Think about the last big event you attended. You probably remember the food, the music, maybe the venue. Now think about the worst restroom you have ever used. That one sticks even harder, doesn't it?
Guests forgive a late caterer. They rarely forgive a dirty toilet or a two-hour queue. That is why it pays to plan before you rent portable toilets, not the night before your event.
This guide covers what types are available, how many you need, what affects the price, and what to check before you sign anything. It also explains why accessible units deserve a place in your plan.
Types of Portable Toilets You Can Rent
Not all units are the same. The right choice depends on your crowd, your budget, and the kind of event. At K & S Toilets, we supply clean, well-maintained units across Mid Wales, so here is how our range fits different jobs.
Construction Site Toilets
Building sites need toilets that are tough, easy to service, and ready on day one. Our construction site toilets are simple, sturdy, and affordable, and they suit sites of any size. Whether you are running a small renovation or a long-term build, we deliver on time and keep everything clean and working.
Portable Event Toilets
Planning a family party, a festival, or a sports day? Our portable event toilets are made for crowds. We can help you work out how many units you need for your guest numbers, so nobody ends up waiting in a long queue.
Handicap Portable Toilet Rental: 'Easy Access' Units
Accessible units are built larger, with a wide door, level entry, grab bars, and enough room to turn a wheelchair. Our Easy Access disabled toilets are available for events, sites, and public gatherings. If you are looking into handicap portable toilet rental, we can add an accessible unit to any booking. We cover the details of what makes a unit truly accessible later in this guide.
This is the part most hosts forget.
Picture guests who use a wheelchair. They traveled a long way to be at your event. They sit through the ceremony, eat, and chat. Then they need the restroom, and every unit has a step and a narrow door.
They will not complain. They will just leave early, and you may never know why.
A proper handicap portable toilet rental unit fixes this. Here is what makes a unit truly accessible:
- A wide door that a wheelchair can pass through
- A ramp or a level entrance with no step
- Grab bars near the seat
- Enough floor space to turn around
- A lock and handle that are easy to reach
You should plan for at least one accessible unit at any public event, a workplace site, or a gathering where elderly guests or people with mobility needs are likely to attend. Even at a private family function, it is a small step that shows real care. Some places also have rules that require accessible facilities for public events, so check what applies in your area.
Urinals
For busy events with large crowds, urinals are a smart addition. They move people through faster and take pressure off your standard units.
How Many Portable Toilets Do You Need?
This is where many people guess, and guessing usually goes wrong.
A simple starting point is one toilet for every 50 to 100 guests. But the real number depends on how long the event runs and whether food and drinks are served. Guests use restrooms more at long events and when alcohol is served.
| Guests |
Event length |
Suggested units |
| Up to 50 | 3 to 4 hours | 1 to 2 |
| 100 | 4 to 6 hours | 2 to 3 |
| 200 | 4 to 6 hours | 4 to 5 |
| 500 | Full day | 8 to 10 |
If your event runs longer than four hours, add extra units. Also add one accessible unit on top of these numbers, not instead of them.
It is always better to have one toilet too many than one too few. A long queue spoils the mood faster than almost anything else.
What Affects the Cost of a Mobile Toilet for Rent?
If you search for a mobile toilet for rent, you will notice that prices vary a lot. That is because several things change the final number:
- Type of unit. Standard cabins cost less than luxury units or trailers.
- Rental duration. One day costs less than a week or a month, though longer rentals often work out cheaper per day.
- Number of units. Renting more usually brings a better rate per unit.
- Delivery distance. A remote location costs more to reach.
- Servicing. Cleaning and waste removal during the rental can be extra.
- Add-ons. Hand wash stations, lighting, and fragrance options add to the bill.
The cheapest quote is not always the best one. Ask what is included, and get it in writing. A low price that leaves out delivery or cleaning can end up costing more.
7 Things to Check Before You Rent
Before you confirm with any company, run through this list:
- Is delivery and pickup included in the price?
- Is cleaning during the event included? For long events, this matters a lot.
- Are units cleaned and sanitized before they arrive?
- Do they have accessible units?
- What happens if something goes wrong? A good provider has a backup plan and a phone number that gets answered.
- What are the payment and cancellation terms?
- Can they show past work or customer reviews? Photos from real events tell you more than a sales pitch.
A provider who answers these clearly and without fuss is usually a good sign.
Placement and Setup Tips
Where you put the toilets matters almost as much as how many you rent.
- Choose flat, firm ground. Soft or uneven soil is a problem, especially after rain.
- Keep units away from the food and seating areas, but not so far that guests feel lost.
- Make sure the path is well lit if the event runs into the evening.
- Leave space for the service vehicle to get in and out.
- Put signs up so guests can find them easily.
Also book early. Wedding season, festivals, and holiday weekends fill up fast, and the best units go first.
Common Mistakes to Avoid
- Most problems come from the same few slip-ups:
- Booking too late. You get fewer choices and often pay more.
- Renting too few units. Long queues are the top complaint at events.
- Forgetting accessibility. It is easy to overlook and hard to fix on the day.
- Choosing only on price. Cheap can mean dirty, late, or unreliable.
- Not asking what is included. Surprise charges are common when nobody asks.
Frequently Asked Questions
How much does it cost to rent portable toilets?
It depends on the unit type, how long you need it, how many you want, and where the event is. Standard units cost the least and luxury trailers cost the most. Ask for a full quote that lists every charge.
How many portable toilets do I need for 200 guests?
For a typical event of four to six hours, plan on four to five units, plus one accessible unit. Add more if alcohol is served or the event runs long.
What is the difference between a portable toilet and a mobile restroom trailer?
A portable toilet is a single cabin. A trailer is a vehicle with several private stalls, and it often has sinks, mirrors, and better lighting. Trailers feel more like a real restroom.
Can I rent a handicap portable toilet for a one-day event?
Yes. Most providers offer accessible units for a single day or for longer periods. Book early, since fewer of these are available.
How early should I book a mobile toilet rental?
Two to four weeks ahead is a safe window for most events. For weddings and festival dates, book even earlier.
