How do I choose between a single-handle and a widespread bathroom faucet?

Choose a single-handle faucet for practicality, ease of use, and simpler installation, or a widespread faucet for a more traditional, upscale look and precise temperature control. The right choice depends on your vanity configuration, bathroom style, budget, and how you use your bathroom daily.

Single-handle faucets use one lever or knob to control both water flow and temperature by moving the handle up and down for volume and left to right for temperature. They are the most popular choice in Calgary bathroom renovations for several practical reasons. Installation is simpler because you only need one faucet hole in the countertop or vanity top, which means virtually any vanity or countertop configuration works. They are easier to operate with wet, soapy hands — a real advantage during daily use. Single-handle faucets are also typically more affordable, ranging from $80 to $400 in Calgary depending on brand and finish. From a maintenance perspective, there is only one cartridge to replace if the faucet develops a drip, and replacement cartridges for major brands like Moen, Delta, and Kohler are readily available at Calgary plumbing suppliers for $15 to $40.

Widespread faucets (also called 8-inch spread faucets) have three separate components — two handles and a spout — each mounted independently with 6 to 16 inches between the outer handles. They provide precise, independent control of hot and cold water, which some homeowners prefer for dialling in an exact temperature. The visual impact is more substantial and traditional, making widespread faucets a natural fit for larger vanities (36 inches and wider), double vanities, and bathrooms with classic or transitional design styles. Widespread faucets range from $150 to $600 in Calgary and require a vanity top or countertop with three pre-drilled holes spaced to match the faucet's spread.

There is a third option worth considering — the centerset faucet, which combines two handles and a spout on a single base plate, typically fitting a standard three-hole configuration with 4-inch centres. Centresets offer the traditional two-handle look in a more compact package and are ideal for smaller vanities where a widespread layout would look crowded.

For Calgary's hard water specifically, single-handle faucets have a slight practical advantage because there are fewer components and crevices where mineral deposits accumulate. With a widespread faucet, hard water deposits can build up around each of the three mounting points and in the connections beneath the countertop. Whichever style you choose, opt for brushed nickel or matte black finishes to minimize visible hard water staining — polished chrome shows Calgary's mineral deposits almost immediately.

Your vanity dictates some of this decision. If you are ordering a new vanity with a pre-drilled countertop, confirm the hole configuration before purchasing your faucet. Many quartz and granite countertop fabricators in Calgary can drill custom hole configurations, giving you flexibility — but this needs to be specified at the time of ordering, not after fabrication. If you are keeping your existing vanity and simply upgrading the faucet, match the new faucet to the existing hole pattern to avoid drilling or filling holes.

Installation cost is similar for both styles — $100 to $200 for professional installation by a plumber, which includes connecting supply lines and testing for leaks. This is one bathroom upgrade that a handy homeowner can tackle as a DIY project if you are comfortable working under a vanity with basic plumbing connections, though hiring a professional ensures leak-free connections and proper sealing.
