Price of an
interior door.

We went through all the interior door lines in our 2024-2026 quotes: 93 priced lines, spread over 40 quotes for flats and houses. Each quote counts only once per category, so that a home with ten doors does not weigh more than a studio. The prices include the door, its frame, basic ironmongery and fitting.

The size that comes up in 29 of these quotes is a leaf 83 cm wide by 2.04 m high; the 73 and 93 cm leaves each appear in 4 quotes. Varnish-finish oak appears in only two quotes, at €595 excl. VAT: too few to draw a range. The last two lines of the table also rest on few quotes: read them as markers, not as averages.

An entrance door, insulating and secure, falls under a completely different budget: we have detailed it in our guide to the price of a fitted entrance door. Both are part of our series on windows and doors, brought together in the general guide Changing your windows and doors.

The core is the inside of the leaf. A hollow core, a honeycomb held between two facings, gives a light and economical door: this is the standard door set in our quotes. A solid core makes the door heavier, more rigid and better at muffling noise from one room to the next. We offer it for bedrooms and offices; at the median, it costs about a hundred euros excl. VAT more per door.

The frame, fixed in the partition, must match the thickness of the finished wall. Our quotes cite frames 72 to 98 mm deep, depending on the partitions encountered. When the wall is thicker than the frame, a lining or a suitable frame must be allowed for: it shows when dimensions are taken, not in the catalogue.

The finish, lastly. A ready-to-paint or pre-painted door is painted on site, at the same time as the walls: allow €100 to €160 excl. VAT per door in our quotes, as our guide to the price of painting per m² indicates. Decorative ranges arrive finished from the factory, hence their higher price. As for ironmongery, a set of handles on rose plates most often comes to €70 excl. VAT fitted per door (€50 to €95 excl. VAT depending on the model, across 7 quotes), with a privacy-lock rose for the WC and the bathroom.

If the existing frame is sound, plumb and a standard size, only the leaf can be replaced. As soon as the frame is damaged or out of square, or the opening is to be widened, the complete door set is needed. Our quotes then include removal of the old set, around €45 excl. VAT per door across the four quotes that price it separately, followed by fitting of the new one and plaster touch-ups.

The finishes around the frame are the item most often forgotten: filling, tape, repainting the wall. They sort themselves out when the doors are part of a broader renovation of the rooms, the kind described in our guide to redoing walls and ceilings. The same logic applies to floors: a new covering thicker than the old one means trimming the bottom of the doors, a line that our flooring quotes include from the start.

A sliding door needs a free stretch of wall along its travel, with no switch or radiator. A pocket door, which slides away into the partition, means rebuilding the partition around a frame: our quotes include no interior pocket door, so we give no price for it.

In a new home, the order of 24 December 2015 on accessibility requires interior doors to have a minimum nominal width of 0.80 m, corresponding to a clear opening of at least 0.77 m, and 0.90 m for the entrance door. These rules apply to construction; in renovation, they remain a good benchmark, especially if you want a home that is easy to live in as you age. The clear opening is the width actually free once the door is open: that is the one to measure.

With mechanical ventilation (VMC), fresh air enters through the living rooms and leaves through the kitchen, bathroom and WCs: it must be able to pass under closed doors. DTU 68.3, as summarised by the Fédération française du bâtiment, specifies a gap of 1 cm under the doors of bedrooms, bathrooms and WCs, and 2 cm under those of the kitchen, living room and hallways; with natural ventilation, these gaps go up to 2 and 3 cm. A door fitted flush with a new floor cuts this circuit: our salaried joiners set this clearance when fitting.

In a home completed more than two years ago, fitting interior doors falls under 10% VAT, like other interior joinery; in new build, it is 20%. The 5.5% rate does not apply to them: it is reserved for energy-saving works. Our guide to the VAT rate on works details the conditions and the certificate to be provided.

For a standard door painted on site, add the door set and the painting: €500 to €660 excl. VAT taking the most frequent ranges, €400 to €500 for the door and €100 to €160 for the painting. A five-door flat therefore comes to €2,500 to €3,300 excl. VAT, or €2,750 to €3,630 incl. VAT at 10%, excluding removal and plaster touch-ups.
