It really isn't a big deal to bust up tiles in Thailand. They rarely even use a thin-set type adhesive like most western countries.
Cement/sand mix is used both to level the tile area and secure the tile in place, all in one go.
They do sell the adhesive, and some will use it on walls/verticals/small accent tile pieces etc... But mostly just cement & sand.
Messy, yes, but piss easy.
Any ole farmer type & his wife can do it for 300/day barely supervised from start to fully supervised cleanup.
