Tiling a shower is one of the most skill-dependent jobs in a bathroom renovation — poor waterproofing or tiling technique leads to leaks and expensive remediation. Here's what shower tiling costs in NZ in 2026, what's involved, and what to look for in a tiler.

Shower Waterproofing — The Non-Negotiable First Step
Before a single tile goes on the wall, a shower must be waterproofed. This is a Building Code requirement (Clause E3) and the step most likely to cause long-term failure if done incorrectly.
Approved waterproofing systems used in NZ: - Mapei: Mapelastic, Mapegum WPS — brush-applied membrane systems - Ardex: Ardex 8+9, Ardex WPM systems - Davco: Davco Sanitex, Waterproof Plus - GCP (Grace): Preprufe and waterproofing systems
What waterproofing covers: Floor, walls to at least 1800mm height (or full height), and all corners and junctions (corner joints get reinforced with fabric tape embedded in membrane — the most common failure point).
Curing time: Waterproofing membranes need 24–48 hours to cure before tiling can begin. The inspection stage (if consented) happens at this point — building inspector checks the membrane before it's covered with tiles.
Do not skip or rush this step. A shower that leaks behind tiles requires complete tile and substrate removal to fix — typically $5,000–$15,000 in remediation.
Tile Selection for Showers
Wall Tiles
Ceramic: Most affordable, lighter than porcelain, easier to cut. Slightly more porous than porcelain — suitable for shower walls when properly grouted and sealed.
Porcelain: Denser, lower porosity, harder-wearing. Better for floor applications but also excellent for walls. Larger format available.
Large format (300×600 or larger): Fewer grout lines, contemporary look, but requires a very flat substrate (lippage — tile edges not level — is more noticeable with large tiles). More difficult to cut (wet saw required).
Subway tile (75×150 or 100×200): Classic, versatile, works with most bathroom styles. NZ's most popular shower tile format. Good balance of cost and appearance.
Mosaic: Small tiles on mesh sheets. Popular as a floor tile (follows contours, provides grip, many small grout lines drain well) or as a feature strip. More grout lines mean more maintenance.
Floor Tiles
Shower floors need: - Slip resistance: R10 or R11 slip rating minimum (R10 = standard wet area, R11 = higher grip) - Small format or mosaic: Follows the floor fall to the drain — large flat tiles over a slightly uneven fall look poor - Grout: Non-sanded grout for tight joints (under 3mm), sanded grout for wider joints
Colour grout vs white grout: White grout is harder to keep clean in a shower floor. Mid-tone grey grout is the most practical choice for NZ shower floors — hides soap scum and hard water marks better.
What a Tiler Does
Substrate prep: Check wall substrate is flat, fix any high/low spots, prime if required by the adhesive manufacturer.
Waterproofing (some tilers, or separate waterproofer): Apply membrane, tape corners, allow to cure.
Layout: Plan the tile pattern — where cuts fall, how tiles align across the shower, feature tile placement.
Fix wall tiles: Apply adhesive, set tiles with correct joint spacers, check level and plumb continuously.
Fix floor tiles: Set to the correct fall toward the drain — critical for water drainage.
Grouting: Apply grout after adhesive cures (usually 24 hours), clean off excess, tool joints.
Silicone joints: All corners and junctions where tile meets tile at 90° are sealed with silicone (not grout) — silicone flexes with movement; grout cracks.
Total elapsed time for a standard 900×900 shower recess: 4–7 working days (waterproofing + cure, tiling, adhesive cure, grouting, silicone).
What to Look for in a Shower Tiler
Shower tiling is the highest-stakes tiling job — the waterproofing and waterproof junction details directly affect whether the shower leaks.
Questions to ask: 1. What waterproofing system do you use, and who applies it? 2. Do you use corner fabric tape at all internal corners? 3. Are you familiar with the Building Code E3 requirements for wet areas? 4. Can you show me examples of previous shower tiling work (photos)? 5. Do you use a wet saw for cutting (not an angle grinder, which can crack tiles)? 6. Is silicone at all corners included in your quote? 7. What tile adhesive brand and grade are you using?
Red flags: - Doesn't mention waterproofing at all - Quotes without seeing the job (substrate condition matters) - Uses cement sheet "instead of" membrane (substrate type doesn't replace waterproofing) - Won't provide references for previous shower work

Frequently Asked Questions
How much does it cost to tile a shower in NZ? Labour only (tiler): $1,200–$3,000 for a standard 900×900 recess. Including waterproofing and tile supply (basic ceramic): $2,000–$4,500. Mid-range porcelain: $3,000–$6,500. A large walk-in with feature tiles: $6,000–$14,000.
How long does shower tiling take in NZ? A standard 900×900 shower: 4–7 working days. This includes waterproofing cure time (24–48hrs), tile adhesive cure (24hrs before grouting), and grouting. Total elapsed time from start to usable shower: 7–10 days in most cases.
What tiles are best for NZ showers? Porcelain tiles for walls (low porosity, durable), and small-format porcelain or mosaic tiles for floors (R10/R11 slip rating). Subway tiles (100×200mm) remain the most popular NZ shower wall tile. For floors, 50×50mm or 100×100mm mosaic with drainage-friendly grout spacing.
Can I tile my own shower in NZ? Wall tiling DIY is feasible with patience and correct tools (wet saw, notched trowel, spacers). The critical step — waterproofing membrane application — should be done correctly even by a DIYer (products are available at tile shops). Floor tiling requires accurate fall to the drain — this is harder to DIY well. If the shower is consented, the waterproofing inspection must be passed before tiling.
Why do shower tiles leak in NZ? The most common causes: failed waterproofing membrane (often at corners where fabric tape wasn't used), cracked grout joints that allow water behind tiles, or grout instead of silicone at movement joints (corners). A well-built shower shouldn't leak — if yours does, the repair involves removing tiles to access the substrate.
