About Us
Your Local Experts in Bathroom & Laundry Renovations
Brisbane Bathroom Specialists is a division of Relianzi Construction Pty Ltd, a QBCC-licensed and fully insured company (Licence No: 1311 425). With over 9 years of experience and 265+ successful projects, we specialise in delivering high-quality bathroom and laundry renovations that are built to last.
Renovating a bathroom is one of the most complex home improvement projects, requiring expert coordination of multiple trades, compliance with Queensland building regulations, and a deep understanding of waterproofing, tiling, plumbing, and structural integrity. That’s why homeowners, property investors, and insurance companies trust us to get the job done right the first time.
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.
