The caterer is booked. The florist confirmed. The tent is reserved. And the venue has no indoor restrooms. That detail — quietly sitting in the contract addendum — becomes very loud the evening of the event when 200 guests are navigating an afterthought. TMI Portable Toilet Service plans for the part of the event nobody wants to discuss. And we make sure it doesn't become the part of the event everybody remembers.
From vineyard weddings to 300-worker commercial builds. From luxury estate events to ADA-compliant municipal contracts. One call handles the whole rental — delivery, servicing, and pickup included.
What unit type is right for a 175-person outdoor wedding? That answer depends on your venue aesthetics, your budget, and how much the restroom experience matters to the couple.
A construction site without adequate sanitation is an OSHA citation looking for a surface to land on. One compliant unit per 20 workers isn't a suggestion — it's the floor.
Standard rentals weren't designed for events where appearance is part of the product. When the venue is beautiful and the experience is deliberate, every detail has to match.
There's a significant difference between a standard porta potty and a flushable portable toilet — and for some events and projects in Montana City, MT, that difference is the right call.
No outdoor event or construction site should have restroom access that excludes anyone. For many project types in Montana City, ADA-compliant units aren't optional — they're required.
TMI quotes are fixed at confirmation. You approve a number. That's your number.
No reconciliation surprises at pickup. Ever.

Mid-rental servicing scheduled at booking on all rentals over five days
Unusable unit replacement dispatched within four hours of a confirmed issue

End-of-rental pickup on your scheduled date — no unit lingering past project close
The standard formula for portable toilet rental is one unit per 50 guests per four hours. Most event planners have heard that number. What they haven't heard is that the number changes as soon as alcohol enters the equation.
Alcohol increases restroom frequency by roughly 20 to 30 percent depending on the event type and service volume. On a four-hour event with an open bar in Montana City, MT, a crowd of 200 guests behaves like a crowd of 240 to 260 from a restroom demand standpoint.
Apply that math to a standard unit count and you're short. Not catastrophically — just enough to create lines that frustrate guests and reflect poorly on whoever planned the event.
The fix is simple: add one unit for every 40 to 50 guests instead of 50 when alcohol service is part of the event. For a 200-person open bar wedding, that means 4 or 5 units instead of 4. The cost difference is marginal. The guest experience difference is real.
TMI factors alcohol service into every event quote automatically. You tell us you're serving drinks — we adjust the count. No guesswork required on your end.
