Unless you're doing all the cuts at once.... just buy a $200 wet saw, take your time, then stash it away or sell it imo... renting would cost me more.... I am slow  . I use Mapei thinset... never any issues. Use regular grout.... don't even think about epoxy crap in tubes.... btdt (royal PITA)... never again. Just my experiences.... good luck!

1/2" back board is used to match the exact thickness of adjacent drywall to create a flush transition. This is where backer boards are screwed direly onto bare stud walls. We don't use too much 1/4" due to it flexing too much. I like the solid thud when you go inside to wash up and punch the wall after half day of swearing, trying get that water pump off your car
