Hidden Water Damage, a Rebuilt Shower, and a 12×24 70/30 Bathroom Package in Ozerna
Ozerna is a north-east Edmonton neighbourhood in the Castle Downs district, with a housing stock built largely through the 1980s. By the time an Ozerna ensuite reaches renovation age, a slow leak from an aging toilet or shower drain has often pooled under the original tile for years without surfacing as a visible problem. On this Ozerna project The Tile Experts started a routine tile-replacement scope and discovered exactly that: hidden water damage under the ensuite floor, soft drywall behind the shower surround, and a substrate that had to be cut open before any new tile could go down. With the homeowner’s authorization the scope expanded to include framing repairs, new drywall, a new shower pan, then a coordinated 12 by 24 install across the entire bath suite.
What We Found Under the Original Ensuite Floor
The renovation was scoped as a straightforward tile demolition and replacement: remove the original ensuite floor tile, prepare the substrate, install the new floor. What we discovered during demo: the previous toilet had been leaking slowly for an extended period, and the water had pooled under the original tile in a way that was completely invisible from above. The plywood substrate was soft, the drywall around the shower surround had absorbed water and lost structural integrity, and the stand-up shower base itself had compromised waterproofing at the curb. The decision point: a tile setter can lay new tile over compromised substrate and the floor will look fine for a year, but the failure cycle is on a clock from the moment the install is finished. The right call (which the homeowners approved) was to expand the scope, address the underlying damage, and rebuild the bathroom from the framing up.
The Rebuild: Framing, Drywall, and a New Shower Pan
With the original stand-up shower and the water-damaged drywall removed, the crew ran the structural repair scope. Framing: a small amount of new framing was added where the original studs had absorbed water, and every stud was confirmed dry and sound before any drywall went back. Drywall: new moisture-rated drywall was installed across the wet-zone walls, set to plane against the existing dry-zone walls so the new tile would lie flat across the transition. Shower pan: a new shower pan was set, levelled to the drain, and prepared for the tile assembly. Result: a bathroom that started this renovation as a hidden moisture problem and ended it as a fresh, dry, properly framed wet-zone ready for a coordinated tile install. This is the kind of scope expansion that protects a homeowner from chasing the same leak twice.
The 12×24 in a 70/30 Stagger Across the Whole Bath Suite
Once the rebuild was complete, the entire bath suite (the stand-up shower surround, the ensuite floor, the jacuzzi splash, the deck, the skirt, the main bathroom floor, the main bath tub surround, and a small vanity splash) was tiled in a single coordinated 12 by 24 porcelain in a 70/30 staggered pattern, set with 253 Gold Laticrete Mortar. Purpose: using one tile, one pattern, and one bond coat across every surface in both bathrooms turns a multi-room renovation into a single architectural composition. The eye reads the entire ensuite and main bath as one design language rather than as a stack of separately specified rooms. Property: the 70/30 stagger is the manufacturer-recommended layout for any rectified tile longer than 15 inches because it keeps adjacent tiles closer in bow profile and prevents the lippage that a 50/50 brick lay introduces at the long-tile centre. Relationship: 253 Gold Laticrete is a polymer-modified professional-grade thinset rated for porcelain in wet-zone applications, with the flexibility to absorb the seasonal movement an Ozerna wood-framed home lives through every year.
Why a Tile Base Is the Right Anti-Water-Damage Move
The homeowners specifically asked for a tile base around the bathroom perimeters as a barrier against any future water damage. Conventional approach: wood baseboard set against the drywall, with caulk at the floor-to-base joint. That works visually but the caulk is a service-life consumable; once it cracks, water at the floor level finds a path behind the baseboard and into the drywall. The tile-base move: a strip of the same 12 by 24 tile is cut and set as a base around the perimeter, with the tile face lying directly against the drywall and the tile-to-floor joint grouted with the same Prism grout as the rest of the floor. Result: no caulk in the service path, no wicking joint between the base and the drywall, and a perimeter detail that wraps the floor’s waterproofing up the wall by a full tile height. On a renovation where the homeowners just discovered what hidden water damage costs, the tile base is the detail that keeps it from happening again.

The Grout: Prism Across Every Surface
Every joint in the rebuild, the floor, the tub surround, the shower surround, the jacuzzi splash and deck and skirt, the vanity splash, and the tile base, was finished with Prism Grout. Purpose: Prism is a high-performance, stain-resistant calcium-aluminate cement grout that cures harder than standard portland-cement grout and resists efflorescence across joints exposed to water, soap residue, and seasonal humidity. Property: the calcium-aluminate chemistry holds its colour through years of bath cycles and shower use, which matters on a renovation where the homeowner has now seen what failing joints can hide. Relationship: using one grout chemistry across the entire scope keeps the joint tone consistent from the shower floor to the tile base to the jacuzzi deck, which is what makes the multi-room install read as one composition.
Ozerna Full-Suite Rebuild FAQ
How much does a full ensuite rebuild plus a coordinated main-bath tile install cost in Ozerna when hidden water damage is involved?
The scope depends entirely on the extent of the damage. For a project that includes framing repairs, new drywall, a new shower pan, plus 12 by 24 porcelain across the ensuite shower, floor, jacuzzi splash/deck/skirt, main-bath floor, tub surround, vanity splash, and tile base, plan on 22,000 to 38,000 dollars in tile-scope labour and material, depending on tile selection and the extent of the rebuild.
How do you find hidden water damage before starting a renovation?
You often cannot, because the damage hides under tile that still looks intact from above. The discipline is to plan for the possibility: scope the demolition carefully, set a contingency budget for what might be discovered under the original substrate, and treat any soft plywood or compromised drywall as a scope expansion rather than as a problem to paper over.
Why install a tile base instead of wood baseboard in a bathroom?
A wood baseboard relies on caulk at the floor joint to keep water out, and caulk is a service-life consumable. A tile base eliminates that joint by wrapping the floor’s waterproofing up the wall by a full tile height with a grouted joint instead of a caulked one. See our bathroom tile installation service.
