Specification study. This is the materials list Altesora would specify for this room. Every product in it is real, priced, and orderable. The room has not been photographed — the imagery on our website for this space is a generated concept image, not a record of built work, and it is deliberately not included in this document.

Materials, in build order
Listed from what goes against the substrate to what you finally see. The surface beside each product is where it went, and the option named is the one the SKU and price below refer to.

The figure above is one unit of every priced item, which is a floor rather than an estimate — a real room needs more than one box of tile.
End of schedule — 6 products, priced as of August 17, 2026. A specification, not a quotation; prices and lead times are confirmed at the point of order.
Why it was specified this way
Book-matching means two adjacent slabs are cut from the same block and opened like a book, so the veining mirrors across the seam. It only works if the layout is set before anything is fixed, and if the centre joint lands where the room wants it rather than where the tile happens to run out.
Honed marble is softer than porcelain in both look and behaviour. It wants sealing before grouting and a grout that will not stain the stone, which is why the sealer is part of the specification rather than an afterthought.
