Where is the door? Does it swing open outwards, is it reversible? What width? Also, have seen mention of needing 400mm access around sides for installation and servicing...we are looking to fit ours into a corner so how would this work? Thanks.

The door on the unit is front and center and is a 'sliding door'. This door can be fitted to open 'left to right' or 'right to left'. 

The golden rule is that you MUST have access to the back of the shower at all times during the build for the pipes and connections. This means you MUST be able to get down at least one side to get to the back. Once built and fully finished, the item then slides back against the wall/corner. You SHOULD NOT then block the item in with sinks/toilet that restrict future access
