Bathroom Faucet Replacement in Bowmanville, Ontario

Choosing Bath Sink Faucets That Fit

A new faucet has to line up with the holes in your sink or vanity top, so count them before you shop. Bathroom faucets come in three main layouts:

• Single-hole faucets have the handle built into the faucet body and need just one hole.
• Centreset faucets, also sold as 4 inch spread or mini-spread faucets, use three closely spaced holes and keep everything compact.
• Widespread faucets, often sold as 8 inch spread faucets, have a separate spout and two handles on three holes set further apart. As a quick test, measure between the two handles: six inches or more calls for a widespread faucet, and less than six for a centreset model.

More Than One Hole to Cover

An old faucet's base plate can hide holes you cannot see from above, so look underneath with a flashlight, or let us measure when we quote. Changing from two handles to one is possible when the new faucet's base is wide enough to cover the unused holes: many cover holes 4 inches or less apart, and some single-handle faucets come with 8 inch plates for wider spacing.

How We Replace a Bathroom Faucet

1. 01Water to the basin is shut off at its two valves (at the main if they are stuck), and the faucet is opened to drain the lines.
2. 02The supply connections and mounting nuts come off and the old faucet is lifted out. Old putty, caulk or mineral buildup can hold a faucet to the sink, so it is cut free carefully to protect the vanity top.
3. 03With the faucet out, the valves and lines underneath get a close look. Valves that are seized, crusted or dripping are replaced, and so are tired supply lines.
4. 04The new faucet is mounted and sealed to the sink, connected to the water, and its drain assembly fitted or adjusted so the stopper opens and closes properly.
5. 05We run the water hot and cold, check each joint and the trap under the sink for leaks, and leave the vanity clean.

Bathroom Sink Fixtures Beyond the Faucet

Sometimes the faucet is not the only thing that needs to change. We also replace cracked or stained bathroom sinks, fit a new sink and faucet together when the vanity top changes, renew leaking drains and traps, and swap old shut-off valves for new ones. Elsewhere in the house we replace shower valves and trim, tub spouts, tubs and laundry tubs, and outside we install frost-free hose bibs. If the plan grows into moving the vanity or rebuilding the room, it becomes a job for our bathroom renovation service.

Permits, Water and Wells in Bowmanville

Swapping a faucet or sink in its current spot counts as replacing a fixture, and Clarington's Building Division, which sits at 40 Temperance Street in Bowmanville, does not normally require a permit for the replacement of plumbing fixtures. Moving the sink or adding a new one changes the plumbing and normally needs a permit, so call the Building Division at 905-623-3379 ext. 2660 before planning that kind of work.

In town, Bowmanville is on the Region of Durham's Lake Ontario water system, which has a supply plant in Bowmanville, and the Region lists the hardness of that system at 125 mg/L as calcium carbonate. The Region's private wells manual notes that hard water can leave scale on plumbing fixtures, and scale and grit tend to collect in the small screen of a faucet aerator, which is the first place to look when a bathroom faucet's flow weakens. On a private well in the hamlets north of town, reddish-brown marks on a new faucet are typically caused by iron, which the same manual says occurs naturally in groundwater. Water treatment, not another faucet, is the fix for that.

Bathroom Faucet Replacement Cost

Our 2026 Oshawa plumbing cost guide has no figure for faucets or sinks, so each Bowmanville job is priced on its own. The total depends on the faucet you choose, whether the shut-off valves and supply lines need replacing, and how easy the connections are to reach under the vanity. A faucet we supply appears as a separate item on the written quote, the quote is free, and we agree the price before work begins.
