HDB Interior Design Singapore: Laundry Corner Electrical Planning
HDB interior design Singapore laundry corners fail most often on the electrical plan, not the look. A recent HDB trend places the washer and dryer inside the kitchen or a service yard of 4-room and 5-room flats, where the power load must follow SP Group rules. Good electrical planning keeps your HDB renovation permit clean and your machines safe.
Where HDB interior design places the laundry corner
Most HDB flats give you a service yard or a kitchen wet area for the laundry. A 4-room flat is about 90 sqm and a 5-room about 110 sqm, so the yard is often 1.5m by 2.0m. That space must hold the washer, a dryer or rack, and the points without feeling cramped. Practical HDB interior design Singapore puts the laundry where the water and power already run, not where it looks nice in a render.
Keep the laundry off the bomb shelter. The shelter stays untouched except for light fittings and laminated flooring, with the door in place, so do not run a washer point there.
Count the power points you need
A laundry corner draws more than owners expect. List each load before the drawings:
- Washer: a 13A socket on its own circuit, typically 2.0kW to 2.5kW.
- Dryer: a second 13A socket, another 2.0kW to 2.5kW if vented or heat-pump.
- Water heater for the adjacent bath: a 3.6kW instant unit needs its own isolated point.
- Utility light and a ventilation fan on the lighting circuit, not the power circuit.
SP Group rules govern the total amperage per circuit, so your HDB Licensed Renovation Contractor in the Directory of Renovation Contractors must balance the loads.
Step-by-step electrical plan
Work through these steps with the contractor before the HDB renovation permit is filed:
- Mark the machine centres and leave 50mm clearance on each side for airflow.
- Set sockets at 1200mm height so cords do not dip into the floor water.
- Run the washer and dryer on separate 15A or 13A radial circuits, not a ring.
- Add a waterproof socket cover rated for the wet area near the washer.
- Place the fan isolator switch outside the wet zone for safe maintenance.
Permit, timing and contractor rules
An HDB renovation permit is required before works begin, and processing takes about 2 weeks. Declare the new power points in the permit so the electrical works are covered. Only HDB Licensed Renovation Contractors may do the wiring.
Structural elements such as load-bearing walls, beams, columns and slabs cannot be hacked. Run conduits on the surface or in shallow chases approved by HDB, never through a beam.
Water and floor details
Use HDB-approved vinyl or laminate flooring with a water-resistant core in the yard, and slope the floor to the drain so spills leave fast. Quartz or solid-surface countertops suit a fold-down ironing ledge above the machines.
For HDB flat space saving, stack the washer and dryer and build a pull-out lint drawer below. A cantilever table beside the machines gives a folding spot without a fixed table.
Noise and drying rules
Noisy works like hacking and drilling are allowed only on weekdays from 9am to 6pm, with none on Sundays or public holidays. Schedule the conduit chase and socket fit during those hours.
Dry clothes on the rack when the yard allows; a heat-pump dryer avoids the balcony enclosure issue, since newer BTO flats around 2019 onward include balconies that HDB does not allow to be enclosed.
Cost framing for the electrical work
Market ranges put a 4-room BTO renovation around S$30,000 to S$45,000 and a resale around S$50,000 to S$70,000 because of more hacking and rewiring. Treat these as market ranges, not fixed quotes, and budget the laundry electrical as a focused slice.
Plan the laundry before you build
A laundry corner planned on paper first avoids tripped breakers and wet-floor shocks later. Right points, right height, right circuit balance, all inside the HDB permit, give you a yard that works every wash day. Solid HDB interior design Singapore treats the laundry as a working utility, not a showpiece.
If you want the electrical and carpentry drawn as one, our whole-house customization team can lay out your laundry corner to SP Group and HDB rules, then build it so the machines just plug in and run.
