How to Style Gemstone Onyx White Tiles
The white polished surface of the Gemstone Onyx acts as a blank canvas that elevates everything around it. In a master bathroom, pair with a freestanding stone bath, wall-hung sanitaryware and brushed nickel or rose gold fixtures — the veining in the tile does all the decorative work so the room needs very little else. For a contemporary kitchen, run these tiles as a full-height splashback or across the floor under dark cabinetry; the polished surface reflects the cabinetry colour beautifully, adding depth to the space. Use slim grey grout lines at 1.5–2mm to maintain the seamless stone effect. For hallways, lay in a straight brick-bond pattern along the length of the space to draw the eye and make the room feel longer.
How Much Do I Need?
At 60x120cm, each tile covers 0.72m², so you need approximately 1.39 tiles per square metre. Always add 10% for cuts and wastage. For a 10m² bathroom floor you would need approximately 16 tiles. Our team can provide a free estimate — email sales@tilesparadiseuk.com with your room dimensions.

Frequently Asked Questions
What is the difference between polished and gloss porcelain tiles?
Both finishes are highly reflective, but they achieve this differently. A gloss tile has a glazed coating applied on top of the tile body, giving a bright, uniform shine. A polished tile is mechanically ground and buffed after firing, which refines the surface to a mirror-like finish that more closely resembles natural polished stone. Polished tiles tend to have a slightly softer, more luxurious sheen compared to the harder brilliance of gloss tiles — making them ideal for achieving a natural marble or onyx look.
Are 60x120cm tiles difficult to install?
Large format tiles like 60x120cm require more care during installation than smaller tiles. The substrate must be perfectly flat — any unevenness becomes more visible over a larger surface. A professional tiler should use a large-format tile adhesive (C2TE rated) with full-bed coverage to prevent hollow spots. Due to their size and weight, 60x120cm tiles are generally best fitted by an experienced tiler rather than as a DIY project.
Are polished porcelain tiles slippery on floors?
Polished porcelain tiles have an R9 slip rating, which is suitable for domestic floor use in dry areas such as hallways, living rooms and bedrooms. In wet areas such as bathrooms and wet rooms, extra caution is recommended — use a bath mat near the shower and ensure the floor is dried regularly. For commercial applications or wet room floors, we recommend choosing a tile with an R10 or R11 rating for greater slip resistance.
Do white tiles with veining look like real marble?
Modern digital printing technology means that high-quality porcelain tiles like the Gemstone Onyx White can replicate the look of natural marble and onyx very convincingly. The key advantage over real marble is that porcelain is significantly more durable, does not require sealing, is resistant to staining and acid damage, and costs considerably less. Each tile face features unique veining variation, so when laid, the overall effect closely resembles a naturally veined stone floor or wall.
How do I clean polished white porcelain tiles?
Polished white tiles are straightforward to keep clean. For regular maintenance, mop with warm water and a pH-neutral tile cleaner — avoid acidic or bleach-based products as these can dull the polished surface over time. For stubborn marks, a dedicated porcelain tile cleaner applied with a soft cloth works well. Dry the surface after mopping to prevent water marks, which are more visible on polished finishes. Avoid abrasive cleaning pads which can scratch the polished surface.
Can I order a sample before buying?
Yes — we strongly recommend ordering a sample before committing to a full order, particularly for large format tiles where colour and veining variation is more prominent. Samples allow you to see the true colour in your own lighting conditions and against your existing fixtures.

- Check where it can go. Floors need a tile rated for floors. In showers and wet rooms, a matt or anti-slip finish is safer underfoot than polished.
- Measure and add 10%. Length x width for each area, added together, plus 10% for cuts and breakage (15% for herringbone or diagonal layouts). The calculator above does this for you.
- Pick your joint. This tile is rectified (precision-cut edges), so a slim 2mm joint gives a near-seamless look. Large tiles need a flat surface; levelling clips help.
- Order it all together. Tiles are made in batches that can vary slightly in shade, so buy the full amount in one order.
- See it first. Order a sample to check the colour and finish in your own light.
