Having a dual showerhead in your shower solves a lot of problems that can come up. You may want to shower with a fixed showerhead, but you may also like the versatility of using a handheld showerhead. With a dual showerhead, you can use both at the same time if you wish. You can also use your shower to clean kids and pets without having to give up your fixed showerhead. Many people like to shower with their fixed showerhead while using a handheld unit to rinse off their hair or other areas. This can easily be done with a dual showerhead. A handheld unit is especially helpful for young kids who aren't old enough to stand up in the shower and bathe. The handheld portion of the showerhead is helpful for making a child's bathing session go quickly and easily.
Using a kitchen faucet can be difficult when it's a traditional faucet that simply sprays water straight down. When you have a kitchen faucet with a built-in sprayer that pulls down from the rest of the unit, you have better versatility from the faucet. It's often hard to clean out the sink when you only have a traditional faucet. The spray of water simply doesn't go everywhere that you want it to. But when you have a kitchen faucet with a pull-down sprayer, you can use the faucet sprayer to spray any areas that you want. It makes it much easier to clean the sink as well as items that you put into the sink. Having a sprayer allows for powerful streams to rinse off smaller items and allows for faster cleaning. There is no end to the number of ways that you can use it.
