“Porcelain that behaves like stone and cleans like tile. Underfloor heating’s best friend.”

Onyx Effect tiles in porcelain: the two Taj Mahal tiles, Cappuccino and Pearl, polished. 10 mm thick at 600 mm by 1200 mm, following a banded stone; made in Spain, frost resistant, specified for floor and wall.
Still unsure? Real people, honest advice.
Onyx is a stone that reads in bands rather than veins, and the two Taj Mahal tiles follow it in polished porcelain. Both are 600 mm by 1200 mm and 10 mm thick, made in Spain, frost resistant, listed as compatible with underfloor heating, with a water absorption ratio listed under 0.50, specified for floor and wall, two to a box covering 1.44 square metres. Pearl is the pale version; Cappuccino the warm one. Both also sit in the marble-effect subcategory.
The reason to choose the porcelain over the stone is the same as for marble, only more so: real onyx is soft and porous, and it is a wall material in most buildings for that reason. The porcelain keeps the look and drops the fragility. It does not etch under household acids, takes on almost no water, and it is consistent from tile to tile.
It is a decorative tile, and that decides where it goes. A shower enclosure, a bathroom wall, a feature wall behind a basin, a hallway floor that stays dry: rooms where the surface is meant to be looked at. A whole room of banded polished stone can be a lot, and many schemes use it on one wall against a matt floor. On a floor that gets wet, a polished porcelain is slippery, and the HSE pendulum scale for slip resistance is quoted below; the figure for these tiles is on the manufacturer's data sheet.
Laid by a tiler on a flat subfloor, in adhesive, grouted and sealed at the edges. The screed regularity classes and the surface temperature limits for a tiled floor over heating are quoted below. For the same tone at a softer sheen, the lappato stone effects; for the marble look in matt, Luna Blanca and Night Lux in the marble subcategory.
