Check the hours of existing bathroom access
Ask the venue which facilities are included and whether they are available outside guest hours. A public or neighbouring restroom should not be counted simply because it is nearby. Explain the remaining gap before choosing toilet types, washing and accessible options.
Keep supplier visits separate from guest arrivals
Review the approved entrance and timing with the property contact. Place facilities before other installations occupy the approach and retain access for attention and removal. Ask how changes are confirmed if the event runs longer or the venue timetable shifts.
Are nearby bathrooms actually part of your booking?
Check access rights and opening hours instead of assuming a neighbouring facility can support the occasion. Include setup and cleanup staff where relevant. Once the available facilities are clear, discuss the supplemental equipment and its approved position with the host and rental contact.
