This was in a condo kitchen. The orginal tile was still securly fastened to the concrete floor and was perfectly flat. Using a thin set that is made for adhering to any surface, the new tile was cemented directly to the old and it turned out great. A oak reducer was used to connect the tile with the existing hardwood floor hidden under the cardboard.
Here is the finished floor. the ceramic tiles are 24 x 18.
Since a floor with such large tiles has to be properly stablized, it increases the height and a good smooth transition to the ajoining floor in this case hardwood is a oak reducer. I've left a cut from the raw wood infront. The installed reducer is stained to match the existing oak floor.
After plywood is installed the floor had to be leveled with polymere thinset.
This is a 9 x 18 porcelain tile set in a brick pattern in the front hall of a house under full renovation. You can see some exposed subfloor. The floor boards were first screwed down wire mesh was then stapled down and instead of regular

Inexpensive 18 x 18 tiles were used here. The inserts are simple 6 x 6 cut into 3 x 3 peices and two simple tiles create an stylish floor. The floor had to be leveled first in this 80 year old house.
