waste, compliant waterproofing and careful preparation behind the tiles are what keep a bathroom performing for years. We never rush these stages, because getting them right is what makes a renovation last.
On the surface, we pay close attention to tile setout, grout lines, silicone joins and the alignment of fixtures and glass. Whether it’s a frameless shower screen, a custom floating vanity, built-in niches or feature lighting, every element is installed with care and finished to a high standard.
The result is a clean, modern bathroom that feels good to use every day, with finishes that are made to last and a layout that suits the way your household lives.

A few things homeowners usually ask before getting started.
Timelines depend on the complexity of the design, custom fixture availability and structural requirements. Essential stages, such as proper waterproofing membrane curing and precise tiling, require specific drying times to ensure long-term durability. We provide a projected schedule before starting work, so you know what to expect.
Waterproofing is a vital phase of our process. All waterproofing is installed by qualified applicators using high-grade materials applied strictly in accordance with Australian Standards (AS 3740), ensuring your space remains completely watertight.
Absolutely. Making the most of the available space is a key focus of our designs. We use smart layout techniques, such as wall-hung vanities, frameless glass, tailored niches and strategic lighting, to maximise usable space and elevate the look of compact rooms.
You have complete flexibility. We can guide you through recommended supplier showrooms to select quality tiles, tapware and fixtures, or we can expertly install items you have selected independently, provided they meet Australian plumbing standards.
