Exhaust fan prices in Nepal (2026)
The exhaust fan itself is usually the smaller half of the job. A 4-inch bathroom exhaust fan costs Rs 1,500–3,500 for basic models and Rs 3,000–5,500 for silent branded units such as Khaitan Silent, Havells Ventil Air or Crompton. Kitchen 6-inch and 8-inch fans run Rs 3,000–8,000, while heavy-duty or ducted exhaust for large kitchens and commercial toilets lands at Rs 6,000–12,000. Plastic-body budget fans start under Rs 1,200 but yellow and crack within a couple of Kathmandu summers.
Buy for the space: a bathroom only needs air change, not jet-engine airflow — a quiet 4-inch unit at moderate CFM beats a loud cheap one. A kitchen over a gas hob wants higher CFM and a grease-tolerant blade. SDR Smart Design and Repair stocks common sizes and can supply-and-fit or fit the fan you buy, with an itemised NPR quote on 9801508528.
- Basic 4-inch bathroom fan: Rs 1,500–3,500
- Silent branded 4-inch: Rs 3,000–5,500
- Kitchen 6-inch fan: Rs 3,500–6,500
- Kitchen 8-inch / high-CFM: Rs 5,000–8,000
- Heavy-duty or ducted unit: Rs 6,000–12,000
- Budget plastic body: under Rs 1,200 (short lifespan)
Replacement labour and total cost
Replacing an existing exhaust fan — same hole, same cable, old unit out and new one in — costs Rs 800–1,800 in labour in Kathmandu. That includes isolation at the switch or MCB, removal, termination, mounting, a run test and cleanup. The all-in cost for a typical bathroom replacement with a mid-range fan is therefore Rs 2,500–5,000. Kitchen fans with larger bodies and grills sit around Rs 4,500–9,000 all-in.
If the old fan died because its cable or switch failed, diagnosis and repair add Rs 500–1,500 depending on what testing finds. Scorched terminals and melted plugs are common on fans that have rattled for years — when we see that, the point gets rewired, not just the fan swapped. SDR quotes labour and parts as separate lines so you see exactly what you paid for.
- Like-for-like replacement labour: Rs 800–1,800
- Bathroom all-in (fan + labour): Rs 2,500–5,000
- Kitchen all-in (6–8 inch): Rs 4,500–9,000
- Faulty switch/wiring repair: +Rs 500–1,500
- Old-unit disposal included on SDR jobs
When you need a new hole or a new point
Moving an exhaust fan or adding one where none existed changes the price. Cutting a new 100–150 mm hole through a brick or RCC wall costs Rs 1,000–2,500 with cleanup; running a new electrical point to that hole adds Rs 700–1,500 for cable, switch and labour, more if the route crosses a finished ceiling. A duct route to an external wall for kitchen exhaust adds Rs 1,500–4,000 for ducting and brackets.
Plan placement before cutting: exhaust fans should sit high on an external wall or the window above the moisture source, with the discharge clear of the neighbour’s window line. Poor placement is the number-one reason we get called back to move a fan someone installed themselves. SDR marks the route, checks for hidden cable, drills with dust control and seals the penetration properly against monsoon rain.
- New wall hole (100–150 mm): Rs 1,000–2,500
- New electrical point to fan location: Rs 700–1,500
- Duct run to external wall: Rs 1,500–4,000
- Window-mounted fan fit: Rs 600–1,500
- Rain-seal and exterior grill: Rs 500–1,200
Replacement checklist: before the electrician arrives
A little preparation keeps the job inside one visit. Confirm the fan size of the existing cut-out (measure the hole, not the grill), decide whether you are reusing the old point or adding a switch, pick the new fan or ask SDR to supply one, and make sure the bathroom or kitchen is clear around the work area. If the old fan still runs intermittently, note when it fails — that points to a failing capacitor versus a dying motor.
On the day, we isolate the circuit, test before touching, swap the unit, run it on all speeds, confirm the backdraft grill moves freely and clean up. Expect the visit to take 30–60 minutes for a like-for-like swap. Kathmandu-wide call-outs: 9801508528.
- Measure the existing hole diameter
- Decide: reuse point or add a new switch
- Have the replacement fan on site, or request supply
- Clear the wall area and note the MCB location
- Mention any past sparking, smell or intermittent running
