Regarding a half-shower door, our dear reader Melissa shares, “My aunt just had one done. She said there are no issues as long as you ensure the contractor puts the appropriate slope on the shower floor.” This is of the utmost importance, especially if you’re installing a half-wall after the initial installation of the shower. If you’re changing the shower basin in any way, make sure the floor is angled so that the water that will inevitably escape has a process to drain to inhibit any unnecessary standing water.
