How Many Portable Toilets Do I Need For An Event? (2026 Guide)
A simple, planner-tested ratio that works for weddings, festivals, markets and construction sites — plus when to upgrade to VIP units.
Under-quoting toilets is the single most common event-planning mistake we see. Queue too long and guests stop drinking, leave early, or worse — go behind the marquee. Over-order and you've wasted budget. This guide gives you the ratios used by professional event planners across Pretoria, Centurion and Johannesburg, plus a quick calculator you can use right now.
The quick ratio (memorise this one number)
For events serving alcohol over 4 hours, plan for 1 portable toilet per 50 guests. For dry events, 1 per 75 guests. Add 20% if 50%+ of guests are women, because cubicle dwell time is roughly double.
Detailed planning table
| Event type | Duration | Toilets per 100 guests |
|---|---|---|
| Wedding (alcohol) | 5–8 hours | 3 standard + 1 VIP |
| Corporate function | 3–5 hours | 2 |
| Festival / concert | 8+ hours | 4 |
| Market / pop-up | 6 hours | 2 |
| Construction site | 8h/day | 1 per 10 workers |
| Sports event | 4 hours | 2 |
When to upgrade to VIP toilet trailers
Standard portable toilets are excellent for festivals, markets and construction. For weddings, upmarket corporate events, or anywhere guests are dressed up, a VIP toilet trailer with running water, mirrors, lighting and flushing porcelain is the right call. Most planners we work with order 70% standard + 30% VIP for large weddings.
Five mistakes that cause queues
- Forgetting that bar service doubles toilet use after hour 3.
- Placing all units in one spot — split them across the venue.
- Skipping handwash stations (one per 4 toilets is the SA norm).
- No lighting at night — guests avoid dark cubicles.
- Ordering on event day. We always hold stock, but Saturdays in peak season book out 2–3 weeks ahead.
Delivery, placement and removal
Fumuno delivers across Gauteng — Pretoria, Centurion, Midrand, Sandton, Johannesburg, the East Rand and out to Hartbeespoort. Units arrive cleaned, sanitised and stocked. We position them on a level surface near (but not next to) the bar, with handwash stations within line of sight.
