Yeah, the waterproofing isn't necessarily hugely labor intensive in terms of hours of active work. And to some extent I was conflating labor and consumables for the surround. So if you've already separately budgeted for the $5-600 or so for the board, sealant, and membrane, and then the mortar costs and whatnot, then that would change things and $2K would be a bit more reasonable (though I still think it'd be low).

The issue is, with smaller jobs like a single bathroom there are still the same number of steps and waiting periods as there are with bigger spaces. For instance, waterproofing the shower with that system involves 2 coats of liquid applied membrane on the joints, but each can take several hours to cure (and sometimes overnight). So just the surround has to get split over at least 3 (and maybe 4) days. And the floor is similar where there are several steps with cure time between them. So your 140 sq ft. bathroom might be 4-5 days of work, which is probably how long it'd take to do an open living space 5x that size. So the per square foot pricing on a bathroom with a tub surround can get pretty eye watering, but it's because the progress is a lot slower.
