Bathroom renovations Northern rivers NSW

Bathrooms built to last. Designed to impress

OJM Builders delivers designer bathroom renovations across the Northern Rivers — from the first tile to the final fixture.

We coordinate every trade, every inspection, and every detail so you don't have to. One point of contact from start to finish, no handoffs, no surprises.

Whether you're after a clean modern remodel or a full custom build, we bring the same precision and care to every bathroom we touch.

What We Do

A bathroom renovation involves more moving parts than most people realise — plumbers, tilers, electricians, waterproofers, plasterers, cabinetmakers. Getting them all on site in the right order, at the right time, is where most renovations fall apart.

At OJM Builders we manage the entire process. You deal with one person from the first conversation to the day we hand over the keys. No chasing trades, no coordinating schedules, no surprises on the bill.

We handle:

  • Full bathroom demolition and strip out

  • Waterproofing and wet area compliance

  • Custom tiling and stone finishes

  • Vanities, tapware, and fixture installation

  • Shower screens and bath installations

  • Custom cabinetry and joinery

  • Lighting and electrical fit off

  • Plumbing rough in and fit off

  • Ensuite and powder room renovations

  • Accessible and mobility bathroom builds

Why OJM Builders

When you build with OJM you deal with the director from the first conversation to final handover and everything in between. No handoffs. No turning up at the start and disappearing until the end.

We keep it small by design because we believe the best results come from staying involved at every stage. Every bathroom we build gets the same attention to detail whether it's a compact ensuite or a full master bathroom renovation.

We work with designers and architects across the Northern Rivers and are experienced in executing complex plans to an exacting standard. If you've got a vision, we know how to build it.

Frequently Asked Questions

How much does a bathroom renovation cost in the Northern Rivers?

Bathroom renovation costs vary depending on size, finishes, and scope. A standard bathroom renovation in the Northern Rivers typically starts from $18,000 to $25,000 for a full remodel. High end custom builds with designer fixtures and stone finishes can range from $35,000 to $60,000 and above. Every job is different, contact us for an accurate quote based on your specific brief.

How long does a bathroom renovation take?

A standard bathroom renovation takes between three to six weeks from demolition to handover depending on scope and trade availability. We plan every job carefully before we start so there are no unnecessary delays once work begins.

Do I need council approval for a bathroom renovation in NSW?

Most bathroom renovations in NSW are considered exempt development and don't require a DA. However if you're moving walls, changing the footprint, or the property is heritage listed you may need approval. We'll advise you on this during the quoting process.

Do you supply the tiles and fixtures or do I?

Either works. We can work from your selections or connect you with our preferred suppliers across the Northern Rivers. We'll guide you on what works within your budget and what will hold up long term.

Do you handle all the trades or do I need to organise my own?

We handle everything. Plumber, tiler, electrician, waterproofer, plasterer — all coordinated by OJM so you have one point of contact throughout the entire renovation.

Do you work with interior designers and architects?

Yes — we regularly work alongside designers and architects across the Northern Rivers and are experienced in building to detailed plans and specifications. If your designer has a vision, we know how to execute it.

This is a ballpark only, built from our real trade rates — not a fixed quote. Includes a 20% Builder Management & Compliance fee, covering trade coordination and scheduling, verifying work against the NCC and relevant Australian Standards, quality control at each stage, and single-point accountability for the job. Real pricing depends on what's actually behind your walls, plumbing layout, and trade access, which is exactly what our paid scoping process is for: site inspection (including inspection holes where needed), each trade pricing their own work on site, and a fixed number you can rely on before you commit.
