Eventually when you come to resell, a pool is an added plus. But for your own purposes, emptying the pool and adding a deck over it with a hinged door and steps placed below would be great for storage (as per option b but bearing in mind you could revert). All the best for your lovely new home.

I have tumbled travertine (basically a form of marble) in the master bedroom and a marble mosaic in the master bath. It is higher maintenance. It stains and it wears differently in different areas. I am not doing natural stone in my new home. There are some fantastic tiles now that mimic all the stones, and a good quality porcelain tile will be very durable. Some ceramic wall tiles are "weaker" but I have had excellent luck with porcelain tile. Granite floors. Sure. But as people have said they also require maintenance like periodic sealing etc. In a house that size you don't want a different kind of floor in every room. I would stick to one or perhaps two types of floor tile in the main rooms. You can get away with additional types on walls in the bathrooms but I would keep the floors consistent. As far as cost goes, there is a very broad range of tiles and stones. In my shopping I have found some very good high quality floor tiles for reasonable prices. Stone has priced out higher...at least the ones I have looked at. Good luck!

I am assuming you haven't finalised your wall colours and colours of any other fixed elements. In case you have finalised your color scheme you would need to see which of these colours blend well or complement with that scheme. Assuming none of this info is available, then you could look at the neutrals which go with all colours. The white tile and the 2 colours at the end would be preferable. If you want color on the floor as well as drama, you can choose from the 2nd options from both sides or even the 1st from left.

Suvarchala, I am presuming that you do not want the doors to face each other due to privacy concerns. If that's right you wouldn't also want the guest/visitors to go to a bath in one of your rooms. Have you considered that before dropping off a common bath from the plan. If your neighbour has a door facing yours then you can also think about doing a mirror image of what respected member suggested above. I.e. door on the pooja room corner instead of the guest room corner. Thanks, Nitin CORNERSTONE DESIGNS Bangalore
