Porcelain
Denser and less absorbent than ceramic, which is why it is the usual choice for shower floors and anything that stays wet. Harder to cut.
Walk-in showers, pans, niches and benches, waterproofed before a single tile goes on.
Tell us about the project and we will get back to you.
Tile and grout are not a waterproof layer. The system that keeps water out is buried, and nobody inspects it once the job is done.

Moving a drain, a valve or a supply line is licensed plumbing work in Utah and belongs to a licensed plumber. The tile side, from substrate to final seal, is the tile trade.
Two showers the same size can be very different jobs. These are the things that move the number, and they are the things worth asking any installer about.
The three usual choices behave differently once they are on a wet wall.

Softer and easier to cut, and fine on walls. Chips more readily underfoot, so it is a weaker choice for a shower floor.
Marble and travertine need sealing, and acidic cleaners will etch them. More upkeep than either of the above.
It depends on the size, the tile, the waterproofing system and what the tear-out finds behind the old one. We do not publish a number, because a price that has not seen the room is a guess. Tell us the room and we will come look at it.
Ask which waterproofing system they are using, and ask to see it before the tile goes on. That layer is buried for the life of the shower and it decides whether it leaks. In Utah you can also look up a contractor's license number at the state registry before you hire.
Almost always because the waterproofing behind the tile was skipped or broken, not because the grout failed. Grout is not a waterproof layer. A shower needs a sloped pan, sealed corners and a continuous membrane before any tile is set.
No. Tile needs a flat, sound, waterproofed substrate. Covering a failing one hides the reason it was failing and buys a year or two at most.
Most run three to five working days, because waterproofing and mortar need cure time between stages. A schedule comes with the quote.
