Nope, haven't done a floor like that but it sounds totally fabulous!! Love the curbless look and definitely would have liked to do the same but couldn't make it happen without added expense and some finagling with the City regarding ADA codes. I am a huge concrete fan. I couldn't do the concrete but found tile that looks somewhat like steel or a polished concrete, and I also did the floating counter in bamboo.We are still working on this bathroom and just yesterday put the tub in so we could see what it would look like (not installed). Good luck and post some pics when your project gets started--can't wait to see it!

Which drain do you plan on using? I have just installed a Quick Drain USA channel drain with large black 1'x2' slate and 1'x2' Marble looking porcelain tile.

I had to make a couple slight adjustments to this beautiful drain to insure that the money view has the drain right tight to the main and side walls.

Quick Drain USA comes with a Nobel Sealant water proofing membrane attached to it out of the box. This drain connects to our standard 2" plumbing lines with a Fernco type fitting. I have personally flow tested this drain (28") to 22.3 Gallons per minute. This flow rate is very high and ideal for multiple head showers. Check your local codes. Some times you may need to build a Water Sculpture and not a Bathroom!

ACO has a nice drain for a mud bed install but getting the drain tight to the wall will require slight framing and structural adjustments. Not many. My friend wants this drain with the Red lights for her new en-suite! I'm sure that this drain as well could be modified and set into a standard Kerdi drain assembly (voiding all warranties and may or may not work) - I have not received my ACO drain as yet and will advice more on this shortly. I have been chatting with Mr. Guse, Western Canada Area Sales Manager ACO Systems Ltd. for the past 12 months and he informs me of late that there will be more options for water proofing tie ins for their ACO drain. Some online information shows the waterproofing membrane flat and this is not what they want to my knowledge - I'm told the new PDF file is being worked on by their technical department. Mr. Guse suggested I contact our QuARTz by ACO Technical Services Specialist in Casa Grande, Arizona. His name is Ben Newcombe and can be called at 1-888-490-9552 or at bnewcombe@aco-online.com.

I had a training meeting with Doc Warner at Cantu bathrooms here in Vancouver a couple weeks back and the CeraLine drain is top shelf. So many custom trims available and fine tuning the drain assembly has been so thought out. I have two on pending order and can upload a few pictures in a couple weeks. Contact California Faucets to find a display drain near you. This drain has just been launched and not all showrooms nation wide are stocked. I will have 2 here in Vancouver for display if you need more pictures or would like to see them up close.

There are tons of examples of channel drains online. Search "Channel Drain pictures" When the drain is tight to the wall - this look can't be topped. If this is not possible consider it under the shower entry door. Consider as well a second floor drain near the entry to the bathroom and closer to the vanity. This drain can be a back up and is par for the course in Australia and many European cities.

Since concrete is porous, how do you plan to waterproof your shower/wetroom? I don't see how plain concrete without a preslope of some kind would work for a shower, much less be able to be done for the whole room in a curbless situation. Tile, sure. As long as the shower portion itself is recessed enough to accomplish the slope needed, you can Kerdi the whole room and preslope the shower just fine. Unless you are going to build the shower preslope, Kerdi the whole room, and then pour concrete? What type of concrete would you use in that situation? Fiber reinforced would be necessary if the thickness was less than 4", and even fiber reinforced and admix modified thin slabs of the size of a bathroom would need control joints to avoid cracking upon cure? THe biggest downside to fiber reinforced that I can see is that you have the "fuzzies" to deal with and you may not be able to trowel it as smooth as you envision.

I'm getting ready to do a barrier free shower/toilet area at some point in the future due to my husbands health issues and I'd be really interested to see how you solve problems associated with using concrete. I LOVE stained concrete and have it in my sunroom currently, but it's not a wetroom.

Quick drain should arrive this week, then I will begin framing and slicing joists to accommodate the slope as I want a curbless shower. Right now leaning towards a granite slab with a leathered finish as a floor. Getting a bit of static from the building department about how it is unconventional construction, yada yada yada, though I convinced the building inspector that I know what I doing and have solved the relevant issues. Will probably waterproof entire floor as getting the the 2" drop from curb height, the finished floor, will necessitate too much of a slope on the shower floor, legal but uncomfortable, will go for the minimum of 1/4" per foot. To waterproof will use the Noble TS which comes preattached to the Quick Drain and thin set that to a beefed up plywood floor then set floor directly to the TS. Uncharted territory and hope I don't end up like a pioneer with arrows in my back.

If you can make concrete bathtubs, sinks etc, there is no reason why you can't do a concrete shower floor. Check out this guy's website: http://www.concretecraftsmen.com/portfolio_home.swf
As long as a high density mix is used, and some waterproofing modifiers in the mix. Look up polished concrete floors also. Those floors don't even need sealing since they are so dense.
Grout is also just concrete. You can also get pre-cast concrete shower pans. I remember seeing on in a hotel once. The shower floor I did some years back, I used a liquid membrane first, to the subdrain. then poured a high density concrete over it.
I'm not a professional, just a concrete hobbyist. Frankly, there are a lot of nay-saying pros out there who are just stuck in their ways.
Concrete is fantastic in a shower IMO. No grout lines. Slab-like clean lines.

I can help Zinnah.

I can offer you some detail drawings on the Quick Drain install. I have a complete set of specs here on my Mac.

I just received these 2 weeks back from Quick Drain USA head office.

What is your set up.

Can you email me cross sections and elevations. I have promised to help Joseph out with these installs where ever they are.

How can I help?

Can you please post details & photos as you progress through this Zinnah? My husband has MS and is in a powered wheelchair. We remodeled our shoe-box single bathroom 6 yrs ago into a great all-tile barrier free shower but concrete has intrigued us since we saw a home completely floored in stained concrete. We're moving into a new house that we might possibly buy and will need to make renovations. Regardless of what house we ultimately buy, we'll have to do a barrier-free shower & would love any ideas. Thanks!

Josef at Quick Drain USA has offered to share with me the plans for a custom shower they did a short while ago.

This shower was designed at concept stage so the forming boys and concrete crew had cross sections and elevations for there layout.

The forms needed to make this happen are simple. Josef and I are working on some finer detailed drawings. We can send them to you if you like and I will have them online within my pages as well at my No Curb Blog Site.

Josef is waiting for a TV show to air - and has agreed not to post any pictures until after the episode appears on TV. Once I get a copy of this show and receive my new info I'll let you know where you can find it.

Your shower concept sounds killer. I ask this question for you to ponder.

"If you have a failure of some kind and water gets between the waterproofing membrane and the concrete can the concrete breathe? Or is it in of it's self a moisture proof substance?

firsthouse that bathroom is great! Love all the elements you've chosen... bathtub, vanity, big tiles, backsplash...
