In reality, the choice affects far more than the finished look of the room. Tile size influences proportion, maintenance, installation, drainage, and how every other feature in the bathroom comes together. The dimensions printed on the box are only the beginning.

Every Bathroom Is Different

One of the biggest misconceptions is that larger tiles automatically create a more luxurious bathroom.

Sometimes they do. Sometimes they don’t.

We’re currently preparing an en-suite where the homeowners have chosen beautiful 1,200 × 600mm porcelain tiles, installed vertically from floor to ceiling. They’re exactly the right style for the room—but only if the room is prepared correctly.

Rather than accepting awkward cuts that would interrupt the clean, contemporary look, we’ve adjusted the finished ceiling height and floor level so two full tile courses sit naturally from floor to ceiling.

Most people walking into the finished bathroom will never notice why the room feels balanced. They’ll simply notice that it does. That’s often the difference thoughtful planning makes.

Sometimes a Smaller Tile Is the Better Choice

Changing the room isn’t always the right solution. Perhaps the ceiling height needs to stay exactly as it is. Maybe the budget is better spent elsewhere, or the character of the property should remain untouched.

In those situations, we’ll often revisit the tile selection instead.

A 1,000 × 500mm, 900 × 600mm or 600 × 600mm tile may suit the proportions of the room far better than a larger format. It may align more naturally with the shower niche, window, basin or bath, creating a cleaner and more balanced finish.

Choosing a smaller tile isn’t a compromise. It’s often the better design decision. Luxury isn’t defined by choosing the biggest tile. It’s found in proportion, careful planning and the feeling that every element belongs exactly where it is.

Why Homeowners Love Large Format Tiles

Large-format tiles remain one of the most popular choices for modern bathrooms, and for good reason. Their generous size creates a cleaner appearance with fewer grout joints, allowing natural stone effects, soft veining and contemporary finishes to become the focus.

They’re also easier to maintain. Fewer grout lines mean fewer places for soap residue, limescale and moisture to build up, making day-to-day cleaning simpler. Large-format tiles do, however, demand more from the installation.

Walls and floors must be properly prepared, layouts carefully planned and every tile accurately positioned to achieve the seamless finish homeowners expect. The simplicity you see in the finished bathroom often comes from a great deal of planning behind the scenes.

When Smaller Tiles Are the Better Choice

Smaller tiles create a very different feel.

Metro tiles, mosaics, hexagons and smaller-format porcelain tiles bring rhythm, texture and personality to a bathroom in ways that large tiles simply can’t.

They’re also particularly useful in shower areas, where the floor needs carefully formed falls to guide water towards the waste. Smaller tiles naturally follow these gradients while providing additional reassurance underfoot through more frequent grout joints.

That doesn’t automatically make them the right choice everywhere. More grout means more maintenance, so it’s often worth considering where smaller tiles will have the greatest impact.

Many of the most successful bathrooms combine both formats. Large tiles may create calm, uninterrupted walls, while smaller tiles introduce detail inside a shower niche, on the shower floor or as a feature behind the basin.

It’s Often the Small Details That Matter Most

Shower niches have become one of the defining features of modern bathrooms. They’re practical, keeping bottles neatly out of the way, but they also offer an opportunity to introduce texture or contrast without overwhelming the room.

Planning matters here too. Will the niche align neatly with the tile layout? Can the shelves comfortably hold the products you actually use?

How will the edges be finished? These aren’t decisions most homeowners think about until someone points them out. Yet they’re often the details that make a bathroom feel considered rather than simply installed.

Craftsmanship You Never Notice

One completed bathroom will always stay with us. The client had chosen white hexagonal mosaics to cover almost every surface—walls, floor, window reveals and the boxing around the concealed cistern.

The tiles arrived on mesh-backed sheets, but the spacing between the sheets wasn’t quite consistent enough. Rather than accepting uneven joints, every sheet was adjusted by hand before installation. There were well over 350 sheets. Eventually, we stopped counting.

Once finished, no one would ever know how much work had gone into creating that seamless honeycomb pattern. That’s often how good preparation works. When it’s done properly, it’s almost invisible.

What You Don’t See Matters Just As Much

Naturally, homeowners spend time choosing the tiles they’ll see every day. We spend just as much time thinking about everything they’ll never see.

Whenever possible, we prefer to strip a bathroom back to its original structure before starting again. That allows us to inspect the walls, update plumbing where required, prepare the surfaces correctly and ensure the new installation has the strongest possible foundation.

Much of this work disappears once the bathroom is complete. But it’s often the reason the finished room still looks and performs beautifully many years later.

Large or Small? Ask a Different Question

Large bathroom tiles can create continuity, fewer grout joints and a beautifully modern finish. Smaller tiles introduce detail, texture and flexibility.

Both can look stunning. The more useful question isn’t “Which tile is best?” It’s: “Which tile is right for this room?” Every bathroom has its own proportions, challenges and opportunities.

The best results come from choosing a tile that complements the space, works with the layout and supports the way you’ll use the room every day.

A Thought Before You Decide

Before choosing your bathroom tiles, don’t ask which size is most popular. Ask which size is right for your room. A tile that looks perfect in a showroom may feel completely different once it’s reaches your home.

The best bathrooms aren’t designed around trends or the dimensions printed on a tile box. They’re designed around proportion, light, careful planning and the people who’ll enjoy the space every day.

Beautiful bathrooms aren’t created by following trends. They’re created by making the right decisions for the room, the home, and the people who use them.
