How Many Stalls Do I Actually Need?
Four stalls hits the sweet spot between 2 stall restroom trailer setups made for smaller backyard gatherings and the 8 stall restroom trailer built for large festivals. If you're planning a wedding for 120 people, or running a construction crew that's grown past what standard porta potty rental units handle alone, four stalls usually covers it without long lines. OSHA 1926.51(c) sets toilet ratios for job sites, and once your crew count climbs past 20, that math starts favoring a trailer over a handful of single units. For weddings and private events, check our wedding restroom rental page for guidance specific to guest counts, and if you're unsure how many fixtures you need in general, the how many porta potties do I need guide walks through the numbers. Spokane hosts of outdoor weddings often pair a 4 stall trailer with a couple of standard porta potty rental units near a parking area for overflow.
What Does a 4 Stall Restroom Trailer Cost in Spokane?
Pricing depends heavily on how long you need it and whether it's a single-day rental or a full weekend or week booking. Delivery fees run separately and depend on distance and site access, similar to what applies on our restroom trailer rental page generally.
| duration | typical range |
|---|---|
| day | $175 to $2,500 |
| weekend | $900 to $3,000 |
| week | $150 to $1,650 |
| event | $2,499 to $3,899 |
These bands reflect actual measured data across Spokane rentals, not flat quotes, so your final number depends on trailer condition, add-ons and how far the delivery truck has to travel. For a full cost breakdown across trailer sizes, see restroom trailer rental cost. Delivery itself typically falls in a separate fee range, and a roll-off-style delivery for larger units needs about 60 feet of straight clearance behind the truck, so tight urban lots near downtown Spokane sometimes need a placement conversation before delivery day. If your event budget is tighter, comparing this against porta potty rental cost for standard units side by side helps some customers decide which way to go.
Is a 4 Stall Trailer ADA Accessible?
Not automatically, and this catches people off guard. Standard 4 stall trailers are built for speed and capacity, not wheelchair access. If your event needs accessible facilities, ADA Standards section 213.2 requires that where portable toilet units are clustered, at least 5 percent be accessible, with a minimum of one unit. ADA Standards 404.2.3 sets a minimum clear door opening of 32 inches, and 403.5.1 calls for a 36 inch clear route width, specs that a standard trailer stall usually will not meet. For events in Spokane that need to check that box, pairing your 4 stall unit with a dedicated ADA accessible porta potty is the simpler fix than trying to retrofit a trailer stall. Full detail on requirements lives on our ADA restroom requirements page. Some customers ask about a luxury restroom trailer instead, since higher-end units sometimes build accessible stalls into the layout from the start.
Does the trailer need a water and power hookup?
Most 4 stall trailers run on onboard water tanks and battery or generator power, so a hookup isn't required for short events. Longer bookings, a week or more, sometimes benefit from a hookup if one's available onsite. Ask about your specific unit's setup when you book.
How far in advance should I reserve one in Spokane?
Two to three weeks out is comfortable for most weekends, but wedding season and fall festival dates fill faster. If your event is within days, check emergency porta potty rental for what's available on short notice.
Can it be delivered to a residential driveway?
Usually yes, but the crew needs roughly 60 feet of straight clearance behind the truck for safe backing and setup. Tight cul-de-sacs or sloped driveways sometimes need a quick site check first. Mention your address type when requesting a quote.
What's included in the rental price?
Delivery, setup, pickup and one service visit are standard, with additional servicing available for multi-day events. Handwashing is typically built into the trailer's design, unlike a standalone handwashing station rental unit. Confirm exact inclusions when you book.
Do you serve areas outside Spokane?
Yes. Spokane Porta Pros delivers to Cheney, roughly 17.4 miles southwest, Mead at 10.8 miles northeast, and closer towns like Town and Country, about 4.6 miles north. Check service areas for full coverage.
