We have a small bathroom and this unit was a great replacement for our 32” square shower enclosure. The assembly went smoothly. The side walls are secured to the house by screws at the juncture of the dot framing. It has not been a problem but surprising at the lack of attach points. The glass pieces weigh about 40 pounds each. The instructions for the base install calls for cement and I would recommend it. I think there would be soft spots in the shower floor without it.
