Do you have a leaky faucet that just won’t stop every time you turn off the water? Unfortunately, this is a common occurrence for faucets after several years of daily use.
Fixing a leaky single handle faucet isn’t that hard of a repair, and it’s made even easier with a repair kit, it has all the parts you’ll need.
Types of Leaks
Your leaky faucet might be dripping cold water or hot and cold, knowing which one it is will help. The leak could just require tightening up one side of the faucet valves.
Fiddle with the faucet handle to determine if it’s leaking on both sides or not.
Bathroom Faucet Styles
If you need to upgrade your current faucet, worry not because there are many types of bathroom sink faucets to choose from.
Button faucets, as the name implies, don’t have the traditional handles associated with a sink, instead, you push a button to turn on the water and shut off the water. Although the button, button option can be confusing when first using one, their ease-of-use makes them quite desirable.
Many of the button faucets feature a retractable hose to allow for maximum use when washing those awkward-sized dishes.
If you’re set on sticking with your current style, buy another single-handle faucet.
The simplest type of faucet to install, a single-handle faucet works by positioning the knob to the left or right to make the water hot or cold or just push it straight up for a mild water temperature.
If you want to go hands-free, then buy a touch-less faucet. They work via a proximity sensor that detects if movement occurs in front of it, which, if detected, turns on the water.
Similar to many a shower faucet, a wall-mounted faucet is connected to the wall instead of the bathroom sink counter. Unlike a single handle faucet, these typically have two faucet valves to control the hot and cold water separately.

Inner-valve Types of Sink Faucets
There are so many brands, such as Delta, Moen, and Kohler, and types to choose from, that it can be hard to wrap your head around the differences. Here’s a quick breakdown of the inner mechanisms in faucets.
A ball faucet sometimes referred to as a washerless faucet, is a type of sink faucet that utilizes an inner-valve that relies upon a rotating plastic or metal ball for regulating water flow.
Due to the fact that they only rely upon one moving part to operate, they’re quite dependable. Considering buying a washerless faucet with a metal ball for even greater longevity.
A cartridge faucet relies upon an o-ring, located inside a cylindrical cartridge, to regulate the water flow. Due to their lack of moving parts, they’re quite reliable faucets.
Consider getting a brass cartridge faucet to ensure its durability.
Ceramic Disk Faucets
A ceramic disk faucet utilizes two ceramic discs, hence the name, that controls the water supply via the shearing action of the two discs.
They’re a great choice for a sink because they require almost no maintenance.
For many, their shower is a single handle faucet that they use to regulate the water supply of hot and cold water.
Sink faucets get used dozens of times a day in any given household, prevent any leak from happening by doing routine maintenance and replacing the faucet when it begins to show signs of irreparable wear.

Water Flow Controls (aka: Faucet Handle)
There are many types of faucet valves in use to control the water flow to a sink.
Materials Used for Bathroom Faucets
If you need to replace your sink, then take the time to learn the difference between the materials used and why it matters.
A common material used for sink faucets is brass, which is primarily an alloy of copper and zinc, although sometimes tin and aluminum are added into the mixture.
Brass faucets are easy to clean, highly durable, and have antimicrobial properties due to the copper. Although it costs more money, you’re paying for quality.
Brushed Nickel Faucets
Sometimes referred to as satin nickel, brushed nickel faucets are simple to clean and quite durable. Given their stylish appearance, they’re a popular choice for many.
Chrome is not just for those knockoff rims and spinners you see everywhere, you can also use it for your bathroom faucets at home.
Given its low cost and how easy it is to clean, chrome is a popular choice for many in a home. Although it’s not as durable as brass, the low cost makes up for it.
After all, who doesn’t like shiny objects?
Although technically they’re just copper finished, they still look nice. Given their atypical use in a bathroom, they’re bound to create the desired effect.
On the negative side, they do cost more money and don’t withstand the years as gracefully as other materials used for plumbing.
For many, a plastic faucet handle is a standard in their home. After all, they’re cheap to produce and withstand a great deal of daily wear, making them a reliable material to use.
If you want a simple and cheap option, plastic knob faucets have been around for decades and aren’t going anywhere anytime soon.
Stainless Steel Faucets
Another classic faucet material is stainless steel, given its durability and shiny texture, it’s used in a variety of products.
The only real drawback being its inclination to reveal water spots, luckily, all you need to do is use some bathroom cleaner to remove it.
If brass is too expensive for you, consider using a zinc faucet. Given its relative durability and resistance to corrosion, it’s a popular alternative. Although it’s a dull grey metal, you can easily buy one coated in chrome for a completely different look.
You can easily stay within budget and have a quality faucet with a new zinc handle or two.
