I'm hoping there is someone who can direct me to a source for getting basic knowledge about how to purchase shower doors and faucets with a slide bar. I'm planning a Master bath and I'm clueless about how to choose these items. Budget is a concern, and of course, I'd like the best buy on these items. I also saw that Kohler provides a shower base that has a seat incorporated into it. Kohler describes the seat as "plastic" not acrylic. This scars me b/c I'm afraid the "plastic" will oxidate and turn color before long. I'd appreciate any advice you may have. Thanks!
