Laguna Bay 12 in. x 12 in. Cream Ceramic Floor and Wall Tile (14.53 sq. ft. / case)

It's hard to answer this question usefully without more information- what kind of oven, how hot, what you'll be doing with the tile, etc. However, in general, remember that porcelain is fired at very high temperatures, around 2000F and very few ovens go that high. Porcelain must have room to expand at high temps and sudden extreme temperature changes, like an ice cube on a very hot tile, can crack it. The best answer is to point out this tile is very cheap- buy a few pieces and experiment under the conditions you want the tile to perform. Be careful- don't burn yourself and use personal protective equipment.

I would get something with a high gloss. This is pretty matte and will be harder to clean.

It states that each box is 14.53 sq ft. I just went down to 14 sq ft = 1 box 14 sq ft x 13 boxes = 325 sq ft covered. And then two extra boxes. Buy 15 boxes

I've never seen anything but 12 x 12 square and 12 x 3 bullnose and I've probably gone through more Laguna Bay than anyone you know. Remember, anything you can do with 16 x 16, you can do with 12 x 12, although it may take a bit longer. Laguna Bay is such a good value for the $$ that you can afford a bit more time. I just wish they'd come out w/ something a bit smaller- I like to use it for bathrooms in rental units and smaller would be a bit more slip resistant. I notice the description mentions "Ivory." Ignore that- it's cream.

The PEI isn't listed, but if you click on the Specifications, it loads a .pdf which describes classes of abrasion resistance that seem to correspond to the PEI ratings. This tile has a Class 3 rating. Personally, I've used this tile successfully in a slab-on-grade application in rentals, bathrooms, entries and kitchens. I'd prefer a smaller tile size or higher DCOF for bathrooms, but there haven't been any problems so far. If you have a free edge, such as meeting a carpet, I'd recommend a Schluter type aluminum extrusion (available at HD) to protect the edge of the tile.

I think using them both on the floor and the counter tops may be a bit much, but not sure if I saw v-caps when I purchased it. What about one of those cultured marble pieces with the same color palette?

Yes they can. Easy to set up and it’s good work

I've set a lot of Laguna Bay 12x12 tile & I've never see 16x16. At a guess you have something similar, maybe https://www.homedepot.com/p/TrafficMASTER-Island-Sand-Beige-16-in-x-16-in-Ceramic-Floor-and-Wall-Tile-15-5-sq-ft-case-UE4L/202193405?MERCH=REC-_-visuallysimilar_1_0-_-202193314-_-202193405-_-N

If the shower is 8 ft tall and you are going to the ceiling, you will need 8 cases if you have 3 walls. I do not recommend using the 12x12 tile on the floor. It will be slick and increase the chances of a fall. get a 2x2 tile that matches for the floor--25 sq ft. plus sloping toward the drain is a 'bear' with the big tiles.
