Best Toilets for Montreal Homes: One-Piece, Two-Piece & Wall-Mount Compared
⚡ Quick Answer
The best toilets for Montreal homes depend on your bathroom size, budget, and preferences. Two-piece toilets ($100 – $500) are the most affordable and easiest to repair. One-piece toilets ($250 – $1,200) offer a sleeker look and easier cleaning. Wall-mount toilets ($400 – $2,000+) save floor space and look ultra-modern but cost the most to install. For most Montreal families, a one-piece comfort-height toilet with dual flush is the sweet spot for value, efficiency, and comfort.

Shopping for a new toilet in Montreal? If you haven’t bought one in a decade, you’ll be surprised by how much has changed. Today’s best toilets for Montreal homes use half the water of older models, flush more powerfully, and come in styles that range from budget-basic to high-tech smart units with heated seats and bidet functions.

Do you need a one-piece or two-piece? Is a wall-mount toilet worth the extra cost? What flush technology actually matters?
This buyer’s guide compares every toilet type side-by-side — with real pricing, installation costs, pros and cons, and what Montreal plumbers actually recommend based on years of installing them. By the end, you’ll know exactly which toilet to buy and what to budget for toilet and installation combined.
Toilet Types at a Glance: The Complete Comparison
Two-Piece Toilets: The Budget-Friendly Classic
✅ Pros
→ Most affordable option ($100 – $500)
→ Lighter pieces make installation easier
→ Individual tank/bowl can be replaced separately
→ Replacement parts widely available at any hardware store
→ Widest variety of styles and sizes
❌ Cons
→ Seam between tank and bowl collects grime
→ Harder to clean around the base and joint
→ Slightly more prone to leaks at the tank-to-bowl connection
→ Can look dated in a modern bathroom
Best two-piece models for Montreal: The TOTO Drake ($250 – $400) is the go-to recommendation from plumbers across Canada thanks to its powerful Tornado Flush and excellent clog resistance. The American Standard Cadet 3 ($150 – $280) is a reliable budget choice with solid flush performance. And the Kohler Wellworth ($200 – $350) offers a Class Five flush system that handles heavy use well.
Total installed cost: For a standard two-piece toilet and installation, budget $280 – $850 in Montreal.
One-Piece Toilets: The Modern All-Rounder
✅ Pros
→ Seamless design — no tank-to-bowl joint
→ Much easier to clean (no crevices)
→ Sleeker, modern appearance
→ Lower profile fits well in smaller bathrooms
→ More durable — fewer exposed internal parts
❌ Cons
→ Heavier (60 – 100+ lbs), requires two people to lift
→ More expensive than two-piece ($250 – $1,200)
→ If either section cracks, entire unit must be replaced
→ Some internal parts are harder to access for repair
Best one-piece models for Montreal: The TOTO Ultramax II ($400 – $600) is a perennial plumber favourite — CeFiONtect glaze keeps the bowl cleaner and its Tornado Flush is outstanding. The Kohler Santa Rosa ($350 – $550) is a compact design ideal for smaller Montreal bathrooms. And the American Standard Boulevard ($300 – $500) delivers a clean skirted look at a mid-range price.
Total installed cost: Budget $450 – $1,600 for a one-piece toilet purchase and installation in Montreal.
💡 Plumber’s Pick: Most Montreal plumbers we work with recommend one-piece toilets with a skirted base and comfort height as the best overall choice. The skirted base (smooth sides instead of visible trapway curves) makes cleaning dramatically easier, and comfort height (17 – 19 inches) is easier on knees for adults while still fine for children.
Wall-Mount Toilets: The Premium Space-Saver
✅ Pros
→ Saves 10 – 12 inches of floor space
→ Easiest to clean — nothing touches the floor
→ Modern, high-end appearance
→ Adjustable seat height during installation
→ Concealed tank = quieter flush
❌ Cons
→ Highest wall mounted toilet installation cost ($500 – $1,200 labour)
→ Requires in-wall steel carrier frame
→ Wall must be opened for installation and repairs
→ Tank repairs require access panel or wall demolition
→ Not suitable for all Montreal condos or older homes
Best wall-mount models for Montreal: The Duravit Starck 3 ($500 – $1,000) is a designer favourite paired with a Geberit carrier frame. The Swiss Madison Ivy ($200 – $400) delivers the wall-mount look at a budget-friendly price. And the TOTO Aquia Wall-Hung ($600 – $1,200) combines dual-flush efficiency with TOTO’s legendary flush performance.
