I did the same for the doors of the oven and microwave. For contrast, I decided to color the doors in black paint.
Then I made holes in the TROFAST frame to fit the sink, faucet and cooktop. To do this, I first used a drill to make a few holes along the cut line. Then I inserted the blade of my jigsaw into the holes and cut it out.
With the holes and cut lines sanded down, I installed the sink, faucet and cooktop in their place.
Next, for some hanging storage, I set the BYGEL rail under the TROFAST wall unit.
After that, I fixed the doors with hinges and magnets.
The last thing was to put the whole thing together. I assembled it with a little help.
