Malmo Station toilets very expensive

The toilets on the station are quite difficult to find, they are on one of the platforms, but not that well signposted on the station, there was nothing obvious to show smene such as myself initially that they were the toilets,  They looked more like an office from outside with poor signage for those of us who do not speak Swedish.
The next shock was that you had to pay, 20 kroner,  about a pound in English money, I think they are the most expensive toilets I have ever seen, they had other facilitates such as showers but I think the cost was extra,
So when I went in, I expected something special, unfortunately they were just very functional,  I have to say they were clean, everything worked, but I dont think they warranted such a high charge when I have visited much better that were free
