The drain base and the waterproofing decide it, not the grate · review
A 24-inch AISI 304 linear drain, cUPC and WaterMark certified, with a stated 50.5 L/min flow, a 2-inch outlet for a US no-hub drain base sold separately.
cUPC is what a US plumbing inspector looks for on a drain. Neodrain states it, along with Australia’s WaterMark. The DLONE on this shelf states neither.
50.5 L/min is about 13.3 gpm, several times what a shower head delivers. It is measured without the strainer.
The channel sits on a 2-inch drain base that is not in the box, PVC or ABS to match your line. And it has to tie into the shower’s waterproofing; Neodrain says plainly it does not suit the Schluter Kerdi system.
Available at around $51.99 on Amazon.com when we checked on October 29, 2026, for delivery to a US address.

Yes, with a large margin. A shower head is limited to 2.5 gpm federally and 1.8 gpm in several states; even two heads together are well under the 50.5 L/min, about 13.3 gpm, stated here. The figure is measured without the hair strainer, which slows it a little.
A 2-inch drain base, PVC or ABS to match your pipe, which Neodrain sells separately, and a waterproofing system the drain is compatible with. The listing excludes the Schluter Kerdi kit.
Below the floor, in the drain line, as in any American shower. The channel itself holds no water seal.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.
