How much does a complete shower renovation cost in a Calgary 1980s two-storey?

A complete shower renovation in a 1980s Calgary two-storey typically costs $4,000-$12,000, depending on whether you're updating the existing shower footprint or expanding the space and upgrading plumbing.

Most 1980s Calgary homes have builder-grade fiberglass shower stalls or basic ceramic tile surrounds that are ready for updating after 40+ years. The good news is that the plumbing rough-in from the 1980s is generally solid — you're likely looking at cosmetic and fixture upgrades rather than major plumbing overhauls, unless you want to relocate the shower or upgrade to multiple shower heads.

For a standard shower renovation keeping the existing footprint, expect $4,000-$7,500. This includes removing the old fiberglass surround or tile, installing proper waterproofing membrane (Schluter Kerdi system runs $3-$6 per square foot), new ceramic or porcelain tile ($15-$25 per square foot installed), updated shower valve and trim ($300-$800), and a frameless or semi-frameless glass enclosure ($1,200-$2,500). The existing drain location and plumbing connections stay the same, so no permits are required.

For a premium renovation with layout changes, costs jump to $7,500-$12,000+. This might include enlarging the shower by removing a bathtub, installing a custom tile bench, adding a second shower head or rain head, relocating plumbing lines, or creating a curbless walk-in shower. Layout changes require plumbing permits through the City of Calgary ($75-$150) and professional installation by a licensed plumber.

Calgary-specific considerations for 1980s homes are important for your renovation planning. Many 1980s bathrooms have plumbing in exterior walls — if your shower backs onto an exterior wall, ensure any new plumbing stays away from the cold side or includes proper insulation and heat trace cable. Calgary's chinook temperature swings stress grout and caulk over time, so invest in flexible grout ($2-$4 more per bag) and premium silicone caulk rated for extreme temperature ranges. The hard water in Calgary will leave mineral deposits on new fixtures and glass, so consider brushed nickel or matte black finishes instead of polished chrome, and apply a protective coating like EnduroShield to glass doors ($150-$300).

Waterproofing is absolutely critical and the most common corner-cutting mistake in shower renovations. Your 1980s shower likely has water damage behind the walls if it was never properly waterproofed originally. Budget $800-$1,500 for proper waterproofing membrane installation — this prevents the mould, rot, and structural damage that leads to costly tearout within 3-5 years. Never tile directly over drywall in a shower, even moisture-resistant green board. Use cement backer board (Durock, HardieBacker) or foam board (Schluter Kerdi Board) as your tile substrate.

Timeline for a complete shower renovation runs 5-10 business days once materials arrive. Demolition takes 1 day, plumbing rough-in (if needed) takes 1 day, waterproofing and backer board installation takes 1-2 days, tile installation takes 2-3 days, grouting and sealing takes 1 day, and glass installation takes 1 day. Allow 2-3 weeks total including material ordering and contractor scheduling.

What drives costs higher includes natural stone tile ($25-$50 per square foot installed), steam shower features ($2,000-$5,000), multiple shower heads with thermostatic valves ($800-$2,000), custom niches and benches ($500-$1,500), and radiant heated floors ($8-$15 per square foot). What keeps costs reasonable includes standard porcelain tile, keeping the existing plumbing layout, choosing a quality but not luxury shower valve, and selecting a semi-frameless glass enclosure instead of fully frameless.

This is definitely professional work — shower waterproofing, plumbing connections, and tile installation in wet areas require experienced contractors.
