What is the difference between the T, TS and TT trays?

The T has a center drain. The TS places the drain at the side and the TT at the end, for layouts where the plumbing is not centered.

Do I need the Kerdi Drain with this tray?

Yes. The tray is designed to integrate with the Schluter Kerdi Drain, and the waterproofing relies on that connection.

It is set in thin-set over a sound, flat substrate. Check the technical data sheet for approved substrates and deflection limits before installing.

The tray and the collar. The drain and Kerdi membrane are separate parts.

The perimeter can be trimmed, but keep cuts away from the drain area and follow Schluter's instructions so the slope and waterproofing stay intact.

No. The expanded polystyrene core is light enough for one person to carry and position.
