Marble

Marble is a polished stone flooring surface of pure white veined with subtle grey, the most luxurious ground cover available in the outdoor catalogue. Crafted from Stone and Sea Glass Fragments, it contributes the highest single-tile Flooring sub-score boost of any outdoor surface and simultaneously adds to the Elegance sub-score, making it the top choice for Resort, Chic, or formal garden environments where the floor is as important as everything above it. Its reflective surface picks up ambient light differently at different times of day, giving Marble-floored areas a subtly dynamic visual quality.

Psychic-type Pokémon respond more strongly to Marble than to any other flooring material — the combination of visual purity and high Elegance score creates an environment that species like Gardevoir, Gothitelle, and Espeon find genuinely appealing rather than merely tolerable. Marble pairs naturally with Arched Tiling as a border treatment, and with Resort or Chic furniture lines above. Its Sea Glass crafting requirement means it becomes available around the mid-game point when coastal biomes begin yielding materials consistently — timing its introduction with a corresponding upgrade of surrounding furniture creates a dramatic visual step-change in overall habitat quality.
