What size tile is best for a small NB bathroom to make it look larger?

Large-format tiles in the 12×24-inch range are the best choice for making a small New Brunswick bathroom feel more spacious. Fewer grout lines create a cleaner, more open visual plane that tricks the eye into perceiving more floor area than actually exists.

The logic is straightforward: grout lines visually break up a floor into segments, and more segments make a space feel smaller and busier. A small NB bathroom floor of 40–60 square feet covered in 2×2-inch mosaic tiles will have hundreds of grout lines creating visual clutter, while the same floor covered in 12×24-inch tiles will have a fraction of that — creating a calm, expansive look. The 12×24 format has become the most popular choice for NB bathroom renovations precisely because it works in small spaces without requiring the perfectly level substrates that truly large tiles (24×24 or larger) demand.

Tile orientation matters as much as size. Laying 12×24 tiles with the long edge running parallel to the longest wall in your bathroom creates a sense of length and draws the eye toward the farthest point, making the room feel more expansive. In a narrow NB bathroom — a common layout in the province's older bungalows and split-levels — running the tile lengthwise down the room rather than across it makes a noticeable difference.

Colour and finish amplify the size effect. Light-coloured tiles — soft greys, warm whites, light beiges — reflect more light and make small bathrooms feel airy and open. Pair light tiles with a matching or similar-coloured grout so the grout lines virtually disappear, creating an unbroken visual surface. A contrasting dark grout on light tile does the opposite, emphasizing every joint and making the floor feel busier. Matte or satin finishes are practical for NB bathrooms because they provide better slip resistance than polished tiles when wet, and they hide water spots and soap residue better than high-gloss surfaces.

Practical NB considerations for large-format bathroom tile include subfloor preparation. Larger tiles are less forgiving of subfloor imperfections — any bump or dip in the substrate creates lippage (where one tile edge sits higher than its neighbour), which looks poor and catches toes. Many older NB homes have subfloors that need levelling compound or additional plywood overlay before large-format tiles can be successfully installed. Budget $1–$5 per square foot for subfloor preparation if your home was built before the 1990s.

For very small powder rooms or half-baths under 30 square feet, a 12×12 tile in a light colour with matching grout also works well and is slightly easier to install in tight spaces around toilets and pedestals. The key principle remains the same: minimize visual interruptions across the floor surface.

One common mistake to avoid is choosing tiny mosaic tiles for bathroom floors thinking they look upscale. While mosaics can be stunning as accent strips or in shower floors where the small tiles conform to drain slopes, covering an entire small bathroom floor in mosaic tile creates excessive grout lines that make the space feel cramped, are harder to keep clean, and cost more to install due to the labour-intensive grouting. Save mosaics for accents and use large-format tiles for the main floor area. A professional tile installer can help you plan the layout to maximize the visual impact in your specific bathroom dimensions.
