A slim architectural format
Often called finger, border or Kit Kat tiles, narrow pieces create a strong vertical or horizontal rhythm.
Kit Kat and finger tiles
Explore Kit Kat tiles, also known as finger tiles or border tiles, made in Japan for architectural interiors. Their slim proportions create rhythm and texture across bathroom walls, kitchen splashbacks, bars, counters and hospitality features. Kiln-formed glazes give each piece subtle differences in tone, depth and reflectivity.
Browse Japanese porcelain border formats in neutral, coloured, speckled and high-variation finishes. Order samples to compare colour, surface and grout before specification. Mittsu supplies locally stocked ranges from the UAE, UK and Europe, with additional colours and formats made to order in Japan. Contact the team for layout guidance, technical information, project quantities and lead times.
Often called finger, border or Kit Kat tiles, narrow pieces create a strong vertical or horizontal rhythm.
Kiln-formed glazes shift subtly in tone and reflectivity, giving the finished field more depth than a repeated print.
The format is used across bathrooms, kitchens, bars and hospitality features; suitability varies by product and installation.

Format and installation
Kit Kat tile is an informal name for a slim finger or border-format tile. Dimensions, mounting and surface vary between collections, so compare the product details rather than relying on the name alone.
Some formats may be mesh-mounted while others are supplied differently. Check the individual product page or sample before planning the setting-out and installation method.
A contrasting grout emphasises every joint and the narrow rhythm; a closer colour creates a quieter field. Test the combination with a sample before final selection.
Some small formats can accommodate gentle curves, but the tile dimensions, mounting, radius, substrate and installation method must be assessed for the specific project.
