67 live kitchen sinks, censused 17-10-2026. 67 = 59 in /collections/kitchen-sink + 8 live Aalto sinks listed outside it. The collection holds 88 = 63 active + 7 draft + 18 archived, and 59 = 63 active less 4 sink accessories (a strainer pipe, two drainers and a cup washer). 18 print a mount = 4 + 6 + 8; the other 49 print none.
Every sink that prints a mount is Aalto. The mount sits in the description on all 18, and the 10 inside the collection print it in the title too. Six of the eight Top/Undermount sinks are among the eight listed outside the collection, each on its own product page. Steel thickness splits along the same line: every sink that takes both mounts prints 4mm, and every single-mount sink that prints a figure prints 1.0mm or 1.2mm.

Field order as printed on the 18 live Aalto sinks that print a mount, read 17-10-2026. 17 of the 18 print all five fields; the AT8447 prints the mount and the finish only.
Read the bracket first, since it tells you whether the sink sits on the counter, under it, or either. Then read the cut-out size, which is printed separately from the overall size: the AT6845N prints 680x450x230mm overall and a 530x380mm cut-out. The other 49 live sinks, from NOBEL, G.Ferretti, NTL, Boshsini and the Aalto AT2418 fireclay sink, print their size and material without a mount word.
Where does a kitchen sink listing print its mount?
