Not enough storage space

One of the most common mistakes is underestimating the space needed for towels, toiletries, or cleaning supplies. Without well-thought-out shelves and storage solutions, the bathroom quickly becomes cluttered. Flexible shelves or shower trays that don't require drilling help create storage space without damaging the tiles. Especially in small bathrooms, it's worth making effective use of niches or corners.

Choosing the wrong materials

Bathrooms are always humid, so materials must be robust and durable. Cheap plastic solutions often quickly become unsightly or wear out. Sturdy metals or powder-coated surfaces are more suitable, as they are moisture-resistant and look good for a long time. This will keep your bathroom not only hygienic but also beautiful over time.

Lack of flexibility

Drilling holes in tiles can be a problem, especially in rented apartments. Choosing the most flexible fixings possible when installing tiles will save you a lot of hassle later on when moving or renovating. Adhesive wall solutions are a simple solution that can also be removed if necessary.

Too little light

Bathroom lighting is often underestimated. A single ceiling light is rarely enough to evenly illuminate the entire room. A combination of ambient light and mirror lighting is better for a completely comfortable feel. Warm white LED light creates a relaxing atmosphere while saving energy.

Unfavorable colour choice

The colour choice in the bathroom also significantly influences how spacious, bright, and inviting the room appears. Small bathrooms, in particular, benefit from light colours and soft contrasts that create a sense of spaciousness. Overly wild colour patterns or dark tiles, on the other hand, can quickly feel overwhelming. If you choose a clear, understated colour and add accents sparingly, your bathroom will remain timeless and be easier to redesign later.

Tiles too dark

Can further reduce the size of small rooms.

Colorful mosaics

Quickly appear restless or overloaded.

No contrasts

Makes the room boring and uninviting.

Mixing too many trends

Quickly makes the bathroom look chaotic.

Cold colours

Often appear sterile and uncomfortable.

Functionality neglected

Even a stylish bathroom needs to be practical. If accessories are mounted too far away or shelves are hard to reach, it can be annoying in everyday life. So think carefully about where you place towels or toiletries so everything is within easy reach. Flexible solutions are especially useful if your needs change later.

Flexibility and durability

Bathrooms are used daily—making it all the more important to consider storage space, quality materials, adequate lighting, and a thoughtful colour scheme when planning. By opting for flexible and durable solutions, your bathroom will not only remain functional but will also become a space where you feel completely comfortable in the long term.

What is the most common mistake in small bathrooms?

Too little storage space and dark colours that make the room seem even smaller.

Do wall solutions without drilling really hold?

Yes, if installed correctly, these systems are very reliable.

Should I always avoid drilling in rented apartments?

If possible, yes – this way damage can be avoided.

Can I retrofit the bathroom lighting?

Sure, modern LED mirror lights are easy to retrofit.

Which colours have a particularly friendly effect in the bathroom?

Light natural tones with warm accents create a cozy atmosphere.
