Choosing tiles for a renovation may seem like a simple decision, but in reality, it can completely define the final result of a home. The colour, format, finish, type of material and use of each room all influence both the aesthetics and the functionality of the space.
One of the most common mistakes is focusing only on the design. It is normal to fall in love with a tile because of its colour or texture, but before making a decision, it is important to think about where it will be installed, how that area will be used and what maintenance it will require over time.
Today, there are many types of tiles: porcelain, ceramic, hydraulic-style, stone effect, wood effect, terracotta effect, marble, cement or decorative pieces. Each one creates a different feel, and not all of them work equally well in every room.
That is why, before choosing, it is important to avoid some common mistakes that can affect the final result of the renovation.
Choosing tiles only for their appearance
The first mistake is focusing only on whether a tile looks beautiful. Aesthetics are important, but they should not be the only criterion.
A tile can look spectacular in an inspiration image, but it may not work the same way in your home. Natural light, the size of the room, the style of the furniture and daily use can completely change the result.
For example, in a kitchen, it is not only important that the wall tile matches the furniture. It should also be practical, easy to clean and resistant. At Ondacer, we explain that porcelain tiles are one of the most recommended options for modern kitchens due to their resistance to stains, humidity and temperature changes.
The ideal approach is to find a balance between design and functionality. A good tile should match the style of the home, but it should also respond well to the real use of the space.

Not taking the use of each room into account
Another very common mistake is choosing the same type of tile for everything without considering the needs of each area.
A kitchen, a terrace, a living room or a hallway do not have the same use. In high-traffic areas, it is best to choose resistant materials. For outdoor spaces, it is also important to consider durability, low water absorption and anti-slip finishes. Ondacer recommends porcelain tiles designed for outdoor use because of their resistance, low absorption and suitable finishes for terraces, patios and swimming pools.
Indoors, however, you can play more with decorative finishes, large formats, reliefs or natural textures. The key is to choose the material according to the space, not just according to the trend.
A beautiful floor can lose functionality if it is not designed for everyday use. That is why, before buying, it is worth asking whether the tile will be used on the floor or wall, whether it will be in contact with humidity, whether it will have heavy foot traffic or whether it will be installed indoors or outdoors.
Choosing a format that does not suit the space
The tile format also has a strong influence on visual perception.
Large formats can help create cleaner and more continuous surfaces, especially in modern homes or open spaces. By reducing the number of joints, the result looks more organised and spacious.
On the other hand, small or decorative formats can add a lot of character to specific areas, such as kitchen fronts, splashbacks or feature walls.
The mistake is choosing a format without considering the size of the room. In a small kitchen, for example, light tones and well-proportioned formats can help create a greater sense of spaciousness. Ondacer highlights that light colours such as white, beige, light grey or pastel shades reflect light better and create a feeling of cleanliness and openness.
Therefore, it is not about always choosing large tiles or always choosing small pieces. It is about choosing the format that best suits the space.

Not thinking about continuity between spaces
In a renovation, each room should not be chosen as if it were completely independent. The overall look of the home also matters.
One of the most common mistakes is mixing too many materials, colours or styles. This can make the house feel less organised and more visually overloaded.
Using the same flooring in several areas can create continuity, spaciousness and a sense of coherence. This works especially well in open-plan living rooms, integrated kitchens or modern-style homes.
Wood-effect porcelain flooring is an interesting option when you want warmth and continuity without giving up the resistance of ceramic. Ondacer highlights that this type of porcelain tile recreates the grain and tones of natural wood, allowing you to create cosy spaces with a resistant, practical and low-maintenance floor.
Choosing the right flooring for a renovation is not just about thinking of one room, but about imagining how the entire home will look.
Choosing colours without considering natural light
Colour can completely change the feeling of a room.
Light tones usually bring brightness, spaciousness and a sense of cleanliness. They are a good option for small kitchens, interiors with little light or spaces where you want a timeless result.
Dark tones, on the other hand, can add elegance and depth, but they should be used carefully if the room is small or has little natural light.
It is also important to remember that the colour of a tile can change depending on the light. A piece may look warmer or cooler depending on the orientation of the home, the artificial lighting and the furniture around it.
That is why, before choosing, it is advisable to look at the product carefully, compare shades and think about the renovation as a whole.
