Best Drain Choice for a Solid Stone Shower Base (Made in Indonesia)

Ok - another tuff question for the day. I looked at this job tonight and it has a solid stone slab (one piece) and the shower slope and drain prep has been machined into it. The shower has no resin backing and no drain.

No instructions.

No Warranty.

Of course I said it would be easy to install.... lol What type of drain would work best with the milled opening. Roughly 1/4" deep and just a hair wider than 5"

Please god don't let the Kerdi Salesman Chime in and tell us something he learned a minute ago. It would be great to here from Terry, Roberto or Counter Balance on this bad boy. It might be some kind of soapstone ???

 

Anyone?

I send and email out to the Brass at OS&B. Hoping Bob knows something. Had a nice chat with him yesterday and he is going to send me out one of those new freestanding tub drain thingings that I missed the Product Training Class on.

Tells me that they are working on a flange adapter for it as well so it can be tied into NobleSeal CIS or NobleSeal TS for large barrier free showers.

I like a lot of the OS&B stuff. Especially their cheap ABS clamping drain. Works perfect for my ACO linear shower drain installs tight to the wall! Ssssh don't tell ACO

 

John , just use a drain made for cast or acrylic shower receptors. Like this one , for example .

Here is a stone receptor from a project I've worked on .

Just adding ........ Those small drainage channels -- rough stone -- could benefit a treatment of enhancer sealer . It will make the water slide of them and clean up an easy task .

 

John, looks just like the wedi drain connection. And similar to that prefab kohler fiberglass insert with the linear strainer/grate?

Heres what i use on the wedi connections...

heres a wedi connection under flood...

 

That Wedi drain does look like a winner. Do you know off the top of your head what the drain grate looks like and how wide the grate is. I'm looking for 5" ideally.

Roberto that Kohler drain is just 4 3/8" wide... Thanks though

 

Did not find the size of the Wedi Drain anywhere online but notice that all the covers are square... I need a round one. 5" O.D.

 

The wedi is a 4" strainer and square.......and a strange system. it actually is a floating strainer body & grate that gets set in the grout itself if it is not on the adapter extention its is just set in the grout and resting on the pans divot edges.

Could you use the Wedi "type" connection ( their wedi drain kit comes with a larger bottom flange gasket and nut that may be a good support under that pan ).........and customize say a zurn 5" grate to fit????

Thats a tough one. 5"

5" zurn ( i realize it has screws and a body??)

John ,
If I could make a custom linear grate , I am pretty sure you can just make a cover grate -- 5'' -- which can fit any type of the existing receptors drains . You can design a JFW on the cover grate , a nice one .

 

Similar to this .....

 

I like the custom work Roberto. My birthday is just around the corner.....



That's the zurn drain. This might work.... Thanks men.

 

A pop up drain ? These look pretty nice .....@ 5'' diameter .

Nice Roberto. I think the plan is this.

Just pretend that the stone is waterproof.

Plan that it is not.

NobleSeal CIS the bottom of the subfloor. Set the stone base to it with Ardex 8+9.

Jerry rig a drain to the CIS.

Later ad in something like you show overtop as a grate so it looks nice.

Going to hit EMCO and B&G on Monday for any more inspiration. One thing that I like about this pickle I'm in on this job is that there will be no city inspectors looking over my shoulder.

Time to go


CowBoy.

The other option is for them to maybe return the stone to Indonesia and just waste the $1,000.00. Like that is going to happen.

We have a dream environment that the showers drain (bottom side ) is inside the front hall closet. We will be able to monitor the connection and check for leaks.

Maybe I could install the Hydro Ban Bonding Flange over the drain location. Tie in my NobleSeal CIS to that.....

hmmm

Jerry Rig that sexy round drain you found in the open position and silicone the bitch over top!

 

Roberto it looks like there is all ready some kind of sealer on this shower base. I flipped it yesterday and preped for some NobleSeal CIS. Used my diamond scouring brick and could "Feel" a resin of sorts. Gave the underside a good scrubbing to remove the filth that was stuck to the bottom.

Had to clean the back side six times (30 minutes of work) before I had a clean rag. Can you say bond breaker?

Once clean and air dried. I tapped the edges and gave it a burn coat of Ardex 8+9. Today I'll install the NobleSeal CIS to the base with more Ardex 8+9. Going to Jerry Rig and OS&B 2" ABS clamping drain to the bottom. I'm just not going to use the clamping top and bolts.

 

A few pictures of the work yesterday from my blog post.

This shower base is a beast. Easy 300 pounds I think.

Cleaned of the factory seconds off the bottom with that brick.


More photos here

Nicely roughed up.


More photos here

Not one bucket. Not two. Not three. Or four, five but six buckets of water before the bottom was clean.

Once dry the Ardex 8+9 went on - first coat....

 

Did you make a water test on the pan ? If the drainage channels change color -- darken -- when wet , it means that no sealer is present . The use of the enhancer was only for the channels -- bring them to look the same as the honned stone -- , then seal them with a good sealer -- not an enhancer -- so the stone stays as is -- color wise -- .

Maybe the stone will also benefit from 8+9 on the vertical sides -- exterior ones -- which are hidden .

 

I did not water test the top side of the pan. Look at the other pictures Roberto. I check that the back side was absorbing some liquid. Before I used the 8+9.

I worry that the sides will not accept the 8+9 very well. I'm going to set those with NobleSealant 150 I think and a tiny V-Notch trowel. I might even skip sealing them the the sides anyway. The base goes in tight to the framing. I might eat away a little wood - tape with Mapeiband and then set the NobleSeal CIS to the sides with 8+9 (outside not inside).... Crazy I know.

I'm going to do a shear test on the side before I go forward. Look for any reaction from the NobleSealant 150 or 8+9 before touching the finished sides.

In un-charted territory here!

 

Why the sides will not accept 8+9 ? Just paint -- roll the sides -- only the hidden ones.

 

Not sure. Just a hunch. Their is like a glaze over the top and sides. I think solvent based.

 

Found an American Supplier of Stone Shower Bases.

Interesting conversation with their sales girl.

Take a look.
