Trailer prices are published starting prices we checked on Calgary-area rental sites in September 2026: $1,550 for a three-stall trailer, excluding delivery and water, and $1,795 a day or $2,295 a weekend for a four-stall trailer. Prices change, so confirm with a written quote.
Those are other companies' trailers. Ours, a two-stall, is quoted for your date and venue.
How many stalls or units your guest list needs depends on the count, the hours, and the bar. The wedding washroom calculator works it out with the working shown.
What the headline price leaves out
The biggest difference between quotes is usually what the first number leaves out. Ask every company, including us:
- Delivery and pickup. Some trailer prices exclude delivery entirely. We quote delivery with your date, based on the drive from Calgary, and list it in the quote.
- Water and power. Some trailers need a water hookup or a generator at extra cost. Ours carries its own fresh water and waste tanks and runs on standard power, or a generator where there is none. We fill it from a hose tap on site; water costs extra only when the venue has none.
- How many days. A Saturday wedding often means a Friday drop-off and a Sunday pickup. Ask whether that is one day or three. Ours has a multi-day rate for weekends and longer events.
- Servicing. Whether the unit is cleaned and restocked during the event.
- Deposits and tax. The booking deposit, any damage hold, and GST. Ours is a 50% deposit to hold the date and a refundable $1,000 hold the week of. Our quotes do not include GST.
When porta potties are the right call
We rent trailers and will still say it: for a short, casual, or very large outdoor event, standard units are often the sensible choice. For a wedding, where guests are dressed up most of the day and every one of them visits, the trailer is usually worth it. More in our honest side-by-side.
