Most people plan a shower renovation around the tile, the glass and the shower system, then pick a drain at the last minute. That order is backwards. The drain decides how the floor is sloped, how the waterproofing is detailed and, in a curbless design, whether the whole concept works at all. Choosing well comes down to four questions, answered in the right order. Work through them and the options narrow themselves, whether you are renovating a condo in Vancouver, a century home in Halifax or a bungalow in Winnipeg.
Answer the questions in this order
Each question eliminates more options than the one after it:
- Space: what does the room and rough-in allow?
- Users: who showers here, and what do they need?
- Budget tier: where should the money actually go?
- Style: which finish and grate tie the room together?
Style comes last on purpose. A beautiful grate on the wrong drain body is an expensive mistake; the reverse is a quick swap.
Question 1: what does your space allow?
Start with the two big categories. A point drain, usually round or square and set near the centre of the floor, collects water from four small slopes. A linear drain is a long channel, typically placed against a wall or across the entrance, that lets the whole floor slope in a single plane. Your installation type narrows this immediately:
- Preformed shower base: the drain location, outlet size and connection style are already decided by the base. Check the specification sheet for your shower base first, then buy a drain assembly that matches it exactly.
- Tiled shower floor: both types are on the table. Linear drains pair especially well with large-format tile, since the floor can slope in one direction without diagonal cuts.
- Curbless or barrier-free shower: a linear drain at the entrance or along the back wall is usually the cleanest way to control water without a curb.
Then look down, not around. Moving a drain a few centimetres in a wood-framed floor is a manageable job. Moving one in a concrete condo slab in Toronto or Montreal can involve coring, building approvals and real money. If relocating the pipe is off the table, your drain choice has to come to the pipe.
Finally, confirm the connection itself. Most modern Canadian showers connect to a 2 inch outlet, but older homes and tub-to-shower conversions can differ. The National Plumbing Code sets the baseline and each province applies its own version, so let your plumber have the final word on sizing, venting and traps.
Question 2: who uses this shower?
The drain should reflect your household, not a generic one:
- Aging in place or accessibility needs: a curbless entry with a linear drain removes the threshold entirely and works with wheeled shower chairs. If this is even a maybe in the next decade, planning for it now is far cheaper than retrofitting later.
- Long hair in the household: look for a removable strainer or hair basket you can lift out without tools. This one feature prevents most clogged-drain service calls.
- A seasonal or rural property: cottages that sit empty through a Prairie or Quebec winter get winterized, and a drain with an accessible trap and serviceable parts is much easier to live with than a sealed assembly buried under tile.
- A high-flow shower: multi-outlet shower systems with body jets and rain heads move a lot of water at once. Make sure the drain is rated to keep up, or you will be standing in a puddle no matter how good the tile work is.
Question 3: which budget tier makes sense?
Shopping in Canadian dollars, you will generally find three tiers:
| Tier | What you typically get | Best fit |
|---|---|---|
| Entry | Point drains with plastic bodies and standard metal grates | Preformed bases, rental units, straightforward replacements |
| Mid-range | Stainless steel construction, proper membrane clamping, removable hair strainers | Tiled floors, family bathrooms, most renovations |
| Premium | Designer linear channels, tileable grate inserts, specialty finishes, height-adjustable frames | Curbless designs, large-format tile, statement bathrooms |
One honest note: the drain is rarely the expensive part of a shower floor. Waterproofing and labour cost far more, and a failed membrane connection costs more still. If you need to economize, the drain body and its clamping mechanism are the wrong place; the decorative grate is a fine one.
Question 4: what style ties the room together?
Only now does appearance enter the picture, and by this point you are choosing between a handful of qualified options rather than hundreds. Match the finish to your other fittings: brushed stainless and chrome are the safe defaults, while matte black and brushed gold make the drain a deliberate accent. Grate patterns range from classic slots and wave designs to minimal frames, and a tileable insert lets you set a piece of your floor tile into the grate so only a thin outline shows. Order the drain alongside your tile decisions, not after them, so colour and proportions are confirmed before waterproofing begins.
Red flags in a drain listing
When comparing products online, a few omissions should make you pause:
- No certification information. Plumbing fittings sold for Canadian installations should carry recognized marks such as cUPC or CSA. A listing that says nothing about certification is a listing to question.
- No outlet size or connection type. If you cannot tell how the drain connects to the pipe, you cannot know it fits your rough-in.
- Vague materials. Good listings name the body material and the stainless grade, not just a metal grate.
- No waterproofing details on a tile-in drain. Drains for tiled floors need a clear answer on how they clamp or bond to the membrane.
- Universal fit claims. Shower bases vary. A drain that claims to fit everything deserves a close read of the fine print.
Your final checklist
Before you commit, confirm every line:
- Drain type matches the installation: base, tile-in point, or linear.
- Outlet size and connection match your rough-in, verified with your plumber.
- Certification marks suit a Canadian installation.
- Flow capacity suits your shower system.
- The strainer is removable for cleaning.
- The finish is confirmed against your tile and fittings, not guessed from a screen.
- Local code questions are settled before anything is ordered.

Frequently asked questions
Are linear drains harder to install than centre drains?
Somewhat, but not dramatically so for an experienced installer. A linear drain needs a single-plane slope and careful waterproofing along its length; a point drain needs four slopes meeting in the middle. The bigger risk with either is a rushed membrane connection, so the installer matters more than the drain style.
What size is a standard shower drain in Canada?
Most modern shower installations connect to a 2 inch outlet, and shower bases are typically built around that assumption. Older homes and converted tub spaces can differ, and provincial plumbing codes govern the details, so have your plumber confirm the rough-in before you order.
Do I need a special drain for a curbless shower?
Not a special category, but a deliberate choice. Curbless designs almost always work best with a linear drain at the entrance or back wall, because the entire floor can slope gently in one direction. The waterproofing plan matters even more than usual since there is no curb holding water back.
Can I change the look of a drain without replacing it?
Often, yes. Many drains offer replacement grates in different patterns and finishes that fit the same body. If a future refresh matters, choose a line with multiple grate options and confirm the grate is sold separately.
