Bathroom Tiles: 7 Mistakes to Avoid When Choosing Tiles for Floors, Walls and Showers
A bathroom is usually renovated only once every 20 to 30 years. That makes choosing the right bathroom tiles one of the most important decisions in any renovation or new-build project.
A beautiful tile can completely transform a bathroom. However, appearance alone is not enough. Slippery floors, unsuitable tile sizes, poorly matched colours or excessive grout lines can affect the final result and everyday comfort.
Modern porcelain bathroom tiles offer an extraordinary variety of designs, from elegant marble effects and natural travertine to large-format stone-look tiles and colourful decorative wall tiles.
But which tiles are suitable for a bathroom floor? Can large tiles make a small bathroom look bigger? And what should you consider when selecting tiles for a walk-in shower?
In this guide, we explain seven common mistakes and show you how to choose bathroom tiles that combine design, durability and practicality.
Mistake 1: Choosing Bathroom Tiles Based Only on Appearance
Not every beautiful tile is suitable for every part of a bathroom.
Wall tiles are primarily selected for their design, colour and surface. Bathroom floor tiles, however, must also withstand everyday use, moisture and regular cleaning.
The shower area presents additional requirements because water, shampoo and soap can make surfaces slippery.
Before choosing your tiles, it is therefore important to distinguish between the bathroom floor, the walls and the shower.
Why porcelain stoneware is ideal for bathrooms
Porcelain stoneware is one of the most popular materials for modern bathroom tiles.
Manufactured at high temperatures, porcelain tiles have a dense structure and very low water absorption. This makes them particularly suitable for environments exposed to moisture.
Porcelain bathroom tiles offer several advantages:
- Durable surfaces for everyday use
- Low water absorption
- Easy maintenance
- A wide selection of colours, textures and sizes
- Excellent compatibility with underfloor heating when correctly installed
Unlike many types of natural stone, glazed porcelain tiles generally do not require special sealing.
Another major advantage is design flexibility. Modern manufacturing techniques can reproduce the appearance of limestone, marble, wood, concrete and travertine with impressive accuracy.
Nevertheless, a tile's technical suitability should always be checked. A glossy porcelain tile that looks excellent on a bathroom wall may not be appropriate for a wet shower floor.
Mistake 2: Underestimating Slip Resistance
One of the most important questions when choosing bathroom floor tiles is how much grip the surface provides.
A tile that feels perfectly safe when dry may behave differently when exposed to water or soap.
This is particularly important around bathtubs, in front of showers and inside walk-in shower areas.
R9, R10 and R11: Understanding slip-resistant bathroom tiles
Ceramic floor tiles are often classified according to their slip resistance.
Common classifications include R9, R10 and R11. These describe slip resistance under test conditions involving footwear.
R9 indicates a lower level of slip resistance within this classification, while R10 and R11 indicate progressively higher levels.
Many homeowners prefer matt porcelain bathroom floor tiles with a lightly textured surface. Some of these products have an R10 rating.
However, R classifications alone are not sufficient for choosing shower floor tiles.
Barefoot wet areas are assessed using additional classifications, commonly A, B and C. The appropriate requirements depend on the intended application.
Our advice: Do not automatically choose the roughest possible tile. Highly textured surfaces can be more difficult to clean.
Instead, look for a suitable balance between slip resistance, comfort and maintenance.
When designing a bathroom, the exact product specification is more important than the general appearance of the tile.
Mistake 3: Choosing the Wrong Tile Size for a Walk-in Shower
Walk-in showers are increasingly popular in modern bathrooms.
They create an open, spacious appearance and can provide convenient access without a raised shower tray.
However, installing ceramic tiles in a level-access shower requires careful planning.
The shower floor must have sufficient slope to direct water towards the drain. The size of the tiles influences how easily this slope can be achieved.
Can large-format tiles be installed in a shower?
Yes. Large porcelain tiles can be used in a walk-in shower if the drainage system and floor construction allow it.
A linear shower drain can often be combined with a single sloping surface. This makes it easier to install larger tiles.
