One downside of attending public festivals and outdoor fairs - having to use a portable toilet - will soon be less common in North Charleston because the city is buying a big bathroom on wheels.

Unlike those plastic outhouses with no lighting, the city's portable potties sound pretty plush.

The city's tow-able toilet trailer will offer restrooms for men and women with air-conditioning, working sinks and toilets that flush.

North Charleston City Council has tentatively agreed to buy a 10-unit trailer, which includes a handicap-accessible restroom, for just over $60,000 from Comforts of Home Services of Montgomery, Ill.

"Our toilet trailers are great for weddings, birthday parties, corporate functions, sporting events, construction projects and anywhere else temporary restrooms are needed," the company says, on its website.

City Director of Recreation Ed Barfield said the city currently spends $700 to rent a portable restroom trailer for events, and there are about 35 events yearly where one could be needed. Portable restrooms with handicap access cost $1,400 to rent, he said.

Mayor Keith Summey said the toilet trailer will pay for itself in about three years, and the city may buy a second one next year.

Comforts of Home Services suggests that nice bathrooms make for more profitable festivals.

"Our luxury toilet trailers will help retain many of your attendee's for a longer period of time," the company says on its website. "They won't run off in search of cleaner restrooms, thus providing more potential revenue for you!"
