Throwing a party in the garden, at a hired field, or in a marquee on private land? Once your guest list passes 30-40, the household bathroom stops being adequate — and asking guests to queue on the landing or trek through the house in heels and muddy shoes is not part of anyone's plan for a great party.

Portable toilet hire is the practical solution. Here is what every host needs to know.

When You Need Portable Toilets

The Triggers

  • Guest numbers: More than 30-40 guests and a single household bathroom will not cope
  • Duration: Events lasting more than 3-4 hours increase per-person toilet usage
  • Alcohol: A free bar or generous drinks service increases demand significantly
  • Distance: If the party is in a field, garden, or marquee that is more than a minute's walk from indoor facilities
  • House preservation: You simply do not want 80 people using your bathroom for 8 hours

The Maths

For a party with drinks:

  • Up to 40 guests: 1 portable toilet (supplement with household bathroom)
  • 40-80 guests: 2 portable toilets
  • 80-120 guests: 3 portable toilets or 1 luxury toilet trailer
  • 120-200 guests: 1 luxury toilet trailer plus 2 standard units

Standard vs Luxury: Which Is Right?

Standard Portable Toilets

  • Chemical flush, hand sanitiser, internal lighting
  • Self-contained — no power or water needed
  • Cost: £60-120 per unit for a weekend
  • Suitable for barbecues, casual parties, and informal gatherings

Luxury Toilet Trailers

  • Flushing toilets, running water, mirrors, heating/cooling
  • Interior finish comparable to a restaurant bathroom
  • Cost: £500-1,200 for a weekend
  • Suitable for milestone birthdays, engagement parties, anniversary celebrations, and any event where the host wants to impress

The Decision

If your guests are dressing up or the occasion is special, a luxury trailer is the right choice. If it is a barbecue, a bonfire, or a casual afternoon, standard units do the job.

Getting the Right Unit to Your Property

Access

This is the most common problem hosts encounter. Before booking, check:

  • Side gate or driveway width: Minimum 2.5m for a standard portable toilet delivery; wider for a luxury trailer
  • Overhead clearance: Low branches, washing lines, pergolas, and wires can obstruct delivery
  • Ground condition: The delivery vehicle (a flatbed truck or tow vehicle) is heavy. Soft lawns, gravel, and uneven surfaces can cause problems
  • Turning space: The delivery vehicle needs room to manoeuvre

If access is tight, discuss it with your hire provider at the time of booking. They deal with challenging deliveries regularly and may have solutions (smaller vehicles, carry-in service, alternative placement).

Timing

Have the units delivered the day before the party. This gives you time to:

  • Check that everything is working
  • Set up lighting and screening
  • Adjust placement if needed
  • Avoid the stress of a morning-of delivery that runs late

Where to Put the Toilets

The Ideal Location

  • Close enough: Within 30-60 seconds' walk of the main party area
  • Far enough: Not directly adjacent to the dining or bar area
  • Downwind: Position the units downwind of the event space
  • Level: On a flat, firm surface — patio, hardstanding, or well-drained lawn
  • Discreet: Screened from the main party area by hedging, fencing, or a temporary screen

Screening Options

  • Existing garden hedges or walls
  • Temporary bamboo or willow screens
  • Fabric panels on a freestanding frame
  • Large potted plants arranged as a visual barrier
  • Fairy lights or festoon lighting that doubles as screening and decoration

---

Power and Water

Standard Portable Toilets

None required. They are entirely self-contained.

Luxury Toilet Trailers

  • Power: A 13-amp domestic socket will run most small trailers. Use an outdoor-rated extension lead. Larger trailers may need a 16-amp supply or a generator.
  • Water: Most small trailers carry their own water tank, sufficient for up to 100-120 guests. For larger parties, a mains connection is preferable.

Keeping Facilities Fresh During the Party

Units are delivered fully serviced and stocked. For a single-day party, they will last the duration without professional servicing. However:

  • Check units every 1-2 hours
  • Restock toilet paper, soap, and towels as needed
  • Wipe down surfaces with antibacterial wipes
  • Empty waste bins if they are getting full

Keep a supply box near the toilet area with:

  • Spare toilet rolls
  • Liquid soap refill
  • Paper towels
  • Bin liners
  • Antibacterial wipes
  • Air freshener spray

Making It Special

For milestone celebrations and special occasions, these touches transform the toilet experience:

Inside the Unit or Trailer

  • Fresh flowers in a small vase
  • A basket of toiletries — hand cream, mints, plasters, hair ties
  • A scented candle (LED for safety) or reed diffuser
  • A small framed sign with a welcome message or humorous quote

Outside

  • A welcome mat or outdoor rug at the entrance
  • Festoon lights along the approach path
  • Potted plants flanking the entrance
  • A small chalkboard sign directing guests ("Loos this way →")
  • Ambient music from a weatherproof speaker

---

Lighting

If the party extends past sunset:

  • Festoon lights or fairy lights on the path to the toilets
  • Battery-powered LED lanterns at the toilet area
  • Solar stake lights along the edges of the path
  • Confirm that the internal unit lighting is working

Adequate lighting is both a safety requirement and a comfort factor. A dark, unlit path to the toilets will discourage guests from using them.

Costs

Portable toilet hire for a private party is one of the most affordable elements of the event:

| Item | Typical Cost |

|------|-------------|

| 1 standard portable toilet (weekend) | £60-120 |

| 2 standard portable toilets (weekend) | £120-220 |

| 1 luxury toilet trailer (weekend) | £500-1,200 |

| 1 portable hand-wash station | £50-100 |

Total cost for a typical 80-guest party: £120-300 (standard) or £500-800 (luxury).

Common Mistakes

Not Ordering Enough

The most frequent error. Use the ratios above and err on the side of one extra unit rather than one too few.

Forgetting About Access

A luxury trailer that cannot fit through your side gate is no use. Measure before you book.

Leaving It Too Late

Summer weekends are busy. Book at least 4-6 weeks ahead for standard units, 8-12 weeks for luxury trailers.

Ignoring the Weather

Rain makes paths muddy and slippery. Lay mats or boards on the approach. Have a plan for wet weather.

Skipping Hand Washing

A portable hand-wash station with running water, soap, and towels is inexpensive and makes a noticeable difference to the guest experience.

Checklist

  • Guest count and event duration confirmed
  • Number and type of units decided
  • Access route checked — width, clearance, ground, turning
  • Placement location chosen — level, discreet, downwind
  • Power and water arranged (if luxury trailer)
  • Screening planned
  • Pathway lighting arranged
  • Delivery confirmed for the day before
  • Collection confirmed for the day after
  • Supply box prepared — spare toilet paper, soap, towels, wipes, bin liners
  • Person assigned to check units during the party
  • Hire provider's emergency number saved

A well-planned toilet area means your guests are comfortable, your house stays clean, and you can enjoy hosting the party instead of worrying about the queue for the bathroom.
