I've got this small old bathroom that I want to lay with ceramic tiles. But to do that the walls should be straight - which they are not. Three of them are almost fine, but the fourth is... well, take a look at the pictures:
Left: front view at the wall;
Right: side view at the wall.
This isn't to scale, but you can see the idea. First of all there is a large towel-dryer in the middle of it, stretching almost all the way across. Secondly, the wall starts slanting away on the upper half.
I cannot remove the towel dryer because the people who designed the original plumbing system (probably dead by now) were... not very smart, to put it politely. It is attached to the central hot water supply in the apartment block and turning off the water means that everyone loses hot water. To make it better, even if I did turn off the water momentarily and remove the dryer, I'd still need to reconnect the open ends or the water flow would be broken (my above neighbour gets the hot water that has passed through my dryer). And last but not least - to turn off the water and do anything with the dryer I have to call the authorities and pay them $30 every time. Royal pain.
So... what would you suggest?
