It starts with "it's just a porta potty — it doesn't matter that much."
Then the event happens. Or the job site runs for six weeks. And what seemed like a minor detail becomes the thing that defines the experience — for your guests, your crew, or your client who toured the site on week three.
Thompson Roll Off Service treats portable sanitation the same way we treat roll-off rentals: with the same attention to matching the right unit to the situation, the same commitment to delivering on time, and the same standard for what a clean, functional unit looks like on arrival.
What you get isn't just equipment rental. It's the confidence that the sanitation side of your project is handled by the same team that handles everything else.
Built for job sites. Durable enough for active use by rotating crews. Chemical treatment controls odor. Hand sanitizer dispenser included. Ventilated to reduce heat buildup in summer.
OSHA minimum: 1 unit per 10 workers on sites with 20 or more employees.
A step up from the standard unit without the footprint of a trailer. Water-flush mechanism. Better odor management. More comfortable interior dimensions.
Required at many permitted events and commercial construction sites. Wider entry door, interior grab bars, ground-level threshold, and turning radius clearance for wheelchair users.
Note: Many event and construction permits require at least one ADA unit by default. Confirm requirements before booking.
This is where the portable sanitation category changes entirely. Climate control — both heat and air conditioning. Running water at the sink. Soap dispensers, paper towels, vanity mirrors. Individual locking stalls with interior lighting. The experience is indistinguishable from a fixed indoor restroom.
Guests will not know they're using a rental unit. That's the goal.
All the features of the 2-stall with higher throughput for larger events. Often configured with separate men's and women's sides. Suitable for events over 150 guests or where restroom access is a primary logistical concern.
Setup note: requires a level surface and access clearance for tow vehicle.
Fresh water tank, soap dispenser, paper towel holder, and waste water collection. Available as a standalone unit or attached alongside any toilet unit.
A combined unit for situations where standard bathing facilities genuinely aren't accessible.
Most rental companies quote the minimum. We quote what works.
Start with 1 unit per 50 guests for a 4-hour event. Add 1 unit per 50 guests for every additional 4 hours. Then adjust:
1 unit per 10 workers on sites with 20 or more workers. Under 20 workers, at least 1 unit if permanent facilities aren't nearby. Mixed-gender crews: consider unit arrangement accordingly.
When in doubt, call us with your headcount and event or project type. We'll give you a recommendation based on experience.
A property in the Pennington Gap area — stunning setting, no permanent restroom infrastructure. 200 guests. We delivered a 4-stall luxury trailer and three standard units the day before the event. Trailer serviced and freshened for the evening reception. Pickup scheduled for 8am the following morning. Not one guest comment about restroom access. That's the standard.
A Pennington Gap, VA commercial property undergoing full interior renovation with crews of 20–35 workers throughout. We deployed four standard units and a handwashing station at project start, adjusted to five units when crew expanded in week four, and provided weekly servicing throughout. The client later commented that sanitation was one of the few things on the project that never came up as a problem.
A two-day outdoor fundraiser in Pennington Gap with approximately 450 attendees per day. Ten standard units and two ADA-accessible units deployed across two restroom areas on the event grounds. Serviced midday on both days. Picked up the morning of day three. No queuing complaints — the organizer rebooked for the following year before we'd pulled out of the lot.
"We used Thompson for both a dumpster and portable restrooms for a large landscaping project in Pennington Gap, VA. Having one company handle both meant one call, one delivery window, and one contact when the project ran a week long."
— Anthony K., Landscape Contractor
"I booked a luxury restroom trailer for my daughter's wedding. I'll admit I was skeptical. When it arrived and I walked through it, I stopped worrying entirely. Our guests never would have known. Thompson delivered it clean and on time."
— Patricia O., Mother of the Bride
"I manage job site logistics. We've had issues with other companies not servicing on schedule. Thompson services when they say they will, every time. That's what I pay for."
— Rodney F., Construction Project Manager
The logistics of portable restroom placement are rarely covered in event planning guides. They should be. Bad placement creates lines, confusion, and complaints.
Principle 1: Visibility without intrusion. Restrooms should be easy to spot from the main event area — but not positioned where they dominate the sightline or the photos.
Principle 2: Downwind when possible. In open outdoor settings, check the prevailing wind direction for the time of day relative to food and seating.
Principle 3: Separate clusters for larger events. For events over 150 guests, split restroom capacity across two locations rather than concentrating all units in one area.
Principle 4: ADA unit placement requires separate thought. Accessible units need the most level and accessible approach path. Don't place them on uneven ground.
Principle 5: Access for servicing and pickup. The delivery vehicle needs to reach the units for multi-day service and for pickup.
A: For standard units, 2–3 weeks is workable outside of peak season. For luxury restroom trailers, 4–8 weeks is safer — particularly for spring and fall weekends in Pennington Gap, VA, which fill quickly.
A: Service visits include waste pump-out, interior cleaning, restocking of consumables (toilet paper, hand sanitizer or soap), and a condition inspection.
A: Yes. We coordinate both deliveries when both are booked together. It simplifies your logistics significantly and ensures both arrive in the same window.
A: Yes — luxury trailers typically require a 110V electrical connection for lighting and climate control. If your location doesn't have power, there are options we can discuss.
A: Call us as soon as you know. Adding a unit is generally straightforward with adequate lead time. Last-minute additions are harder to guarantee.
