At Expanse Builders, we believe the bathroom is the most important room in the house. Yet every day, we put up with little irritants in our bathrooms, because they aren’t designed for our lifestyles. Maybe the power points are in the wrong place, or there’s not enough storage and there are towels draped everywhere.

It doesn’t need to be that way. Expanse Builders specialise in creating beautiful custom bathrooms tailored for your lifestyle in Bayside, Melbourne. Whether you’ve bought a home with a plan to renovate a dated family bathroom, are updating your ensuite or it’s just time to refresh your existing setup, we’re here to create your bathroom your way.


Embarking on a custom bathroom project can be a daunting prospect. As your local Bayside bathroom experts, Expanse Builders are here to help you every step of the way.

Our in-depth consultation process provides the space to develop your ideas into firm concepts, and ensures you can visualise the end product through 3D modelling before any plans are drafted.

We only begin the installation process once we have a final design. We use the latest techniques and materials to ensure that your custom bathroom is built to the highest standard, managing all trades. All you need to do is walk in and start enjoying your bathroom once it’s completed.


3D modelling at the design stage is a core part of our process – providing you and us with reassurance and certainty that we’re creating your perfect custom bathroom

First, our design team comes to your Bayside, Melbourne property to measure your bathroom down to the millimetre – so that you can be sure the design will fit perfectly.  We then run through a detailed 3D presentation of the options with you, either in person or over a video call, which enables us to refine the design in real time. We can do this as many times as we need to, until you’re delighted with the end result.

We then draw up the plans and specifications for the renovation, including all of your specified inclusions. Our end-to-end service includes drawings, 3D renders, tile layouts, and a detailed project specification report with fixtures and fittings. You’ll know exactly what the finished product will look like before we sign any paperwork.
