A Kerdi-Membrane Custom Shower Build From Bare Wall in Beaumont
Beaumont sits immediately south of Edmonton, with a fast-growing new-build housing stock that has expanded steadily across the past decade. Custom shower scopes in Beaumont production homes typically follow a standardized waterproofing sequence where the wet-zone build is documented step by step, because the warranty implications of a leaking shower are severe enough that every builder in the market specifies a bonded waterproofing membrane behind the tile. On this Beaumont new build The Tile Experts ran a full custom shower from bare studs through to grouted finish: Schluter Kerdi membrane on every shower wall, a custom-built shower curb, drain kit installation, 12 by 12 wall tile in a straight lay set with Premium Plus Mortar, and then the jacuzzi tub deck and skirt plus bathroom floor in 12 by 12 set with VersaBond, all grouted with Prism.
Why Schluter Kerdi Is the Standard for a Custom Shower Build
Every wet-zone wall in this Beaumont shower was covered in Schluter Kerdi membrane before any tile went up. What Kerdi is: Kerdi is a thin pliable polyethylene waterproofing membrane bonded to a fleece-laminated fabric on both faces, designed to be adhered directly to drywall with thinset and then tiled over. The membrane creates a continuous waterproof barrier between the wet zone of the shower and the structure behind it. Why bonded waterproofing matters: conventional shower wall construction depends on cement board, vapour barrier behind the cement board, and a top coat of liquid waterproofing at the seams, with the assumption that water that penetrates the tile and grout will be stopped by one of those layers before reaching the structure. A bonded membrane like Kerdi eliminates the gap by waterproofing the entire wall surface uniformly, with every seam between membrane sheets sealed using a Kerdi-band overlap and a thinset bond. The construction sequence: drywall is installed first (the membrane bonds directly to drywall in a Kerdi-rated assembly, which is why a properly waterproofed Kerdi shower can use drywall instead of cement board), the Kerdi sheet is troweled onto the drywall with thinset, the seams are overlapped with Kerdi-band, and the entire assembly is allowed to cure before tile installation begins. The shower curb and drain kit: the curb was constructed in place and waterproofed with Kerdi membrane on every face, the drain kit was integrated with the Kerdi shower pan, and the entire assembly forms one continuous waterproof envelope. This is the difference between a shower that lasts 30 years and a shower that fails at year 8.
The 12×12 Wall Tile in a Straight Lay
The shower walls on this build were specified by the builder in a 12 by 12 tile installed in a straight lay. Why 12 by 12 in a custom shower: the 12 by 12 reads as more architectural and contemporary than a 3 by 6 subway surround, with fewer joints per square foot. Fewer joints means fewer joint maintenance points across the life of the shower, and a cleaner overall reading of the wet-zone wall. Why a straight lay: a straight lay matches the conventional residential shower install pattern and produces a calm grid that does not compete with the shower fixtures or the bathroom design language. The straight lay is also the easiest format to keep dead-square against the shower corners, which matters on a 12 by 12 because any layout drift would show up as a sliver cut at the corner. The bond coat over Kerdi membrane: the shower wall tile was set with Premium Plus Mortar, a polymer-modified thinset rated for installation directly over the Kerdi membrane. The chemistry compatibility between the membrane and the bond coat is what makes the Kerdi assembly work as a single continuous waterproofed wall, and using a non-rated thinset on a Kerdi shower would void the membrane warranty and risk delamination across the wet-zone life of the install.
The Jacuzzi Tub Deck, Skirt, and Bathroom Floor
Once the shower was complete the install moved to the jacuzzi tub assembly and the bathroom floor, both also specified in 12 by 12 tile. The jacuzzi tub deck: the horizontal surface around the jacuzzi tub opening, tiled in 12 by 12 with VersaBond. The jacuzzi tub skirt: the vertical front face of the jacuzzi assembly, also tiled in 12 by 12 with the same VersaBond. The bathroom floor: the main bathroom floor outside the shower enclosure, tiled in 12 by 12 in a continuation of the same straight lay used on the shower walls. Why VersaBond on the deck, skirt, and floor while the shower walls use Premium Plus: the jacuzzi deck and skirt sit in a splash-exposed environment but not in continuous wet-zone exposure (the way a shower wall does), and the bathroom floor outside the shower enclosure also sits in a moisture-cycling environment but not continuous water contact. VersaBond Mortar is the polymer-modified portland-cement thinset rated for those surface types, with the bond strength to carry 12 by 12 on horizontal and vertical residential applications and the polymer modification that handles substrate cycling. The chemistry split is intentional: Premium Plus over Kerdi inside the shower envelope, VersaBond on the splash-exposed and traffic surfaces outside it. Two thinsets in one bathroom, each matched to its surface environment.
Why Prism Grout Across the Whole Bathroom
Every joint across this build (shower walls, jacuzzi deck and skirt, bathroom floor) was grouted with Prism Grout. Why one grout across the whole bathroom: Prism is a high-performance, stain-resistant calcium-aluminate cement grout that performs across wet-zone wall, splash-zone deck, and traffic floor applications. Using one grout across the entire bathroom keeps the joint colour reading consistent room to room and simplifies both the install workflow and the homeowner’s long-term cleaning. Why Prism specifically: the calcium-aluminate chemistry resists efflorescence (the white powdery deposit that can develop on cement grouts in continuous moisture exposure), holds its colour reading across years of cleaning-product exposure, and is rated for both wet-zone and dry-zone applications. The full bond and grout system: Kerdi membrane plus Premium Plus thinset plus Prism grout inside the shower envelope, VersaBond plus Prism on the deck, skirt, and floor. This is a fully manufacturer-coordinated specification, not a mix of incompatible products picked on price.

Beaumont Custom Shower FAQ
How much does a Kerdi-membrane custom shower plus jacuzzi tub assembly and bathroom floor cost in a Beaumont new build?
For a project of this scope (Kerdi membrane on every shower wall plus the curb and pan, Premium Plus Mortar bond coat, 12 by 12 wall tile in a straight lay, jacuzzi tub deck and skirt in 12 by 12 with VersaBond, bathroom floor in 12 by 12 with VersaBond, full Prism grout finish), plan on 8,500 to 14,500 dollars in tile-scope labour and material, with shower square footage and jacuzzi assembly geometry as the primary cost drivers.
Why use Schluter Kerdi instead of cement board with a top-coat waterproofer?
Kerdi is a bonded waterproofing membrane that creates a continuous waterproof barrier across the entire shower wall surface, with seams sealed via Kerdi-band overlap. Conventional cement board with top-coat waterproofing depends on multiple layers each handling a portion of the waterproofing job, and the failure modes are concentrated at the seams. Kerdi eliminates the seam-failure mode by waterproofing uniformly.
Why does the shower wall use Premium Plus Mortar while the floor uses VersaBond?
Premium Plus is rated for installation directly over the Kerdi membrane inside the shower envelope, where the chemistry compatibility between the membrane and the bond coat is what makes the Kerdi assembly work. VersaBond is the right bond coat for the splash-exposed jacuzzi deck and skirt and the traffic-exposed bathroom floor outside the shower envelope. Two thinsets in one bathroom, matched to surface environment. See our bathroom tile installation service.
