Whole-Home Tile Renovation in Highlands: Kerdi Bath, 12×24 Walls, and a 6×24 Backsplash
Highlands is one of Edmonton’s earliest streetcar neighbourhoods, sitting on the north bank of the river east of downtown, with a housing stock dominated by character homes built between 1910 and 1930 alongside post-war infill. Renovations in Highlands carry the design weight of the original architecture, which means the tile work has to read as deliberate and architectural rather than as a generic builder finish. On this Highlands project The Tile Experts handled a full upstairs-and-down tile package: a Kerdi-waterproofed bathroom with a 12 by 24 wall feature run as a 70/30 staggered field, a pony wall and accent wall in the same tile, a waterfall mosaic and a bright shower-floor mosaic, plus a 12 by 24 kitchen floor and a 6 by 24 backsplash with a mosaic insert.
The Kerdi Bathroom: A Waterproofed Envelope Behind Everything
The renovation started in the bathroom with a Schluter Kerdi Membrane bonded to the wall substrate with Premium Plus Mortar. Purpose: Kerdi creates a continuous waterproof barrier between the tile and the drywall, so every wet-zone surface (the back wall feature, the pony wall, the half-wall wrap, and the shower floor) lives behind one engineered envelope rather than relying on the tile and the grout to keep water out. Property: the bonded sheet membrane is sealed at every seam with Kerdi-Band and reinforced at every internal corner with a preformed Kerdi-Kereck. Relationship: setting the membrane with the bond coat that the manufacturer rates for the assembly is what makes the waterproofing perform as one engineered system, and it is the reason a Highlands character home built in the 1920s can carry a bathroom that will outlast the next renovation cycle.
Self-Leveling Clips on the Bathroom Floor: Zero Lippage
Before any wall tile went up, the bathroom floor was tiled with self-leveling clips at every joint. Mechanism: a clip is set into each joint, a wedge is driven through the clip to mechanically force adjacent tiles into the same plane while the bond coat cures, and the clip body is broken off flush once the mortar has set. Purpose: a Highlands character home has lived 90+ years of seasonal movement, so any minor variation in subfloor flatness is a given and the install discipline has to compensate. Result: every joint sits at exactly the same elevation, the floor reads as one continuous plane, and there is no lippage anywhere across the bathroom. This is the discipline that separates a professional install from a generic one, particularly on a heritage home.
The 12×24 Wall Tile in a 70/30 Staggered Pattern
The bathroom walls (the back wall feature, the pony wall in full, and a half-wall wrap on the remaining surfaces) all carry a 12 by 24 tile in a 70/30 staggered pattern, set with Premium Plus Mortar. Purpose: a 70/30 stagger (every course offset by 30 percent of the tile length rather than the classic 50 percent brick lay) is the recommended pattern for any rectified tile longer than 15 inches because it stays inside the manufacturer’s tolerance for tile bow. The result is a wall that reads contemporary and architectural without the lippage that a 50/50 layout would introduce at the long-tile centre. Property: Premium Plus is a polymer-modified thinset rated for both the Kerdi membrane and for the tile back, so the bond chemistry is consistent from the substrate face through the tile face. Relationship: running the same 70/30 layout from the back wall feature through the pony wall and the half-wall wrap unifies the bathroom as one design composition.
Two Mosaic Accents: Waterfall and Shower-Floor Pop
The homeowner asked for two distinct mosaic accents in the bathroom: a waterfall mosaic running vertically up one wall and a bright mosaic on the shower floor as a colour pop. Visual story: the waterfall mosaic sets a focal axis through the room, giving the eye a clean vertical line to read against the staggered 12 by 24 field, while the bright shower-floor mosaic introduces a deliberate colour accent at the place where the homeowner stands every morning. Layout discipline: both mosaics had to land on full-tile boundaries within the 12 by 24 field, so the field layout was planned around the mosaic placement rather than the other way around. Result: two accents that read as designed-in rather than dropped-in, which is the difference between a custom bathroom and a builder-grade one.
Upstairs Kitchen: 12×24 Floor and a 6×24 Backsplash With Mosaic Insert
The upstairs kitchen carries a 12 by 24 tile floor in the same 70/30 staggered pattern as the bathroom walls, set with VersaBond Mortar (the right bond coat for a kitchen-floor environment). The backsplash uses a 6 by 24 tile with a mosaic insert, set with ReliaBond Tile Adhesive. Purpose: the 6 by 24 backsplash format reads as a contemporary update of the classic 3 by 6 subway, while the mosaic insert gives the wall a focal accent behind the range. Property: ReliaBond is a Type 1 organic mastic engineered for interior dry-wall installations like a kitchen backsplash, with the grab strength to hold the 6 by 24 tile vertically without sag. Relationship: running the same 12 by 24 tile through the bathroom walls and the kitchen floor ties the upstairs and the downstairs together as one design language, which is the layout discipline a Highlands character home rewards.

Why Stagger 12×24 at 70/30 Instead of 50/50
Manufacturers of long rectified tiles (anything over 15 inches in length) recommend a stagger of 33 percent or less rather than the classic 50 percent brick lay. Reason: a long porcelain tile inherently has a small amount of bow across its length, and a 50/50 brick lay puts the maximum bow of one tile directly against the minimum bow of the next, which produces visible lippage at the joint centre. A 70/30 stagger keeps adjacent tiles closer in bow profile, which keeps the joint flush. Result: on this Highlands renovation every 12 by 24 joint sits flush, the wall reads as one continuous plane, and the install respects the manufacturer’s published specification. This is the kind of detail that separates a tile crew that follows engineering from a crew that just lays tile.
Highlands Whole-Home Tile FAQ
How much does a Kerdi bathroom plus a 12×24 kitchen floor and 6×24 backsplash cost in Highlands?
For a project of this scope (full Kerdi bathroom with 12 by 24 walls, pony wall, waterfall mosaic, bright shower-floor mosaic, plus an upstairs 12 by 24 kitchen floor and a 6 by 24 backsplash with mosaic insert), plan on 15,500 to 26,500 dollars in tile-scope labour and material, depending on tile selection.
Why use self-leveling clips on a 12×24 bathroom floor in an older Highlands home?
Heritage homes have lived decades of seasonal movement, and any minor variation in subfloor flatness is amplified by the larger 12 by 24 face. Clips mechanically force adjacent tiles into the same plane while the mortar cures, so the floor reads as one continuous surface with zero lippage. On a long-rectified format in a character home, the clips are non-optional.
How long does a whole-home Highlands tile renovation of this scope take?
For a full Kerdi bathroom rebuild plus an upstairs kitchen floor and backsplash, plan on three to four weeks of tile work staged across the plumbing, electrical, and finish trades.
