No minimum dimensions under b/regs (unless you're replacing an existing WC on the ground floor in which case no smaller than that one, or compliant for new build in Approved Document M, whichever is least onerous).

cheers, it is a brand new wc in the new extention, i know the architect will know/advise but i was curious to know if there were minimum dimensions, prob wont matter as the boss now tells me she wants me to fit a normal size wc and a childs one (she is a childminder so will prob increase the room size to accomodate both
