Bathroom Tiling Layout Options
How far up the walls you tile dramatically affects both the look and the cost:
Floor only: Most cost-effective. Tiles on floor, painted walls. Practical but less premium. Popular for separate toilet rooms.
Splash zone (to 1200mm): Tiles on wet walls (behind vanity, around toilet) to 1.2m — protects the walls most likely to get splashed. Painted walls above.
Half height (to 1800mm): Tiles to door height — a clean, popular NZ bathroom look. Reduces painting above the tile line.
Full height (floor to ceiling): All walls tiled. The most premium look, easiest to clean, but the highest cost. Very popular for master ensuites in NZ.
Tile Selection Guide for NZ Bathrooms
Floor Tiles
Slip resistance is a Building Code requirement for wet areas — tiles must meet a minimum R10 rating (higher R = more grip). Standard floor tiles for bathrooms are typically R10; shower floors R10–R11.
Porcelain: Dense, low porosity, durable. Excellent for bathroom floors. Available in endless sizes and finishes.
Ceramic: Lighter and more affordable than porcelain, slightly more porous. Fine for bathroom floors when properly sealed.
Large format (600×600mm+): Fewer grout lines, very contemporary. Requires a very flat substrate — lippage (uneven edges) is more visible on large tiles. More expensive to lay.
Mosaic (50×50 or smaller): Many grout lines — provides grip, follows floor fall easily. Popular for shower floors.
Wall Tiles
Subway (75×150mm or 100×200mm): The most popular NZ bathroom wall tile. Works with every style — classic, modern, or retro depending on grout colour and layout pattern.
Rectangular long format (150×600mm or 100×300mm): More contemporary than square tiles. Can be laid horizontally or vertically.
Large format (300×600 or 300×900): Modern, minimal grout lines. Requires precise adhesive thickness and levelling clips.
Handmade/artisan tile: Irregular surface and glaze — distinctive, premium look. More expensive. Popular for feature walls.
Grout Colour
Grout colour dramatically affects the look: - White grout: Classic but shows dirt on floors. Good for white subway wall tiles. - Grey grout (mid-tone): The most practical choice for floors and showers — hides soap scum, hard water marks. - Dark grout: Strong contrast with light tiles — bold look. Harder to keep looking clean. - Matching grout: Same colour as tiles — minimalist, grout lines visually disappear.
Epoxy grout: More stain-resistant and durable than cement grout — worth specifying for high-traffic floors and shower floors. More expensive to apply ($15–$30/m² extra).
Substrate — What Tiles Can Go On
Concrete slab: Ideal tile substrate — flat, stable, not moisture-affected.
Timber subfloor: Tiles can go on timber if the subfloor is rigid enough (deflection must be under 1/360 of span). Often requires cement board overlay over existing timber to stiffen it. Timber floors flex; tiles crack. This must be done correctly.
Existing tiles: Possible if firmly bonded and flat, but adds floor height and requires careful adhesion assessment. For wet areas (showers), always remove existing tiles before waterproofing — never tile over existing shower tiles.
GIB board (bathroom areas): Standard GIB board is not suitable for wet areas — use moisture-resistant GIB (GIB Aqualine) as a minimum, or cement board (Hardibacker, Villaboard) for shower walls. Cement board takes tile adhesive better and is completely waterproof.
The Tiling Process
A full bathroom tiling job follows this sequence:
- Substrate prep — check for flat, solid surface; fix any high/low spots
- Waterproofing (wet areas) — membrane applied, corners taped, cure 24–48 hrs
- Layout planning — set out tiles from centre or feature point, plan where cuts fall
- Floor tiles — adhesive, level, spacers, allow cure
- Wall tiles — adhesive, level and plumb, spacers
- Grout — after adhesive cures (24hrs minimum), apply grout, clean
- Silicone — all corners and junctions between different planes (never grout at corners)
- Finishing — clean residual grout haze, polish
Elapsed time for a full bathroom tile job: 7–14 working days including waterproofing cure, adhesive cure, and grouting.
Questions to Ask a Bathroom Tiler
- What waterproofing system do you use for wet areas?
- Do you use fabric tape at internal corners in the waterproofing?
- What adhesive are you using — flexible or standard (flexible is required for timber subfloors)?
- Is epoxy grout available, and what is the cost difference?
- Do you supply tiles or should I?
- What is the total area you're quoting, and have you included feature tile areas separately?
- What is your lead time to start?

Frequently Asked Questions
How much does it cost to tile a bathroom in NZ? A shower recess only (supply + labour): $2,500–$6,500. A half-tiled bathroom (floor + shower walls): $4,000–$10,000. A fully tiled bathroom (all walls + floor): $7,000–$18,000. Prices depend heavily on tile selection, bathroom size, and Auckland vs regional pricing.
What tiles are best for a NZ bathroom? Floor: porcelain with R10 slip rating in 300×300mm or similar. Shower walls: porcelain or ceramic — subway tiles remain the most popular NZ choice. Large format for a more contemporary look. Avoid polished marble on floors (slippery when wet) and porous natural stone without sealing.
How long does bathroom tiling take in NZ? A shower recess: 4–7 working days. A full bathroom tile: 10–15 working days. Elapsed time includes waterproofing cure (1–2 days), adhesive cure (1 day), and grouting. Don't use the shower until silicone has cured fully (24–48 hours after application).
Can I tile over existing bathroom tiles in NZ? For non-wet areas (bathroom floor that isn't in a shower): sometimes yes, if existing tiles are firmly bonded. For shower areas: always remove existing tiles and apply fresh waterproofing membrane — you cannot apply membrane over existing tiles.
Do bathroom tiles need to be sealed in NZ? Porcelain: generally no sealing required (very low porosity). Ceramic: floor tiles may benefit from sealing. Natural stone (marble, travertine, slate): always seal before grouting and annually thereafter. Grout: sealing grout joints (especially on floors) reduces staining and is recommended every 1–2 years.
