In the pursuit of personalized spaces and premium living, mass-produced furniture often falls short of capturing the true essence of a home.
As modern minimalism and light luxury styles continue to dominate global design trends, high-end custom furniture has become the absolute core of creating an ideal living space.However, the custom furniture market can be highly complex.
Bridging the gap between a stunning design blueprint and the final product involves navigating materials, hardware, and craftsmanship. Here is how to choose bespoke luxury furniture like a professional designer.
Doors do more than close off a room. In villa, hotel, and commercial projects, door specification affects acoustic comfort, fire safety, daily maintenance cost, and how consistent hundreds of rooms feel across an entire development.
Quick Answer
A good door specification balances four things: acoustic performance, moisture resistance, fire compliance, and finish consistency — all shaped by the room's function and the project's scale. The right combination depends on where the door sits in the building, not just what it looks like.
Door Types by Application
Rather than listing door types at random, it helps to group them by what they’re actually solving for — sound, moisture, fire safety, space, or a specific project setting.
Flush Doors
Flat-faced doors with no raised panels — the global default for contemporary hotel corridors, villa bedrooms, and residential developments.
Panel Doors
Traditional doors with raised or recessed panels, reserved for heritage renovations and classical villa interiors.
Function & Moisture Resistance
WPC Doors
Resist moisture and pests without timber’s maintenance burden — the practical standard for bathrooms, kitchens, and tropical-climate projects.
Solid Wood Doors
The highest-prestige finish, reserved for statement entries and premium interiors where budget supports upkeep.
Aluminium Doors
Fully waterproof and durable — suited to wet back-of-house areas, coastal projects, and large sliding/folding systems.
Fire-Rated Doors (FD30/FD60)
Non-negotiable for hotel corridors and stairwells, tested against codes such as BS 476 or ASTM E152.
Space-Saving & Project-Specific
Sliding & Pocket Doors
Space-efficient options for compact bathrooms and open-plan layouts where a swinging door isn’t practical.
Bifold Doors
Common in premium wardrobes and closets, folding flat to maximize usable floor space.
Transom-Topped Doors
Entry and hallway doors paired with a window above, adding daylight and architectural height to foyers.
Hotel Guest Room Doors
Solid-core, fire-rated, and acoustically tested as standard — the specification with the least room for error at scale.
Key Factors When Specifying Doors for Projects
Before finalizing door specifications for a villa, hotel, or commercial project, work through these eight factors:
| Selection Factor | Why It Matters | Recommendation |
|---|---|---|
| Room Function & Acoustic Need | Different rooms require different levels of sound insulation and durability. | Use solid-core, higher-STC doors for bedrooms and suites; hollow-core doors are suitable for storage rooms and utility spaces. |
| Moisture Exposure | High humidity and water exposure can damage untreated timber doors. | Choose WPC or aluminium doors for bathrooms, kitchens, laundry rooms, and tropical climates. |
| Fire Compliance | Many commercial and residential buildings must meet fire safety regulations. | Install certified fire-rated doors in corridors, stairwells, and emergency egress routes according to local building codes. |
| Local Building Codes & Standard Heights | Door dimensions and installation standards vary by country and region. | Confirm local code requirements and standard door sizes before design and production. |
| Unit Consistency (mm vs inch) | Mixing metric and imperial measurements can lead to costly production errors. | Verify whether all drawings and specifications use millimeters (mm) or inches before manufacturing begins. |
| Hardware & Cycle Rating | Hinges, locks, and other hardware determine long-term performance. | Select hardware rated for 50,000+ operating cycles to support approximately ten years of hotel-grade daily use. |
| Batch Consistency at Scale | Color variation becomes much more noticeable on large projects. | Maintain a Delta E ≤ 1.5 color tolerance to ensure consistent appearance across 100+ doors. |
| Budget & Lead Time for Custom Sizes | Non-standard dimensions and special certifications increase complexity. | Plan additional budget and production time for custom heights, widths, or fire-rated door requirements. |
Door Sizing & Standard Dimension
Door sizing actually involves two separate measurements that are easy to confuse: the door slab size (the physical panel itself) and the rough opening (the larger framed wall space the complete unit needs to fit into).
| Quick Reference — Standard Interior Door | Typical Range |
|---|---|
| Slab width | 600–910 mm |
| Slab height (most common) | 2040 mm |
| Rough opening allowance | +50 mm W / +65 mm H |
| Regional height range | 2032–2100 mm+ |
For villa and hotel projects, standard heights vary more by region than people expect — confirming which convention a project follows (2032mm US, 2040mm Australia, 2100mm+ Middle East) before framing begins avoids a costly rework later.

Door Materials & Core Types
| Type | Best For |
|---|---|
| Flush door (solid core) | Hotel guest rooms, bedrooms — global standard for acoustic feel |
| WPC door | Bathrooms, kitchens, tropical-climate projects |
| Solid wood door | Premium statement entries |
| MDF door | Budget-conscious dry interior spaces |
| Aluminium door | Wet back-of-house, coastal, large sliding/folding systems |
| Reference Spec — Hotel Guest Room Door | Typical Minimum |
|---|---|
| Leaf thickness | 45 mm |
| Acoustic rating | STC 30+ |
| Fire rating (egress routes) | FD30 |
| Hinge cycle rating | ≥ 100,000 |
| Batch color tolerance | Delta E ≤ 1.5 |
Custom Door Sourcing for Large-Scale Projects
Standard door sizes and specifications don’t always fit villa, hotel, or commercial builds — especially with non-standard ceiling heights, fire compartmentation requirements, or design-led architecture.
FAQS
What type of door is best for a hotel guest room?
Solid-core flush doors are the global standard, typically specified with a minimum 45mm leaf thickness, STC 30+ acoustic rating, and FD30 fire rating on egress routes.
What's the difference between a flush door and a WPC door?
Flush door describes a construction method — a flat-faced door built around a core. WPC describes a specific core material. A flush door can have a WPC core, a timber core, or several other core types.
Can interior doors be customized for villa or hotel projects?
Yes. Custom heights, fire ratings, acoustic specs, and finishes are common, particularly where ceilings exceed 2700mm or hospitality brand standards require specific performance.
How do I choose the right door for a bathroom or kitchen?
WPC or aluminium-core doors are the practical standard, since both resist moisture and pest damage far better than solid timber or standard MDF.
What are the latest trends in door design for hospitality projects?
Flush minimalist doors with concealed hardware, wall-flush frameless installations, and matched transom-topped entries are among the most requested specifications.
Do all project doors need to be fire-rated?
No — fire rating requirements are specific to egress routes, corridors, and stairwells. Interior bedroom or living-area doors typically aren't required to be fire-rated unless a brand standard requires it.
Door specification works best when it’s planned alongside the building itself — not chosen room by room after construction begins. For villa, hotel, and commercial projects, aligning door type, core material, and hardware early helps avoid costly changes later.
The safest approach: decide on acoustic, moisture, and fire requirements first, then choose the door types and materials that support them — confirming units and building codes before production begins.
