The drain base and the waterproofing decide it, not the grate · review
A 24-inch matte black linear drain in 2 mm 304 stainless, the cheapest here, stating 51 L/min — with no certification on the page and the flange sold separately.
A 2 mm wall of 304 stainless is a figure the Neodrain listings do not give. With the stated 51 L/min, about 13.5 gpm, it is the strongest specification on this shelf.
Certification. No cUPC, which both Neodrain drains state. The flange, which DLONE warns about in its first bullet. And a build height, which decides how the drain meets the tile.
Available at around $49.58 on Amazon.com when we checked on October 29, 2026, for delivery to a US address.

The drain base the channel sits on, which ties it to the 2-inch waste pipe and the shower's waterproofing. DLONE puts it first on the page: it is not included. Buy one that matches your pipe and membrane before tiling.
On a permitted job, it can. Inspectors look for cUPC or a similar listing on drains; the Neodrain drains on this shelf state cUPC and WaterMark. On a straightforward replacement it may not be checked, but the paperwork is what you would show if it were.
DLONE describes a metal matte black process on stainless. Any dark finish on a floor drain shows scale and scratches from grit more than brushed steel. Clean with a soft brush rather than abrasives.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
