Advice please for 'wetroom' tiles with inadequate fall for water. - Tile Advice

[Flintstone]

I have seen a handful of wet rooms where I’ve been asked to tile them with a home made fall made up of the screed and not one have been any good. All of them I had them chop up and fit a propper wetroom former!

Use mosaics on the former then tiles to come of it

I wasn't aware of what a wetroom former was at the time. In hindsight, I wish I had done my own research into what was involved.

Could people please advice how much slope would be required from the back wall to the drain, a distance of about 156 cm, as I have drawn in the diagram below, for a good drain of water?

The builders have said they will come tomorrow to try and fix the problem, but i'm not holding my breath..

Actually, having just looked into it, it seems like I did order a former but returned it because the builders had already layed the screed and said it would be ALOT of work to cut into the concrete to use it.

Its more like they could not be bothered cutting a former in

You can mess about with tile designs all you like but unless the height of the drain is decreased or the height of the floor relative to the drain is increased it is going to be the same result

The builders have said they will 'scrape' into the concrete to create the slope required for good water drainage..

They will have to lower the drain if they are going to do that!!

I agree. I am starting to realise that these builders like to minimise there work as much as possible when they have quoted a fixed rate for the job.

They are going to have to do more than scrape . As regards your earlier post go to a bathroom showroom with a spirit level and a tape measure and measure the drop .

They will always cut corners to get in and out as quickly as possible

Thanks, I will keep that in mind and insist they do that when they go about the task. Appreciate your input!

It would be easier to build it up and create a fall to the drain rather than try to create a fall in existing concrete

I see what you mean. What they say and what they'll do seem to be different things. I have minimal tiling and building experience and have my doubts about the actual practicality of what they have suggested. Having eye-balled the slope on a similar sized wetroom former

it looks like they'll have to do remove a fair amount of concrete.

If I was you I would get some one else who knows what they are doing to put right the job using the correct products and methods and take these builders to court or get your money back, they obviously aren’t capable of doing it correctly, you will be forever chasing your tale when it’s leaking a few months!
