Owning your own home

looks like it's the shower base, and slight gap when you get in. Water over time gets through and has probably now found its way through. I'll get it all sealed up, longer term I may need to remix shower base. What's leak like now?

From my upstairs neighbour on the leak. Not convinced, as bathroom was all resealed after the same leak the year before, and they tenants in the flat didn't shower night before the leak. The leak I think was also more of a one time event than a gradual worsening waterfall of doom from gradual water build up.
