Here you can see the tiles that Alma choosed. Just say if you are in doubt or if something is unclear.
Here is a little inspiration video how to set up tiles without using too much cement.
Walls in all the 3 bedrooms:
Walls in the hallway (atubangan)
Floor in small bedroom (beside Almas bedroom)
How many cement? And what price/sack.
Do you need any tools or other equipment to do the work?
