Frummer (P) was a registered guest at the Hilton in London (D). While taking a shower, he slipped and fell and sustained serious injury. P charged D with liability under three theories; not providing a rubber shower mat after a specific request, failing to install grab bars, and not constructing the tub to minimize the risk of falling. D claimed that P was at fault from his own carelessness and offered expert evidence that it had done all that was reasonable or that was required under a reasonable standard. D won the verdict and P moved to set it aside and grant a new trial.
