Unfortunately there are millions of answers as to just how much a custom bathroom in Sydney costs and there isn’t any particular situation that you can compare to because each property is different. Some people might just need a small 3 x 3 sized bathroom custom built & others might want a wall removed to combine a laundry & old bathroom into a larger one – that is the benefit of custom built bathrooms, you can decide what you want, there are no restrictions other than local council regulations, heritage requirements or your budget. 

So if you are thinking about starting a custom designed renovation project, the very first place to start is creating a very clear goal and defining the purpose of your renovation. This will make it easier to then come up with ideas to then work out your budget, products to be used and the planning required.

For many people renovating a custom bathroom in Sydney is the fastest way to add value to a property, besides the kitchen it is the most used part of the home & the one that can create wow factor. As a qualified and licensed builder we are able to renovate small bathrooms, an ensuite or master for retail shops, industrial buildings and residential houses or units.

Dylan and his team renovated my custom bathroom, laundry and kitchen in my unit in Alexandria. His team are excellent and I couldn’t be happier with the final product.

I was particularly happy with the quality of cabinet making, tiling in the bathroom, and painting.

Dylan is very responsive, trustworthy and a nice bloke to deal with. When problems arise (as they inevitably will) he tackles them quickly and without fuss. Highly recommended.

Completely custom designed bathrooms in Sydney

Passion Built can renovate your bathroom whether it is in a house, unit or retail shop. We have been doing more and more bathroom renovations in recent years as property owners have realised it is one of the best ways to add value to your home quickly. 

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

If you have a particular look you want to achieve or you’d like to follow a modern trend we are able to help you build a bathroom using the same materials, products and construction techniques. Floor tiles, timber vanities, mirrors, lighting, windows or even sky lights can all be used to create a unique, modern bathroom to suit your tastes & interior design goals.

Custom bathroom for old house in Sydney

Renovating houses is our most popular building contracted service because there are so many older homes in Sydney. In most situations we completely strip the existing room to start from a bare frame before installing new flooring, waterproofing and PC items. 

We don’t sell ‘kits’ or ‘makeovers’ – what we offer is the ability for you to craft a 100% custom designed bathroom with each item custom made or chosen to your tastes and budget.


Custom bathroom built in a unit or apartment in Sydney

Most units in Sydney are relatively new as housing density in New South Wales has changed slowly over the last few years with a lot of high rise blocks being built. Older units can be renovated just as easily as a house as all the fundamentals are similar.

The biggest difference is the proximity of dwellings and shared walls. We can handle all of those existing conditions to complete a renovation whether it is a rental unit or your apartment.

Custom designed bath or walk in shower installed in Sydney

A popular renovation choice is to add a bath tub into a room. There are so many modern products that are back to the wall designs or freestanding with deep sides. Depending on the property we can install a new bath and make sure that it can be used safely with the right flooring re-enforcement to handle the weight.


Affordable custom bathroom renovations in Sydney

Every home owner has lots of questions relating to renovating a bathroom, here are some of the most common ones


Passion Built is a custom 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 custom bathroom renovations in all suburbs of Sydney by sourcing materials from multiple locations & getting them delivered to your site.

Generally speaking renovating part of your house in Sydney or individual rooms will be cheaper than to rebuild. Although it depends on the extent of the building work required.

For older homes on large block of land it could be more economical to build a granny flat or studio in the backyard instead of renovating the existing rooms. While some single storey houses might benefit from adding another level to create an entirely new living area.

Each method has its pros and cons but if you are on a tight budget then you can use some clever renovating techniques to keep costs in control to give your home a new look.

Normally it can be 20-30% more to do a rebuild vs renovating. We can do a site assessment and provide a written, fixed price quotation and customise everything to your requirements.

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 in Sydney will vary depending on how difficult the site is to access, whether you live in a heritage-listed property which may also require special approvals before changing any of its features and of course the materials you decide to use.

Passion Built is a licensed builder in Sydney that can be hired as a contractor for any type of custom home renovation. 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 custom building work needed like a bathroom renovation.

Passion Built complete bathroom renovation company for combined bathroom and laundry in a unit in Lane Cove

Yes, we can renovate your property to custom build a combined a laundry and bathroom. This might require the removal of a wall or relocating your plumbing to accommodate the washing machine. Either way it is possible and some people do this to create more space or to improve the practicality of their home. So many modern appliances work very efficiently so heat or moisture isn’t a problem while many people don’t need a big sink in their laundry like the old days.

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.
Depending on the age of the bathroom it could be more economical and efficient to do a complete bathroom renovation. Older bathrooms may have issues with the flooring, walls or even water services that can create underlying long term issues. By removing all the old items and starting again it means everything is built to current Australian standards using modern building techniques and materials.

A custom bathroom refers to a bathroom that is designed and built to meet specific requirements and preferences of the homeowner or client, rather than being a standard design that is commonly found in many homes. Custom bathrooms can include unique features, layouts, and materials that are tailored to the individual’s needs and taste.

