Lever-style faucets, which have one or two straight levers instead of round knobs, are a perfect style for a bathroom of someone who wants to age in place. That faucet style offers more benefits than that, though, and they would be a great choice in most bathrooms for three reasons. If you want a faucet that is easy to use and that won't create issues for those who are dealing with hand and arm issues, replace your faucets with ones that have lever-style handles.
One of the biggest advantages to installing a faucet with lever-style handles is that you can still easily turn the water on and off even if you have a hand injury. Knob-style faucet handles require a good grip and the ability to wrap your hand around the knob, which aren't very easy if you've hurt your hands. And it's not just an acute injury that you have to think about; chronic problems like arthritis in both hands can make faucets annoying to use. But with a lever, you just have to push and pull, and you don't need a lot of strength to do that.
Here's another reason to install a lever-style faucet: It's going to be much easier to wash your hands. If you've been cleaning with a slippery soap, giving your nails a little care with some olive oil, or using another such slippery substance, you can turn on the faucet to wash your hands without leaving gunk on the handle or seeing your fingers slip off the faucet knob. You could turn on the faucet with your elbow if you needed to. Yes, you could grab a tissue or cloth and try to turn a faucet knob with those, but why waste those? If all you have to do is wash off a bathroom cleanser from your hands, you shouldn't have to waste paper to do that. With a lever-style faucet, you just pull the lever toward you with the heel of your hand and wash your hands.
Better Leverage With Levers
Faucet handles that have been installed properly offer some resistance when you try to turn them on; they have to so that you don't accidentally nudge the faucet only to have a lot of water suddenly roar out. For knob-style faucets, that resistance can be kind of tough -- it's not difficult to move the faucet, but it's not the smoothest movement, akin to the initial jolt of movement when you first unscrew a tight cap on a jar -- and it can start to strip the screws inside the faucet assembly over time. With levers, you don't have that resistance -- good for those who have the aforementioned hand injuries or chronic conditions -- and there's less friction applied to the interior of the assembly.
Installing a faucet is easy to do yourself, but what's even easier is to have a plumber do it for you. It doesn't take long to change the assembly, so you can schedule the faucet installation even when you don't have a lot of time.
