Pankaj, I just realized that initially you told us that the bathroom area was 12'-0" x 9'-0" and later you mentioned that it was 11'-8" x 8'-0". In the last floor plan, I forgot to change the bathroom with the new dimensions. Below is the floor plan with the correct dimensions for the bathroom. The bedroom is ok, I drew it 19'-2" x 12'-6". The new layout does not change the way things are placed. Everything still fit. The only difference is that the vanity is now 4'-4" long instead of 4'-8". and the toilet is closer to the shower by 1'-0". Can you give me the lengths of the walls K and L. They are the walls between the vanity and the shower area. I will send you the new layout once you give me the length of these 2 walls.

OK... but the wire wont be lower as it is fixed now. The wire in the pics below is the wall facing each other. They were leveled on equal height but the beam on one wall makes it seem a little above. But i think you guys are absolutely right that up and down lights wont look good there. I think you are right about down lights lessismoore. Would it look good if i go with two different lights on opposite walls??? it would look odd right.

there is no perfect dimensions for an island. Try to organce space subdividing into smaller cabinets of 60x60 cms which is the max space for a structural division and works for seating area as well

There is no average height for the table and chairs.There're height standards for all the furniture. The standard height for the table is 30" and for the chair, it is 18". The depth of the table should be atleast 36". It might be a little broad say 42" but not more. The length if the table is defined with the seats required. The chair seat size should be 16" with the back height be 30" atleast. It might be more depending upon the design of the table.
