New to forum, but I've browsing this site for some time for proper instructions, but it's time to get down. Very good information on this site. Things make a lot more sense after reading some of these threads.
I have never build a shower pan before, so I need help. Now the question? The bathroom basement has concrete floor, can I start with building the slope right from there or do I need something in between concrete. Also I built a knee wall, will that affect mudding the curb? Anything will help. Thank you in advance. Gracie

The dry-pack for the shower floor (the pre-slope, if you need one) needs to be bonded to the concrete with thinset. A thin coat will be fine.

As far as the knee wall, I'm not sure I understand the question. Do you see some potential problem with this?

will you be using a schluter drain and Kerdi pan or the conventional pre-slope/liner/mortarbed?

The knee wall will be covered with durock, so I guess that will be ok. Looks like the plumber installed a regular pvc pipe with a 2" drain. I have been looking at he Kerdi drains, but the drain was already there when we moved in.

I am trying the conventional pre-slope/liner/mortarbed..keeping fingers crossed!

OK, good luck. The is no reason you couldn't switch to a Kerdi shower. Just break the floor, a 5-6" hole is plenty. cut the pipe and go Kerdi.

What are you using as a substrate on the walls? Will they be Durock too? Using a surface waterproofing or not? You got the curb figured out? Lots of nice articles on this site, Harry spent lots of time getting you the info.

All interior will be durock. Not sure on waterproof, saw the article on Lacrete, but the Kerdi membranes looks like a winner.

Kerdi is the only way to go for showers. http://picasaweb.google.com/tile4youinc

Wow nice work!...Again i'm new at this, but the space i have is 36"Wx64"L. How much material will cover the base for pre slope and bed.

Hi Gracie, go to Home Depot and get 5 bags of sand mix and follow Harrys' instructions to the tee . Whatever unopened bags are left HD will take them back. Hope you have a truck - good luck.
