What Makes Us Different

We Are Licensed Builders

The bathroom is one of the most challenging rooms to renovate. As registered builders, you’ll have the peace of mind knowing that your bathroom renovation is backed by a 7-year structural workmanship guarantee.

We Take Away the Risk

Using a general tradesperson for a bathroom or laundry renovation is risky and costly, especially if things go wrong. As bathroom renovation specialists, we provide expert guidance over the entire renovation process—from design and layout to choosing the best fixtures, fittings, and plumbing solutions.

We Save You Time & Money

Renovating doesn’t have to be stressful or expensive. We help you avoid the hassle of shopping around or overpaying for materials. With access to exclusive trade supplier pricing, we help you source quality tiles, tapware, and fittings at discounted rates.

We Offer Full Project Insurance Plans

Your project will be protected by one of the best industry warranty protection plans available. Unlike many renovators, we provide extra security and peace of mind—ask us about our insurance options.

We Have a High Quality Trade Team

We don’t use random or inexperienced tradespeople. Over the past 9 years, we’ve built a trusted team of professionals, meaning you can be confident in the quality and consistency of the work delivered.

Trusted In the Brisbane Building Insurance Industry

We’ve been selected as accredited builders to partner with leading insurance builders in Brisbane. Our team is regularly called on to rectify home insurance claims related to bathroom and laundry damage, ensuring everything is repaired to the highest standard. With an excellent track record, you can trust us to get the job done right the first time.
