Weird looking baths, never seen one like that before...
The partitions have been mostly ripped out leaving the strange layout you see - interestingly rather than glazed brick it was originally black terrazzo wall panels and dividers, the only colliery I've seen to use this.
The blue tiling has been whacked over the top when they knocked the partitions out, Possibly circa 2005 when they ripped out all the original Lockers and dragged the ones you see today over from Riccall as part of UK Coals re-use of Selby Coalfield fittings!