To build a custom bathroom, the first step is to consult with a professional designer or contractor who specialises in custom bathroom designs like Passion Built. We will work with a client to understand their needs and preferences, and develop a design plan that meets their needs.

The design plan for a custom bathroom can include a variety of features, such as:

Customised layout: The layout of the bathroom can be modified to meet the client’s needs, such as expanding the size of the shower, adding a separate tub, or changing the location of the sink and toilet.

Unique materials: Custom bathrooms often use high-end or unique materials that are not commonly found in standard bathrooms, such as marble or granite countertops, custom cabinetry, or high-end fixtures.

Specialised lighting: Custom bathrooms can incorporate specialised lighting to create a unique ambiance, such as LED lighting around the vanity mirror, or recessed lighting in the shower.

Customised storage: Custom bathrooms can include customised storage solutions, such as built-in shelves or cabinets, to maximize the use of space and meet the client’s storage needs.

Specialised fixtures: Custom bathrooms can include specialised fixtures, such as rainfall shower heads, jetted tubs, or smart toilets, that are not commonly found in standard bathrooms.

So it means you can choose any colour, texture, tap, tile, vanity, lighting, paint or other item to be installed in the bathroom – everything is 100% custom built for you.

Custom designed bathrooms take a bit more planning, a little bit more thought & slightly more preparation time compared ot other types of renovations. More effort goes into all the smallest design details because it is one of the most used spaces in a home. 

A newly built bathroom has to withstand conditions that include every day use, heat, moisture and big temperature variations. That is why it is important to choose a renovation contractor with experience, resources and the expertise to tackle these projects to perfection. 

For a custom build we will work very closely with each client to understand what their requirements and ideas for that space are. The design that is agreed to will then be highly functional, modern & include all the custom details that were required. We keep up with the  latest trends in bathroom design and know exactly how to incorporate those concepts into every project we get involved with.

The things that we include in our custom bathroom renovation can include;

  • Design planning and layout floor plans
  • Conducting concept discussions
  • Planning all the tiling for floors and walls
  • Plumbing design and installation
  • The paint to be used
  • The materials to be used
  • Planning the lighting fittings
  • Advice about the type of bathroom fixtures needed
  • Help with flooring materials options
  • Colour suggestions
  • Ventilation planning
  • Designing the cabinetry
  • Choosing technology like underfloor heating, music or other unique features like a steam shower.

With so many years of experience renovating in Sydney we have built a very strong network of tradespeople and suppliers. It’s how we ensure that all the materials are of the highest quality and that the workmanship is excellent too. For every job that we start we will;

  • Procure high quality materials
  • Provide our incredible workmanship
  • Deliver a professional approach
  • Timely completion of all work to an agreed schedule
  • Daily on-site supervision
  • Your living spaces left neat and clean at the end of each work day
  • We aim to complete the work within 2-3 weeks

There are several benefits to opting for a custom bathroom in Sydney over buying a pre-made package and these include;

  • Design Flexibility: With a custom bathroom, you have the freedom to design the space according to your specific needs, preferences, and style. You can do it yourself or work with a professional designer to create a unique layout, choose custom fixtures, materials, and finishes, and personalise the space to suit your taste.
  • Maximised Space Utilisation: Custom bathrooms allow you to make the most of the available space. Either we can help you or an interior designer can help you optimise the layout and create custom storage solutions to maximise functionality and efficiency. This is particularly valuable if you have limited space or an irregularly shaped bathroom.
  • Quality and Durability: Custom bathrooms often involve higher quality materials and fixtures compared to pre-made packages. You can select premium materials that offer durability and longevity, ensuring your bathroom stands the test of time. This can result in fewer repairs or replacements in the future.
  • Personalised Experience: By customising your bathroom, you can create a space that reflects your unique personality and lifestyle. Whether you prefer a luxurious spa-like atmosphere or a sleek, minimalist design, a custom bathroom allows you to tailor the space to your individual preferences, enhancing your overall experience and satisfaction.
  • Enhanced Functionality: A custom bathroom can be designed to meet your specific functional needs. You can incorporate features like walk-in showers, dual sinks, custom lighting, or smart home technology to enhance convenience and usability. Customisation ensures that every element of the bathroom serves a purpose and contributes to your daily routine.
  • Increased Home Value: A well-designed and professionally executed custom bathroom can significantly increase the value of your home. Buyers often appreciate unique, customised features, and a thoughtfully designed bathroom can make your property stand out in the market.

It’s worth noting that opting for a custom bathroom typically involves a higher upfront cost and a longer construction timeline compared to buying a pre-made package. However, the ability to create a tailored space that perfectly meets your needs and preferences often outweighs these considerations for many homeowners. Best of all what you create is therefore unique and won’t be recognised by people who see it.
