A granny flat bathroom renovator with great reviews

Genuine reviews from our raving clients who love their new bathrooms

Small bathroom & laundry, strongly recommend. Dylan and his team converted our laundry into a small bathroom, and converted the backyard toilet into a laundry. Communication, problem solving (surprises of older houses!) and scheduling were outstanding. Dylan was super helpful in engineering a solution that we could use our washing machine during the construction time, which was really important. We're thrilled with the result, thank you Dylan and team!
Dylan and his team just finished renovating our bathroom and we are thrilled with the results. Every trade delivered really high quality work and the bathroom is clean, fresh and functional now.

Dylan was flexible, considerate, and efficient. Everything ran smoothly, on budget and to schedule. Dylan even installed a new door at the last minute, which was not in the original plan.

I highly recommend Passion Built!
Dylan and his team did a perfect job. You can see he’s built my dream bathroom to the highest of specs and with an amazing eye to details. I found him on the internet and wasn’t a personal connexion but he was so professional from quote, to reference and throughout the whole project.

His pricing was competitive too. I left to Europe while the work was being done. It went without any issue and I came back to a beautiful bathroom in a clean house.

His team went above and beyond. For instance I thought the spot lights were too “cool” and his team came to change it to a warmer colour to make sure I was 100% happy.

Dylan is a great communicator, a nice person to deal with and someone who has delivered to high expectations. I recommend.
We just completed a full bathroom laundry renovation with Passion Built that required some structural changes and are extremely pleased with the end result. Old houses come with problems but nothing was too hard for Dylan & his team who worked through each issue making it a stress free experience.

The communication was excellent with regular project updates & the quality of workmanship was outstanding, they even redid some things that weren't up to standard. We absolutely love our new laundry & bathroom area so would highly recommend Passion Built if you are looking for good quality at a reasonable price they simply are the best!

Renovating a bathroom in a granny flat in offers a unique opportunity to blend modern design with functional practicality. The key to a successful granny flat bathroom renovation lies in the clever use of space, ensuring that it’s both accessible and aesthetically pleasing.

Modern bathrooms in granny flats can be customised to suit specific needs without compromising on style. For instance, walk-in showers with flat entry points are not only trendy but also practical, especially for elderly occupants. These showers can be equipped with handrails and non-slip tiles for added safety. Moreover, the installation of higher toilets and vanities can provide better comfort and accessibility.

In terms of design, a contemporary approach can maximise the sense of space. Light, neutral colours can create an airy and open feel, while smart storage solutions like built-in cabinets or floating vanities help keep the area uncluttered. Innovative lighting solutions, such as LED strip lights and skylights, can illuminate the space effectively, making it feel larger and more inviting.

A granny flat bathroom renovation in Sydney can perfectly marry modern design with functionality. By focusing on accessibility, smart use of space, and sustainable options, you can create a bathroom that’s both practical and aesthetically pleasing, ensuring comfort and style for all ages including;

– granny flat bathroom for elderly people to use

– a granny flat bathroom that needs the bath converted to a shower

– a granny flat used for rental purposes that has to get a new bathroom

3D virtual bathroom design with every renovation

One of the ways we make designing a new bathroom easy for a granny flat owner is to use 2D & 3D Virtual Design Software. This tool accurately uses the measurements from your property to design a bathroom that will suit your needs. We can place items in the room and move them around so that you get a virtual view of how everything will look in the new room.

This makes it much easier to work out your floor plan, bathroom renovation budget, an accurate list of building materials needed and enable us to provide a fixed price renovation quotation. It removes all the guesswork & is better than hand drawn sketches or a few bullet points written on a quote.

Bathroom design has changed a great deal during the last 20 years and a lot of Sydney homes have small bathrooms that are typically 3m x 3m in size. Although, for a lot of floor plans there might be a laundry or linen cupboard that can also be used to change the configuration of the walls to create more space to work with. 

Passion Built can even help move your bathroom plumbing so that a room can be re-configured to suit a new custom designed layout that perfectly suits your needs

Affordable bathroom renovation for a granny flat

We can answer any questions you have about getting a granny flat bathroom renovation


When renovating a granny flat bathroom in Sydney, several key considerations should be taken into account to ensure the space is both functional and aesthetically pleasing:

Compliance with Local Regulations:
First and foremost, check the local building codes and regulations in Sydney. This includes ensuring compliance with the Building Code of Australia (BCA) and any specific requirements set by the local council. It’s essential to obtain the necessary permits before starting the renovation.

