Which kit fits a 60-inch tub alcove?

The 38 x 60 kit. Its tray is 60 inches long, matching a standard tub-replacement opening. The 48 x 48 pan is square and needs a square shower footprint.

Which one includes a drain?

The 48 x 48 kit lists a 2-inch PVC drain with a 304 stainless steel grate. The 38 x 60 kit lists an ABS flange but does not name a drain body or grate material.

Is the 48 x 48 worth the extra $130?

If you need a center drain and want the membrane, strip, corners and stainless grate in one box, yes. If your drain is off-center in a 60-inch alcove, the 38 x 60 kit is the only one of the two that fits.

Can the trays be cut down?

The 48 x 48 kit states it can be cut to size. The 38 x 60 listing does not state a cut-down allowance, so plan the opening around 38 x 60.

Both are bonded waterproofing systems over a foam tray, so life depends on the membrane and tile install, not the kit. The 48 x 48 kit names its tray at 57 psi and its grate as 304 stainless, which is easier to judge up front.
