Overview
Small Space, No Shortcuts on Waterproofing
Ensuites are compact, but that doesn't mean lower standards — waterproofing failures in a small, high-use space cause exactly the same damage as in a full bathroom. We treat every wet area to the same Australian Standard regardless of size.
Because ensuites are often tight on space, layout and fixture selection matter more than in a larger bathroom — getting the shower, vanity and door swing right the first time avoids an awkward, cramped result.
A genuine ensuite renovation starts from around $10,000+ cost of works at our budget rate, scaling up for premium fixtures, a frameless screen or heated flooring.
Ventilation is non-negotiable in a small wet area — an undersized or poorly ducted exhaust fan is one of the most common causes of mould and finish failure in ensuites, so we size and duct extraction properly rather than fitting the cheapest fan that fits the ceiling hole.
