Questions to Ask Your Bathroom Renovator

Choosing who builds your bathroom

A bathroom renovation brings several trades into your home for weeks, involves work that will be hidden beneath tiles for decades and represents a significant investment. Choosing the right renovator is as important as choosing the right tiles. The best way to compare renovators is to ask clear questions and listen carefully to the answers.

This guide gathers the questions we believe every homeowner in Drouin and West Gippsland should ask before engaging a bathroom renovator, along with what good answers sound like.

Licensing, insurance and compliance

Are you licensed and insured?

Bathroom renovations involve building work, plumbing, electrical work and waterproofing. Ask which licences and registrations the business and its trades hold and what insurance covers the work and the people working in your home. A reputable renovator will answer readily. In Victoria, domestic building work above certain thresholds requires a registered builder and specific insurance, and plumbing and electrical work must be carried out by licensed practitioners.

Who carries out the plumbing and electrical work?

Plumbing must be done by a licensed plumber and electrical work by a licensed electrician. Ask whether these trades are part of the team or subcontracted, and whether you will receive compliance certificates.

Is a permit needed?

Most like-for-like bathroom renovations do not need a building permit, but structural changes, such as removing load-bearing walls or extending the house, may. Plumbing work requires compliance certification. A good renovator will explain what applies to your project.

Waterproofing

How will the bathroom be waterproofed?

Waterproofing is the most important part of a bathroom, and the least visible. A good answer explains:

• The membrane system and why it suits your substrate
• That waterproofing is done to AS 3740
• Where waterproofing will be applied and to what heights
• How junctions, wastes and penetrations will be treated
• How long the membrane will cure before tiling

Will I receive photographs of the membrane?

Photographs show the membrane before it is covered and are valuable for your records.

Who does the waterproofing?

In Victoria, waterproofing should be carried out by an appropriately qualified person. Ask who will apply the membrane and how their work is checked.

Scope and quotation

What is included in the scope?

A clear written scope lists every stage: demolition, disposal, structural repairs, plumbing, electrical work, linings, waterproofing, tiling, fixtures, fit-off, cleaning and any allowances. Ask about anything that seems vague.

What is excluded?

Exclusions are as important as inclusions. Common exclusions include painting outside the bathroom, asbestos removal, structural repairs beyond a stated allowance and supply of certain fixtures.

How are hidden problems handled?

Older bathrooms often hide damage behind tiles: rotten framing, damaged floors, corroded pipes or failed waterproofing. Ask how such issues are identified, communicated and approved before additional work is done.

Who supplies fixtures and finishes?

Some renovators supply everything, while others allow you to supply your own tiles and fixtures. Ask how selections are made, who orders products and who is responsible if items arrive damaged or late.

Design and selections

Can you help with design?

Ask whether the renovator offers design guidance, layout options and help with selections. A design consultation should cover layout, storage, lighting, ventilation, heating, accessibility and finishes.

Can the layout change?

Moving the toilet, shower or vanity affects plumbing and drainage. Ask what is feasible in your home.

How will ventilation be improved?

In Drouin’s cool, damp climate, a properly sized exhaust fan ducted outside is essential. Ask how the renovator approaches ventilation.

Process and timeline

How long will the renovation take?

Ask for an estimated timeline, including demolition, rough-in, waterproofing cure time, tiling and fit-off, and how weather or product lead times might affect it.

How long will we be without a bathroom?

If this is your only bathroom, ask how many days the toilet and shower will be unavailable and what options exist.

Who will be on site and when?

Ask who manages the project, who you contact with questions and how often you will receive updates.

How will our home be protected?

Ask how floors, paths and furniture will be protected, where materials will be stored and how waste will be removed.

Older homes

Will you check for asbestos?

Homes built before 1990 may contain asbestos in bathroom linings and floors. A good renovator checks before demolition and arranges testing and licensed removal where needed.

How do you handle homes on stumps?

Timber floors move more than slabs. Ask how the renovator will assess the floor, stiffen it if needed and choose substrates and membranes that suit timber movement.

What about tank water and septic systems?

On rural properties around Drouin, ask how the renovator will choose fixtures for your water pressure and whether adding fixtures affects your septic system.

Communication

How do you communicate during the project?

