Choosing a tile pattern might seem straightforward, but the layout you pick can dramatically change the look and feel of a room. Two of the most popular options in New Zealand homes are the straight-lay (also called grid or stacked) pattern and the brick-bond (also called offset or running bond) pattern. Understanding the difference will help you make a confident decision before your tiler gets started.
What Is a Straight-Lay Pattern?
A straight-lay pattern arranges tiles in a simple grid, with all horizontal and vertical grout lines running continuously across the surface. Each tile sits directly above and beside its neighbour, creating a clean, uniform look.
- Grout lines are perfectly aligned in both directions
- Works well with square tiles and large-format rectangular tiles
- Creates a modern, minimalist aesthetic
- Easier and faster to lay, which can reduce labour costs
- Ideal for smaller spaces where a busy pattern might feel overwhelming
This layout is very popular in contemporary NZ kitchens and bathrooms, particularly with large-format tiles (600×600 mm and above), where the continuous lines emphasise the tile size.
What Is a Brick-Bond Pattern?
A brick-bond pattern offsets each row of tiles by half a tile length — just like the brickwork on a house. The result is a staggered look where vertical grout lines never line up between rows.
- Each row is offset, typically by 50% (though 33% offsets are also used)
- Adds visual interest and a sense of movement
- Traditionally used with rectangular tiles (e.g. subway tiles)
- Helps disguise minor wall irregularities
- A classic choice for splashbacks, feature walls, and bathroom floors
Subway tiles in a brick-bond layout are a perennial favourite in NZ homes, giving a timeless look that suits both heritage villas and modern builds alike.
Side-by-Side Comparison
| Feature | Straight-Lay | Brick-Bond |
|---|---|---|
| Grout line alignment | Fully aligned (grid) | Staggered (offset) |
| Best tile shape | Square or large-format | Rectangular (e.g. subway) |
| Visual effect | Clean, modern, minimal | Classic, textured, dynamic |
| Installation difficulty | Easier | Slightly more complex |
| Waste factor | Lower | Slightly higher (more cuts) |
| Hides wall imperfections | Less effective | More effective |
| Popular NZ use | Large-format floor/wall tiles | Splashbacks, bathroom walls |
The 33% vs 50% Offset — Does It Matter?
With brick-bond, the standard offset is 50% (half a tile). However, many tilers and tile manufacturers recommend a maximum offset of 33% for tiles longer than about 400 mm. This is because a 50% offset on long, narrow tiles can cause the edges to lippage — where one tile edge sits slightly higher than the next — especially on walls that aren't perfectly flat.
BRANZ research and industry best practice both highlight lippage as a common tiling defect. If you're using longer rectangular tiles, ask your tiler about using a 33% offset to reduce this risk.
Grout Joint Width: What the NZ Building Code Says
Regardless of pattern, grout joint width matters — especially in wet areas like bathrooms and showers, which fall under Clause E3 of the NZ Building Code. Grout joints must be properly filled and sealed to prevent moisture ingress.
- Rectified tiles (precision-cut) can use narrower grout joints (as little as 2–3 mm)
- Non-rectified tiles typically need wider joints (3–5 mm or more) to accommodate size variation
- In wet areas, use a waterproof grout or apply a grout sealer
For wet area waterproofing requirements, refer to guidance from MBIE Building Performance.
Which Pattern Is Right for Your Space?
Go with straight-lay if you want to:
- Emphasise large-format tiles
- Create a sleek, contemporary look
- Keep costs down (less cutting, less waste)
- Tile a smaller room without adding visual complexity
Go with brick-bond if you want to:
- Add character and a sense of movement
- Use classic subway or metro tiles
- Soften the look of a long, narrow space
- Disguise slightly uneven walls
Tile and Adhesive Choices in NZ
Whichever pattern you choose, using the right adhesive is critical — particularly in wet areas. Products from Ardex and Mapei are widely used by NZ tilers and are formulated for our climate conditions. For tiles, you'll find a broad range at Bunnings and Mitre 10, or through specialist tile suppliers.
When to Call a Professional
While choosing a pattern is a DIY-friendly decision, the actual tiling work — especially in wet areas — is best left to a qualified tiler. Wet area tiling in bathrooms and showers involves waterproofing membranes that must comply with the NZ Building Code. Poorly applied waterproofing is one of the leading causes of costly water damage in NZ homes.
If your project involves any plumbing alterations (moving a shower drain, for example), this is restricted work under the Plumbers, Gasfitters, and Drainlayers Act and must be carried out by a licensed tradesperson registered with the Plumbers Gasfitters & Drainlayers Board.
For everything else, a skilled tiler will ensure your chosen pattern is set out correctly, cuts are minimised, and the finished result looks professional. You can find qualified local tilers on tradedirectory.co.nz.
