Water pooling in swanstone shower base
We are in the process of renovating our atatched bathroom and choose to go with swanstone showerbase, which actually costs us more over a simple tiled floor and wall. During installation, contractor choose not use any cements like material as base but rather choose some sort of mastic glue to fix it atop dual layers of 3/4 inch plywood base. The base, going by the borders, are perfectly level as he showed it to me today. However, after using the shower, there is always a pool of water standing the base. And the water stays on overnight with no sight of draining.
So question is, who's fault it is? manufacturer's or contractor's?
Importantly, how we can now mitigate the problem?
