Few things in life are more horrifying than running out of toilet paper. If you’re living in France, Japan, Argentina, or a number of other countries outside the U.S., no problem: Just hop on the bidet. The contraption that looks like a cross between a toilet and a baby bath is more of a rarity in North American bathrooms, but if you want to reap its benefits at home, you won’t have to remodel the loo to do so. A handy bidet attachment that connects to your toilet will do the trick. Before you start shopping, there are three things to consider: 1) Do you want a mechanical or electrical bidet? The latter offers more functions, but the former, which uses your home’s water pressure, are generally less expensive. 2) Does it have a heated-water option? An attachment uses the same water source as the sink, so turning on the sink’s hot water first warms up the bidet after long periods of inactivity. 3) Is the nozzle self-cleaning? One that sanitizes itself will come in handy if you live with males who don’t have the best aim. Once you’ve answered these questions, you’re ready to begin.