Space Optimisation:
Granny flats are often limited in space. Clever design solutions like corner sinks, wall-mounted toilets, or sliding doors can help maximise the available space. Consider a layout that optimises functionality without feeling cramped.

Accessibility and Safety:
This is particularly crucial if the granny flat is intended for elderly occupants. Features like walk-in showers with no steps, grab rails, non-slip flooring, and higher toilet seats can enhance safety and accessibility. Lever taps and easy-to-reach storage can also be beneficial.

Lighting and Ventilation:
Good lighting is essential in a bathroom, especially in a smaller space. Consider natural light, supplemented by LED lighting for energy efficiency. Adequate ventilation is also crucial to prevent mould and dampness, common issues in Sydney due to its humid climate.

Water Efficiency:
Sydney, like much of Australia, values water conservation. Installing water-efficient fixtures such as low-flow toilets and shower heads can reduce water usage and save on utility bills.

Durability and Maintenance:
Choose materials that are not only aesthetically pleasing but also durable and easy to clean. High-humidity levels in Sydney can affect certain materials, so it’s important to select those that can withstand moisture.

Style and Aesthetics:
The design should complement the overall style of the granny flat. Modern, minimalistic designs with neutral colours can make the space feel larger and brighter. However, personal preference should also play a part in the selection of tiles, paint, and fixtures.

Budget Considerations:
Set a realistic budget for the renovation. It’s important to balance quality with affordability. Getting quotes from various contractors and pricing out materials beforehand can help in planning the budget more accurately.

Professional Help:
For electrical and plumbing work, it’s advisable to hire licensed professionals. Not only is this often a legal requirement, but it also ensures the safety and reliability of the renovation.

Sustainable Practices:
Consider environmentally friendly options such as recycled materials, solar-powered lights, or efficient heating systems. This is not only good for the environment but may also offer long-term cost savings.

By taking these considerations into account, the renovated granny flat bathroom can be a comfortable, safe, and appealing space that adds value to the property.

Passion Built is a bathroom renovation company located in Alexandria. We don’t have a showroom because we provide a mobile service where we come to you. We are able to do renovations in all suburbs of Sydney by sourcing materials from multiple locations & getting them delivered to your site.

According to Hi Pages the average cost to renovate a living room is between $10,000 and $15,000. Although this average changes quickly if the flooring is going to be changed, walls moved or expensive materials are chosen.

Bathrooms & kitchens will typically cost between $15,000 and $30,000 to do a complete renovation but these rooms will also add the most value to a property compared to adding a garage or doing landscaping.

The cost to renovate isn’t really that much different to other suburbs of Sydney unless you are living on an island or a steep block with difficult access.

The other big variable is whether you live in a heritage-listed property which may also require special approvals before changing any of its features.

Passion Built is a licensed builder in Alexandria that can be hired as a contractor for home renovations anywhere in New South Wales.

We have $10,000,000 in public liability insurance and provide HIA Home Warranty Insurance for all projects over $20,000 to give you peace of mind. This is backed with our 10-year warranty on the work we complete.

Hiring Passion Built as a contractor for your home renovation is easy with a simple to follow process that includes a fixed price quotation with no hidden surprises.

This makes it simple to hire us for any type of building work needed like a bathroom renovation.

Well for sure you can spend $1,000, $2000 or $20,000 on a renovation. There is no fixed minimum amount that is required although whether that is a sensible amount to spent will depend on your situation & what you want to achieve. We are a contractor that specialises in doing complete bathroom renovations where the whole room is stripped back to the timber or brick framework. This type of bathroom renovation is the most expensive, but also delivers the best quality finish. If you want a renovation that costs less than $10,000 then that is a makeover where you use the existing items and give them a freshen up with new paint, taps and fittings, but leave everything else. Typically most people are trying to renovate a house with an eye on increasing its value, therefore you have to be careful how much is spent. There will be a point where the value of any renovations won’t proportionally add value to your home. Generally speaking if the property is worth $500,000 then you should aim to spend around $50,000 and focus on the big areas like the kitchen and bathroom.
Passion Built can deliver complete bathroom renovations for houses, units, apartments or retail shops. We have extensive experience renovating bathrooms of all sizes to create new ensuites, kids bathrooms or even new floor plans that can include a freestanding bathtub. A complete bathroom renovation normally means stripping back the whole room to the bare building structure. A makeover or remodel usually means using the existing toilet / shower / bath & updating maybe the paint, lighting or taps to give the room a fresher look.
