The walk-in shower has become the default request in almost every bathroom renovation we quote, and for good reason. It reads as more spacious than a tub-shower combo, it is easier to clean, and it works for a household at every stage of life without looking institutional. It is also one of the easier renovations to get subtly wrong.
A walk-in shower renovation in Vancouver involves more decisions than the finished photos suggest — drain placement, glass configuration, curb height, and waterproofing all interact with each other in ways that are hard to undo once tile is set. This guide walks through what actually needs deciding before demolition starts.
Curbless or Curbed: The First Decision That Shapes Everything Else
A curbless — or zero-threshold — shower removes the small dam most people are used to stepping over. It reads as more open and works better for anyone with mobility concerns, now or down the road, which is why it has become the more requested option among Vancouver homeowners planning a renovation they intend to stay in long-term.
The trade-off is structural. A curbless shower needs the floor to slope toward the drain across the entire wet area, not just inside a contained pan, and that slope has to start further back if there is no curb to contain the water. On a main floor over a concrete slab this is usually straightforward. On an upper floor over a wood-framed subfloor, it can mean recessing the joists or building up the surrounding floor to create the slope without a step, which adds cost and sometimes isn’t possible without opening the ceiling below.
A curbed shower remains the simpler build in most cases, particularly on upper floors, and a low curb — around 2 inches rather than the traditional 4 — captures much of the open feeling without the structural complexity.
Drain Type: Point Drain Versus Linear Drain
Point drains sit in the center or a corner of the shower floor, and the floor slopes toward that single point from all directions. They are the more affordable option and work fine for smaller or squarer shower footprints.
Linear drains run along one edge of the shower, usually against a wall, and the floor only needs to slope in one direction rather than from every corner toward a center point. This makes them a natural fit for curbless showers and for longer, narrower shower footprints where a single point drain would create an awkward multi-directional slope. They also tend to read as more contemporary, which is part of why they show up in most current renderings.
Homeowners across the Lower Mainland comparing quotes should confirm which drain type is priced in — a linear drain and the tile cuts it requires typically add several hundred dollars over a standard point drain, and that difference is not always broken out clearly in a lump-sum estimate.
Glass Configuration and What It Actually Costs
Frameless glass has become close to standard for walk-in showers, and for good reason — it disappears visually in a way framed enclosures never do. But “frameless” covers a range of configurations with very different price points.
A single fixed panel is the most affordable frameless option and works well when the shower opening is naturally protected from spray by the room layout. A panel plus a door costs more but is often necessary for larger openings. Fully enclosed frameless systems with multiple panels and a door cost the most and make sense mainly for showers positioned where spray control matters in every direction.
Glass thickness matters more than most homeowners realize going in. 3/8-inch glass is the common standard; 1/2-inch glass costs more but feels noticeably more substantial and requires less hardware to stay rigid, which is part of why higher-end installations tend to specify it.
Waterproofing Behind the Walls
None of the visible decisions matter much if the waterproofing behind them fails. Every walk-in shower needs a continuous waterproof membrane across the floor and up the walls to a minimum height, with particular attention at seams, the drain connection, and any niche cut into a wet wall.
This is where corners get cut on lower-end quotes, because it is invisible once tile goes up and the failure often doesn’t show for a year or more — by which point the fix means demolishing the shower. Schluter’s KERDI membrane system is what we specify on nearly every walk-in shower we build, because it is a fully bonded, sheet-applied system rather than a liquid-applied coating that depends heavily on application technique.
Homeowners in Burnaby, where older housing stock is common, should ask specifically whether the quote includes removing the shower down to the studs or whether it is tiling over an existing pan — the latter is sometimes offered as a shortcut and it defeats the purpose of a proper waterproofing rebuild.
The same question is worth asking regardless of city. Older bathrooms in Delta carry the same risk of a shortcut re-tile hiding a compromised membrane underneath, and the only way to know for certain is to ask what the scope of demolition actually includes.
Minimum Sizing and Realistic Layouts
A walk-in shower needs real space to feel like the upgrade it is meant to be. Most codes and comfortable design practice put the functional minimum around 36 by 36 inches, though 42 by 42 inches or larger reads noticeably more spacious and gives more flexibility for fixture placement.
In smaller bathrooms, particularly in older Richmond condos and townhomes, converting a tub-shower combo to a walk-in sometimes means the new shower is not dramatically larger than the old tub footprint — the gain is functional and visual rather than in raw square footage. A contractor should be honest about this trade-off during the planning stage rather than after tile is ordered.
What a Walk-In Shower Renovation Typically Costs
A straightforward walk-in shower conversion — replacing an existing tub-shower with a curbed walk-in, standard point drain, and a single glass panel — generally runs $12,000 to $20,000 depending on tile selection and finish level.
Curbless conversions, linear drains, and larger glass configurations push that range higher, often into the $20,000 to $35,000 range once structural floor work is involved. Natural stone tile, in-floor heating, and custom niches all add on top of that baseline.
Frequently Asked Questions
Is a curbless shower worth the extra cost?
For homeowners planning to stay in their home long-term, most find it worth it for both the accessibility benefit and the resale appeal — curbless showers consistently rank high on buyer wish lists across the region. For a shorter-term hold, a well-executed low-curb shower delivers much of the same visual benefit at a lower cost.
Can any bathroom be converted to a curbless shower?
Most can, but upper-floor bathrooms over wood framing sometimes require structural modification to create the necessary slope without a step, which can meaningfully increase cost. A site assessment before finalizing the design is the only reliable way to know.
How long does a walk-in shower renovation take?
A standard conversion typically takes one to two weeks from demolition to final walkthrough, including cure time for the waterproofing membrane and tile. Curbless conversions requiring structural floor changes can extend that timeline by several days.
Do walk-in showers need a door, or can they be fully open?
Fully open — doorless — configurations work well when the shower is recessed into an alcove or otherwise protected from spray, and they are popular in Coquitlam renovations where homeowners want the cleanest possible look. In more open layouts, a door or larger fixed panel is usually necessary to keep water contained.
Planning a Bathroom Renovation?
A walk-in shower renovation rewards the decisions made before construction starts far more than any choice made once tile is going up. Drain type, glass configuration, and waterproofing approach all deserve real consideration rather than a default selection.
