Walk into almost any Canadian bathroom built in the last fifty years and you will find the same thing: a 60-inch alcove tub, a shower head above it, three walls of surround and a curtain rod. It is the most space-efficient layout ever devised, and the one builders treat as an afterthought. The footprint is not the problem. The best tub shower combo ideas keep the same alcove and upgrade what goes inside it, so this guide takes the decisions in the order you will make them: tub, shower side, enclosure, details.
Start with the tub, not the tile
The tub sets every other dimension, so choose it first.
- Alcove size. Measure stud to stud. Most alcoves are framed for a 60-inch tub, but older homes in Halifax or Winnipeg can surprise you. Confirm before ordering, because tubs ship by freight and returns are painful.
- Drain side. Alcove tubs come in left-hand and right-hand drain versions. Facing the alcove, the drain goes on the side your plumbing is on, unless you are moving it.
- Depth. Builder tubs are shallow. A deeper soaking alcove tub is the biggest comfort upgrade in the same footprint, and Kohler, Maax and American Standard all offer alcove models with a taller apron and a lower step-over.
- Material. Acrylic is light, warm to the touch and easy to install, which is why it dominates. Enamelled steel and cast iron feel more substantial and shrug off years of scrubbing, but they weigh far more. A cast iron tub from Cheviot or Kohler is a lifetime purchase; know your joists before it goes up the stairs.
If you want a bath that does more than hold water, air-jet alcove tubs from Bain Ultra are a Quebec-made option, though they need a dedicated circuit and an access panel. Browse our alcove and drop-in bathtubs to compare depths and drain configurations.
Upgrade the shower side, where builder basic falls apart
The usual complaint about combos is the shower, not the tub: a low fixed head, a flimsy spout diverter, and a valve that jumps when someone flushes downstairs. Three fixes change the whole experience.
- Choose the valve before the tile goes on. The rough-in lives inside the wall, so decide it early. Pressure-balance valves are the standard and guard against scalding when pressure changes. Thermostatic valves hold a set temperature regardless of flow and can run two outlets at full pressure, which matters if you want a hand shower and a rain head together. Riobel, Kalia and Aquabrass, all Quebec-based, make both types, as do Kohler and Brizo. Any valve should carry a CSA or cUPC listing. See our shower valves and rough-ins.
- Add a hand shower. On a combo this is not a luxury. It rinses the tub, washes kids and dogs, and works for anyone who needs to sit. On a slide bar it doubles as a fixed head at any height.
- Raise the head. Builder shower arms are mounted low. A longer arm, or a wall-mount rain head with a hand shower on a diverter, makes a standard alcove feel like a real shower. Pre-matched shower systems pair valve, trim and outlets in one finish without guesswork.
One honest trade-off: every extra outlet is another hole in the wall and another potential leak behind tile. A good valve, a rain head and a hand shower on a slide bar is plenty.
Doors versus curtains
A curtain is not a failure. In a kids' bathroom it is arguably the right call: cheap to replace, easy to pull aside, no track to clean. But if you want the combo to read as designed, glass is the biggest visual change you can make.
| Option | Best for | Trade-offs |
|---|---|---|
| Sliding bypass door | Full enclosure, keeps water in | Bottom track collects grime; only half the tub is open at a time |
| Fixed tub screen (single panel) | Open, modern look | Water can escape past the open end with a strong rain head |
| Hinged or pivot tub door | Frameless look, easy cleaning | Needs swing clearance; check tub deck width for the hinge |
| Curtain and rod | Kids' baths, rentals, tight budgets | Least durable; a curved rod adds elbow room |
Whatever you choose, match it to the tub deck. Some deep soakers have a narrow, rounded rim that will not take a door track or hinge plate, so confirm the tub and the shower door are compatible before either ships.
Details that make it look custom
- A tiled niche. Put it on the wall you cannot see from the hallway, and frame it in early.
- A matching drain and overflow. The chrome trip lever is the builder-era giveaway. Finish-matched trim from OS&B or Mountain Plumbing ties the tub to the faucetry. See tub drains and overflows.
- Grab bars that do not look clinical. Designer grab bars now match the trim finish and are worth adding for everyone, not just for aging in place. They need solid blocking behind the tile, so decide at framing.
- One finish family. Trim, door hardware, drain and grab bar in the same finish is what separates a considered bathroom from a collection of parts.
Canadian considerations before you order
- Certification. Valves, tubs and doors installed in Canada should be CSA or cUPC listed. Reputable brands are; grey-market imports often are not, and an inspector can fail the job over it.
- Code and permits. The National Plumbing Code is the model, but each province and territory adopts its own version, and Quebec's construction code has its own plumbing chapter. A same-spot tub swap is usually simple; moving the drain or valve, or adding a circuit for an air-jet tub, typically needs a permit. Check with your municipality.
- Cold climate. If the tub sits against an exterior wall, insulate behind and beneath it. Supply lines in an uninsulated exterior wall are a January problem in the Prairies and northern Ontario. Deeper tubs also draw more hot water, and incoming water is coldest in winter, so check that your water heater can keep up.
- Freight and pricing. Tubs ship by pallet anywhere in Canada, from Vancouver Island to St. John's. Confirm the address can take a truck and inspect before signing. Everything here is priced in Canadian dollars, with no exchange-rate or border surprises.

Frequently asked questions
Can I replace just the tub and keep the existing surround?
Rarely cleanly. The surround overlaps the tub's tile flange, so pulling the tub usually damages the bottom course of tile or the edge of an acrylic panel. Budget to replace the lowest row at minimum, and expect a one-piece acrylic surround to come out with the tub.
Is a thermostatic valve worth it on a tub-shower combo?
If you only run a single head, a quality pressure-balance valve is fine and simpler. Thermostatic makes sense when you want two outlets at once, fill the tub often and want the same temperature every time, or have small children or older adults using the bath.
Do I need a permit to upgrade a tub-shower combo?
A like-for-like swap in the same location usually does not, but moving drains, relocating the valve, adding electrical for an air-jet tub or changing wall structure typically does. Rules vary by province and municipality, so call your local building department before demolition.
What is the best door for a tub-shower combo?
For most households, a frameless sliding bypass door balances water control, cleaning and looks. A fixed single screen suits an open feel when the shower head is not a strong rain head. Either way, confirm the tub deck is flat and wide enough for the track or hinge plate before ordering both.
