Portable Toilet Placement Guide: Where to Put Units on Your Site or Event

Where you place portable toilets affects everything from worker convenience to service efficiency to guest experience. Poor placement leads to complaints, difficult servicing, and units that people avoid using. Good placement is invisible — people find the washroom easily, use it comfortably, and move on. Here are the practical guidelines.

Construction Site Placement

Within 200 feet of work areas. WorkSafeBC requires that washroom facilities be reasonably accessible. As a practical rule, place units within a 2-minute walk of where crews are working. If your site is spread out, use multiple units at different locations rather than clustering them in one spot.

Near break areas. Workers use washrooms most during breaks. Placing units near lunch tents, tool cribs, or break trailers reduces walking time and keeps workers on task.

On level ground. Portable toilets must sit on flat, stable ground. A unit on a slope can tip in high winds or become difficult to use. If your site has uneven terrain, we can recommend specific placement during delivery.

Away from excavations and active work zones. Keep units at least 15 feet from any open excavation, crane swing radius, or heavy equipment operating area. This is both a safety requirement and a practical necessity.

Accessible for service trucks. This is the most commonly overlooked requirement. Our service truck needs to reach every unit for weekly pumping and cleaning. Leave at least 10 feet of clearance behind each unit and ensure a path at least 12 feet wide for the truck. If we cannot reach the unit, we cannot service it.

Consider the season. In summer, place units in shaded areas when possible to reduce interior heat. In winter, south-facing locations that get sun help prevent freezing.

Event and Venue Placement

Visible but not central. Guests should be able to find the washrooms without a map, but the units should not be the first thing they see when arriving. Place them at the edges of gathering areas, near walkways, with clear signage.

50 feet minimum from food service. Health regulations in most Okanagan municipalities require a minimum distance between portable toilets and food preparation or serving areas. Fifty feet is a safe baseline. Some permits may require more.

Distribute units across the venue. For events over 200 guests, place units in at least 2 locations. This prevents long lines at a single bank of units and makes the washrooms accessible from all parts of the venue.

Near the entrance and exit. Place at least one unit or cluster near the main entrance. Guests often need a washroom right when they arrive or just before they leave.

Downwind from gathering areas. Standard portable toilets can produce odors, especially on hot days. Place them downwind of seating, stages, and food areas. Deluxe flushing units and luxury trailers have much less odor, so this is less critical for those unit types.

ADA units on firm, level surfaces. Wheelchair-accessible units need firm ground and a clear, level path from the main venue area. Grass can work if it is dry and firm. Gravel, pavement, or compacted ground is better. Avoid placing ADA units on soft ground, hillsides, or areas that could become muddy.

How Many Units per Location

Single unit: Fine for small residential construction sites (under 10 workers) or very small events.

2 to 4 units in a row: Standard for medium construction sites and events up to 200 guests. Place them side by side with about 3 feet of space between each unit.

5 or more units: Arrange in an L-shape or semi-circle rather than a single long row. This makes the cluster feel less like a wall of portable toilets and improves traffic flow.

Common Placement Mistakes

Blocking the units with materials or vehicles. On construction sites, portable toilets often end up boxed in by material deliveries, dumpsters, or parked equipment. Leave a buffer zone that stays clear.

Placing units on soft ground. Portable toilets are heavy, especially when the holding tank is full. Soft, muddy ground causes units to sink or tilt. Use plywood sheets under the units if the ground is soft.

Forgetting service access. If the service truck cannot reach the units, they cannot be pumped. This is the single most common placement issue we encounter. Always plan for truck access before placing units.

Placing all units in one location at a large event. This creates long lines at one spot while other areas of the venue have no facilities. Distribute units proportionally based on where guests will be.
