Hi all,

I am installing a new shower kit in our little bathroom. Here is the kit I bought:

http://www.menards.com/main/pl...p-1451539-c-8358.htm

The instructions don't call for any anchoring of the base. You're just supposed to to put it down and then install the panels around it against the wall on top of the base. Apparently, hat's supposed to hold the base in place sufficiently.

However, the base is a little unlevel and I'd like to straighten it by screwing it to the floor and the walls. My questions are these:

What screws should I use? They will go through the plastic material of the base, then through a thin layer of self leveling concrete and finally into the plywood subfloor.

How do I best seal the screws so that there is no chance they'll get exposed to water? The ones I'll be putting into the side will be covered by the side panels of the shower kit so there's no way they'll get in touch with water but I'm concerned about the ones going into the floor. How can I effectively seal them? Note that I am not planning to put them directly through the base in the area where the water is flowing. Rather, there are little circular indents in the front underneath of where the door will go so they'll be out of the way of direct water streams.

Thanks for any answers!

Follow the instructions. If the surround sides are attached to the walls and the surround sides are also attached and overlapping the base, they will hold the base in place. If you subfloor is not level then make it level prior to installing the shower. If the base is set on a level surface and the wall surround pieces are attached correctly then the base is going nowhere.

If you really feel paranoid about the base moving, you could get away with installing some screws through the upper part of the lip that goes up under the side surround pieces. Just screw into the studs and seal the heads with silicon.

Again - If it's designed to be installed without screws in the base then do it as instructed. Do NOT put any screws in any part of the base except the upper lip.

well, let's see here. you get a waterproof shower base to hold the water flowing towards the drain, and then you slam in a bunch of screws through the base to break that waterproofing.

fail.

the way these things generally work is you have screw holes in the lip (slots actually to allow movement instead of cracking), over which the next piece slips, with perhaps a bit of caulk to insure no splash-up of water to leak.

read the instructions, look at the pan to make sure it has structure to contact the floor and support it. if not, they will tell you to slop down some mortar or foam.

Well, let's see here:

I appreciate you taking the time to write a reply but how about you actually read the original post before replying next time? And if you did read it and what you wrote is the reply that you came up with then you may want to work on your reading comprehension.
