Visited with Silverstealth.. can't find any history at all on this place. Opened in 1890 and probably has been closed for 5-10 years given the way the building is falling to pieces inside. No pools to be found inside either, it looks like it may have been filled for use as a sports hall or it may have been attached to the right of the building and demolished some years back. The turkish bathrooms upstairs are rather nice thou.
Few more here:
