Fan identity
Photograph the front, grille, label, model and any accessible side or rear connection without removing equipment or entering unsafe ceiling space.
Toilet Exhaust Fan Replacement Singapore: Match the Opening, Duct and Point
Quick answer
Send a full bathroom view, front and side photos of the existing fan, its label or model, opening measurements, duct or grille photos, switch behaviour, ceiling or wall access and postal code. FixMove can then distinguish a compatible replacement from new duct, opening, builder's or electrical work and issue an itemised S$ quote. Model, slot, duration and warranty are confirmed only in writing.
A fan that fits the visible grille may still be incompatible with the opening, depth, mounting support, duct, voltage, switch arrangement or permitted discharge route. Replacement should start with site evidence, not a universal fan-size or “wiring included” promise.
Choose replacement, diagnosis or a new installation scope
| Existing condition | Suitable first scope | Can be included when quoted | Not automatically included |
|---|---|---|---|
| Existing wall or window fan with confirmed compatible model and opening | Like-for-like replacement assessment | Named fan, removal, mounting, compatible existing connection and operating check | Glass, wall or opening alteration, new wiring, new duct or finish repair |
| Existing ceiling fan connected to an accessible duct | Fan and duct-interface assessment | Named fan, accessible connector or short interface and agreed operating observation | Concealed duct replacement, ceiling opening, cleaning, access platform or discharge-route approval |
| Fan hums, stops intermittently or has weak airflow | Fault and air-path diagnosis before replacement | Agreed accessible fan, switch and grille observations | Assuming the motor alone is faulty or a new fan will solve a blocked or unsuitable duct |
| New fan differs in size, depth or mounting | Alteration survey and itemised method | Adapter or support, opening change and making good only when expressly named | Treating builder's work or finish risk as standard replacement labour |
| No existing fan, opening, duct or electrical point | New ventilation installation proposal | Site-specific fan, air path, opening, duct, electrical and approval scopes | Using this replacement page as proof that any facade, riser or ceiling-void discharge is permitted |
What to send before pricing
Opening and mounting
Measure visible width and height or diameter, show wall, window or ceiling material, fixing points, support and nearby obstructions.
Duct and discharge evidence
Show the accessible duct, connector, grille or louvre and state where it appears to terminate; do not assume a concealed route or common-property outlet.
Electrical behaviour
State whether the fan is dead, noisy, intermittent or tripping, how the switch is arranged and whether any burning smell, heat or damage is present.
Access and property rules
Share ceiling height, hatch or panel access, ladder restrictions, HDB, condo or commercial property type, landlord or MCST rules and postal code.
Moisture and odour context
Describe condensation, mould, odour, leaks, drying habits, room openings and when the symptom occurs so a fan replacement is not sold as a guaranteed cure.
Replacement inclusions and exclusions
- Product: name the fan model, dimensions, rating, controls, grille, damper and whether it is supplied by FixMove or the customer; compatibility remains subject to the site.
- Removal and mounting: state the old-fan removal, support and fixings, adapter or frame, access method, protection, cart-away and making-good boundary.
- Duct and air path: define the accessible connector, duct or grille work and operating observation. Concealed duct, cleaning, new discharge route and approvals are separate.
- Electrical boundary: distinguish a suitable existing point from switch, circuit, isolator, fixed-wiring or fault work and name the appropriately licensed route where required.
- Performance boundary: the quote may record an agreed operating or airflow observation but cannot guarantee elimination of mould, odour, condensation, leaks or every building-ventilation problem.
- Commercial terms: require an itemised S$ total, planned attendance basis, variation approval, disposal, completion conditions and written workmanship, supplied-part or manufacturer warranty terms if any.
Exhaust fan replacement process
Send the fan quote packet
Provide model or label, opening dimensions, full-room and fan photos, accessible duct or grille evidence, switch behaviour, access and postal code.
Confirm replacement eligibility
Check whether a compatible fan can use the existing opening, mounting, duct interface and electrical point or whether diagnosis or alteration is needed first.
Separate every workstream
Itemise fan supply, removal, mounting, access, duct, builder's work, electrical work, testing, disposal and building approval dependencies.
Approve the S$ scope and slot
Confirm the model, inclusions, exclusions, licensed electrical route where required, planned timing, variation rule and written warranty terms if any.
Review the agreed completion checks
Confirm mounting, operation and the quoted accessible air-path check, then treat concealed restrictions or unrelated moisture causes as separate findings.
Electrical and building boundaries
A compatible fan replacement at an existing point is not the same as adding or altering fixed wiring, a switch, circuit or isolator. EMA advises consumers to engage and verify a Licensed Electrical Worker for electrical work. The accepted quote should identify the regulated electrical scope and responsible route where required. See EMA guidance on engaging Licensed Electrical Workers.
A facade, riser, common duct, ceiling void, window panel or other common-property element must not be treated as an available discharge route from a generic assumption. The property owner, landlord, MCST or relevant building party may need to confirm the actual route, alteration and approval requirements before work.
Ventilation can be one part of moisture control. Active water leaks, waterproofing defects, condensation, blocked ducts, insufficient makeup air and cleaning or mould treatment are separate problems; this page does not promise that a fan replacement will resolve them.
Toilet exhaust fan replacement FAQ
How much does toilet exhaust fan replacement cost in Singapore?
There is no responsible fixed S$ price before the existing fan, opening, mounting, duct, electrical point and access are checked. The quote should name the supplied or customer-supplied model, removal, fitting, electrical boundary, access equipment, testing, disposal, exclusions, planned attendance basis and written warranty terms if any.
Can a different-size exhaust fan replace the old one?
Only after the existing opening, wall or ceiling material, mounting support, clearances, duct connection, fan rating and electrical requirements are checked. Enlarging or reducing an opening, adding a frame, altering finishes or changing the duct is separate builder's or installation work and is not implied by replacement.
Is electrical wiring included with exhaust fan replacement?
Only the electrical work expressly listed in the accepted quote is included. A compatible connection at a suitable existing point is different from a new point, rewiring, switch alteration, circuit repair or testing; regulated electrical work is routed to an appropriately Licensed Electrical Worker where required.
Does replacement include a new duct or external vent?
No, unless the accepted quote identifies the full permitted duct route, diameter, length, bends, supports, grille or louvre, damper, access, penetrations, sealing and approvals. A fan must not be assumed able to discharge into a riser, ceiling void, facade or common-property route without site and building confirmation.
Will a new exhaust fan stop mould, dampness or odour?
A suitable operating fan may improve air movement when the room has an effective permitted air path, but it does not guarantee removal of mould, odour or condensation. Waterproofing, leaks, cleaning, blocked ducts, makeup air, room use and building ventilation may need separate investigation.
Are old-fan removal and disposal included?
Only when the quote lists safe removal, access, cart-away and disposal. Fragile ceilings, inaccessible fixings, asbestos or other hazardous-material concerns, duct cleaning, making good and disposal restrictions require a separate approved method or specialist scope.
How long does toilet exhaust fan replacement take?
The planned duration depends on compatibility with the existing opening and point, ceiling or wall access, duct condition, mounting support, electrical scope, building approvals and model availability. Attendance and completion timing are confirmed only after photos, measurements, product details and the accepted quote are reviewed.
