Tile and porcelain

Porcelain is denser and absorbs less water than ceramic, which is exactly why it turns up in bathrooms and entries. But density is only half the job. Lippage, one tile edge sitting proud of its neighbour, comes from the substrate underneath being out of flat, not from the tile itself. The flatter the floor is before a single tile goes down, the tighter and more even the finished surface reads. Grout joint width follows the same logic in reverse: a bigger joint hides more variation in a floor that isn't perfectly flat, a tight joint on large-format tile only looks right over a substrate that has been brought properly level first.

What a bathroom job actually involves

One customer here remodelled a master bath and an upstairs bath at the same time, and staff walked the tile selection with them before either room was touched. They ended up on Italian porcelain, and the master bath alone measured eleven and a half feet by fourteen, enough floor that the setting-out plan matters before the first cut is made. Wet rooms also get movement joints where the floor meets a wall or another surface, and waterproofing behind and beneath the tiled area generally, so the water that gets past the grout line has somewhere safe to go instead of into the subfloor.

Two bathrooms, one job, same customer trusting the showroom to help pick the material both times. That kind of repeat trust inside a single project is the clearest signal we have that people liked what they walked out with the first time.
