I'm in the process of doing up a room in my home for short term rental. It is a small room, and approximately square; about 12.5 ft by 12.5 ft. This room is on the edge of a building; we normally refer to it as a tower room. A picture of the exterior appears below; it is the room below the dome closer to the viewer. The room no longer looks exactly as it did in this photo; the wooden windows have been removed and will be replaced by sliding windows. I was advised that tiles on the floor and the walls was a good way to go, because they were durable and low-maintenance. I'm in Bombay, India.
The types of tiles available includes ceramic, vitrified, porcelain, and stone. This article has a more comprehensive list, but my list covers most of the types commonly used, I think; the others in the article seem more exotic.
So, the question is, which tiles do I use and where? I am quite partial to granite, so I'm thinking granite tiles would be nice. But I'm not sure what the pros and cons of this are. Also, I'm hoping to stay in the ₹ 50-100 range.
One thing to be aware of it that there are very heavy seasonal rains in this part of the world, usually from June through September. Therefore moisture can seep through the walls from outside. However, it should not be an issue for the floor.
So, my question is - which type of tiles do I choose? What are the pros and cons? An important criteria is durability. Another is aesthetics. People will be sleeping in this room. It will be hot outside much of the time. There will be an A/C running inside. Are any of these factors relevant?
