A wedding dinner in a hall or hotel has built-in toilets. A wedding on a lawn, a kampung compound, a resort field or a marquee usually does not. The question every couple and planner asks is the same: how many portable toilets are enough? Too few and you get long queues in your wedding photos. Too many and you pay for units nobody uses. This guide gives you a number you can plan around.
The basic rule: guests and hours
The number of toilets depends on two things: how many guests you have and how long they stay. A short reception where people arrive, eat and leave needs fewer units than an all-day open house where guests come and go for eight hours.
As a starting point, plan about 1 unit per 50 guests for an event of up to 4 hours. For a full-day event, plan about 1 unit per 30 to 35 guests, because every guest uses the toilet more often over a longer day. If you are using VIP or premium units, a lower ratio of about 1 per 20 guests keeps the experience comfortable.
Quick reference by guest count
Use this table as a starting point. It follows the same ratios as our toilet calculator.
| Guests | Up to 4 hours | Full day | VIP / premium |
|---|---|---|---|
| 100 | 2 units | 3 to 4 units | 5 units |
| 200 | 4 units | 6 to 7 units | 10 units |
| 300 | 6 units | 9 to 10 units | 15 units |
| 500 | 10 units | 15 to 17 units | 25 units |
These are estimates for planning, not a promise. For a number tailored to your event, use the calculator or send us your guest count and timing and we will confirm.
When to add more units
Some events put more pressure on toilets than the basic rule allows. Add units if any of these apply:
- A long sit-down dinner where everyone leaves the table at the same time, such as during speeches or between courses.
- Lots of drinks, or an open house where guests stay for many hours.
- A mostly female guest list. Visits usually take longer, so set aside more units for ladies.
- Children, elderly guests or guests with limited mobility, who need more time and easier access.
- Rain forecast. Guests crowd under cover and queues get longer.
Standard units or VIP units?
Standard portable toilets are practical and cost less, which makes them a good fit for large casual gatherings and back-of-house crew use. For the main guest toilets at a wedding, many couples choose VIP units. Our Boudoir VIP and The Lux Premium units have a decorated interior, air conditioning, vanity mirrors and premium fittings, so guests do not feel they are using a portable toilet.
A common mix is VIP units for guests and one or two standard units for caterers, band and crew. That keeps the guest experience nice without paying VIP rates for every unit.
Where to place the toilets
- On firm, level ground. Avoid soft grass that turns to mud if it rains.
- Close enough that guests can find them easily, but away from the dining area and the main photo spots.
- Well lit for evening events, with a clear path to the door.
- With space for the delivery truck to reach the spot before the event and to collect afterwards.
- Tell the venue early. Some venues have rules about where units can go.
When to book
Wedding dates cluster on weekends and school holidays, and the best units go first. Book as soon as your date and venue are fixed. When you ask for a quote, give us the venue address, the date, the start and end time, the number of guests and whether you want VIP units. Delivery, installation, servicing and collection are part of our rental, so you do not need to arrange them separately.
