Insane in the Membrane
The shower “membrane”, that is. After your shower pre-slope is fully dried— you waited 48 hours, right?— you can place the shower liner in and do your final pour of shower mix (sand and cement mixture). Then it’s smooth sailing. Honestly, don’t skip the pre-slope! Without it, your water will sit and mold will grow below your shower’s surface. Ewww, nobody’s got time for that.
