Wall Tiles Explained: Beyond Bathroom Basics

Tiles Have a Reputation Problem

In Dutch homes, tiles are associated with bathrooms and kitchen splashbacks — practical surfaces in wet rooms. This association has limited tiles to functional roles, hiding one of the most versatile and beautiful wall finish materials available.

Tiles can create walls with pattern, texture, colour, and material character that rival any plaster or paint. From the handmade irregularity of Moroccan zellige to the sleek precision of large-format porcelain, the tile family offers options for virtually every aesthetic and functional requirement.

Tile Types for Walls

Zellige Tiles

Handmade Moroccan tiles with a distinctive glazed surface that shows natural variation — slight undulations, colour differences, glaze pooling, and imperfect edges. Each tile is individually shaped and glazed, creating walls with extraordinary visual richness and handmade character.

Zellige tiles catch and reflect light from their undulating surfaces, creating a dynamic, shimmering quality that changes with the light. In white or pale tones, zellige creates a classic, timeless aesthetic. In rich colours (deep blue, emerald green, terracotta), it creates dramatic feature walls.

Best for: Kitchen splashbacks, bathroom walls, fireplace surrounds, feature walls. Mediterranean, artisan, and eclectic interiors.

Subway Tiles

The classic rectangular tile (typically 7.5 x 15 cm or 10 x 20 cm) laid in a brick-bond pattern. Subway tiles originated in the New York subway system and have become one of the most enduring tile formats in residential design.

Their appeal lies in simplicity and versatility. Subway tiles work in almost any context — traditional, contemporary, industrial, Scandinavian. Variations in size, colour, finish (glossy, matte, crackle glaze), and grout colour create dramatically different effects from the same basic format.

Best for: Kitchen splashbacks, bathroom walls, utility rooms. Almost any interior style depending on colour and finish choice.

Large-Format Porcelain

Tiles of 60 x 60 cm or larger — some reaching 120 x 240 cm — that create wall surfaces with minimal grout lines. Large-format porcelain can convincingly replicate the appearance of marble, concrete, stone, and even wood, creating uniform surfaces that are practical and visually impressive.

The near-elimination of grout lines gives large-format tiles a sleek, seamless quality. In bathrooms and showers, this means fewer joints where moisture and mould can accumulate.

Best for: Bathrooms, shower walls, kitchen splashbacks, feature walls in contemporary interiors.

Handmade and Artisan Tiles

Beyond zellige, a wide range of handmade tiles offer unique surface qualities: terracotta tiles with natural colour variation, encaustic cement tiles with geometric patterns, hand-painted ceramic tiles with individual artistry, and slip-cast tiles with organic shapes.

Handmade tiles add a human quality that machine-made tiles cannot match. The irregularities — slight size differences, colour variation, surface texture — create walls with visible craft and character.

Best for: Feature walls, fireplace surrounds, kitchen splashbacks, powder rooms. Traditional, Mediterranean, and eclectic interiors.

Natural Stone Tiles

Marble, travertine, limestone, and slate tiles bring geological beauty to walls. Each tile is unique — the veining, colour variation, and fossil content are unrepeatable natural features. Natural stone on walls creates a material presence that ceramic tiles cannot fully replicate.

Best for: Bathroom feature walls, fireplace surrounds, entrance halls, luxury interiors.

Glass Tiles and Mosaics

Glass tiles reflect and refract light, creating luminous wall surfaces. Mosaic formats (small tiles in sheets) allow intricate patterns and gradients. Glass tiles are completely waterproof and stain-resistant, making them ideal for wet areas.

Best for: Shower walls, kitchen splashbacks, decorative accents, pools and spa areas.

Tiles Beyond Wet Rooms

While tiles are essential in bathrooms and kitchens, their potential extends much further:

Living room feature walls: A handmade tile feature wall — zellige, encaustic, or artisan ceramic — creates a focal point with texture, colour, and craft character. Tiles on a fireplace wall or chimney breast add material richness that plaster alone cannot achieve.

Entrance halls: Durable, easy to clean, and visually impactful. Decorative tiles in an entrance hall create an immediate impression and withstand the heavy traffic that entrance walls endure.

Dining rooms: A tiled accent wall behind a sideboard or dining area adds colour and pattern that enhances the room's atmosphere, particularly effective with hand-painted or patterned tiles.

Grout: The Invisible Design Decision

Grout colour and width dramatically affect the appearance of tiled walls:

Matching grout (same colour as the tile) minimises the visibility of grout lines, creating a more unified surface. This approach emphasises the tile surface rather than the pattern of the joints.

Contrasting grout (darker or lighter than the tile) emphasises the grid pattern and individual tile format. White tiles with dark grout create a graphic, industrial quality. Dark tiles with light grout create a defined, structured pattern.

Minimal grout lines (1-2 mm) create a sleek, continuous appearance. Wider grout lines (3-5 mm) create a more traditional, handcrafted character.

Epoxy grout is waterproof and stain-resistant — essential for shower walls and areas that need hygienic cleanability. Standard cement grout is more porous and can stain or discolour over time.

Laying Patterns

The same tile in different laying patterns creates entirely different wall characters:

• Brick bond (offset): The classic running bond pattern. Relaxed, versatile, and the most common layout for subway tiles.
• Stack bond (grid): Tiles aligned in a regular grid. Clean, modern, and slightly more formal than brick bond.
• Herringbone: Tiles laid at 45-degree angles in a V-pattern. Dynamic and visually engaging. Creates a sense of movement on the wall.
• Chevron: Similar to herringbone but with angled tile ends, creating a cleaner V-pattern. More contemporary than herringbone.
• Vertical stack: Subway tiles laid vertically rather than horizontally. Creates a modern, unexpected twist on the classic format.
• Fish scale: Curved tiles arranged in overlapping rows. Creates a distinctive, organic pattern popular in feature walls and splashbacks.

Practical Considerations

Weight: Tiles add weight to walls. Standard plasterboard walls can support lightweight tiles (ceramic, thin porcelain) but may need reinforcement for heavy materials (natural stone, thick porcelain). Verify wall capacity before specifying heavy tiles.

Substrate preparation: Tiles need a flat, stable, properly prepared substrate. Uneven walls lead to uneven tile surfaces. Waterproof membranes are essential behind tiles in wet areas — the tiles and grout alone are not fully waterproof.

Maintenance: Glazed tiles require minimal maintenance — a wipe with a damp cloth. Unglazed and natural stone tiles may need sealing. Grout maintenance is the primary ongoing task — keeping grout clean and intact prevents moisture problems.

Removal: Tile removal is disruptive and often damages the substrate beneath. Choose tiles you plan to keep for the long term, as replacing them is a significant project.

Making Tiles Work for You

The key to beautiful tiled walls is intentionality. Tiles chosen as an afterthought — the first subway tile that came to hand, in whatever colour was available — create walls that feel generic. Tiles chosen with care — the right format, the right surface quality, the right grout, the right pattern — create walls with genuine character and craft.

Do not be limited by the assumption that tiles belong only in bathrooms and kitchens. Wherever you want durability, pattern, colour, or material richness on a wall, tiles deserve consideration. They have been adorning walls for thousands of years, and the range available today is broader, more beautiful, and more accessible than at any point in history.
