Bathroom Renovation Edmonton: Kerdi Shower in Spruce Grove

Basement Bathroom Renovation in Spruce Grove With a Fully Tiled Ceiling

This Spruce Grove renovation is a basement bathroom built the right way: a 12 by 24 porcelain shower surround in a random staggered pattern, a hexagonal mosaic shower floor, a matching hex mosaic across the entire shower ceiling, and a 12 by 24 porcelain floor field that wraps the rest of the bathroom. The reason we tiled the ceiling on this job is the reason every basement bathroom benefits from one: there are no windows down there, the ventilation through a single fan is rarely sufficient, and steam that escapes the shower envelope ends up condensing on a painted ceiling and eventually damaging the substrate.

Why Tile the Shower Ceiling in a Basement?

The standard upstairs approach (paint the shower ceiling with moisture-rated coating and run the bath fan) works when the bathroom has a window, an exterior wall, and proper attic ventilation above it. A basement bathroom has none of those. The ceiling sits under conditioned floor joists with no path for moisture to escape. Tiling the ceiling over a waterproof membrane creates a sealed envelope: steam condenses on the tile and runs back down into the shower drain instead of soaking into drywall and eventually into the structure above. It is the small detail that doubles the lifespan of a basement install.

Schluter Kerdi: The Waterproofing Layer Behind Every Wet Surface

Before any tile went on, we installed Schluter Kerdi Membrane across the full shower envelope: floor, four walls, and ceiling. Purpose: Kerdi is a polyethylene sheet membrane that creates a continuous vapor and water proof barrier behind the tile. Properties: it bonds to standard substrates with unmodified thinset, seams overlap with Kerdi-Band, and pre-formed corner pieces eliminate site-cut weak spots. Relationship: the Kerdi integrates with the Schluter drain and the curb as one continuous waterproof system. Skip any inch and you have a failure point.

We set the Kerdi in Premium Plus Mortar, the bond coat recommended for membrane to substrate. Same product carried the 12 by 24 wall tile up to the ceiling.

12 by 24 Walls in a Random Staggered Pattern, Plus a Waterfall Mosaic Insert

The shower walls are a 12 by 24 porcelain in a random stagger, with a vertical waterfall mosaic insert as the focal accent. The random stagger (as opposed to a perfect 50/50 brick lay) is the right pattern for large-format tile because it distributes any minor bow in the centre of each tile across the wall plane rather than stacking high points together. The waterfall insert breaks the field with a vertical column of mosaic that runs from near-ceiling down to the shower floor.

The Hexagonal Mosaic Ceiling and Shower Floor

The ceiling and shower floor both use a hexagonal mosaic, which is a single design decision that solves two different problems at once. On the floor: hex mosaic gives high slip resistance because the dense grout joint network creates traction, and the small format conforms to the slope of a sloped pre-pan. On the ceiling: hex on a mesh sheet installs faster than individual tile pieces on an overhead surface, and the small format hugs any minor undulation in the joist plane.

Bathroom Floor: Same 12 by 24, Different Thin-Set

The bathroom floor (outside the shower) uses the same 12 by 24 porcelain as the shower walls, in the same random stagger. We set the floor field in 253 Gold Laticrete Mortar, a polymer modified mortar with a high non-sag rating that performs well on large-format porcelain over a basement slab. Repeating the wall tile on the floor visually expands the bathroom and makes the shower curb the only transition the eye sees. The whole job was grouted with Prism Grout.

Spruce Grove Basement Bathroom FAQ

How long does a basement bathroom with a tiled ceiling take?
For a build with Kerdi waterproofing, 12 by 24 walls including the ceiling, hex mosaic floor and ceiling accent, plus a bathroom field, plan on 8 to 12 working days.

Will tiling the ceiling really make a difference vs paint?
In a basement, yes. The painted-ceiling approach fails because there is no exterior wall above to dry out a wet substrate. The tiled ceiling combined with a Kerdi membrane creates a fully sealed envelope.

Can the shower floor and ceiling really use the same mosaic?
Yes, as long as the floor side has appropriate slip resistance. Most hex mosaics are rated for wet area floor use, so repeating the same product on the ceiling is a design choice, not a compromise.
