Bathroom Renovation Edmonton: Kerdi Shower in Glenora

A Fully Waterproofed 12×24 Stacked-Lay Shower With a Waterfall Mosaic Insert in Glenora

Glenora is one of Edmonton’s most established premium residential neighbourhoods, sitting west of 121 Street between Stony Plain Road and the North Saskatchewan River valley, with a housing stock that runs from 1920s and 1930s character homes through mid-century rebuilds and contemporary infills. New builds in Glenora are infill projects on demolished lots inside one of the city’s most architecturally protective communities, which means the build specification has to match a premium neighbourhood standard while staying within the lot-coverage and heritage constraints of the area. On this Glenora new build The Tile Experts ran a fully waterproofed wet-zone assembly with Schluter Kerdi Membrane bonded with Premium Plus Mortar, then set 12 by 24 porcelain in a stacked-lay pattern across both the shower walls and the bathroom floor (with a waterfall mosaic insert in the shower), using Premium Plus on the wet-zone walls, curb, bench, and shower floor and 253 Gold Laticrete Mortar on the bathroom floor, all grouted with Prism Grout.

Why a Schluter Kerdi Waterproofing Assembly Is the Right Glenora New-Build Spec

The wet-zone assembly on this build starts with a Schluter Kerdi waterproofing membrane bonded to the substrate with Premium Plus Mortar before any tile work begins. What a Kerdi assembly is: Schluter Kerdi is a polyethylene waterproofing and vapour-retarding sheet membrane that gets bonded to the wall, curb, bench, and shower floor substrate with a polymer-modified thinset, creating a continuous waterproof envelope behind the tile work. The seams between sheets are sealed with Kerdi Band and Kerdi corners, and the result is a wet-zone assembly that contains water inside the tile finish rather than relying on the tile and grout layer alone to keep water out. Why this matters on a premium Glenora build: the warranty life of a wet-zone tile assembly is determined by the waterproofing under the tile rather than by the tile itself. A shower without a dedicated waterproofing membrane relies on the grout joints and the tile bond coat to keep water out of the wall cavity, and over a 15 or 20 year horizon, every grout joint will eventually let some moisture through. A Kerdi assembly behind the tile means that even when grout ages or microcracks form at the corner movement zones, the wall cavity stays dry. On a premium build aimed at a 30 plus year ownership cycle, the Kerdi spec is the correct one. The bond coat for the Kerdi: the membrane was bonded to the substrate with Premium Plus Mortar, the polymer-modified thinset specified by Schluter for Kerdi installations. The same chemistry was then used to set the tile on top of the membrane, which keeps the bond coat chemistry continuous from substrate to membrane to tile. What this delivers: a wet-zone assembly where every layer (substrate, membrane bond, tile bond) shares the same polymer-modified chemistry, with no chemistry-transition risk between layers.

The 12×24 Stacked Lay Across Walls and Floor

The tile spec on this build is a 12 by 24 porcelain installed in a stacked-lay pattern across both the shower walls and the bathroom floor. What a stacked lay means: every tile is positioned directly above the tile below, with the vertical and horizontal joints aligning to form a grid of squares (or in this case, rectangles repeating every 12 by 24 unit). Unlike a brick lay (50 percent offset) or a 70/30 staggered lay, the stacked lay produces a grid that reads as architectural and contemporary rather than traditional. Why a stacked lay on a premium Glenora build: the stacked lay is the most contemporary tile pattern available and the one that reads cleanest at premium-finish levels. The aligned joints create a visual grid that connects with the geometry of contemporary cabinetry, plumbing fixtures, and architectural lines, and the lack of offset means the eye does not register a stepped pattern when reading the wall. The result is a wet-zone finish that looks calibrated rather than decorated. Why the same stacked lay across walls and floor: running the stacked lay on both surfaces produces a continuous grid that connects from horizontal to vertical at the base of the shower, where the floor joint lines align with the wall joint lines at the perimeter. The continuity at the wall-floor transition is one of the highest-value details in a premium bathroom install. Why 12 by 24 specifically: the 12 by 24 has the right proportion for both the shower wall (where the 24 inch dimension carries up the wall and reduces the number of horizontal joints) and the bathroom floor (where the 24 inch dimension reduces the joint count across the floor). A smaller format would have read as busier on both surfaces, and a larger format would have demanded a different bond coat specification on the floor. The lippage risk: a stacked lay on a 12 by 24 is the most lippage-sensitive pattern available, because every joint corner aligns with the corner of the adjacent tile, and any high or low edge reads immediately against the aligned grid. The install requires careful flatness work on the substrate before the membrane goes down, plus disciplined back-buttering on every tile.

