• Event-grade units with sinks and upgraded interiors
• Hand-washing stations for food service
• Restroom trailers for weddings and formal events

Planning Lowcountry weddings and festivals

Charleston is one of the busiest wedding destinations in the Southeast, and many ceremonies take place at waterfront homes, barns and historic estates without enough indoor restrooms. Restroom trailers are a popular choice for these events, but they need level ground, a clear path for the delivery vehicle and sometimes a power source.

Spring brings Spoleto Festival USA and a run of food and wine gatherings, while fall and winter bring oyster roasts and church events. Book early for peak weekends and review our event sanitation checklist.

Job-site restrooms for Charleston construction

New homes on Johns Island and Daniel Island, commercial projects in North Charleston and renovation work on the peninsula all need on-site sanitation. Contractors typically keep one or more units for the life of the project, with regular weekly service. Downtown sites may have little room, so a compact unit placed off the sidewalk is common. See commercial site restrooms for longer projects.

Servicing in heat, humidity and storms in Charleston

Charleston summers are hot and humid, which increases odor and fill rates. For busy sites or multi-day events, ask about more frequent servicing and placing units in partial shade. When a tropical storm is forecast, providers may secure or remove units, and service can pause until roads reopen. Our maintenance guide explains what servicing includes.

Placement and access on tight lots in Charleston

Service trucks need to reach each unit, ideally within a short hose distance. Place units on firm, level ground away from marsh edges and low spots that flood. On the peninsula, coordinate with neighbors and keep units off public sidewalks unless you have permission. Provide an accessible route to at least one ADA unit for public events, and keep restrooms a reasonable distance from food prep areas.

How many units to order in Charleston

For construction, OSHA 29 CFR 1926.51 sets a baseline: one toilet for up to 20 workers, and more as crews grow. For events, the right count depends on headcount, duration and whether alcohol is served. Our unit planning guide walks through common scenarios, and your provider can help adjust.

A few Charleston-specific adjustments help. Outdoor weddings with a cocktail hour see heavy use in short bursts, so an extra unit or a larger trailer prevents lines. Multi-day festivals on the waterfront may need mid-event servicing rather than more units. On renovation jobs with several trades on site at once, count the peak crew size, not the average, and add a unit if subcontractors overlap for weeks at a time.
