Do I need both for a Schluter shower?

Yes, if you are building a full Kerdi shower. The drain sets the outlet and flange; the band seals the seams between membrane panels, corners and the floor-to-wall joint.

Which one lasts longer?

Both are designed to last the life of the tile assembly. The band's life depends on full thinset coverage on both sides; the drain's depends on a correct solvent-cement joint and a sealed flange.

Is the KERDI-DRAIN worth the extra over the band?

They are not substitutes, so the comparison does not apply. The drain is $30.22 at Flooring Market and the band is $17.50 at eBay as of November 4, 2026; a shower needs the drain plus band plus membrane.

Can I use Kerdi-Band with a non-Schluter drain?

The band is listed as compatible with Kerdi membranes, Ditra and Kerdi-Board. Sealing to another brand's drain flange is not a listed use.

Does the KERDI-DRAIN come with a grate?

No. The drain body ships alone; buy a 4 in Classic, Contour, Trendline or Tileable grate separately.

What thinset does the band need?

Unmodified thinset, applied so it covers both sides of the fleece. Gaps in coverage are where leaks start.
