4-Stall Combo

A general rule: one shower stall supports 10-15 workers per shift with a 7-8 minute average shower time. For a 50-person crew, an 8-stall unit handles the load comfortably with staggered use. For 100+ workers, consider a 16-stall semi-trailer or multiple units. Tell us your crew size and shift schedule and we’ll recommend the right configuration.

Our 8-stall trailers with 300-gallon fresh water tanks support approximately 20 showers per fill (at 2.0 GPM flow rate, 7.5 minutes per shower, 15 gallons each). The waste tank handles 64+ showers before pump-out. Fresh water is typically the limiting factor — adding a Water Box extends capacity significantly.

For apartment buildings, 1-4 stall units are typical. A 20-unit building with staggered schedules usually needs a 2-stall trailer. Larger buildings (50+ units) may need a 4-stall or 8-stall unit. We’ll factor in your building size, number of residents, and expected duration.

Yes. Our 1-Stall ADA Combo includes a wheelchair ramp, grab bars, spacious interior for mobility devices, and meets full ADA compliance standards. It combines a shower and restroom in one accessible unit.

Service frequency depends on usage. For a typical 8-stall unit with 30-50 daily users, we service 2-3 times per week — pumping waste, refilling fresh water, cleaning interiors, and restocking supplies. High-traffic sites may need daily service. We match the schedule to your actual usage.

Each service visit includes waste tank pump-out, fresh water refill, interior cleaning and sanitizing, restocking of soap/shampoo/paper products, inspection of water heaters and climate systems, and a general condition check. Everything is included in your rental rate.
