Shower pan on concrete floor
Hi All:

When you are installing a custom shower pan on a concrete floor, I have heard two different methods:

1. Slip sheet (plastic or felt paper), then metal lathe (although I don't know how I'm supposed to staple it to a concrete floor), then mud pre-slope.

2. Slip sheet, then coating of thin-set (for the mud pre-slope to attach to), then mud pre-slope.

What method is best?

Also, for the shower curb, can I use regular 2x4's but protect the bottom one with plastic or something to prevent it from soaking up any moisture from the concrete floor? (Someone told me to never use treated lumber for the shower curb). Or, should it only be made with bricks? I'm trying to avoid bricks because I don't have a way to cut them.

You can always use a Kerdi shower :-)

How to build a shower - Building a shower pan with pre-sloped mortar bed, liner and curb.

This is a tried and true method----using a PVC liner.

You could also use Hydroban by Latacrete---their website has videos and instructions.

I never heard of the method you mentioned---Mike-----

First of all, you can cut brick with a hammer. You won't be the first man in the world to do this.

If I have a basement I want a shower in, my first choice is to cut out the floor and build a curbless shower with the membrane.

My second choice would be with the hydroban and laticrete drain. You can look on the laticrete site for this.

Now that I think about it, a curbless with the laticrete system is good also.
