All three make great flooring surfaces. Marble is a softer stone than granite. There are various ceramic tile glazes with differing degrees of harnesses. If the durability is an issue, make sure you purchase one that has a high 'hardness' rating. Natural stones usually require periodic sealing and polishing. The same can be true of ceramic tiles. Be careful what cleaners one uses on these floors as some harsh cleaners can damage the surface.

Probably the same material as the kitchen and rest of the main floor.

Hello Rahul, limiting to your query on granite - It is quite a beautiful, natural and hard material. For applications in kitchen, store and balcony they would do good. There are some points you should consider for granite application - - Granite usually occur in dark shades so consider the lighting in the area of application. - Ask the vendor for iron content in any natural stone for avoiding rust marks. - The process of application and polishing is cumbersome but thank god in India, craftsmen are easily available. - Do not go for a elaborate gloss polish to avoid skidding/slippery floors. - It is also advisable to re-polish/reseal them every 3-5 years. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore.
