What is the difference between single and double handle faucets?

Single handle faucets use one lever to control both water flow and temperature by moving it up/down and left/right, while double handle faucets have separate controls for hot and cold water that you adjust independently to achieve your desired temperature and flow.

The main functional difference is in temperature control. With single handle faucets, you can quickly adjust to your preferred temperature with one motion once you learn the sweet spot. Double handle faucets require you to balance both valves, but they offer more precise control since you're directly managing the hot and cold water mix. Many people find single handles more convenient for quick tasks like washing hands, while others prefer the precise control of double handles for tasks requiring specific temperatures.

Installation and maintenance also differ significantly. Single handle faucets typically have more complex internal cartridges that can be more expensive to replace ($50-150 for parts), but you only have one mechanism to maintain. Double handle faucets have simpler individual valve stems that are usually cheaper to repair ($20-60 per side), but you have two potential failure points. In Ottawa's hard water areas, both types can develop mineral buildup, but double handle faucets often show wear more gradually since the load is split between two valves.

From a design perspective, single handles offer a cleaner, more modern look and work well in smaller spaces since they require less counter or wall space. Double handle faucets provide a more traditional or elegant appearance and are often preferred in heritage homes or classic bathroom designs. Both styles are available in similar price ranges, typically $150-800 for quality residential models.

For most Ottawa homeowners, single handle faucets are the practical choice for everyday use, while double handles work well when you want traditional styling or very precise temperature control for specific applications.
