Interior doors in Brussels: installed prices, types and advice (2026)

In Brussels, an installed interior door generally costs between €300 and €1,500 excluding VAT, depending on the type of door leaf, the frame, and the complexity of the installation. A honeycomb-core door in a standard door frame remains at the lower end of the range; a lacquered solid-core door, glazed door, or pocket sliding door pushes it towards the top. At Akdeniz Deco (Rue de Beughem 18, 1030 Schaerbeek), we offer Group Thys interior doors for sale and installation, with advice coordinated with your floors and skirting boards.

The essentials in 30 seconds

• Standard height in Belgium: 201.5 cm. Common widths: from 63 to 93 cm.
• Supply only: from €50 (honeycomb core) to €800 (solid wood) per door leaf.
• Installation of a complete door frame: approximately €200 to €350 per door.
• 6% VAT possible if the property is more than 10 years old and the door is supplied and installed by the contractor.
• The factor that determines durability: less the brand than the preparation for installation (rebating, finished floor level, gap under the door).

Which type of interior door to choose?

The first choice is not aesthetic, it is technical: what is inside the door. The core of the door leaf determines its weight, its acoustic insulation, its durability over time, and its price.

Our advice: do not put the same door everywhere. A solid core for bedrooms and bathrooms (where noise and privacy matter), a tubular core for the rest, a glazed door where light is lacking. This is often the smartest way to allocate a budget.

Door only or door frame: what should you buy?

Buy a door only (the door leaf) if your existing frame is plumb, in good condition, and the correct dimensions. This is common in Brussels apartments from the 1970s to 1990s: replace the door leaf, change the hinges and handle, and the room changes its look for a limited budget.

Buy a door frame (door leaf + frame + hardware, pre-assembled) as soon as the frame is damaged, out of square, or you are doing major renovations. The door frame guarantees an even gap all around the door leaf, which prevents doors from rubbing or no longer closing after a winter.

How much does an installed interior door cost in Brussels in 2026?

Concrete example: a 2-bedroom apartment in Schaerbeek

Five doors to replace (2 bedrooms, bathroom, toilet, kitchen), frames in poor condition. With five tubular or solid-core door frames and a complete installation, count on around €2,000 to €3,500 excluding VAT for the whole. The budget shifts mainly on two items: the finish (ready-to-use or paint-ready lacquer) and the number of doors that require an opening adaptation.

Does the 6% VAT apply to your doors?

Yes, on two cumulative conditions: your private home is more than 10 years old, and the door is supplied and installed by the same company, which bills you for the whole. If you buy the door only to install it yourself, the VAT remains at 21%. On five doors, the difference easily exceeds several hundred euros: it is a serious argument to entrust the installation to a professional.

Measure well: the standard dimensions in Belgium

In Belgium, the standard height of an interior door is 201.5 cm. The common door leaf widths go from 63 to 93 cm, in 5 cm increments (63, 68, 73, 78, 83, 88, 93 cm). Staying within these standard measurements avoids custom-made, which can multiply the price.

Before coming to the showroom, note three things:

1. The width and height of the opening (the opening in the wall, without the frame), measured at three points.
2. The thickness of the wall: it determines the rebate (the part of the frame that covers the thickness of the wall). This is the most often forgotten point, and the first source of bad surprises at the time of installation.
3. The direction of opening: stand on the side where you push the door to open it. If the hinges are on the right, it is a "right pushing" door; on the left, "left pushing".

Sliding door: surface-mounted or pocket?

Surface-mounted, the rail is fixed above the opening and the door slides along the wall. It is quick to install, without work, but you need a free wall panel (no switch, radiator, or furniture) and the sound insulation remains limited.

Pocket, the door disappears into a partition. The result is the most streamlined and the wall remains usable on both sides, but you need to open or recreate the partition: to be planned in a renovation, not in a simple replacement.

Group Thys interior doors at Akdeniz Deco

Our Schaerbeek showroom presents the interior doors of Group Thys, one of the main manufacturers of interior doors on the Belgian market. The catalog covers the essentials of a home's needs: ready-to-install lacquered doors, paintable doors, glazed models and sliding doors, in door leaf only or in door frame, in standard Belgian dimensions.

Our position is simple: an entry-level door well installed ages better than a high-end door poorly installed. The problems that we encounter on the ground (door rubbing, frame gaping, rebate peeling off) come most often from insufficient preparation: wall not measured, finished floor not yet installed, humidity in a freshly plastered room. That is why we guide you towards the series adapted to each room, rather than the most expensive.

Doors, floors and skirting boards: the order that avoids rework

This is where a single supplier makes the difference. A door is installed after the floor covering, never before: the height of the door leaf is adjusted to the finished floor. If you change your floor at the same time, coordinate the two jobs:

• First install your tiles, your semi-solid parquet or your vinyl floor.
• Leave a gap of about 1 cm under the door. If your home is equipped with mechanical ventilation (system C or D), this space or a transfer grille is necessary so that air circulates between rooms.
• Finish with the skirting boards, matched to the color of the doors or the floor. Our skirting board cutting service delivers skirting boards at the right length, from the tiles you have chosen.

5 common mistakes to avoid

1. Ordering before the floor is installed: the door will be too long or too short by a few decisive millimeters.
2. Forgetting the thickness of the wall: the standard rebate does not always cover old Brussels walls, which are often thicker.
3. Installing a honeycomb core in a bedroom: saving a few tens of euros, acoustic discomfort for years.
4. Installing in a room that is still damp after plastering or screeding: the wood and MDF swell, then deform.
5. Buying alone then having it installed: you lose the 6% VAT and the guarantee of a single contact in case of a defect.

Frequently asked questions about interior doors

What is the average price of an installed interior door in Belgium?

Count generally between 300 and 1,500 € excluding VAT per door, supply and installation included. A standard tubular core door frame installed is in the lower end of this range; a solid wood, glazed or pocket sliding door in the upper.

What is the standard size of an interior door in Belgium?

The standard height is 201.5 cm and the common widths go from 63 to 93 cm, in 5 cm increments. Sliding doors also exist at a height of 215 cm.

Which interior door insulates the best from noise?

A door with a solid core or solid wood, installed in a door frame with a peripheral seal. A door with a honeycomb core or a surface-mounted sliding door insulates little, whatever its finish.

Can you benefit from 6% VAT on interior doors?

Yes, if the home is more than 10 years old, that it is for private use, and that the door is supplied and installed by the same contractor. The purchase of the door alone remains subject to 21%.

Should you change the frame at the same time as the door?

Not necessarily. If the frame is square, in good condition and standard dimensions, replacing the door leaf is enough. If it is damaged, deformed or out of standard, the complete door frame is more durable and often faster to install.
