My wife and I purchased a home in July, and there is a problem with the shower in the master bath. The basin is basically level with the floor and the only thing preventing water from leaking is the door sweep. Unfortunately, this is a poor method of keeping the water inside the shower. Are there any quick fixes that can help me? I have considered reworking the door and glass walls, but that is going to take time to pull everything up and install a cultured marble barrier. Thanks for the help
