Renovating a wall without taking on major construction work is now within everyone’s reach thanks to interior wall décor. 3D wall panels, textured wall coverings, MDF décor and PVC wall panels can transform a living room, kitchen, bedroom or home office with minimal disruption.
But aesthetics are only part of the equation. An incorrectly calculated surface area, a material unsuitable for humid conditions or inadequate mounting can quickly increase the total cost. Here are the key points to check before placing your order, along with a selection suited to different projects.
A pack may contain 20 or 33 pieces without covering a particularly large area. It all depends on the dimensions of each panel. With a 30 × 30 cm model, one panel covers approximately 0.09 m². You should therefore rely on the total surface area stated by the manufacturer and allow extra material for cutting.
For a wall measuring 2.5 m wide by 2.4 m high, the total area is 6 m². A single pack covering 2.97 m² will not be enough, even if the number of panels appears substantial.
The PVC wall panels featured here from Art3d are listed as resistant to water and heat. They may therefore be suitable for rooms exposed to moisture, provided they are installed correctly and the joints are properly sealed.
By contrast, MDF wall décor is generally intended for dry rooms. The Atmosphera Louison model is made from E1 MDF and can be used in a kitchen, dining room or entrance hall. However, it should be kept away from water splashes and cleaned with a dry cloth.
Even a panel marketed as easy to install requires a clean, dry, flat and dust-free surface. Significant irregularities can leave visible gaps between the elements. For 3D panels, you should also choose an adhesive or silicone compatible with the substrate.
If you are installing wall décor in a kitchen or fitting out an interior wall near a sink, check that the wall is in good condition and that areas exposed to splashes are properly protected.
For maintenance, preferably use a soft cloth. Abrasive products may damage a matte black, white or textured finish.
The 30 × 30 cm panels are easy to handle and cut with the right tools. They also make it possible to create regular patterns on a feature wall. Before calculating how many packs you need, measure the wall’s width and height, taking electrical sockets, switches and corners into account.
A geometric wall panel makes a stronger visual impact when the joins are perfectly aligned. Take the time to mark horizontal and vertical guidelines before installation.
Some products include a hanging system, while others require glue or silicone. The Atmosphera Louison décor weighs 1.57 kg, and its wall fixings are not included. Use wall plugs suited to the type of wall and regularly check that the installation remains secure.
If you are renting, also check the rules concerning drilling and any restoration work required under your tenancy agreement.
Why this product is a good match: Its vertical format fits easily into a kitchen, dining room or beside a door. Installation focuses on a single decorative element.
The product details clearly state the dimensions, weight and absence of wall fixings. You can therefore purchase the right wall plugs before starting installation.
E1 MDF, engraved black-and-gold finish, integrated hanging system and 78 × 28 cm format.
Why this product is a good match: Its white finish and geometric relief complement modern wall décor in a living room, office or bedroom.
The stated coverage is 2.97 m² for 33 panels measuring 30 × 30 cm. This makes it easy to calculate how many packs you need.
Rigid PVC described as waterproof, heat-resistant, odourless and recyclable, with installation possible using glue or silicone.
Why this product is a good match: This pack is suitable for feature walls in a bathroom, utility room, office or commercial premises, particularly where easy maintenance is a priority.
The product details state coverage of 1.8 m² for 20 panels. Compare this area with the size of your wall rather than relying solely on the number of pieces.
High-density PVC described as moisture-resistant, recyclable, odourless and easy to cut with standard tools.
Why this product is a good match: The contrast between the matte black finish and the relief creates an elegant feature wall in a living room, bedroom or professional space.
A dark finish makes installation flaws more visible. Measure carefully, align the patterns and dry-fit the panels before securing the full installation.
33 panels measuring 30 × 30 cm and covering 2.97 m², made from rigid PVC described as waterproof and heat-resistant.

When installing around a socket or switch, switch off the power before starting work and use suitable equipment. If you have any doubts about the electrical installation or waterproofing in a humid room, consult a qualified professional.
The PVC models featured are described as water- and moisture-resistant. They may therefore be suitable for a bathroom, provided they are installed on a sound surface and the joints are properly protected. However, they do not necessarily replace a waterproofing system designed for areas directly exposed to water.
Service life depends on the material, the quality of the substrate, the adhesive used, exposure to moisture and maintenance. Rigid PVC generally performs better than MDF in humid rooms. Choosing fixings suited to the wall also reduces the risk of panels coming loose or falling.
A black surface absorbs more light than a white one. To preserve the room’s visual balance, use it on a single wall or as an accent feature. Complement it with sufficient lighting and lighter tones on the remaining surfaces.
