Hello!
I've started fixing up my basement where a drain was installed to make a small toilet. However, this was done some time ago and the concrete floor wasn't level, which I've now corrected. Now remains the other problem where the walls are not straight.
I measured with a spirit level and found a difference of up to 5-6 cm in some places. Would plastering be suggested or what would you skilled craftsmen recommend? It will take many bags and time
