This article explains the different types of HDB doors available today, their materials, sizes, and functions — helping homeowners better understand their choices before renovation or replacement.
Standard HDB Bedroom Door Size
The standard HDB bedroom door size is usually 3 feet wide by 7 feet high (3ft x 7ft) with a thickness of around 35mm.
However, newer BTO flats may come with wider or tallaer doors. If your doorway does not follow the standard size, custom doors may be required, which can involve extra costs.
Types of HDB Bedroom Doors
1. Hollow-Core Bedroom Doors
Hollow-core doors are lightweight and budget-friendly. Inside, they contain a honeycomb-style structure made from plywood or cardboard, which helps maintain basic strength while keeping the door light.
These doors are easy to install and are often wrapped with veneer or laminate for appearance. Because the inside is mostly empty, hollow-core doors offer minimal sound insulation but are suitable for homeowners looking for a more affordable option.
2. Semi-Solid Core Doors
Semi-solid core doors provide a good balance between price and performance. They are filled up to about 70%, making them heavier and sturdier than hollow-core doors.
The outer layer can be laminate, veneer, or nyatoh. These doors offer better sound reduction and temperature control while still being reasonably priced. Many HDB homeowners choose semi-solid doors for bedrooms due to their improved strength and comfort.
3. Solid Core Doors
Solid core doors are fully filled, usually with plywood. They offer the best soundproofing and durability among bedroom door types.
These doors feel more premium because of their weight and structure. While they cost more than hollow or semi-solid doors, they are still more affordable than full solid wood doors.
Solid core doors are commonly used for fire-rated HDB doors & Guidelines, which are important for safety. Fire-rated doors help slow down fire spread and allow occupants more time to escape during emergencies.
4. Laminate Doors
Laminate bedroom doors are highly popular in HDB homes due to their durability and easy maintenance. They come in many designs, colours, and textures such as wood grain or matte finishes, making them a great choice for modern interiors while offering good resistance to scratches and moisture.
Types of HDB Main Doors in Singapore
The main door is the first thing people notice when entering your home. In HDB flats, main doors are usually made using laminate or wood, offering both style and everyday practicality. Today’s HDB main doors come in many designs to suit different interior themes.
Single Tone
Single tone main doors feature one consistent colour across the entire surface. This clean and simple look works well for modern HDB homes and blends easily with most interior designs.
Two Tone

Groove Line Design
Groove line doors include subtle lines carved into the surface, adding texture and depth. These designs give a contemporary feel without being too bold, making them suitable for minimalist interiors.
Stainless Steel Strip Design
SS strip main doors feature slim stainless-steel inlays that add a modern touch. The metal detailing enhances the overall appearance while keeping the door sleek and refined.

Types of HDB Kitchens Doors
Choosing the right kitchen door helps separate cooking areas while keeping your home bright, clean, and space-efficient. In HDB flats, kitchen doors are often selected based on space, airflow, and ease of use.
Kitchen Sliding Door

Types of HDB Sliding Doors in Singapore
Sliding doors are a popular choice in HDB homes because they save space and suit modern interiors. They are commonly used for bedrooms, kitchens, wardrobes, and study areas. Different sliding mechanisms offer different looks and functions.
Ghost Sliding Door

Concealed Track Sliding Door
