How to Choose a Bathroom Renovation Company

Start by comparing like with like

A bathroom quotation is not only a price. It is a description of who will do the work, what will be supplied, how the project will be managed and which risks remain with you. A lower total may simply contain fewer tasks, allowances or protections.

Shortlist suitable companies first, then compare written scopes line by line. This checklist can reduce uncertainty, but it cannot guarantee a project outcome.

1. Verify the business and the people doing the work

Ask for the legal business name and ABN, then confirm that the company and the person responsible for the work hold the registrations or licences required for your project. Requirements vary with the work and contract value, so check current Victorian guidance rather than relying on a logo or verbal assurance.

Ask for current public liability insurance details and whether other cover, permits or domestic building insurance apply to your particular contract. Confirm the answer with the relevant authority or insurer when it matters.

• Who is the contracting party, and who is accountable for the whole project?
• Which licensed or registered trades are required for plumbing, electrical, waterproofing and building work?
• Can the company provide current insurance evidence and explain what it does and does not cover?
• Who will supervise the site, and who should you contact when a question arises?
• Can you review recent, comparable projects rather than only general testimonials?

Clarify responsibilities and subcontractors

Bathroom work depends on coordinated demolition, carpentry, plumbing, electrical work, waterproofing, tiling, caulking, glazing and fit-off. These people may be employees, regular subcontractors or specialist suppliers. The employment arrangement alone does not prove quality.

What matters is whether the renovator selects suitably qualified people, defines each responsibility, controls the sequence of work, checks hand-offs and remains accountable for the completed scope. Ask whether you will need to engage or pay any trade directly.

• Which trades are employees, regular subcontractors or engaged separately by the homeowner?
• How are licences, insurance, experience and workmanship checked?
• Who schedules the trades and resolves defects or incomplete hand-offs?
• Who protects the home, manages access, removes waste and completes the final clean?
• Who supplies certificates, warranties, manuals and care instructions at handover?

2. Test the quality of the quotation and scope

A useful proposal should let both parties understand the same finished result. Look for room-specific detail, product descriptions and a clear division between fixed items, selections, provisional allowances and excluded work.

Ask how hidden damage will be handled. No renovator can see every condition behind tiles and walls before demolition, but the proposal should identify known risks, explain its assumptions and set out a process for discoveries.

• Demolition, disposal, protection and any hazardous-material process.
• Structural repairs, wall and floor preparation, plumbing and electrical changes.
• Waterproofing extent, floor falls, drainage details, tiling areas, grout and sealant.
• Fixtures, fittings, cabinetry, shower screen, accessories and who supplies each item.
• Product brands or specifications, quantities, finish assumptions and allowance amounts.
• Permits, inspections, certificates, cleaning and handover documents.
• Explicit exclusions, owner responsibilities and work priced separately.

Understand variations, allowances and payments

A variation changes the agreed scope, price or timing. Before signing, ask how variations are described, priced and approved. Except for genuine urgent safety work, avoid a process where extra work proceeds before you receive the reason, cost and schedule effect in writing.

Check whether an attractive quotation relies on low allowances that may not match your selections. The payment schedule should identify what milestone has been reached, not merely a date on the calendar.

• What is fixed, what is an estimate and what is a provisional allowance?
• What evidence will be provided when an unforeseen condition is uncovered?
• Who may authorise a variation, and must approval be written?
• Do margin, delivery, disposal or administration charges apply to variations?
• How can a variation change the completion date and payment schedule?

3. Check how the project will be delivered

Ask for a realistic sequence rather than a promise that nothing will change. Product lead times, inspections and hidden conditions can affect a renovation; a good process explains how delays and decisions will be communicated.

• What needs to be selected or ordered before the start date?
• Who provides the project schedule and progress updates?
• How will dust, noise, water shut-offs, access, pets and security be managed?
• What inspections or quality checks happen before work is covered?
• How are defects recorded, rectified and signed off before final payment?

Read guarantees and warranties, not just the headline

Ask for workmanship guarantees and product warranties in writing. Check their duration, coverage, exclusions, maintenance requirements, claim process and whether labour or consequential work is included. A long headline period is less useful if the terms are unclear.

Also distinguish a company guarantee from rights that may apply under Australian Consumer Law or building legislation. This guide is general information, not legal advice; obtain independent advice before signing if the contract or risk is unclear.

Concise contractor comparison checklist

Use the same questions for every shortlisted renovator. Record the answer and where it appears in the proposal or contract rather than relying on memory.

• Business identity, required credentials and current insurance verified.
• One person or company clearly accountable for the complete project.
• Employees, subcontractors and owner-engaged trades identified.
• Detailed inclusions, specifications, allowances and exclusions supplied.
• Owner selections and responsibilities listed with due dates.
• Written variation and unforeseen-work process explained.
• Milestone-based payment and realistic scheduling process provided.
• Site protection, communication, inspections and handover defined.
• Guarantee and warranty terms supplied in writing.
• Comparable completed work and references checked.
