Shower Stalls

Standstrong

I am putting in a commercial shower on a new concrete floor.

One guy is telling me I need to put a liner down before I can tile it.

I have done it both ways previously. No problems either way.
Just wondering if ya'll have a strong opinion one way or another.

I would rather cut the cost of the liner and just put it down on the crete.
Please advise.

.....and what exactly is going to waterproof this installation and gaurantee it to be long-lasting and liability-free to you?

What are the walls made of?
How big is this shower?
What makes it a "commercial" installation?
Is a floor drain in place?

How can anybody offer any information if you don't?

As Bud said, more info, but yes, it needs to be waterproofed one way or the other, alot of large commercial floors here are waterproofed with laticrete's 9235 over a sloped mud bed.

boy I knew I would hear it for this one..

Floor drain is to be roughed in prior. It is a campground facility. 36 wide by 60 long roll in shower. ada.

I am to demo the floor and replace it all. my plumber is roughing everything.

The last one I did, I glued epdm 40 mil over the sloped mortar I installed and glued the epdm to the inside of the drain, I brought that epdm up about 8 inches on the wall)...
then put another layer of thinset over that and installed.
I believe, but I cant really remember to be honest.

I know I used keralastic in the grout and it is holding up well.

Walls are to be cement board all the way up. drywall painted for the ceiling with a vent. My drywaller told me that the green board shouldnlt be used for the ceiling. I wasn't aware of that.
8' tile floor 6by8'' for wall

Let me have it

To each his own I suppose. Sounds more like a car wash.

EPDM is a roofing product and used as a pond liner. It is not to my knowledge rated for use in a shower. The product is known to decay from contact with cement products and offers no protection from mold and mildew issues that I know of. EPDM would also be somewhat difficult to dog-ear and make folded corners in my thinking.

There are plenty of recognized shower pan liner products on the market why not use one of them? Try Composeal or Nobles Chloraloy or Schluter's KERDI.

To do this shower properly a liner of some discription would be required. There is also a liquid membrane that would qualify for a shower pan liner under most circumstances. Don't forget the moisture barrier for the walls also.

I am thinking that I will do a shower pan. I haven't used one, would you frame the concrete for it or just drop it in the wet crete?
Which way would you go with the liner.

What type of moisture barrier would you use for the walls?

I also got a quote for some baked enamel partitions. I would like to order those in advance, but I'd hate to paint myself into a corner if the measurements were off.

My partition guy said I needed ADA curtains and rods, I thought that was interesting.

Do you know of a good supplier for the ADA approved bathroom floor tile: I'm not sure what it entails.
Thanks for the help.

Teetorbilt

I just love stirring the pot! I doubt that modern epoxies are entered into the code books as a sealer but I can't think of anything better in this application. It penetrates AND seals.

I have been thinking about what you said teetor. I have brought it up to my tile guy, he questions whether the adhesive/thinset will stick to it after 4 or 5 years. Anyone you know ever try it?
