I used this pre-made shower pan and waterproofing kit for the first time and liked it.
I do about 10-15 mud set tile showers a year and generally build my pan from scratch with pan liner and mortar, then I use hardi backer brand concrete board on the walls, then I tape and mud all seams followed by 3 coats of Redguard. That process takes 3 days always because of cure times. I prepped a 4' x 3.5' shower with 9' walls in one long day the first time I used this system. I put the pan in, hung the concrete board, and put on all the waterproofing on the first day and started setting tile the following day. Obviously this is a big time saver and will go faster the next time I use this system. The one tricky part is hooking up the drain. My job was a second floor bathroom remodel with no access to the drain pipe from below, so I had to make the glue connection as I set the pan. That just made it a bit more challenging the first time out. Setting the pan and drain first and then making the drain connection later is definitely the easier way to go if possible.
