For interior doors in rental properties, it is important to choose the right option from several types based on the installation location. They are an important fixture that affects both tenant usability and the overall impression of the property. In this article, we explain interior door types, how to choose them, and typical renovation costs in detail.
What types of interior doors are recommended for rental properties?
Interior doors can generally be divided into three main types: hinged doors, sliding doors, and folding doors. Understanding the features of each will help you choose the most suitable door.
Hinged door
This is the most common type and is used at entrances to living rooms, toilets, and bedrooms. It opens and closes by pushing or pulling the door handle.
- Single-swing type：A standard type in which one door panel opens and closes
- Uneven double-door type：Two door panels of different sizes create a wide opening and make it easier to move large furniture and appliances
Its key feature is high airtightness, but it requires space in front and behind the door for opening and closing.
Sliding door
This type opens by sliding the door sideways and is used in living rooms, Japanese-style rooms, and storage areas.
- Single sliding type：A standard type in which one door panel slides sideways
- Center-opening type：Two door panels slide apart to the left and right. This allows for a wide opening width
- Bypass sliding type：Two door panels open and close by overlapping each other. They can be opened and closed from either side
Because the door can be stored along the wall while left open, it is ideal for spaces that are intended to stay open. It is also attracting attention as a barrier-free option.
Folding door
This type opens and closes while folding and is commonly used for closets and storage doors. Its advantage is that it requires the least amount of space when opening and closing. It is available in two-panel and four-panel versions, allowing selection based on the width of the opening.
What material options are available for interior doors?
Choosing the material is also an important point for interior doors. It is best to consider the balance between cost and durability.
Wooden door
Wooden doors made from solid wood create a warm atmosphere. They offer a premium feel, but the price tends to be higher, and care is needed to prevent warping caused by humidity.
Decorative sheet door
This is a door with a decorative sheet applied to a plywood or MDF core. It is the most commonly used type in rental properties, offering an affordable price and a wide range of design variations.
Door with glass panel
This option is suitable for areas where you want to increase natural light. When installed between the living room and hallway, it can bring natural light into the hallway. If privacy is a concern, choose frosted glass.
What points matter most when choosing interior doors?
Below are the main points to prioritize when selecting interior doors for rental properties.
Choose according to the installation location
The appropriate door type differs depending on where it will be installed.
| Installation location | Recommended type | Reason |
|---|---|---|
| Living room entrance | Hinged door / sliding door | Balance between airtightness and openness |
| Toilet | Hinged door | Airtightness and privacy |
| Closet | Folding door | Space-saving and can open fully |
| Japanese-style room | Sliding door | Matches a Japanese aesthetic |
| Washroom | Sliding door | Does not interfere with traffic flow |
Barrier-free accessibility
If the property is intended for older residents or wheelchair users, a step-free sliding door is recommended. With a top-hung sliding door, there is no need for a floor rail, which also reduces the risk of tripping.
Soundproofing performance
In places where sound insulation is important, a hinged door with minimal gaps is suitable. Soundproofing can be improved by attaching a rubber gasket to the bottom of the door.
Design and consistency
Choosing a design that matches the overall image of the property can significantly improve impressions during viewings. Using the same series throughout is recommended.
What is the typical cost range for interior door renovation?
Costs vary depending on the type of door and the scope of work. Below are common cost benchmarks.
Door replacement costs
| Work details | Estimated cost |

| Replace hinged door (door body + frame) | JPY 50,000 to 150,000 |

| Replace folding door | JPY 50,000 to 120,000 |
| Change from hinged door to sliding door | JPY 100,000 to 250,000 |
Partial door repairs
In some cases, partial repairs may be sufficient instead of full replacement.
- Replace door knob：JPY 5,000 to 15,000
- Replace hinges：JPY 3,000 to 8,000
- Replace decorative surface sheet：JPY 20,000 to 50,000

Tips for controlling costs
Costs can be managed more efficiently by carrying out the work together with move-out renovation work. It is also important to obtain quotes from multiple companies.
What should you keep in mind when replacing a door?
Here are the main points to watch when carrying out a door replacement renovation.
Compatibility with the existing frame
If the existing door frame will be reused, it is necessary to confirm that the new door size matches the frame. If the frame is replaced as well, wall repairs will also be required, which can significantly affect the total cost.
Compliance with fire regulations
Doors facing shared hallways may be required to be fire-rated. Before proceeding, check the requirements of the Building Standards Act and fire regulations.
Advance notice to tenants
Because the work will generate noise, tenants should be notified in advance. Be clear about the construction schedule and the expected duration.
Frequently Asked Questions (FAQ)
How long do interior doors typically last?
In general, 15 to 20 years is a common guideline. In high-use areas, deterioration can happen sooner, so if hinges become loose or the door becomes warped, it is worth considering replacement.
Is it possible to change a hinged door to a sliding door?
It depends on the wall structure and the location of plumbing, but in many cases the change is possible. It is advisable to request an on-site inspection from a contractor in advance.
Does door design affect occupancy rates?
It has a major effect on first impressions during viewings. In particular, the living room entrance door is highly visible, so replacing it with a well-designed door can be a renovation with strong cost-effectiveness.
Can you replace a door as a DIY project?
Tasks such as replacing a door knob can be handled as a DIY project, but replacing the door body itself requires fitting adjustments, so hiring a specialist is recommended.
