I agree with this, atrocious provision at Clapham Junction. One time I was waiting to use the cubicle, a guy came out, and declared "Hang on, Im not done yet", as he went to get some paper towels, since there was no toilet paper....I would say Clapham Junction, one set of toilets, on the footbridge at the platform 17(?) end. If memory serves me correctly the gents only has one toilet and 3 urinals. Completely inadequate for a station that is this busy, and very very hidden away. I only found them one day, when I had nearly an hour wait for my train, and was thinking it would be simpler to take a train to Victoria/Waterloo, use the facilities there, and there catch a train back!
