You're really making a big deal out of nothing. As long as you owe them money, the drain will be placed perfectly and pass inspection. Relax.

Treb- that response to the OP comes off to me as a bit patronizing, but maybe that's only me. You would fix it right, mongo, Bill, and a whole bunch of other guys who know what they're doing and take pride in doing things right would fix it, but there's many stories posted here of people who are hired who don't have that ethic.

AHMIowa- I don't know squat about linear drains and what needs to be done. At the least, for your peace of mind, can the inspection be rescheduled til after its redone to help give you peace of mind?

Plumbers and builders most times do not know the complete concept for a barrier free shower. Your team should have a plan from drain, to waterproofing to grading. Thin-set and grout should be selected as well. If you do not have a plan on paper they can show you.

Then they are winging it and you will get most likely a shower that close to being perfect.

What is your X axis and Y?

Are you using a capillary break?

Have you soaked tested the tile choice?

What is the grade change outside the shower?

How much water can the shower hold in inches before flooding the home?

These are the basics. If you do not know these answers you need to find them out now. Sooner than later.

"a) Is this an easy thing to fix?"

I thought I answered this question well, but I'm always interested in how my answers are perceived. Thanks.

I am hoping you did your homework and Hired a contractor with the proper skillset to build Linear drain curbless showers.

The industry currently is telling everyone " Buy our drain and/or kit" Its so easy...

It is NOT!

It does require a different skillset to properly assess a joist structure, and lower the shower area "properly" as well as building up the substrate and subfloor. Often times these installs require A Thinbed and topical waterproofing approach which many tile contractors still dont have an understanding of.

You should be looking for A contractor with exactly this proven skillset.

Did you do that first or are you doing that Now??

Be sure to request your shower pan is Flood tested prior to allowing them to tile your shower.

Wow.

Trust is earned. I think once you ask better questions and get some good answers you will gain more trust in your crew.

SECTION P2709 SHOWER RECEPTORS

P2709.1 Construction.
Where a shower receptor has a finished curb threshold, it shall be not less than 1 inch (25 mm) below the sides and back of the receptor. The curb shall be not less than 2 inches (51 mm) and not more than 9 inches (229 mm) deep when measured from the top of the curb to the top of the drain. The finished floor shall slope uniformly toward the drain not less than 1/4 unit vertical in 12 units horizontal (2-percent slope) nor more than 1/2 unit vertical per 12 units horizontal (4-percent slope) and floor drains shall be flanged to provide a water-tight joint in the floor.

P2709.2 Lining required.
The adjoining walls and floor framing enclosing on-site built-up shower receptors shall be lined with one of the following materials:

1. Sheet lead;

The important thing here is knowing the difference between the Americans With Disabilities Act (ADA) and local code. Code is for safety and the ADA is for civil rights. The code tells you what size and type of sign you may put in your business, civil rights keeps you from putting "Whites Only" on your sign.

A local division of inspection would very likely find themselves on the wrong end of a federal lawsuit if they did not issue a wavier to the code on a remodeling project involving ADA compliance.

Things get vague here - our goal is "aging in place", supporting my mother to visit or possibly stay longer, and facilitate my already needed knee-replacement that I'm putting off as long as possible. Talking to our local building inspector, I confirmed that the 2" curb/drain requirement can be bypassed - but not the 1/4" per foot slope. So we'll see how it all goes.

Hi All, Let's remember to stay on topic and be polite to each other, even when our opinions differ on the best ways to approach design. Thanks!

OK Emily.

I have edited the other reported posts of mine you sent me.

Thanks all...things may be looking up. The GC organization has assigned a more senior project manager, who has (all but) agreed that things weren't right. We may get there after all. Crossing fingers! I appreciate the constructive thoughts...
