How to choose tiles for a small bathroom - expert guide

Added: Friday, 12/5/2025


Choosing the right tiles for a small bathroom is a crucial decision that affects both the functionality and visual perception of the space. From our many years of experience in the installation industry, we know that properly selected tiles for a small bathroom can visually enlarge the interior and create a harmonious arrangement.

At Onninen, we observe that the most common mistakes when choosing tiles stem from a lack of knowledge about the basic principles of visually enlarging spaces and the properties of various ceramic materials. As a market leader in the installation sector, we want to share practical tips that will help avoid costly mistakes.

In Onninen's assortment, you will find comprehensive solutions - from ceramic tiles to high-quality gres, as well as complete bathroom equipment all in one place.

Tile Size - The Key to Visually Enlarging Space

Contrary to popular belief, large tiles in a small bathroom are a brilliant visual trick. Large-format tiles minimize the number of joints, creating the impression of a uniform, spacious surface. In practical installation, we recommend formats of at least 60x60 cm or rectangular tiles from 30x90 cm to 60x120 cm.

Tile Formats for Small Bathrooms

Tile Format Recommended Use  Optical Effect
60x60 cm   Floors and walls  Enlargement of space
30x90 cm Walls Optical elongation
60x120 cm Main surfaces Maximum enlargement
Mosaic (up to 5x5 cm) Decorative accents Focal point

Tile Laying - Direction Matters

The way rectangular tiles are laid significantly affects the perception of space. Horizontal laying visually widens the bathroom, while vertical laying optically raises the room. In our practice, we most often recommend vertical laying in small bathrooms with low ceilings.

Tile Color - Light Colors are Essential

Light tile colors are the foundation of a successful arrangement in a small bathroom. White ceramic tiles reflect light perfectly and visually enlarge the space. In Onninen's offer, you will find a wide range of tiles in shades of:

  • Classic white - a timeless solution that maximally brightens the interior
  • Cream shades - a warm alternative to white, adding coziness
  • Light beiges and grays - modern solutions with a subtle character
  • Pastels - delicate color accents without overwhelming the space

Glossy or Matte Tiles for a Small Bathroom?

Glossy finish tiles are ideal for the walls of small bathrooms - they reflect light like a mirror, additionally visually enlarging the interior. However, for the floor, we recommend matte or slightly textured tiles for safety reasons - they provide better slip resistance.

Gres or Ceramic Tiles - Differences You Need to Know

In Onninen's assortment, we offer both gres tiles and traditional ceramic tiles. Knowing the differences between them will help you make an informed decision.

Technical Properties - Deciding Parameters

Property Gres Ceramic Tiles
Absorbency Below 0.5% About 3-10%
Hardness (Mohs scale) 8-9 5-6
Frost Resistance Yes Limited
Wear Resistance Very high Average
Thickness 9-12 mm 6-10 mm

From our experience, gres is a better solution for small bathrooms that are used intensively. Low absorbency and high resistance to damage ensure long-lasting aesthetics of the surface. Ceramic tiles work well as a budget option, offering a wider selection of decorative patterns.

Practical Installation Tips

Grout - A Detail That Makes a Difference

In small bathrooms, we recommend narrow grouts (2-3 mm) in a color similar to the tiles. Contrasting grouts visually "cut" the space, reducing it visually. Modern adhesive-free systems allow for practically invisible joints.

Wet Zones - Additional Requirements

Areas exposed to direct contact with water require special attention. We recommend tiles with a slip resistance class of at least R10, and in the shower area even R11. In our offer, you will find tiles that meet the highest safety standards.

  • Floor in the shower cabin - R11-R12 slip-resistant tiles
  • Wet walls - tiles with absorbency below 3%
  • Dry areas - decorative tiles with higher absorbency can be used

Trends in Small Bathrooms - Proven Solutions

As experts in the installation industry, we observe a growing interest in wood-like tiles in small bathrooms. Gres that imitates wood combines natural aesthetics with the practicality of ceramics - it is waterproof, easy to clean, and does not require impregnation.NORTHWOOD BEIGE floor tile 198x1198x8mm, structure, wood-inspired, matte, rectified, class I, wear resistance class: PEI4, slip resistance class: R10b, [pack=1.19m2=5 pcs.] NT1053-002-1

Popular Patterns and Textures

  • Single-color tiles - a timeless base for bathroom accessories
  • Subtle structures - delicate reliefs adding depth to the surface

In Onninen's assortment, you will find tiles from renowned manufacturers that guarantee high quality of workmanship and durability of colors for years of use.

Frequently Asked Questions

1. What tiles best enlarge a small bathroom?

Light large-format tiles measuring 60x60 cm or larger are the best choice. They minimize the number of joints, and light colors reflect light, visually enlarging the space. We also recommend glossy tiles on the walls.

2. Can different types of tiles be combined in a small bathroom?

Yes, but in moderation. It is best to combine a maximum of two types of tiles - e.g., uniform tiles on most surfaces and mosaic as a decorative accent in the shower area or behind the sink.

3. Gres or ceramics - which works better in a small bathroom?

Gres is a better choice due to its low absorbency (below 0.5%) and high resistance to damage. In small bathrooms that are used intensively, it provides greater durability and ease of cleaning.

4. What grout colors should be chosen for a small bathroom?

Grouts in a color similar to the tiles are the best solution. Contrasting grouts visually divide the surface, reducing the sense of spaciousness. Choose narrow grouts of 2-3 mm for a better visual effect.

5. Can dark tiles be used in a small bathroom?

Dark tiles can be used as an accent, but not on the main surfaces. It is best to use them as a decorative strip or on one accent wall, keeping light colors on the remaining surfaces.

6. How many tiles should be bought for a small bathroom with a reserve?

Always buy 10-15% more tiles than calculated for the surface area. A reserve is necessary for waste during cutting and potential future repairs. Tiles from the same production batch may not be available later.

7. Are structural tiles suitable for small bathrooms?

Structural tiles can be used pointwise as a decorative accent. For main surfaces, smooth tiles are better, as they are easier to keep clean and do not visually overwhelm the small space.