A central point drain usually requires the floor to slope from several directions towards the outlet.
In these situations, smaller tiles are often easier to install.
The additional grout lines may also contribute to grip, depending on the material and installation.
A visually appealing solution is to use large porcelain tiles throughout the bathroom and matching mosaics on the shower floor.
This creates a consistent design while accommodating the technical requirements.
Bathroom tiles are not waterproofing
Porcelain tiles have very low water absorption, but the tiled surface alone does not create a waterproof shower.
Grout joints, corners and pipe penetrations must all be properly protected.
A suitable waterproofing system must therefore be installed beneath the tiles.
For walk-in showers, this work should be carried out by a qualified professional.
Mistake 4: Assuming Large Tiles Are Unsuitable for Small Bathrooms
One of the most persistent myths in bathroom design is that small bathrooms require small tiles.
In reality, large-format bathroom tiles can make a compact space appear more spacious.
Small tiles create numerous grout lines that divide the visible surface.
Larger tiles produce a calmer, more continuous appearance.
Which tile size is best for a small bathroom?
30 × 60 cm: A versatile format for compact bathrooms, guest toilets and traditional wall installations.
60 × 60 cm: A popular choice for bathroom floors, offering balanced proportions and flexible installation.
60 × 120 cm: Particularly attractive for modern bathrooms. Installed vertically, these tiles can emphasise ceiling height. Horizontally, they create broad, elegant surfaces.
120 × 120 cm: Ideal for creating a minimalist appearance with fewer visible joints, provided the room layout allows an efficient installation.
For even larger surfaces, explore our large-format porcelain tiles, including slabs up to 160 × 320 cm.
Nevertheless, choosing the largest possible tile is not always the best solution.
In narrow bathrooms, an unsuitable format may result in excessive cutting and material waste.
Careful planning of tile placement and joints is therefore essential.
Are large bathroom tiles easier to clean?
Large tiles generally mean fewer grout lines, which can make everyday maintenance easier.
Porcelain surfaces are usually straightforward to clean, while grout joints may require additional attention.
Large-format porcelain tiles can therefore be a practical choice for homeowners who prefer a low-maintenance bathroom.
However, ceramic tiles should never be installed completely without joints. Even rectified tiles require properly designed grout and movement joints.
Mistake 5: Failing to Coordinate Floor and Wall Tiles
A bathroom can contain several beautiful materials and still look unbalanced.
This often happens when floor tiles, wall tiles, bathroom furniture and fittings are selected independently.
The most successful bathroom interiors usually follow a consistent design concept.
Using the same porcelain tiles on floors and walls
One increasingly popular approach is to use the same tile collection on both the floor and walls.
Many Italian manufacturers offer matching formats and finishes within a single series.
For example, a natural stone-look tile can be installed on the bathroom floor, while a larger version of the same design continues across the walls.
This creates a calm, architectural appearance.
The floor finish must, of course, be suitable for walking and the intended moisture conditions.
Creating feature walls with decorative tiles
Not every bathroom needs dramatic colours on every wall.
A single feature wall behind a washbasin, bathtub or shower can provide enough contrast.
Small glossy wall tiles are especially effective because they reflect light and add depth to the room.
Combining expressive wall tiles with neutral porcelain floor tiles can create an elegant contrast without overwhelming the space.
Mistake 6: Underestimating the Importance of Tile Colour
The colour of your bathroom tiles can dramatically affect how large, bright and welcoming the room feels.
Natural daylight, artificial lighting, furniture and fittings all influence the result.
Beige bathroom tiles for a warm, natural interior
Beige, sand and cream tones are particularly popular in contemporary bathrooms.
They work beautifully with wooden furniture, bronze fittings and natural materials.
Travertine has been used in architecture for centuries. Its natural texture and warm colours create a timeless atmosphere.
Modern porcelain reproductions provide the aesthetic character of travertine with easier everyday maintenance than many natural stone surfaces.
White and marble-look bathroom tiles
Light bathroom tiles reflect more light and can make small rooms feel more open.
