The planks didn’t always snap perfectly into one another so some planks have a very thin seam showing between them while others are completely flush and look like a solid surface. They also don’t all lay completely flat on the floor when they’re locked in. It was very frustrating to put together in a small bathroom.  The water proofing looks solid though. 
Wouldn’t recommend for anyone with wall tile in the bathroom, as you won’t have a baseboard to hide the gaps on the edges.
