Choosing between a freestanding tub filler and a deck-mount tub filler looks like a styling call, and partly it is. But the decision is really settled by plumbing: where your supply lines can run, what your tub is drilled for, and how much of the floor you are prepared to open up. This guide lays out the honest trade-offs so buyers anywhere in Canada, from Vancouver to Halifax, can get the choice right the first time.
What each type actually is
A freestanding tub filler, often called a floor-mount filler, rises from the finished floor on its own column beside the tub. Hot and cold supplies come up through the floor into the base, and the spout arches over the rim. Most models include an integrated mixing valve and a hand shower, which matters more than it sounds, because there is no other practical way to rinse out a freestanding tub.
A deck-mount tub filler installs through drilled holes, either in the rim of the tub itself or in a surrounding deck or ledge. The classic Roman tub set pairs a spout with two handles, and many sets add a hand shower on a fourth hole. The valve bodies hide below the deck, so the visible hardware stays low and tidy.
A wall-mount filler is a third path worth keeping in your back pocket. If your tub sits close to a wall, it delivers a similar over-the-rim look with simpler plumbing, since the supplies run inside the wall instead of under the floor.
The rough-in decides more than the style does
A floor-mount filler needs both supply lines brought up through the floor at an exact spot beside the tub, with solid blocking or a mounting plate anchored below the finished surface. If there is an open basement ceiling or an accessible joist bay underneath, this is routine work for a licensed plumber. If the bathroom sits on a concrete slab, which is common in condos and many newer builds across the country, the lines have to be trenched into the slab. That is realistic during a full renovation and painful as a standalone job.
A deck-mount filler needs somewhere to land: a tiled or stone deck built around the tub, or a tub rim wide and flat enough to accept faucet drillings. The plumbing runs below the deck, where it is easier to route and easier to reach later. If you are replacing a filler on an existing deck with holes already cut, deck-mount is by far the simpler project. Just measure the hole spacing and count the holes before you order.
Honest trade-offs, side by side
| Consideration | Freestanding (floor-mount) | Deck-mount |
|---|---|---|
| Best suited to | True freestanding tubs with no rim drillings | Drop-in, undermount and rim-drilled tubs, or any tub with a deck |
| Rough-in required | Supplies up through the floor at a precise location | Supplies routed below the deck or rim |
| Concrete slab floors | Slab must be trenched | Slab usually untouched |
| Servicing later | Valve lives in the column, access is limited | Valves reachable through the deck or an access panel |
| Visual effect | Sculptural, the filler becomes part of the room | Quiet, hardware stays low on the deck |
| Typical all-in cost | Higher, driven mostly by labour | Lower where a deck or drillings already exist |
Cost: the fixture is only half the story
In the Canadian market, floor-mount fillers generally sit above comparable deck-mount sets on price, since the column houses the valve, the riser and the finish work in one engineered piece. The bigger difference, though, is installation. Opening a floor, anchoring the mounting base, pressure-testing below the finished surface and closing everything back up takes real hours, and plumbers price it accordingly from St. John's to Victoria. A deck-mount set landing in existing holes can be a same-morning job. Budget for the whole path, not just the box.
Matching the filler to the tub
Start with the tub, not the tap. A true freestanding soaker with a rolled or narrow rim cannot take a deck-mount set, so if that silhouette is the dream, a floor-mount or wall-mount filler is the honest answer. Browse our freestanding bathtubs collection and check each model's drilling options before you commit, because some freestanding and back-to-wall tubs do offer factory rim drillings, which quietly reopens the deck-mount option.
Then check three numbers on the filler: spout height against your tub rim, spout reach so water lands well inside the basin rather than running down the inner wall, and flow rate, because large soakers fill slowly through an undersized spout. Household water pressure varies between provinces, municipalities and well systems, so treat published flow figures as best-case numbers.
Canadian buying notes
- Certification: look for cUPC or CSA marks, which indicate the fixture is certified for installation in Canada. Established brands carry them as a matter of course.
- Code: the National Plumbing Code sets the framework, but provinces and municipalities apply their own amendments. Your local inspector and licensed plumber have the final word, especially on valve access.
- Cold climate: keep supply runs out of exterior walls and unheated spaces below the floor. For a cottage or any seasonal property, from Muskoka to the Gulf Islands, make sure the filler's supplies can be isolated and drained for winter.
- Delivery: both styles ship readily Canada-wide; a floor-mount column is a longer, heavier parcel but nothing exotic.
Where the carried brands land
Canadian-designed lines are genuinely strong in this category. Riobel, Kalia and Aquabrass all offer freestanding and deck-mount fillers across modern and transitional styles, and Rubinet builds its fillers with unusually deep finish customization. Vogt covers contemporary European looks, while Kohler and Brizo bring broad family matching, so your tub filler, basin faucets and shower trim can share one design language. For traditional and heritage bathrooms, ROHL and Perrin & Rowe deck-mount sets with lever or cross handles remain the benchmark. You can compare all of these in our tub fillers collection.
A five-minute decision path
- Confirm what your tub accepts: rim drillings, a deck, or neither.
- Look below the floor. Open joists make floor-mount reasonable; a slab points to deck-mount or wall-mount.
- If a deck with holes already exists, measure the spacing and hole count, then shop deck-mount first.
- Check spout height, reach and flow against your specific tub.
- Have a licensed plumber confirm the rough-in and local code requirements before ordering.

Frequently asked questions
Can I use a deck-mount filler with a freestanding tub?
Only if the tub has a wide, flat rim with factory drillings, or the manufacturer explicitly allows drilling. Most true freestanding tubs do not, which is why floor-mount fillers exist. Check the tub's spec sheet before assuming either way.
Do freestanding tub fillers work on concrete slab floors?
Yes, but the supply lines must be trenched into the slab, so the work is best planned during a full renovation. If the tub can sit near a wall, a wall-mount filler achieves a similar look without touching the slab.
Are floor-mount tub fillers harder to service?
Somewhat. The valve sits inside the column and the connections are below the floor, so ask your plumber about accessible shutoffs during rough-in. Deck-mount valves are typically easier to reach through the deck or an access panel.
What certifications should a tub filler have in Canada?
Look for cUPC or CSA certification marks, which show the fixture has been tested to the standards Canadian plumbing codes reference. The established brands we carry meet this; it matters most when comparing unknown imports from marketplace sellers.
