You can use natural stone like marble for floor but do not use granite for floor at all as it is very slippery when wet. As for tiles do not go for glazed vitrified tiles for the floor for the same reason. ( floor becomes slippery once wet and may cause mishap) Go for ceramic anti skid tiles that are specially meant for bathroom floor. For wall tiles you can use whatever you like and then decide over the matching anti skid floor tile/ marble. Double charged vitrified tiles are usually used for flooring in rest of the house.

No, its not suggestive unless and until your get the seepage repaired. If its not repaired and tiled then the seepage will get diverted to some other wall .

Hello , I just checked dealers for Simpolo and it has names I already visited. still if you have any design number for Simpolo or Sunheart it can help. Thanks for your response

Teal is a very trendy colour, but having it on all four walls may be an overkill in the kitchen, especially with that dramatic chevron dado tile. I hope at least the 4th wall is white! The cabinets have to be white too
