In what country are you building this house? 9 foot or vaulted ceilings are taller than the US builder average of only 8 feet (this is the distance from the ground to the ceiling). If you have a small room, having a higher ceiling (even only 1 foot extra) will make the room feel more open and airy. In a small house of 1500 square feet, having high ceilings would go a long way in making it feel much larger than it really is. It is especially beneficial in a hot climate because heat rises so you will spend less on cooling costs. It is not so beneficial in a cold climate. It still looks nice, though!

Thanks a lot for your comment. I wouldn't exactly call it a walk in-closet. As you can see from the drawing, Its space provided for two single wardrobe (one on each side). Maximum width can be around 3.5 ft. The humidity point is quite relevant. The question is would it be possible to include a wet room in the space i.e. 6ft x 8.6ft. - considering I don't remove the dress wall. Wanted to get a sense on the possible layout. Thanks and look forward to your advise.

I have sensitive feet (can't stand to walk on stones or concrete or grass or sand, etc) so a pebble shower floor would be HELL....but that's me. You need to know if you can handle/will be happy with a pebble floor. And some of the worst installs on Houzz have involved pebble floors in showers...and they are very tough to keep the grout clean. And the real stone versions still need to be sealed. Just like "stone" floors. The choice is yours. But first...bare foot on pebbles to find out if you like it underfoot.

Hi, I think full wooden tiles will feel like pathetic. Try disparate like combinations of glossy and wood tiles or like 2 walls and floor with wood tiles and other 2 walls light colored glossy tiles to break the monotony.Thank u.
