Use the following guides to determine the recommended number of toilets required at your event.
These figures are for events where alcohol is available. If alcohol is not available, reduce the requirements in the table below by 50%.

| 9,000 - 10,000 | 11 | 15 | 30 | 9 | 50 | 10 |
| 10,000 - 11,000 | 12 | 16.5 | 33 | 9 | 55 | 11 |
| 11,000 - 12,000 | 13 | 18 | 36 | 10 | 60 | 12 |
| 12,000 - 13,000 | 14 | 19.5 | 39 | 11 | 65 | 13 |
| 13,000 - 14,000 | 15 | 21 | 42 | 12 | 70 | 14 |
| 14,000 - 15,000 | 16 | 22.5 | 45 | 13 | 75 | 15 |
| 15,000 - 16,000 | 17 | 24 | 48 | 13 | 80 | 16 |
| 16,000 - 17,000 | 18 | 25.5 | 51 | 14 | 85 | 17 |
| 17,000 - 18,000 | 19 | 27 | 54 | 15 | 90 | 18 |
| 18,000 - 19,000 | 20 | 28.5 | 57 | 16 | 95 | 19 |
| 19,000 - 20,000 | 21 | 30 | 60 | 17 | 100 | 20 |
Adjusting the number of toilets at an event:
| Duration of Event | Percentage of the table values (using the table above) |
|---|---|
| More than 8 hours | 100% |
| 6 - 8 hours | 80% |
| 4 - 6 hours | 75% |
| Less than 4 hours | 70% |
How to use the above tables: E.g. 12,500 tickets have been sold for a concert. The duration of the concert will be five (5) hours with alcohol being made available to patrons over the age of 18. Event organisers need to ascertain how many toilets will be required. Using the tables above, the following numbers can be identified:
Male Facilities:
| WCs | URINAL METRES | URINALS | HAND BASINS |
|---|---|---|---|
| 14 x 75% = 11 WCs | 19.5 x 75% = 15m | 39 x 75% = 29 urinals | 11 x 75% = 8 hand basins |
Female Facilities:
| WCs | HAND BASINS |
|---|---|
| 65 x 75% = 49 WCs | 13 x 75% = 10 hand basins |
NOTE: For events with no alcohol reduce the above numbers by 50%.
