It depends on the overall theme of your house and if there are any special requirements for either marble or wood. Wood is softer to tread on than Marble and Marble is easier to clean.

I want to get laminated wooden flooring done in my house, please suggest me about brand, costing, usability, etc.

Hello there, When you consider laminate wood flooring (AC5) be sure to choose the right brands for color fastness and uniform bevels . Usually Squarefoot and Pergo are being stocked by local dealers. As far wooden floorings are concerned, it is best to avoid in hot and humid zones . You could also consider wooden textured tiles for a similar look. On the brighter side, they impart an elegant look and is quite easy to clean and resist daily wear and tear. However, heavy things could scratch the floor when moving around like a sofa or fridge.

Anand, It depends on your budget and taste. If it's just one room you can opt for either living or master bedroom.
