Extension Build, new wet room

[duchard]

Building is starting on my 1st floor extension very soon and as part of the extension I am having a wetroom added to my new ground floor bathroom (old kitchen). Since the wet room area will be a new build, new walls, floor, etc, I am assuming that the wet room floor can be concreted to allow for drainage slope (1:100) at build time. Giving me a nice flush drained floor? My builder assures me he will have all the drainage sorted so I'm assuming no shower tray is needed and I can just tile over the concrete floor with the gradient?

Does this sound right or am I missing something?

They should form the slope with the screed, to get the gully nice and flush with the tiles.

You do need to decide on the tiles before hand, although some gully's are adjustable.

Thanks for the response do it all.

So for the screed to have a slope would a mould of some sort be needed?

Why would I need to select my tiles before this process?

It doesn't need much of a slope, normally done by eye.

The tile thickness will change the heights, so could be be anything from 10 -50mm
