Shelf above the kitchen sink

I thought it is a very good idea to add a utility shelf above the kitchen sink unit. I bought the shelf from Ikea and chose a colour that's matching the cabinet below. For the shelf shoulders, I chose red to give the place a bit of colour.
So I ask my own Handyman, J, to fix the shelf. The task proved to be difficult because the walls were so tough. I tried holding the electric drill with J to lend him some strength, and really felt that the job was so tough. Minute after minute of drilling, the vibrations running through your hand muscles, and still making hardly a dent into the wall tile.
Finally the job was finished after 2 hours. Here is the result.
I like it!
