Although it is sometimes relatively easy to locate basic newspaper reports by a visit to The British Library or reference to online sites, such as The British Newspaper Archive, local libraries can still be much stronger in local magazines, directories and, especially, pictures and ephemera.
Perhaps your own local (or national) library or archive has items relating to Victorian Turkish baths in the British Isles (or elsewhere in what was part of the 19th century British Empire).
If so, or if you would be prepared to enquire whether there are any, please contact us. We can then ensure that your time will be used most effectively by telling you what is already known, but not yet published on the site.
