What is the standard vanity height in Calgary bathrooms?

Standard builder-grade vanity height is 32 inches (81 cm) from floor to countertop — the historic standard set when most adults were shorter. Comfort height (also called ADA height) is 34–36 inches (86–91 cm), which is preferred by most adults today and required for accessible bathrooms under Alberta Building Code. If replacing a 32-inch vanity with a comfort-height unit, the supply line connections and drain rough-in are at the same height, so no plumbing changes are needed.

Do I need a plumber to replace a bathroom vanity in Calgary?

A like-for-like vanity swap — same supply line locations, same drain position — does not require a licensed plumber in Alberta. A handyman can shut off supply valves, disconnect the existing supply lines and P-trap, remove the old vanity, set the new one, reconnect supply lines and drain, and test for leaks. If the shut-off valves are seized (very common in Calgary due to hard water scale), the main water supply must be shut off to replace them — which is still handyman scope. If drain rerouting or new supply lines through walls are needed, that requires a plumber.

What causes bathroom shut-off valves to seize in Calgary?

Calgary's tap water is hard (170–200 mg/L calcium carbonate equivalent). Over years, calcium scale builds up on valve seats and stems. A shut-off valve that has not been operated in 10–15 years will often not close fully — or not close at all — when you try to turn it for a vanity swap. This is the most common complication in Calgary vanity replacements. The solution is to shut off the main water supply valve and replace the seized shut-off valves with new quarter-turn ball valves (which are more scale-resistant and easier to operate).

How much does bathroom vanity replacement cost in Calgary in 2026?

Labour for a like-for-like vanity swap (assuming working shut-off valves): $350–$500. If shut-off valves need replacement: add $85–$145. Vanity supply cost varies widely — IKEA Godmorgon series from $299, Home Depot Home Decorators Collection from $399, custom millwork from $1,200+. A complete bathroom vanity upgrade including new vanity, faucet, shut-off valves and labour typically runs $850–$1,500 depending on vanity choice.

What is the difference between freestanding, floating and built-in vanities?

Freestanding vanities rest on the floor with four legs or a solid base — easiest to install, easiest to clean around, but no storage under. Built-in (floor-mounted) vanities have a cabinet that sits on the floor — most common in Calgary homes, most storage, requires cutting the base for supply lines. Floating (wall-mounted) vanities attach to the wall with concealed brackets and have no floor contact — easiest to clean, requires blocking in the wall for the mounting hardware, and the drain must be stubbed out from the wall rather than the floor (requires a plumber if not already in place).

Vanity types: what to choose for a Calgary bathroom

Type	Description	Installation complexity	Calgary notes
Floor-mounted (built-in)	Cabinet sits on floor, integrated or drop-in sink	Standard — most common swap	Most Calgary homes have this; direct like-for-like swap
Freestanding / pedestal	Stand-alone unit or pedestal sink	Simple — no cabinet installation	No storage; pipes visible unless wrapped; common in older Calgary homes
Floating (wall-mounted)	Cabinet hangs from wall, no floor contact	Higher — requires wall blocking	Needs blocking in wall; drain must be wall-stub-out; modern look
Corner vanity	Fits into a 90° corner	Standard	Useful in small Calgary main-floor bathrooms

Vanity height: why the standard 32-inch is often wrong

Builder-grade vanities in Calgary homes built before 2010 are typically 32 inches tall (floor to countertop). This height was established decades ago and is considered too low for most modern adults — it requires bending over significantly for brushing teeth and washing hands.

Comfort height (34–36 inches) is now the standard for new vanity installation. It is also the height required for accessible bathrooms under the Alberta Building Code. When replacing a 32-inch vanity with a 36-inch unit:

The supply lines and shut-off valves are at the same height — no adjustment needed.
The P-trap and drain connection may need to be extended slightly upward — typically done with a P-trap extender, a standard plumbing fitting available at any hardware store.
The mirror or medicine cabinet above the vanity may need to be raised slightly.

The Calgary hard water shut-off valve problem

Calgary's tap water hardness of 170–200 mg/L (as calcium carbonate) is above the Health Canada guideline of 80 mg/L for water hardness. While safe to drink, hard water deposits mineral scale on every surface it contacts — including the seats, stems and packing of compression-type shut-off valves (the standard valve under most Calgary bathroom vanities built before 2010).

A shut-off valve that has not been operated in 10+ years often will not close fully when turned. This is the most common complication in Calgary vanity replacements — a job that would take 90 minutes in a newer home takes 3 hours because the shut-off valve needs to be replaced.

The fix: When the shut-off valve is seized, shut off the main water supply to the house (basement, near the meter), cut the supply line above the old valve, install a new quarter-turn ball valve (which resists scale far better than compression valves), and reconnect. New ball valves are operated at least once per year during annual home maintenance to prevent future seizing — a task covered in a standard home maintenance visit.

Installation steps: what actually happens during a vanity swap

Shut off supply valves. Test that both hot and cold supply shut-offs close fully. If either does not, plan to shut off the main and replace the valve before proceeding.
Disconnect supply lines. Use a bucket under each connection — supply lines hold residual water. Note: flexible braided supply lines are typically not reused — install new ones with the new faucet for reliability.
Disconnect the P-trap. The curved drain pipe under the sink. Have a bucket ready. Inspect the drain stub-out in the wall for condition — old lead or galvanized drain stubs in pre-1970 Calgary homes may need a plumber if corroded.
Remove the old vanity.Cut any caulk at the wall with a utility knife. Lift the top off if it's separate (drop-in sink style), then pull the cabinet out. Inspect the subfloor for moisture damage — soft spots near the drain mean water has been wicking under the base, possibly for years.
Patch and paint the wall where exposed. The new vanity is typically slightly different in footprint than the old one. The exposed wall area needs paint before the new cabinet is set.
Set and level the new vanity. Shim if the floor is not perfectly flat. Most bathroom floors in Calgary homes are slightly unlevel due to tile grout variation or subfloor sag.
Install faucet before setting countertop. It is dramatically easier to install a faucet with the sink accessible on sawhorses than to reach up inside the cabinet after installation.
Connect supply lines and P-trap. Use new flexible supply lines (12 or 16 inch depending on shut-off valve position). Do not overtighten — hand tight plus a quarter turn with adjustable pliers.
Turn supply on and test. Check both supply connections, the drain connection, and the P-trap for leaks. Run water for 3 full minutes and check again.
Caulk perimeter. Apply mould-resistant silicone at the countertop-to-wall joint and the vanity base-to-floor joint. Leave the rear base joint open on floor-mounted vanities — if a supply line ever fails, the water should flow out, not pool invisibly inside the cabinet.

What to buy before the installation visit

The vanity and any included countertop/sink. Confirm the width fits the existing space including side clearances.
The faucet. Confirm the number of holes (1-hole for single-handle, 3-hole for widespread) matches the sink.
A drain assembly. Usually included with the sink, but confirm — some vanities require a separate drain purchase.
Two flexible supply lines (12 or 16 inch, 3/8-inch compression fitting on valve end). Having these on hand avoids a hardware store run mid-job.
Mirror or medicine cabinet if replacing the old one at the same time.
