Ceramic flooring looks like a commodity. Two suppliers stock what appears to be the same 24×24 porcelain tile in the same color, at prices that differ by twenty cents per square foot. The temptation is to pick the cheaper one and move on.
That approach works perhaps half the time. The other half, the savings disappear within weeks through one of several mechanisms that the price tag does not disclose. Here is what to look for instead.
1. They publish PEI ratings on every product page
The PEI rating tells you how much foot traffic a tile can handle before its glaze shows wear. Class 1 is for walls only. Class 5 handles commercial spaces. A residential bathroom floor needs at least Class 3.
Serious ceramic floor suppliers list this rating on every floor product they sell. The number sits in the product specifications, not buried in a downloadable PDF. Suppliers who hide PEI ratings or simply do not include them either do not know the rating themselves or are selling tiles whose rating would discourage the sale. Neither possibility is reassuring.
2. They differentiate between rectified and pressed edges
Rectified tiles have edges cut precisely at ninety degrees after firing, allowing grout joints as narrow as one-sixteenth of an inch. Pressed tiles have slightly rounded edges and need wider grout joints, typically three-sixteenths or more.
This distinction matters because it determines the installed look. A rectified large-format tile creates the seamless modern appearance most homeowners want when they shop large format. A pressed tile of the same dimensions, installed with the wider grout joints it requires, produces a noticeably different result. Suppliers who do not flag this difference clearly in their product listings tend to disappoint customers at installation.
A good ceramic floor supplier will not only mention rectified versus pressed in the specifications, but will also show photos of both joint widths so the choice is informed before the order is placed.
3. They stock matching wall tiles and accessories from the same series
Tile manufacturers like Marazzi, Florim, and various Italian and Spanish producers release products in coordinated series. A series typically includes a floor tile, a matching wall tile in a different size, a mosaic for shower floors, and trim pieces. Buying piecemeal from suppliers who only stock the floor and not the rest of the series creates a renovation with mismatched grout lines and a fragmented look.
A supplier who carries entire series demonstrates a serious commitment to the tile category. They have negotiated stock allocations across multiple SKUs from each manufacturer, which only happens when ceramics represent a meaningful part of their business rather than a sideline.
4. Pricing is per square foot, not per box
This sounds like a minor distinction. It is not. Pricing per box hides the variable each homeowner actually cares about, which is the cost to cover their specific space. Two different tile sizes from the same series may have wildly different per-box prices simply because the boxes contain different numbers of pieces.
Suppliers who lead with per-square-foot pricing make comparison shopping honest. Suppliers who lead with per-box pricing are usually hoping you do not do the math. The math, when done, often reveals that the cheaper-per-box option is the more expensive-per-square-foot option.
5. They sell the right thinset alongside the tile
Large-format tiles need medium-bed mortar, not regular thinset. Glass mosaics need non-sag white thinset. Porcelain needs a polymer-modified formulation. Heated floors need a flexible thinset rated for thermal cycling.
A supplier who stocks ceramics but pushes you to buy thinset at a separate big-box store is missing a critical part of the sale. They know the tile needs a specific mortar. They are letting the customer figure it out alone, with predictable results. Brands like Mapei and Laticrete make the right products for each application, and serious tile suppliers stock those alongside the tile they are selling, with clear guidance on which combinations work.
6. The return policy makes sense for tile specifically
Most retailers have a generic return policy that applies to everything they sell. Tile needs something different. Unopened full boxes should be returnable. Partial boxes typically cannot be resold and are usually non-returnable. Cut tiles, even if unused, cannot return either.
Suppliers who address this directly with a tile-specific return policy show that they have thought about how this product actually moves through the customer cycle. Suppliers who have only a generic ninety-day return policy on everything either get burned regularly on partial-box returns, which raises their prices, or they refuse the partial boxes anyway and create unhappy customers at the moment of return. Neither situation favors the buyer.
Three red flags worth walking away from
The first red flag is missing manufacturer attribution. Tile listed as simply “porcelain 24×24 gray” with no manufacturer name suggests either grey-market imports or product the supplier cannot identify themselves. Warranty claims become impossible.
The second red flag is unavailability of physical samples. A supplier who cannot provide a small sample tile or a piece of the actual production run before a large order is one whose product photography is doing the heavy lifting. Tile color and texture differ from photos more than almost any other building material, and committing to two hundred square feet based on a screen image regularly produces buyer’s remorse.
The third red flag is pressure on dye lot timing. Suppliers who push customers to order immediately because “this dye lot is leaving” or “the price goes up next week” are using techniques designed to bypass careful consideration. Serious tile suppliers know that their customer is choosing a permanent surface for their home, and they support the timeline that requires.
The cost of choosing wrong
A bathroom renovation involves perhaps two hundred dollars of tile, sometimes more for a primary bathroom with large-format porcelain. Choosing the wrong supplier rarely shows up as a problem at the purchase stage. It shows up six months later, when the warranty claim has nowhere to go because the manufacturer was never properly identified, when the replacement tile is from a different dye lot than the original installation, when the thinset that came from a different store has failed under thermal stress, when the partial box that was supposed to be returnable is sitting in the garage gathering dust because the return window expired during the contractor delay.
The good suppliers are not always the cheapest at the moment of purchase. They are almost always the cheapest by the end of the project, once all the hidden costs of the alternative get tallied honestly.
