Getting married outdoors is more popular than ever. An alfresco celebration offers scenic beauty with natural lighting and greenery to boot. But unless you plan to elope and run, you can’t just set up in a local park on a whim. You’ll need to budget for equipment and supplies to host your guests in style and comfort. Keep reading to learn about four items that no outdoor wedding should lack.

1. Tent Rentals

Unless your site already has a covered event space, you’re going to need a tent. Sudden storms aside, an outdoor shelter makes your space much more comfortable than sitting directly in the hot sun. Your guests don’t need to worry about baking in the heat and getting fried by UV rays. And while a tent won’t stop all the critters from heading for your food and drinks, it can slow down most four-, six- and eight-legged invaders.

A Practical Wedding mentions that vendors’ quotes for tent rental should also include setup and breakdown plus delivery and permit costs. According to Wedding Wire, event rentals currently average around $650 in the United States. Accounting for regional price differences, you’ll probably pay somewhere between $425 and $1,000. Don’t forget to ask about flooring when getting your quotes.

2. Power Supply

Martha Stewart Weddings mentions inverter-style generators are ideal for powering lights, sound equipment, food storage, fans and anything else requiring electricity when getting married outdoors. Non-inverter generators aren’t robust enough to power lots of equipment. But if all you have are a few small twinkling lights, they can supply enough juice for those. Expect to pay between $200 and $1,000 per day for rentals, depending on your generator’s size and power output.

3. Water and Restrooms

Restrooms and water go together, of course. While you don’t have to club them together in your budget, you will need both for an outdoor site without proper access. Your food and beverage costs likely include drinking water and ice, but a water truck can supply for cooking, cleaning and restrooms. Keep in mind that some portable restroom vendors provide water tanks with their facilities.

Many water trucks hold around 6,000 gallons. Most charge by the truckload. Prices can vary, usually ranging between $180 and $400 per truckload. These costs may or may not include travel fees, so be sure to ask vendors when contacting them for quotes. As for portable restrooms, most go for about $75–$100 per hour. If you opt for restroom trailers, these can range between $1,000 and $5,000 each.

4. Dining and Lounge Furniture

If you’re setting up an outdoor venue from scratch, you’ll definitely need furniture. Event rental providers typically offer both tents and furniture, and you may be able to score a package deal. But you’ll want to consider a couple of things when getting furniture quotes.

Wayfaring Weddings estimates that chair rentals can cost between $1.50 and $6.00 each. Meanwhile, tables can range from $6.00 to $14.00 each. Remember that you may need to factor in setup and delivery costs, plus additional expenses for sashes and other chair decor.

In another short blog post, Brittany of Wayfaring Weddings breaks down average lounge furniture rental prices: up to $200 per sofa, $100 per armchair and $75 for end tables. Coffee tables, lighting, and other extras can run you more. Remember to ask about delivery, setup and other fees when getting vendor estimates.

A Detailed Checklist for Smart Planning

Getting married outdoors involves a little more planning than an indoor celebration. It’s important not to forget essentials such as a tent, water, electricity, restrooms and furniture. Wedding Wire’s Caitlin Krebs mentions other needful items, but the basic logistics will comprise a good portion of your reception budget.  With a comprehensive checklist, you can ensure that you don’t forget the important stuff for keeping guests happy and comfortable.