Total installed cost: Including the carrier frame, bowl, actuator plate, and professional installation, a wall mounted toilet installation cost in Montreal runs $900 – $3,200.
⚠️ Important: Wall-mount toilets require a reinforced wall capable of supporting 200+ kg of weight. In older Montreal homes with plaster-and-lath walls, this may mean significant additional framing work. Always have a licensed plumber assess your wall before purchasing a wall-mount model.
Smart Toilets & Bidet Seats: The Comfort Upgrade
Smart toilets are the fastest-growing segment in bathroom plumbing — and for good reason. Features that were once reserved for high-end Japanese bathrooms are now available at Canadian price points. Here’s what you get:
Common Smart Toilet Features
✅ Integrated bidet wash
✅ Heated seat
✅ Warm air dryer
✅ Auto-open / auto-close lid
✅ Touchless flush
✅ Deodoriser
✅ LED night light
✅ Self-cleaning nozzle
Best smart toilet options: The TOTO Washlet+ ($600 – $2,000) is the gold standard in bidet seats that fit on your existing toilet. A full TOTO Neorest ($3,000 – $6,000+) is the ultimate integrated smart toilet. The Kohler Veil Intelligent ($2,500 – $4,000) offers sleek design with full automation. For a budget entry, the Bio Bidet BLISS BB2000 ($400 – $600) bidet seat adds smart features to any existing toilet without replacing the unit.
Installation note: Smart toilets and bidet seats require a GFCI electrical outlet within 1 metre of the toilet. If your Montreal bathroom doesn’t have one, an electrician will need to install it first ($150 – $350). Your plumber can coordinate this during the same visit.

What Montreal Plumbers Actually Recommend (Brand Rankings)
After installing thousands of toilets across Montreal, here are the brands our plumbing team recommends — and the ones we suggest avoiding:
According to Consumer Reports’ 2026 toilet testing, WaterSense-certified models from TOTO, Kohler, and Glacier Bay consistently outperform in flush efficiency and bowl cleanliness. All models listed above are readily available at Montreal retailers including Home Depot, Réno-Dépôt, and local plumbing supply houses.
Toilet Buying Checklist: 8 Things to Measure Before You Shop
Before visiting the store or ordering online, grab a tape measure and check these critical dimensions:
Rough-in distance: Measure from the finished wall (not the baseboard) to the centre of the toilet drain bolts. Standard is 12 inches — but older Montreal homes may have 10-inch or 14-inch rough-ins.
Available width: Ensure at least 15 inches of clearance from the toilet centre to each side wall or vanity. Building code requires a minimum of 15 inches.
Front clearance: You need at least 21 inches from the front of the bowl to any wall or fixture for comfortable use.
Bowl shape: Elongated bowls (18.5 inches) are more comfortable but need more space. Round bowls (16.5 inches) fit tighter bathrooms.
Seat height: Standard is 15 inches; comfort height is 17 – 19 inches. Taller toilets are easier for adults and seniors but may be too high for young children.
Water supply location: Most toilets connect on the left side. If yours is on the right, confirm the model you’re buying accommodates that.
Flush technology: Look for WaterSense certification (4.8 LPF or less in Canada). Dual-flush models save the most water.
Electrical outlet (if smart toilet): Check if a GFCI outlet exists within 1 metre of the toilet location. If not, factor in electrician costs.
Not sure about your measurements? Your plumber can confirm all dimensions during an in-home assessment before you purchase — saving you from buying the wrong toilet.
Water Efficiency: How Canadian Flush Standards Work
In Canada, the WaterSense program by Natural Resources Canada certifies toilets that use 4.8 litres per flush (LPF) or less — 20% less than the national maximum of 6 LPF. All models recommended in this guide meet or exceed WaterSense standards.
If you’re replacing an older toilet (pre-1996 models used up to 13 LPF), upgrading to a modern dual-flush toilet can save a family of four roughly 50,000 – 65,000 litres of water per year — translating to $150 – $200 in annual water bill savings. Some Quebec municipalities also offer rebates for installing WaterSense-certified toilets.
