Phillip Island & the Bass Coast. Director-led bathroom renovations across Bass Coast Shire and surrounds.
Bathroom Renovations on Phillip Island & the Bass Coast
RAW Building Group designs and builds premium bathroom renovations across Phillip Island and the Bass Coast, delivered as part of larger home renovations and extensions. Rod or Will runs your project in person, from the first site visit to handover.
Why Bass Coast homeowners choose RAW
Director-led builds. You deal with Rod or Will directly, not a project manager
Fixed budget and timeline agreed before construction starts
Bathrooms delivered as part of substantial renovations, extensions and whole-home transformations
A limited number of projects at a time, so quality never gets stretched thin
Renovating a Bass Coast Bathroom
Bass Coast homes come with their own set of considerations. Original beach shacks on raised stumps, 1970s and 80s holiday homes, newer coastal luxury builds and lifestyle properties all sit side by side. The bathrooms in older shacks and holiday homes are often the first thing to show their age. Salt air and coastal humidity accelerate failure where waterproofing was substandard or never installed properly to begin with.
Our Silverleaves project is a strong example of what's possible: a 1970s beach-house bathroom reimagined for year-round use, with underfloor heating, considered finishes and a designer collaboration shaping the result. We work across Cowes, Ventnor, Silverleaves and over to Venus Bay, with bathrooms specified for the coastal climate.
Common drivers for a bathroom renovation on the Bass Coast:
A 1970s beach-shack bathroom at the end of its life, with failing or non-existent waterproofing
A holiday-home bathroom being brought up to year-round standard for permanent living
An ensuite added as part of extending a holiday home for permanent occupation
Upgrading bathrooms to premium standard for holiday rental use
A spa-style ensuite designed around coastal light and views
Underfloor heating added for comfort and to help manage coastal humidity
What a RAW Bathroom Renovation Includes
A bathroom renovation with RAW is a considered building project, not a cosmetic refresh. We handle structural changes, custom joinery, waterproofing, tiling and premium fittings as one coordinated build.

Structural, waterproofing and coastal work we regularly handle in Bass Coast bathrooms:
Full bathroom reconfigurations in older beach shacks and 1970s or 80s holiday homes
New bathrooms and ensuites added through rear or side extensions
Relocating plumbing stacks, wet areas and drainage, often from original single-bathroom layouts
Full waterproofing to AS 3740 by licensed waterproofers, signed off as part of the build
Underfloor heating installed to help manage coastal humidity and dry the room between uses
Specifying marine-grade fittings and corrosion-resistant materials where salt exposure applies
Working within coastal planning and bushfire overlays where they apply
Structural Waterproofing & Coastal Work in Bass Coast Bathrooms
Older Bass Coast bathrooms almost always need their waterproofing stripped back to substrate and installed again from scratch to current Australian Standards (AS 3740). In many pre-1980 beach shacks and holiday homes there was no proper waterproofing to begin with, and the coastal climate shortens the life of anything substandard. The only way to do a bathroom here properly is to start from a bare shell.
Coastal planning overlays and in some cases bushfire overlays also shape what's possible. We handle all of it. Engineers, Bass Coast Shire Council permits, plumbers, licensed waterproofers, tilers, cabinet makers and glaziers coordinated as one project, with materials specified for a coastal climate.

Why RAW Building Group
RAW is director-led. Rod and Will run every project in person, so decisions happen quickly and nothing gets lost between a salesperson and a site manager.
We deliberately limit the number of projects we take on. That means your Bass Coast bathroom gets proper focus, even with the travel from Melbourne's south-east. The waterproofing gets checked, the tiling gets watched, and the finishes get inspected before handover.
No hard sell. No dramatic promises. Just quality building, delivered honestly.
Bathroom Renovation Cost on the Bass Coast
Cost depends on your project scope. A premium bathroom with structural changes, custom joinery and quality finishes typically sits between $45,000 and $90,000. Bathrooms done as part of a larger extension or whole-home renovation typically cost between $35,000 and $75,000 each, with cost efficiencies when multiple bathrooms are built in one project.
For coastal and lifestyle properties, cost may include additional scope for coastal-grade materials, bushfire-rated construction where overlays apply, and trades coordination. We provide a detailed cost breakdown during design, and a fixed price before construction starts. No hidden extras.
See Our Bathroom Work
Our Silverleaves bathroom transformation on Phillip Island shows what's possible when a 1970s beach-house bathroom is reimagined for year-round use. Underfloor heating, considered finishes and a designer collaboration delivered a bathroom built for the coastal climate and the way the family lives in it.
The multiple bathrooms and ensuites at our Tynong North farmhouse are another strong example of what's possible when every wet area is designed as part of the whole home. Each project is built to suit the home and the family, not pulled from a template.
Frequently Asked Questions
-
Yes. We regularly work in Cowes, Ventnor and Silverleaves across Phillip Island, with projects on the surrounding Bass Coast and across to Venus Bay. We service Smiths Beach, Rhyll, Newhaven, San Remo, Inverloch, Cape Paterson and Wonthaggi, and across the South Gippsland coast.
-
Yes. Our Silverleaves transformation is a good example: a 1970s beach-house bathroom brought up to year-round standard with underfloor heating and considered finishes. We handle structural changes, services upgrades, waterproofing to AS 3740, and extensions, with materials specified for coastal conditions.
-
A standalone complex bathroom typically takes 6 to 10 weeks. Bathrooms as part of a larger renovation or extension are integrated into the overall 8 to 16 month build program. Timelines are confirmed during design and account for the travel to and from the Bass Coast.
-
A premium bathroom with structural changes typically costs between $45,000 and $90,000. Bathrooms done as part of a larger project typically cost $35,000 to $75,000 each. For coastal properties, cost may include additional scope for coastal-grade materials and bushfire-rated construction where overlays apply. We provide a fixed price before construction starts, with no hidden extras.
-
Yes. All waterproofing is installed to AS 3740 (Waterproofing of Domestic Wet Areas) by licensed waterproofers, and signed off as part of the build. Older Bass Coast beach shacks and holiday homes often have little or no original waterproofing. The combination of salt air and humidity accelerates failure where it exists, so we strip back to substrate and install from scratch. Correct waterproofing is non-negotiable in a RAW bathroom.
-
Yes. Whole-home renovations and transformations are where our work is strongest. Our Silverleaves and Cowes projects are good examples of bathrooms designed and built as part of a full home renovation, with everything coordinated by one director.