White, ivory and warm cream are particularly effective in bathrooms with limited natural daylight.
For a more decorative appearance, marble-look porcelain tiles introduce elegant veining without requiring additional colours.
White marble effects with subtle grey or gold details are popular for sophisticated bathroom interiors.
Grey bathroom tiles
Grey porcelain tiles remain versatile, especially when combined with black fittings, oak furniture or white sanitary ware.
However, the undertone matters.
Cool greys may feel rather austere in bathrooms without windows, while warm grey and greige tones create a softer appearance.
Wood-look bathroom tiles
Wood-effect porcelain tiles bring warmth into bathrooms without the maintenance requirements of natural timber.
A particularly successful combination is a warm wood-effect floor paired with large beige wall tiles.
Mistake 7: Ordering Bathroom Tiles Without Seeing Samples
A tile may appear perfect on a computer screen but look different in your own bathroom.
Screen settings, daylight, artificial lighting and surrounding materials all affect colour perception.
A beige tile might look warmer under artificial light, while a matt stone texture may be more pronounced in reality than in a product photograph.
For this reason, we recommend comparing actual samples before placing a large order.
Visualise bathroom tiles in your own home
Simply take a photograph of your bathroom or upload an existing image.
You can then compare different porcelain tiles directly in your space and explore various colours, formats and designs.
This is particularly useful when deciding between 60 × 120 cm tiles, marble effects, travertine or minimalist stone surfaces.
Order tile samples before buying
VITALE TILES offers a large selection of samples. Many are available in their original size or as convenient sample pieces measuring approximately 15 × 25 cm.
Samples in stock are generally dispatched quickly by Swiss Post, with tracking information provided after shipment.
Customers can currently use the voucher code VT-Muster-2026 to order two free tile samples.
Place the samples in your bathroom and compare them in daylight and artificial lighting.
If possible, hold them next to your planned bathroom furniture, washbasin and fittings.
Bathroom Tile Trends for 2027
Modern bathroom design increasingly treats the bathroom as an extension of the living space.
Warm colours, natural materials, architectural surfaces and carefully selected decorative accents are important design directions for 2027.
Natural travertine and limestone effects
Warm beige and cream stone effects create a comfortable, timeless atmosphere.
An attractive example is the I Travertini collection by Italgraniti, which recreates natural travertine patterns in porcelain stoneware.
Italian manufacturers such as Marazzi and Florim also offer a wide selection of natural stone-inspired ceramic surfaces.
Large-format tiles with minimal grout lines
Formats such as 60 × 120 cm and 120 × 120 cm remain popular for contemporary bathroom interiors.
They create calm surfaces and allow furniture, mirrors and fittings to become the main visual elements.
Colourful decorative wall tiles
Alongside natural colours, turquoise, sage green, deep blue and earthy shades offer opportunities for more individual interiors.
Glossy small-format tiles are particularly effective in showers and behind washbasins.
Rather than covering every surface in a strong colour, consider using a single decorative area.
This approach creates character while maintaining a balanced design.
How Much Do Bathroom Tiles Cost in Switzerland?
The price of bathroom tiles depends on the manufacturer, format, surface, thickness and production method.
A simple porcelain floor tile may cost considerably less than a large-format porcelain slab with a complex natural stone design.
However, the price per square metre is only one part of the total bathroom renovation budget.
Installation, waterproofing, substrate preparation, cutting and additional materials must also be considered.
Are more expensive bathroom tiles worth it?
Consider a bathroom with 25 m² of tiled floors and walls.
At CHF 40 per m², the tile material costs CHF 1,000.
At CHF 60 per m², the material costs CHF 1,500.
The difference is CHF 500.
Over an assumed lifespan of 30 years, that corresponds to approximately CHF 16.70 per year, or CHF 1.40 per month.
This simplified example excludes installation, waste and additional materials, but it illustrates why choosing a tile you genuinely like can be worthwhile.
One practical way to control costs is to combine a premium feature tile with more affordable neutral floor and wall tiles.
