I’m King and Sons Electrical in Melbourne VIC, and I provide expert Bathroom Exhaust Fan Installation across the city. A wet room without proper ventilation traps humidity and odours, which leads to mould and long‑term damage.
I handle end‑to‑end work: selecting the right unit, safe wiring, venting to the outdoors and neat finishes. I assess ceiling access and external exit points so the unit runs quietly and lasts.
You’ll get clear advice on options that suit your budget and home. I prioritise compliance, correct earthing and energy efficiency, and I test performance before I finish the job.

Why proper ventilation matters in your bathroom right now
Moist, stale air shortens the life of paint and plaster and raises the risk of mould in any home.
Moisture from a long shower or hot bath sits on cold surfaces. That leads to fogged mirrors, damp skirtings and mildew that is costly to remove.
Good ventilation quickly moves humid air outside and stops odours from lingering. Quiet, efficient exhaust fans make it easy to use the system every time and keep indoor air fresher over time.
- Melbourne’s variable humidity means condensation can persist through cooler months; proper ventilation limits wet patches.
- Extracting moist air after a shower reduces mould and protects paint, plaster and cabinetry.
- Timed or humidity‑sensing controls automate run‑on and improve indoor air quality in busy households.

Choosing the right exhaust fan for your space
I start by matching unit type and capacity to the room, so you get reliable extraction with low noise and the right power for daily use.
Types and where they suit:
- Ceiling units vent upward through short ducts and must terminate outside, not into attic space.
- Wall models pass straight through an exterior wall — handy where roof access is limited.
- Window options fit into a pane and expel air without duct runs, common in apartments.
- Inline units sit in the ceiling cavity and are quieter; they can serve multiple rooms via ductwork.
Sizing and performance: I calculate room volume (L × W × H in metres), choose an appropriate ACH (15–25 ACH for showers; 6–8 ACH without), convert to CMH and then to CFM where needed. I pick a capacity slightly above the requirement to allow a safety margin.
| Feature | What I check | Why it matters |
|---|---|---|
| CFM rating | Matches CMH/ACH to room size | Ensures adequate airflow |
| Noise (sones) | 0.5–6 typical range | Lower sones = more comfort |
| Modern features | 3‑in‑1 heat, light & extraction | Saves space and wiring |
I balance power, efficiency and noise, and only recommend models with robust dampers and quality motors suited to Australian conditions. King and Sons Electrical can help with selection and supply — call 03 9122 8572.
Bathroom Exhaust Fan Installation: a practical step‑by‑step overview
I guide each job with a clear, step‑by‑step method so installs run safely and finish tidy.
I plan the location first, usually between the shower and toilet. I drill a small reference hole to check for pipes, joists or attic obstructions before cutting the main opening.
Cutting, mounting and duct routing
I measure and cut the intake opening, supporting the panel as I finish to avoid plaster cracks. The housing is fixed to framing and brackets extend to joists for a secure hold.
I attach a 90‑degree elbow to the outlet and seal with foil tape. I route the flexible duct to the nearest compliant exit — sidewall, roof or soffit — and always terminate outdoors, never into an attic or ceiling cavity.
Wiring, grille fitting and testing
I wire active to active, neutral to neutral and earth the housing before refitting the blower and grille. After restoring power I test airflow, noise and back‑draft closure.
| Step | Typical action | Time |
|---|---|---|
| Location check | Drill reference hole, confirm clearances | 15–30 minutes |
| Cut and mount | Cut opening, secure housing to joists | 1–2 hours |
| Duct & termination | Fit elbow, route duct, seal exterior cap | 1–3 hours |
| Electrical & test | Wire, earth, fit grille, verify operation | 30–60 minutes |
Tools: drill/driver, hole saw (4–4½”), jigsaw, spade bit, ladders and safety goggles. Typical DIY time is 6–8 hours depending on access and duct length.

Placement and venting best practice for clean, dry air
I plan the fresh‑air path and discharge together so steam leaves the room quickly and does not recirculate. Correct siting captures moisture at source and keeps surfaces dry.
Position near the shower or between bath and shower
I prioritise a location that captures steam at the source—directly over or beside the shower or between the bath and shower. I also set the unit opposite the fresh‑air entry so air sweeps through the room.
Keep ducts short and straight to reduce losses
Short, mostly straight duct runs preserve rated airflow and lower noise. I use gentle bends only when necessary and select the largest practical duct size to reduce static pressure.
Choose the best exit: sidewall, roof or soffit venting
Depending on your home, I will route the duct to a side wall, up through the roof or out via a soffit cap. All terminations are to the outside and fitted with a sealed cap and back‑draft damper.
Never vent into an attic, crawlspace or ceiling cavity
Discharging into an attic or similar enclosed space damages insulation and timber and creates mould risk. I will recommend an inline solution with a remote grille where ceiling exhaust placement is constrained.
| Exit type | Typical run | Pros | Cons |
|---|---|---|---|
| Side wall | Short, direct | Simple, low cost | Requires external wall access |
| Roof | Vertical up | Good gravity drainage | May need flashing work |
| Soffit | Short horizontal | Discrete cap, neat finish | Must avoid bird ingress |
| Inline (remote) | Flexible routing | Quieter grille, flexible location | More parts, higher cost |

Safety, compliance and when to call a licensed electrician
A licensed electrician must handle wet‑area power work to meet Australian standards. I isolate circuits, prove they are dead and earth all metallic housings before I connect any unit.
Electrical safety, isolation and Australian compliance considerations
I follow wet‑area wiring rules and test RCDs, continuity and earthing. I document results and provide compliance paperwork on completion so you have a clear record.
- Isolation: isolate and lock off circuits before work begins.
- Testing: verify dead, test RCDs and earth all metal parts.
- Sizing & options: I advise capacity and suggest inline or wall options when appropriate.
Melbourne installs: I service Greater Melbourne and surrounds
My team schedules jobs at convenient times and protects your finishes while working on site. I coordinate roof access and explain timers or controls so the unit runs efficiently and saves you time and cost long term.
| Item | What I check | Why it matters |
|---|---|---|
| RCD & continuity | Test trip and wiring continuity | Prevents electrocution and faults |
| Capacity | Match power to room size | Ensures effective extraction and low noise |
| Termination | Vent to outside, sealed cap | Protects insulation and timber |

Avoid these common mistakes and get pro‑level results
Small mistakes in sizing or routing can turn a simple upgrade into a costly, ongoing problem. I focus on correct size and sensible routing so the unit clears moist air and works quietly.
Undersized units and poor placement
Don’t guess the required capacity—match the fan to the room volume and expected use. If the size bathroom is wrong, extraction will be slow and mould risk rises.
Leaky, long or kinked duct runs
Long, crushed or kinked duct runs slash performance. I replace damaged duct, keep runs short and seal all joints to restore airflow and efficiency.
Ignoring noise ratings and maintenance access
Ignoring sones leads to annoying noise. I pick quiet models, mount them to reduce vibration, and position grilles for easy access and cleaning.
- Measure twice, cut once: a tidy hole protects plasterboard and avoids air leaks.
- Never vent to an attic: terminate outdoors with a sealed cap to protect timber and insulation.
- Consider inline exhaust: when ceiling or wall placement is constrained, a remote unit improves performance.
| Mistake | Consequence | How I fix it |
|---|---|---|
| Undersized unit | Poor airflow, lingering odour | Choose a fan slightly above required capacity |
| Long/kinked duct | Loss of airflow and efficiency | Replace with smooth, short duct and sealed joints |
| Poor access / noisy unit | Hard to clean, complaints about noise | Specify low‑sone models and ensure service access |
