I am working on a primary bathroom renovation, in planning stages. I will have a tiled shower https://www.msisurfaces.com/porcelain-savoy/crema/ but looking at options for a shower sill. Shower size 66x 42 inches, 2 glass walls, will be in a corner. One piece sills look like they are the best option due to ease of cleaning, less breakage compared to tile, etc.

The tile shop has marmiline https://www.anatolia.com/collections/marmiline an engineered quartz as an option. I have never heard of it. And I did not see it mentioned on any message boards here. Does anyone have experience with this?

I am also getting estimates for a quartz (not marmiline) that the countertop will probably be, I have not finalized this yet as I have not found something I love with my tile yet. But likely Envi marecchia https://www.envisurfaces.com/PHOTOS/MARECCHIA-3CM-QUARTZ-FS.JPG?=10202023a .

But mainly looking for opinions on marmiline or other suggestions on shower sills.
