The snap ins are fine. The question is do you want utility, or looks? If you want utility (plenty of area to get in at the pipes) get the larger of the access panels. The smaller if you'd rather have the looks.

Keep in mind, if the plumbers did their jobs right, this panel should never have to be used.

Mostly I want it. My carprnter didn't even mention it but I got to looking on line and see they are pretty cheap. That wall will be papered and I thought a nice cover would be the thing to do. Easier to do it now than later if I have a problem. OR I change my mind again on where stuff lives.

Bill has it right. The larger is great for plumber access, and I would go with that......but hey, that's just me.

I bought one of everything they had. I'll take the ones back he doesn't use. I thought the 14x14 but he probably won't see things my way. Especiallly since this wasn't his idea. Just saying, he makes everything and I bet he has a plan for access. this would be too easy.

Laz-- the last owner of my house revamped one of the bathrooms and put a 14" panel on the back of the shower wet wall, and it looks crummy as hell. Not that the bathroom is any great masterpiece, but it doesn't look bad, except for that access panel.
