Types of Bathrooms We Renovate 

At GSM Plumbing, we have the skill and expertise to manage all types of bathroom renovations in Castle Hill and across Sydney. Some typical residential bathrooms we renovate include:

Main Bathrooms

Your bathroom should represent your own style, way of life, and vision. We will collaborate with you to create a bathroom design that is not only aesthetically beautiful but also makes efficient use of space.


For the finest possible experience, your toilet should have a few elements that are an absolute must. This includes good quality tiling, excellent lighting and a great design. We'll transform your space to give it an elegant and functional finish.


An ensuite design, style and function should be able to hold up against your daily routine and personal taste. We can revamp an outdated ensuite and transform it into a modern oasis that meets your everyday needs easily.

Disabled Bathrooms

For the elderly or less mobile members of your household, your bathroom should be well organised, easy to navigate and functional. We can help you design and build a more accessible and safe bathroom that is practical and modern.
