Shower Types Compared
Prefab Acrylic or Fibreglass Shower
A one-piece or multi-piece moulded unit that arrives complete — walls and base in one. Installed directly to the framing or existing walls.
Advantages: Fast installation (1–2 days), no grout lines (easier to clean), lower cost, no waterproofing required (the material is waterproof).
Disadvantages: Standard sizes only (common: 900×900, 1000×1000, 1000×800), less premium look, can't be customised. May look dated in a renovated bathroom. Size constraints are limiting for larger walk-in showers.
Best for: Rental properties, quick bathroom refreshes, or where budget is the primary consideration.
Tiled Shower (Fully Tiled Recess or Walk-In)
Tile adhesive, waterproof membrane, tiles, and grout over a screeded or tiled base. Completely custom in size and tile selection.
Advantages: Any size, any tile, any configuration. Premium appearance. Adds more to bathroom value and resale price. More durable surface than acrylic when done well.
Disadvantages: More expensive, takes longer (tiling + drying time), grout lines require periodic resealing and cleaning, waterproofing must be done correctly (non-negotiable under NZ Building Code E3).
Best for: Main bathrooms, ensuites, design-led renovations, any shower where you want a premium result.
Walk-In Shower (No Screen or Minimal Screen)
Open shower with no door, or a single glass panel. Increasingly popular in NZ for its clean, accessible look. Requires careful floor fall design (water must flow to drain without splashing out of the shower area).
Minimum practical size for a walk-in: 1200×900mm. 1500×1000mm is more comfortable.
Waterproofing: Non-Negotiable
NZ Building Code Clause E3 requires wet areas (shower, bath area, toilet in some configurations) to be waterproofed to prevent moisture affecting the building structure. This is not optional.
A tiled shower without proper waterproofing will fail — water penetrates grout and tile adhesive, reaches the framing, and causes timber rot and mould. This is one of the most expensive remediation jobs in NZ bathrooms — typically requiring complete gutting.
Approved waterproofing systems: Mapei, Ardex, GCP (formerly Grace), and Davco are the main systems used by NZ tilers. The waterproofing membrane is applied to walls and floor before tiling.
Building inspections: Consented bathroom renovations have a waterproofing inspection stage. Your building inspector will check the membrane is correctly applied before any tiling can cover it.
Plumbing for a New Shower
Installing a new shower in an existing bathroom: - Same location as existing shower: Minimal plumbing — connect to existing rough-in. Plumber fit-off only ($300–$600). - New location in existing bathroom: Relocate drain and water supply — drainlayer required ($1,500–$4,000 extra), plus plumber. - New bathroom or ensuite: Full rough-in plumbing from scratch — drainlayer and plumber together ($4,000–$10,000 for plumbing alone).
Glass Shower Screens
A shower screen separates the wet shower area from the rest of the bathroom. Options:
Frameless glass: No aluminium frame — just glass (10–12mm toughened) with minimal hardware. Premium appearance. Heaviest glass. - Cost: $1,200–$3,500 supply + installation.
Semi-frameless: Glass with a minimal frame on sides only, no frame on door. Popular balance of appearance and cost. - Cost: $800–$2,200.
Fully framed: Aluminium frame on all sides. Most affordable, older style. - Cost: $400–$900.
Sliding vs hinged door: Hinged doors require more clearance but look more premium. Sliding doors suit smaller bathrooms where a swinging door would be awkward.
Getting the Best Quote
For a new shower installation, you'll typically coordinate: 1. Builder — waterproofing substrate (cement board or fibrous plaster), membrane application 2. Plumber — rough-in and fit-off of mixer and drain 3. Tiler — wall and floor tiles 4. Screen installer — glass shower screen (sometimes the tiler installs this too)
Many bathroom renovation companies offer a one-trade-manages-all approach where you deal with one company who subcontracts the trades. This simplifies coordination but may cost 10–20% more than managing trades yourself.

Frequently Asked Questions
How much does it cost to install a shower in NZ? A prefab acrylic shower unit: $1,500–$3,500 all-in. A tiled shower recess (900×900): $4,000–$9,000. A tiled walk-in shower (1200×900): $6,000–$14,000. These prices include plumbing fit-off but not tile supply — see tiling cost guide for tile material pricing.
Do I need building consent to replace a shower in NZ? Like-for-like replacement (same position, same configuration): generally not required. New shower in a new location, or any work involving moving drain pipes: building consent required and drainlayer for the drain work. Confirm with your local council.
How long does shower installation take in NZ? A prefab unit: 1–2 days. A fully tiled shower recess: 5–10 working days (waterproofing cure time + tiling + grouting). If drain relocation is involved, add 1–3 days for drainlayer work before the builder starts.
What is the best shower waterproofing system in NZ? Mapei, Ardex, and Davco are the main systems used by NZ tilers — all are reputable when applied correctly. The quality of the application matters more than the brand. Ensure the membrane is applied to manufacturer specifications (correct thickness, correct overlaps) and confirmed by a building inspector if the work is consented.
Can I have a walk-in shower without a screen in NZ? Yes — an open walk-in shower with no screen or door is practical if the shower area is large enough (1200mm+ from the wet area to where you step out) and the floor fall is designed correctly. A drainage channel (linear drain) flush with the floor is the standard solution, directing water away from the exit.
