Portable Toilets: How Many is Too Many for My Outdoor Wedding?

Finding the perfect venue for your outdoor wedding can take ages, but once you do, you feel that the rest of your wedding will be just as perfect as the space. But don’t be fooled by that ideal spot—you may find the restroom facilities sorely lacking, or even nonexistent! Planning for all of the amenities you’ll need at your wedding can be bewildering. You don’t want to overplan and wind up paying more than necessary, but you also don’t want to underplan and not provide enough restrooms for you and your guests. Most importantly, you need to prepare accurately for the amount of expected guests. You’ll also want to consider what type of restrooms you want to provide. Here’s how to decide how many portable toilets you’ll need and what kind will suit you best, getting you one step closer to the wedding of your dreams.

How Many Portable Toilets Do I Need?

Outdoor weddings can be a challenge when it comes to figuring out how to provide amenities. You certainly don’t want to fall short when it comes to restrooms! Not having enough bathrooms at your wedding can leave guests feeling uncomfortable, annoyed with having to wait in long lines, or even finding other places to relieve themselves!

Once your guest list is finalized, you should have a fairly accurate idea of how many people will be in attendance. A good rule of thumb is that you should include at least one portable restroom for every 100 guests, or, if you have the available budget and want to err on the side of caution, one for every 50 guests. If you are still unsure of how many portable restrooms you may need to rent, check out On Site’s porta potty calculator for some extra assistance.

Another factor to take into consideration is whether or not you’ll be serving alcohol. Providing drinks will likely increase the amount of liquids your guests will consume, and since alcohol is a diuretic, it will also cause them to frequent the restrooms more!

Types of Portable Restrooms

After you have figured out how many restrooms you will likely need, it’s time to determine the right type. There are several options out there to choose from for special events like weddings: you can go with standard porta potties or even opt for a luxury restroom trailer.

Standard Porta Potty

With a standard special event porta potty, all units are delivered clean, sanitized and ready to use. This event staple is perfect for servicing events with thousands of people, but is also small enough for a more intimate setting. With a standard porta potty, you may be worried about its appearance throwing off the mood of your wedding—but with a little creativity and decoration, you can create something that flows seamlessly with your theme, and no one will even notice there are porta potties around.  

Luxury Restrooms Trailers

If you are particularly worried about the aesthetic appeal of a standard porta potty, or even just want something a little more traditional and elegant, then a luxury restroom trailer could be just what you need. With a large range of size and functionality offerings, luxury restroom trailers can accommodate the bathroom facility needs for your wedding. These trailers are fitted with flush toilets and running water sinks, making them feel more like a traditional bathroom rather than your basic porta potty. If you’re looking for something even more luxurious, some of our larger restrooms offer heating and air conditioning, stereo systems, porcelain sinks, and individual stalls.

Other Accessories

If you opt to go with standard porta potties, you may want to consider offering some other sanitation amenities as well. Having a place to wash your hands, such as a hand washing station or SaniSink, is important for guests to feel clean and comfortable. Another vital option is to have handicapped accessible restrooms for those who might need a little extra room. These can either come standard or as a feature in an ADA luxury restroom trailer. Lastly, you’ll want to consider providing a baby changing station for parents and guardians with young children.
