This is not easy for a novice to put in, but we contacted the company twice during our installation and they took time to speak with us on the phone, offering advice and suggestions that were really helpful and not in the YouTube videos! And we found out if we messed a wall up, we could purchase a separate wall piece... luckily that didn't happen. We did not put the set in shelf/box in as it's too large for our small shower, however we will be putting up the corner shelves in the future. Still, it's lovely and functional.