Why Professional Installation Matters
Even the best toilet won’t perform well if it’s improperly installed. Here’s why hiring a licensed Montreal plumber for your toilet purchase and installation is worth every dollar:
🔧 Proper seal: A poorly seated wax ring causes slow leaks that rot subfloors — the most expensive hidden damage in bathrooms. Plumbers know the exact pressure to apply.
🔧 Level placement: An uneven toilet rocks, breaks wax seals, and cracks porcelain over time. Plumbers shim and level precisely before bolting down.
🔧 Flange inspection: Every toilet replacement is an opportunity to inspect the flange and drain. Catching corrosion or cracks now prevents emergency leak repairs later.
🔧 Wall-mount expertise: Installing an in-wall carrier frame requires structural knowledge, precise drain alignment, and drywall finishing. This is never a DIY job.
🔧 Code compliance & warranty: CMMTQ-licensed installation ensures Quebec plumbing code compliance and protects your manufacturer warranty. Especially important for bathroom renovations where inspection may be required.
Frequently Asked Questions: Buying & Installing a Toilet in Montreal
Is a one-piece or two-piece toilet better?
For most Montreal homeowners, a one-piece toilet is the better choice. It’s easier to clean, has a sleeker appearance, and is more durable since there’s no tank-to-bowl joint that can leak. However, two-piece toilets are significantly cheaper and easier to repair, making them ideal for budget installations or rental properties.
How much does wall-mounted toilet installation cost in Montreal?
A wall-mounted toilet installation in Montreal costs $900 – $3,200 total, including the toilet bowl ($400 – $2,000), in-wall carrier frame ($200 – $500), actuator plate ($50 – $300), and professional labour ($500 – $1,200). The labour is higher because the plumber must open the wall, install the frame, connect plumbing, and finish with drywall.
What toilet brand do plumbers recommend most?
TOTO and American Standard are the two brands most consistently recommended by Montreal plumbers. TOTO is praised for its superior flush technology and glazing, while American Standard offers excellent reliability at lower price points. Both brands have strong parts availability in Canada and are CSA-certified.
What is comfort height and should I choose it?
Comfort height toilets sit at 17 – 19 inches from floor to seat, compared to 15 inches for standard height. They’re easier to sit on and stand up from, especially for taller adults and seniors. Most plumbers recommend comfort height for primary bathrooms. Standard height may be better for kids’ bathrooms.
Can I add a bidet seat to my existing toilet?
Yes. Bidet seats are designed to replace your existing toilet seat on most standard elongated bowls. You’ll need a GFCI electrical outlet within reach. A plumber can install both the bidet seat and the outlet during a single visit, typically for $200 – $400 in labour plus the cost of the seat itself.
How much does toilet purchase and installation cost together?
Total cost for toilet and installation in Montreal ranges from $280 to $850 for a two-piece, $450 to $1,600 for a one-piece, $900 to $3,200 for a wall-mount, and $750 to $5,500+ for a smart toilet. These prices include the fixture, labour, old toilet removal, and basic materials like the wax ring and supply line.
What is a skirted toilet and is it worth it?
A skirted toilet has smooth, flat sides that conceal the trapway (the S-shaped pipe at the base). This makes cleaning much easier since there are no curves or grooves to scrub around. Skirted models cost $50 – $150 more than exposed-base versions and may require special mounting hardware, but most homeowners find the easier cleaning well worth it.
Do I need to measure my rough-in before buying a toilet?
Absolutely. The rough-in distance (from finished wall to drain centre) determines which toilets will physically fit in your bathroom. Most Montreal homes use a 12-inch rough-in, but older homes may have 10 or 14 inches. Buying the wrong rough-in means the toilet either won’t fit or will sit too far from the wall.
Are dual-flush toilets worth it in Montreal?
Yes. Dual-flush toilets let you choose between a light flush (3.0 LPF) for liquid waste and a full flush (4.8 LPF) for solid waste. For a family of four, this can save 50,000+ litres of water per year compared to an older model, reducing your annual water bill by $150 – $200. The investment typically pays for itself within 2 – 3 years.
How long does a toilet last before it needs replacing?
A well-maintained toilet can last 15 to 25 years or more. However, internal components such as flappers, fill valves, and flush handles typically need replacing every 5 – 10 years. Signs that a full replacement is needed include frequent clogging, visible cracks, constant running, rocking, or using more than 6 LPF.
