Choose tile if the room is wet, sits over radiant heat, or needs to survive decades without a second thought — nothing here beats porcelain's water resistance or its near-permanence. Choose hardwood if the room stays dry and comfort underfoot matters more to you than being indestructible.

The points that decide this in practice — not the spec sheet items that read well but rarely change anyone's mind.
Solid hardwood rates the lowest water score on this site and cups or buckles once moisture reaches the wood — it is explicitly excluded from bathrooms, basements and any below-grade installation. Porcelain rates the maximum, with water absorption at or below 0.5%, dense enough to be frost-proof. This single fact settles most bathroom and kitchen questions before comfort ever enters the conversation.
Porcelain rates the lowest comfort score of any material on this site — genuinely the hardest, coldest surface available, and rooms where comfort underfoot is a priority are listed among the places to avoid it. Hardwood rates in the middle: real warmth and give compared to stone or ceramic, without being soft.
Solid hardwood's own specification names radiant heat as a reason to choose engineered wood instead — the wood moves too much as the subfloor cycles warm. Porcelain is named on this site as the best thermal conductor of any floor, delivering more heat into the room than any other surface, which is what makes a heated tile floor in a bathroom worth the cost.
Both carry the same top-end life expectancy on this site, and the mechanism could not be more different. Hardwood wears at the surface and is sanded back flat five to eight times over its life. Porcelain doesn’t wear at the surface in any comparable way — the ongoing task is the grout, which needs resealing every one to two years in a wet room, not the tile itself.
$9.00–$22.00 per sq ft installed, lasting 50–100 years — about $0.21 per sq ft per year.
Wide planks (6"+) look current but move more seasonally. In a dry climate, expect visible winter gaps unless you humidify.
$8.00–$29.00 per sq ft installed, lasting 50–100 years — about $0.25 per sq ft per year.
The tile is rarely the expensive part. Substrate prep, uncoupling membrane and skilled labor are — and skimping on those is what causes the cracks people blame on the tile. On wood-look plank, put two more questions to any bid: what offset, and what grout joint. A 50% brick-set on a 48" plank with a 1/16" joint will generate lippage complaints no matter how good the tile is.
Tile, specifically because of the dishwasher and the sink, not because hardwood looks wrong there. The room guide for kitchens on this site lists solid hardwood among what to avoid for exactly that reason — water finds the space under an appliance long before anyone notices, and hardwood can’t recover from it the way porcelain can.
Yes, with the right preparation — an uncoupling membrane between the tile and the subfloor is standard practice, and the subfloor needs enough stiffness (deflection no worse than L/360) to keep the tile from cracking. Putting solid hardwood over a concrete slab is the harder direction and normally needs a built-up plywood subfloor system, or a switch to engineered wood instead.
Tile, by a wide margin, unless it is heated. Porcelain's own strength — being the best thermal conductor of any floor — cuts both ways: unheated, it reads as cold as the slab beneath it; heated, it delivers more warmth into the room than anything else on this site.