The Waterfall Mosaic Insert in the Shower

The design hook in the shower is a waterfall mosaic insert, a vertical band of mosaic tile running floor-to-ceiling on one shower wall to interrupt the 12 by 24 stacked field. What a waterfall mosaic insert is: a vertical column of small-format mosaic tile (typically 1 by 1 or 2 by 2 mosaic on a mesh sheet) running from the shower floor to the shower ceiling, positioned on the back wall or a sidewall as a single design moment. The vertical orientation references a waterfall, with the mosaic facets catching light and reading as a textured vertical surface against the calmer 12 by 24 field. Why a vertical waterfall on a stacked-lay field: the stacked lay reads as a grid of horizontal and vertical lines in equal weight, and a vertical waterfall insert reinforces the vertical reading without competing with the grid. A horizontal accent band (like a 6 inch insert at a fixed elevation) would have cut across the vertical grid lines and read as an interruption, while the waterfall runs parallel to the grid and reads as an integration. Why a single-wall waterfall and not a multi-wall mosaic: a single waterfall is a deliberate design moment, while a multi-wall mosaic would have read as fragmentation. The single insert is the move that signals premium intent without committing to a fully clad mosaic shower. The bond coat for the mosaic and the field: both the 12 by 24 field and the mosaic waterfall were set with Premium Plus, the same chemistry that bonds the Kerdi membrane to the substrate. The chemistry-continuous assembly means that the bond coat performance is uniform from substrate through membrane through tile, with no chemistry transition risk at the mosaic boundary. The grout: the joints across the 12 by 24 field and the mosaic waterfall were grouted with Prism, which keeps the joint colour reading continuous across the format transition.

Why Two Bond Coats Across the Same Bathroom

The bathroom uses two different bond coats: Premium Plus on the wet-zone walls, curb, bench, and shower floor, and 253 Gold Laticrete on the bathroom floor. Why the split makes sense: the wet-zone surfaces sit on top of the Kerdi membrane and require a bond coat that is chemistry-compatible with both the membrane and the tile, which is what Premium Plus is rated for in the Schluter system. The bathroom floor sits outside the membrane envelope on a conventional substrate, and the 24 inch face dimension on the 12 by 24 floor tile means the bond coat has to maintain its thickness under the larger tile footprint. 253 Gold Laticrete is the medium-bed thinset that handles the 12 by 24 floor format on a conventional substrate. What Premium Plus delivers on the wet-zone: a polymer-modified thinset rated by Schluter for use with Kerdi membranes, with the chemistry stability to bond the membrane to the substrate, the tile to the membrane, and to handle the moisture-cycling environment of the wet-zone over the warranty life of the assembly. What 253 Gold delivers on the floor: a polymer-modified medium-bed thinset specifically engineered for large-format tile, with the bond strength and the slump-resistance to maintain bond coat thickness under the 12 by 24 footprint without producing centre voids. Why this matters on a premium build: matching the bond coat to the specific substrate environment and tile format produces a fully load-rated assembly with no compromise in any zone. A single bond coat across both wet-zone and bathroom floor would compromise the performance in one direction or the other, and on a premium build aimed at a 30 plus year ownership cycle, the chemistry split is the right call.

Glenora New Build FAQ

How much does a premium new-build bathroom with a Kerdi-waterproofed shower, 12×24 stacked lay, and waterfall mosaic insert cost in Glenora?
For a project of this scope (Schluter Kerdi membrane bonded with Premium Plus, 12 by 24 porcelain in a stacked lay across shower walls, curb, bench, shower floor, and bathroom floor, waterfall mosaic insert in the shower, 253 Gold Laticrete on the bathroom floor, full Prism grout finish), plan on 12,500 to 19,500 dollars in tile-scope labour and material, with shower square footage and bathroom floor square footage as the primary cost drivers.

Why use a Schluter Kerdi membrane behind the tile instead of relying on the tile and grout to keep water out?
The warranty life of a wet-zone tile assembly is determined by the waterproofing under the tile. Grout joints and bond coats alone will let some moisture through over a 15 to 20 year horizon. A Kerdi membrane contains water inside the tile finish, keeping the wall cavity dry even as grout ages.

Why is the stacked lay considered more contemporary than a brick lay or staggered lay?
The stacked lay aligns every joint into a clean grid that reads as architectural and calibrated, connecting with the geometry of contemporary cabinetry and fixtures. A brick lay or staggered lay reads as more traditional. See our bathroom tile installation service.
