Should You Buy the Tiles or Leave It to the Tiler? Plus How Many to Order

Both approaches are fine. Supplying your own tiles gives you control and the freedom to shop around, but the responsibility for ordering enough, matching the batch, and covering breakages lands on you. Letting the tiler supply them brings trade access, the right overage worked out from the actual setting-out, and one party responsible if anything is short or wrong. Plenty of people choose the tiles themselves for the look and then let the tiler order them, which is often the smartest split. Whichever you pick, the one rule that never changes is to order more than the bare area, all in one batch.

Key takeaways

• Supplying your own tiles gives control but puts ordering and breakage risk on you.
• A tiler supplying tiles brings trade access, correct overage, and clear responsibility.
• Always order extra for cuts, breakages, and future repairs. Never the exact amount.
• Order all of it in one go, same batch, or shade and size differences will show.

Should you buy the tiles, or let the tiler?

There is no single right answer here, only a trade-off between control and responsibility.

Supplying your own tiles gives you full control of the look. You can spend as long as you like choosing, shop around for the design and price you want, and buy exactly what you fell in love with. The catch is that the responsibility comes with them. You order the quantity, you carry the batch-matching risk, and if a few break during the job, sorting replacements is your problem and your delay.

Letting the tiler supply brings trade access, which most tilers have through merchant accounts, and it hands the practical risk to the person best placed to manage it. The tiler works out the overage from the real setting-out, orders one matched batch, and is responsible if the quantity is wrong. You lose a little control of the buying, but you gain a single point of responsibility.

The middle path is what a lot of people land on. Choose the tiles yourself for the design, confirm them, then have the tiler order them. You get the look you want and the trade buying, batch matching, and clear responsibility that come with the tiler placing the order. For how this fits into the wider job, see how to prepare for a tiler.

Trade access versus the retail shop

A specialist tiler usually buys through trade merchant accounts rather than a retail tile shop. That can mean better access to ranges, the ability to confirm batch and stock before ordering, and a relationship with the merchant if anything needs replacing. It does not automatically mean a cheaper price to you, and you should never assume it does. The real value of trade supply is less about price and more about getting the right tiles, in the right quantity, in one batch, with someone accountable for it.

If you have found a tile you love at a retailer, that is completely fine. Just be clear on who is ordering, and make sure the overage and the batch are sorted before anything is bought.

How many tiles should I order?

The single most common mistake is ordering the exact floor or wall area and nothing more. You always need extra, and there are three reasons:

• Cuts. Tiles around the edges, around fittings, and at the room’s corners are cut, and the offcuts are usually waste. The more complex the shape of the room, the more cutting waste.
• Breakages. Tiles break in handling and laying. It is normal, and you need spares so a cracked tile does not halt the job.
• Future repairs. Always keep a few spare tiles back after the job. If a tile chips or cracks in a few years, you can replace it from the same batch instead of facing a mismatch or a strip-out.

How much extra depends on the room and the layout, which is why I will not put a flat figure on it. A simple straight lay in a square room needs the least. A herringbone, diagonal, or strongly patterned floor needs noticeably more, because the angled cuts generate far more waste. See the tile installation guide for how layout drives the cutting. The honest way to get the overage right is to have the tiler calculate it from the actual setting-out rather than relying on a rule of thumb.

Why batch and shade matching is not optional

Tiles are manufactured in batches, and the shade, the surface, and sometimes the precise size vary slightly between batches. Within one batch they are consistent. Across batches they are not, and the difference shows badly once tiles from two batches sit next to each other on the same wall or floor.

This is why you order everything, including the overage and the spares, in one go from the same batch. It is also why running short partway through a job is a genuine problem and not a quick top-up. If you have to buy more later, you are at the mercy of whatever batch the merchant has in stock, and it may not match. Getting the quantity right the first time is not fussiness. It is the difference between a floor that looks like one floor and one that looks patched.

Get the supply decision right before the job starts

Whether you supply the tiles or I do, the key is settling it clearly before any work begins: who orders, how much overage the setting-out actually needs, and that it all comes from one batch. I am happy to supply through trade or to work with tiles you have chosen yourself, and either way I will work out the correct quantity from the real layout.
