The bathroom was renovated sometime late eighties or early ninetees, so I didn't make any major work here. However, the ugly very narrow door to the hallway, that also tilted dangerously, was my target.
Here you can see how many layers of floors have accumulated over the years. At least three different floors!
Here you can see the new door frame and the temporary destruction to widen the door. It was tricky because the wall was built up using very porous blocks.
Here's the new door in place. About 10 cm wider and with looks to match the rest of the appartment.
