The shower walls seemed a bit light duty until it was fully adhered to the walls. I seriously don't care for the 4 piece walls, and the aluminum straps to seal them up.

installation issues

No instructions provided for the doors, no identification for the rails, what's top, side? How are they fitted together?

The item is poorly represented in the online images. It is comprised mainly of 4 thin panels that use a (not included) adhesive to stick to the walls. All 4 in ours were cracked on the same corner and that we assume was from shipping. Then there are "trim" pieces for the corners, and the joint that is in the center of what makes up the back panel. This gives it a very "cheap" appearance as opposed to the pictures. The shelves that are pictured are just large enough to place one normal sized bottle on, so I don't know what kind of bottles are in the picture. We went and bought separate shelves and didn't use the ones that came with it. The base is fine and the doors are fine. If you're looking for a high quality appearance, this isn't it.

nice

The shower itself is lovely. Modern clean lines. It also looks like it will be easy to clean. Installation was a bit challenging. Shower doors keep sliding, but this could be the fault of the contractor.
