Doors and gates in Singapore: main doors, HDB gates, bedroom and bathroom doors compared

Qanvast, summarising HDB's MyNiceHome information on new BTO fittings, notes that newer BTO flats moved from a timber-veneered main door to a laminated timber door described as more durable and scratch-resistant.

If your door is on a fire escape route, the replacement must be half-hour fire-rated with a fire-rated frame and door closer, so buy from a supplier who can show certification for the door set. The door usually carries a label near the hinges or frame showing its fire rating, which SCDF suggests checking. Do not add glass panels, cut-outs or non-certified hardware to a fire-rated door.

Veneer gives the warmth of timber without the weight and movement of a solid slab. In an open HDB corridor, sun and rain can fade the lacquer, so ask about the finish system and how it is maintained. Laminate is the lower-maintenance choice if your door faces strong afternoon sun. As with any main door, check whether your unit needs a fire-rated replacement before ordering.

Solid timber moves with humidity, so a door that fits perfectly in a dry week may stick in the wet season. Choose a well-seasoned, stable species and a proper sealer on all faces, including the top and bottom edges. For HDB units on a fire escape route, a solid timber door is only acceptable if it is part of a certified half-hour fire-rated door set.

Qanvast notes that newer BTO flats swapped older wrought iron gates for black steel gates with cleaner lines and an inside thumb-turn knob. Most "wrought iron" style gates sold today are steel with decorative work, and laser-cut panels (patterns or your unit number) are a popular upgrade.

Rust is the enemy. Ask for proper surface preparation and powder coating, and touch up chips quickly. HDB's home care guide covers fixing gate bolts that cannot slot or retract properly. When replacing a gate, Qanvast's summary of HDB guidance says it should not obstruct public escape routes and should keep the same width and number of panels as the original, so confirm the details with your contractor and HDB.

Aluminium is a sensible choice in open, rain-exposed corridors where steel would need frequent repainting. Ask about the wall thickness of the profiles and the lock reinforcement, since a light gate should still feel secure. Slatted or perforated aluminium gates give privacy and airflow, which some owners prefer when the main door is left open for ventilation.

Hollow-core doors are fine for storerooms and rooms where noise is not a concern. For bedrooms, especially where someone works from home or a baby sleeps, a solid or semi-solid core is noticeably quieter. If you choose hollow core, ask for a solid block in the lock and hinge areas so handles and hinges stay firm.

For most bedrooms, a semi-solid laminate door is the best value. Swapping a bedroom door in the same position is a straightforward replacement, but moving a door opening needs an HDB permit and the new opening cannot be made through a reinforced concrete wall, according to HDB's MyNiceHome guide. Fit a door stopper and soft-close or quiet latch if the door is close to a sleeping area.

Qanvast notes that sliding doors need no swing clearance but their tracks may need regular maintenance, and one panel stays closed at any time, which can limit access for mobility aids. Sliding glass doors (including fluted glass) are popular for separating open kitchens from cooking fumes. Check the wall beside the opening can take the rail fixings, and that switches or sockets are not where the door will slide.

Qanvast notes pocket doors maximise floor space but can come off their track or become noisy, and repairs may require removing the door to reach the track. Because the door needs a cavity, it is usually built into a new partition wall, which means planning it at layout stage. Ask for a good-quality track system with soft-close and an access method for future repairs.

Qanvast describes bi-fold doors as two panels folding into each other, leaving the opening unobstructed. They are common in HDB bathrooms because they cope with tight corridors. Choose water-resistant panels (PVC, ABS or aluminium-framed) rather than wood-based boards, and ask whether replacement hinges, guides and rollers are available.

Qanvast notes owners can generally change the toilet door frame as long as it is not part of a structural wall. Check with your contractor before changing the opening.

Slide-and-swing doors suit narrow HDB corridors where a full swing door would hit a wall or another door. Ask whether the hardware is aluminium or stainless steel, whether replacement rollers are available, and for a demonstration of the mechanism before buying. Aluminium-framed versions with louvre or frosted panels are common and stand up well to bathroom humidity.

A swing door is the most robust bathroom door if there is room for it. Qanvast notes louvre doors (with gaps between blades) help ventilation and reduce moisture buildup, which suits bathrooms without a window. Avoid ordinary laminate on particleboard for bathroom doors; swollen bottom edges are a common complaint in older flats. Ask for the bottom edge to be sealed and for stainless steel hinges.
