Choosing a shower-floor tile is not a competition to find the roughest surface. A product needs to provide the right wet-use characteristics while remaining realistic for the household to clean and maintain.
Texture changes how residue behaves
Ridges, pores and structured surfaces can hold soap, body oils and cleaning residue differently from a smooth tile. This does not make textured tile wrong. It means the finish should be matched to the cleaning routine and product guidance.
The deeper the relief, the more carefully the surface should be inspected in a sample.
A showroom sample is worth touching
Look at the surface under water, run a cloth across it and consider how a brush will reach the texture. The visual sample should be assessed for feel and maintenance as well as colour.
The same design in a lightly structured matt finish may be easier to live with than a heavily textured version, depending on the room and users.
Drainage is part of cleanability
Standing water leaves more residue, regardless of the tile choice. Falls, waste capacity, grout, corners and the shower screen all influence how the floor dries and how often it needs attention.
The best surface decision is made alongside the drain and floor geometry.
