They have open days when the public can visit, take the tour and then wander around at leisure - dates here. If you are within reasonable travelling distance I'd urge you to visit - this is a very, very special place.
History of the site here and an excellent article here.
Here is the start of the last linked article:
The Victoria Baths is a building of enormous historic and cultural value, in the heart of Manchester. Built in the 1900s, it provided washing and leisure facilities until its closure in 1993; private baths and laundry were housed there along with three swimming pools and the Turkish Baths.
If you watched the restoration series on television with Griff Rhys Jones you may remember that this won the first ever series back in 2003. It is still a work in progress and the plans are to open the baths once more for public use.This was my third visit to this wonderful place and was an organised visit just for our group of 30 people so we had plenty of space and room to ourselves. Enough with the words now on to the pictures.
