Thanks dr9164 for your interest.
This liner was manufactured by Plastimayd.
The liner pattern is a mixture of the patterns they offer.
Here is a link to their site:

It was a mixture of the Carrara base and the Augusta Tile line.
There is also a special gray "textured" material on the stairs and sunning deck area.
The "tex tread" material is a thicker vinyl that also has a slip resistant texture.