Regular updates, clear answers and prompt responses make a renovation calmer. Ask how decisions are recorded and how changes are approved.

How are variations handled?

Changes to the scope during construction are common. Ask how variations are documented and approved in writing before work proceeds.

Handover and aftercare

What happens at handover?

A walkthrough should cover how everything works, care instructions and documentation.

What documentation will we receive?

Expect compliance certificates for plumbing and electrical work, waterproofing documentation, product warranties and care instructions.

What happens if something goes wrong?

Ask how defects are reported and resolved, and what warranties apply to workmanship and products.

Past work

Can we see examples of your work?

Photographs of completed bathrooms, especially in homes similar to yours, show the renovator’s standard of finish. Ask about projects in Drouin, Warragul or nearby towns.

How do you handle difficult projects?

Ask about a project that presented challenges and how it was resolved. The answer reveals problem-solving and honesty.

Questions about materials

Which tiles, adhesives and grouts do you recommend, and why?

Ask why a particular adhesive or grout suits your floor and wall substrates, and whether the products are compatible with the membrane system. Products from one system are often designed to work together.

What substrate will be used on the floor?

On timber floors, the substrate under the tiles affects stiffness and long-term performance. On slabs, ask how falls are created and whether a screed is needed.

How are movement joints handled?

Tiled surfaces need movement joints at corners, changes of plane and perimeters, filled with flexible sealant. Ask where they will go and how they will look.

Questions about your household

A good renovator asks questions too. Expect to be asked:

• Who uses the bathroom and when?
• Do you need a bath?
• Are there accessibility needs now or in the future?
• What frustrates you about the current room?
• How do you feel about cleaning grout, glass and tapware?
• What is your preferred timing?

If a renovator does not ask about your household, they may be designing for a generic bathroom rather than yours.

Questions about site practices

• What hours will trades work?
• Where will the skip or trailer go?
• How is dust controlled?
• Will the site be cleaned each day?

Red flags

Be cautious if a renovator:

• Cannot explain their licensing or insurance clearly
• Offers a quote without visiting the home
• Is vague about waterproofing or dismisses its importance
• Pressures you to sign quickly
• Asks for large payments well ahead of work being done
• Has no written scope or contract
• Will not provide compliance certificates

What a good consultation looks like

A thorough design consultation involves measuring the room, inspecting structure, plumbing and ventilation, checking for signs of water damage and discussing how you want the room to work. Afterwards you should receive a written scope and quotation that clearly sets out the work. You should never feel rushed to decide.

Our approach

We are a licensed and insured bathroom renovation team based in Drouin, working across Warragul, Longwarry, Bunyip, Garfield, Jindivick, Labertouche, Buln Buln, Neerim South and surrounding towns. We welcome every question in this guide. At each design consultation, we inspect the room thoroughly, explain waterproofing to AS 3740, discuss hidden damage and asbestos where relevant and provide a clear written scope and quotation. We photograph membranes before tiling, coordinate licensed plumbers and electricians and provide full documentation at handover.

Comparing several renovators

If you speak with more than one renovator, compare scopes line by line rather than looking only at the bottom line. One quotation may include structural allowances, asbestos testing, heating, ventilation upgrades or premium waterproofing systems while another leaves them out. Ask each renovator to clarify differences. The renovator who explains the work most clearly and answers questions most openly is often the one who will manage the project best.

Questions about handover and aftercare

• What documents will I receive at the end of the job?
• Will I get waterproofing photos and compliance certificates?
• What warranties apply to workmanship and to the products installed?
• Who do I contact if something needs attention after handover?
• How should I care for the grout, silicone, glass and tapware?

A renovator who answers these clearly before work begins is more likely to support you well after the job is finished.

Questions about communication

• Who will be my main contact during the job?
• How often will you update me, and in what form?
• How are changes to the scope agreed and recorded?
• What happens if a delay occurs?

Clear answers show that the renovator has a process, not just good intentions.

Write your questions down before each meeting and keep notes of the answers. Comparing renovators side by side is much easier when you have asked each of them the same questions in the same order.

Trusting your instincts

Beyond technical answers, notice how each renovator listens. Do they ask about your household and how you use the room? Do they explain options clearly without jargon? Do they turn up on time and respond promptly? These small signs indicate how the project will run.
