Porcelanosa Karachi Grey 120x120cm

Yes, the Karachi Grey 120x120cm is rated for both floor and wall use in bathrooms, and its technical porcelain construction makes it highly durable and resistant to moisture. The large 120x120cm format creates a stunning, uninterrupted look across bathroom floors, reducing the number of grout lines for a cleaner finish. If you are using it in a wet room or shower area, we recommend checking with your installer about appropriate anti-slip treatments or grout sealants.

Yes, this tile is compatible with underfloor heating systems, and its versatile room rating includes living rooms, bedrooms, hallways, kitchens, and bathrooms, making it one of the most flexible options in the Karachi range. Porcelain is an excellent conductor of heat, so it works efficiently with both electric and water-fed underfloor heating systems. Always follow your underfloor heating manufacturer’s guidelines for adhesive and grout selection when installing large-format tiles.

Each box contains 1 tile covering 1.44 square metres, so for a large hallway you will need to order one box per 1.44m² of floor area. For example, a 10 square metre hallway would require approximately 7 boxes as a minimum, but we strongly recommend adding at least 10% extra for cuts, especially around doorways and edges where large-format tiles like this 120x120cm size require more precise trimming. The rectified edges help keep grout lines tight and consistent, which is particularly important in a long hallway where visual alignment is very noticeable.
