The Vaults is a unique, multi-space venue located in a series of railway arches and tunnels beneath Waterloo Station. It does not feature traditional fixed seating levels like Stalls or Circles. Instead, each production customises the space, meaning seating arrangements, if any, are entirely temporary and variable. The stated seating capacity of 200 is a general maximum for a seated configuration, but many productions are immersive, standing, or promenade experiences with no fixed seating.

Seating Quality & Legroom: When seating is provided, it typically consists of temporary chairs, benches, or stools. Comfort and legroom vary significantly based on the specific production's design and the type of temporary seating used. people should expect a more utilitarian seating experience compared to traditional theatres.

Views of the Stage: Views are highly dependent on the specific vault used and the production's staging. Many shows are immersive, meaning the 'stage' can be all around the audience, or the audience may be moved through different spaces. Traditional proscenium arch views are rare. Sightlines can be dynamic and may be partially obstructed by architectural features of the tunnels (e.g., pillars, low arches), or other audience members, especially in standing or promenade productions. The experience is often designed to be intimate and unconventional.

Architectural Layout: The venue's layout is characterised by its raw, industrial aesthetic – exposed brickwork, concrete floors, and varying ceiling heights. The atmosphere is often dark, atmospheric, and immersive. Audience members may be required to stand, walk, or navigate uneven surfaces. Accessibility can be challenging due to the underground location and the nature of the tunnels; specific accessibility information should always be checked with the venue for each individual show.

Potential Restricted Views: Due to the non-traditional nature of the space and often immersive staging, 'restricted views' are less about specific seats and more about the dynamic nature of the experience. people should be prepared for varying perspectives and potential partial obstructions as part of the immersive design, rather than fixed 'bad seats'.
