97x97mm tiles are a small-format square tile — commonly called mosaic tiles — that suit bathroom floors, wet area walls, shower recesses, and kitchen splashbacks where a fine grid pattern and strong slip resistance are priorities. This collection covers ceramic, porcelain, stone, marble, and glass options in the 97x97mm format, available in a range of colours and finishes.
What are 97x97mm tiles used for?
97x97mm tiles are most commonly used on bathroom floors, shower floors, and splashbacks. The small format creates a high grout-line density, which increases surface friction and makes these tiles well suited to wet areas where slip resistance is a practical requirement. They also work on feature walls and around vanities where a detailed grid texture is the goal.
Beyond bathrooms, the format is used on kitchen splashbacks and laundry walls. The sheet-mounted format means installation covers area quickly despite the small individual tile size.
What materials are available in 97x97mm tiles?
The main material categories are ceramic, porcelain, natural stone (marble, travertine, slate), and glass. Ceramic and porcelain are the most practical for wet areas: they are non-porous, easy to clean, and dimensionally stable. Natural stone adds texture and variation but requires sealing. Glass tiles reflect light and suit splashback applications but are not recommended for floor use due to slip risk.
Porcelain in this format typically carries a PEI rating of 3 or 4, suitable for residential floors and walls. Check the product data sheet for the specific PEI rating and slip-resistance classification (P-rating) before specifying for a floor.
What finishes and colours come in 97x97mm?
White and off-white are the highest-demand colours, followed by black, charcoal, and greige tones. Colour-specific searches for green, blue, and black-and-white mosaic tiles are also consistent in AU, reflecting their use in feature applications. Finish options typically include matte (most common for floors due to slip resistance), gloss (walls and splashbacks), and textured or tumbled finishes on natural stone.
Matte white remains the most versatile option for bathroom floors because it reads as neutral against any tapware finish and is straightforward to match when replacing tiles later. Browse the full tiles collection to compare across formats and colours.
How do 97x97mm tiles compare to other mosaic formats?
The 97x97mm format sits between the standard 100x100mm mosaic and smaller penny-round or hexagon formats. At 97mm, grout joints on a standard 3mm joint setting produce a very similar look to 100mm mosaics but with slightly more grout coverage visible. Penny round and hexagon formats (typically 48mm or 50mm across) produce a finer, busier pattern and require more grout, which increases maintenance. Finger or strip mosaics (around 23x73mm or 48x98mm) give a linear, elongated look that reads differently on large surfaces.
For a bathroom floor where the tile needs to recede visually rather than compete with other surfaces, the 97x97mm square is a reliable choice. Its scale is readable from standing height without overwhelming a small room.
What grout and substrate preparation do 97x97mm tiles need?
Small-format mosaic tiles are typically supplied on mesh-backed sheets — usually 300x300mm or 305x305mm sheets — which means the setting bed needs to be flat to within 3mm over 1800mm, or individual tiles will rock and crack after grouting. Use a flexible tile adhesive rated for the substrate type (cement sheet, waterproofed FC sheet, or rendered masonry). For wet areas, the substrate must be waterproofed to AS 3740 before tiling commences.
Grout joint width for 97x97mm sheet-mounted tiles is determined by the sheet spacing, typically 2-3mm. An unsanded grout suits joints under 3mm; sanded or epoxy grout suits wider joints or high-traffic floors. Epoxy grout is the most stain-resistant option for shower floors but requires more careful application.
How do I calculate how many 97x97mm tiles I need?
Measure the area in square metres, then add 10% for cuts and waste on a standard rectangular room, or 15% if the layout runs on a diagonal. Because 97x97mm tiles are sold on sheets rather than individually, confirm the sheet coverage figure from the product listing. Divide total area (including waste allowance) by sheet coverage to get your sheet count, then round up to the nearest full box.
For a 1.5m x 1.5m shower floor (2.25m2), a 10% waste allowance gives 2.48m2 — check the box coverage to confirm how many boxes that requires. If you are matching an existing installation, buy all tiles from the same production lot (batch number) to avoid shade variation.
Which brands stock 97x97mm tiles at The Blue Space?

Frequently Asked Questions
What is a 97x97mm tile?
A 97x97mm tile is a small-format square tile, part of the mosaic tile category. At just under 100mm per side, tiles in this size are most commonly supplied on mesh-backed sheets and used on bathroom floors, shower recesses, and splashbacks where slip resistance and fine grout-line texture are required.
Are 97x97mm tiles suitable for bathroom floors?
Yes. 97x97mm tiles are well suited to bathroom floors. The high grout-line density from the small format increases surface friction, and porcelain options in this size typically carry a P4 or P5 slip-resistance rating, which meets Australian standards for wet area floors in residential bathrooms.
What is the difference between 97x97mm tiles and mosaic tiles?
97x97mm is a specific size within the broader mosaic tile category. Mosaic tiles generally range from around 20mm to 100mm in the smallest dimension and include formats such as penny round, hexagon, finger strip, and square. The 97x97mm square format is one of the most common mosaic sizes stocked in Australia.
How much grout do I need for 97x97mm tiles?
Grout consumption for 97x97mm sheet-mounted tiles depends on joint width (typically 2-3mm) and tile thickness (usually 6-8mm). As a rough guide, expect to use around 0.5 to 0.8kg of grout per square metre at a 3mm joint. Always check the grout manufacturer's coverage table for the specific joint size and tile thickness.
Can 97x97mm tiles be used on a shower floor?
Yes, provided the tile carries an appropriate slip-resistance rating. For a domestic shower floor, a minimum P4 rating is required under AS 4586. Porcelain and textured ceramic 97x97mm tiles often meet this threshold. Glass mosaic tiles in this size are not recommended for shower floors due to insufficient slip resistance when wet.
