Resident Evil Village is filled with gory scenes and grotesque monsters but there's still something deeply unnerving about something called the Ablution Room. This large bathroom is centred around a huge bath filled with blood, hopefully, surrounded by four statues. For anyone that has played a Resident Evil game before, these statues are obviously something that can be rotated and played with in some manner to progress. For anyone that hasn’t this can be a little overwhelming.

Either way, this guide will explain everything you need to do to solve the Ablution Room statue puzzles, and I promise not to make any more poo jokes. There aren’t any spoilers in this guide, besides mentioning that the Ablution Room exists inside Castle Dimitrescu though, so that’s good.
