This comes down to a genuinely simple trade-off once you strip away the styling debate: one handle controlling both temperature and flow, or two handles giving you separate control over hot and cold. Both work well. They just suit different priorities — speed and simplicity on one side, precise temperature control and a more traditional look on the other.
What is a single-handle faucet?
One lever controls both water flow and temperature by mixing hot and cold internally as you move the handle side to side and up and down. It's the more common style in modern bathrooms and kitchens, largely because it's fast to use and simple to install.
Most single-handle faucets use a single-hole installation, meaning your sink or countertop only needs one cutout. Internally, they typically rely on a ceramic disc cartridge, which is durable and resists the mineral buildup that can affect older washer-based designs.
Pros of single-handle faucets
- Operable with one hand, which matters for anyone dealing with messy hands, limited dexterity, or just wanting speed
- Fewer surfaces to clean, since there's only one handle rather than two plus the spout
- Simpler, cheaper installation thanks to the single-hole design
- Fits well with modern, minimal bathroom and kitchen styling
Cons of single-handle faucets
- Fine temperature adjustment can take a moment to dial in, since one lever is doing two jobs at once
- If the internal cartridge fails, it typically takes the whole faucet's function down with it, since everything routes through that one mechanism
- Fewer traditional style options compared to the range available in double-handle designs
What is a double-handle faucet?
Two separate handles, one for hot water and one for cold, each controlling its own valve. You mix the temperature by adjusting both independently rather than relying on one combined mechanism.
Double-handle faucets typically require a three-hole installation — one for each handle and one for the spout — which is worth checking against your existing sink or countertop before committing to this style, especially if you're replacing a single-handle faucet and would need to modify the countertop to fit three holes.
Pros of double-handle faucets
- More precise, independent control over hot and cold water temperature
- Classic, traditional aesthetic that suits period-style or transitional bathroom designs
- If one valve develops an issue, the other side often continues working independently, rather than losing water access entirely
- Wider range of design styles available, from ornate traditional to clean transitional looks
Cons of double-handle faucets
- Requires more counter or sink space for the three-hole configuration
- More expensive and involved installation, particularly if your sink isn't already drilled for three holes
- Slower to adjust with two hands, especially in a busy kitchen where quick temperature changes matter
- Two separate valve mechanisms mean more parts that can eventually need maintenance
Single-handle vs. double-handle: side-by-side
| Factor | Single-Handle | Double-Handle |
|---|---|---|
| Installation holes needed | 1 | 3 |
| Temperature control | Fast, less precise | Slower, more precise |
| Typical cartridge type | Single ceramic disc cartridge | Two independent valve cartridges |
| Style | Modern, minimal | Traditional, classic |
| Space needed | Less | More |
| Installation cost | Generally lower | Generally higher |
Which one should you choose?
Ease of use
If speed and one-handed operation matter most, single-handle is the clear choice. If precise, independent temperature control matters more than convenience, double-handle wins here.
Available space
Smaller sinks or tight countertop space favor single-handle, since it only needs one hole and takes up less visual and physical room. A larger sink or vanity has the space to accommodate a double-handle setup comfortably.
Aesthetic preference
Modern and minimalist bathrooms generally lean single-handle. Traditional or classic interiors tend to suit the look of a double-handle faucet better.
Installation requirements
Single-handle is simpler and cheaper to install, particularly relevant if you're not already working with a pre-drilled three-hole sink. Double-handle makes more sense if you're doing a full renovation where hole configuration isn't a constraint.
Durability and maintenance
Single-handle faucets have fewer parts overall, which simplifies maintenance, but that single mechanism handles more workload since it's doing both jobs at once. Double-handle faucets split the workload across two valves, which can mean more individual parts to maintain but less strain on any single mechanism.
Other factors worth considering
Material and finish
- Brass: Highly durable and corrosion-resistant, a common choice for the internal faucet body regardless of handle style
- Stainless steel: Resists rust and maintains a polished look without frequent upkeep
- Chrome: Reflective and classic, though it shows fingerprints and water spots more readily than matte finishes
- Matte black: A popular modern choice that hides fingerprints and water spots better than polished finishes
Water efficiency features
- Aerated faucets: Mix air into the water stream to maintain a sense of pressure while using less water
- Low-flow designs: Reduce overall water consumption, often paired with WaterSense certification
- Touchless faucets: Use motion sensors to limit water flow to only when hands are actually present
Smart features to consider
- Touch-activated faucets: Turn water on or off with a light tap anywhere on the faucet body
- LED temperature indicators: Visual color cues that show water temperature before contact
- Bluetooth and voice control: Integration with broader smart home systems, available on select premium models
Final thoughts
Neither style is objectively better — single-handle wins on convenience and simple installation, double-handle wins on precise control and traditional styling. Match the choice to your available space, existing hole configuration, and how much you value speed versus fine temperature control day to day.

Frequently asked questions
Q1. Which is easier to install, single-handle or double-handle?
Single-handle is generally easier and cheaper to install, since it only requires a single-hole configuration. Double-handle faucets typically need three holes, which can require additional countertop or sink modification if you're switching from a single-handle setup.
Q2. Which type lasts longer?
Both can last many years with proper care. Single-handle faucets have fewer total parts, but that one mechanism handles the full workload. Double-handle faucets split the work across two valves, which distributes wear differently rather than making one style definitively more durable than the other.
Q3. Can I switch from a double-handle to a single-handle faucet?
Yes, but it typically means covering the extra holes left in a three-hole sink or countertop, either with a deck plate or by choosing a single-handle model designed to cover a three-hole configuration.
Q4. Which style gives better temperature control?
Double-handle faucets generally offer more precise, independent control over hot and cold, since each is adjusted separately. Single-handle faucets are faster to use but require a bit more finesse to dial in an exact temperature.
Q5. Are single-handle faucets more prone to breaking?
Not inherently — modern single-handle faucets typically use a durable ceramic disc cartridge. If that cartridge does fail, however, it affects the entire faucet's function since both flow and temperature route through the same mechanism.
Q6. What's the difference in cost between the two styles?
Single-handle faucets are generally less expensive to purchase and install due to the simpler single-hole configuration. Double-handle faucets often cost more both for the fixture itself and for installation, particularly if hole modification is required.
