Hi everyone. In my extension im having a wet room with a shower thats flush to the floor with the same tiles as the rest of the room divided by a glass screen. The floor in the shower will be shutterd with the fall towards the trap like the preformed trays. Will I need to seal / tank the conceret before tiling over or will it be fine?

you will definitely need to tank the area. Tile grout will eventually let water through and concrete is porous.
Tank the whole area.

My personal favorite is to use this on the floor: http://www.impeyshowers.com/luxury-wetrooms/waterproofing/impey-waterguard-tanking-kits.aspx
and this on the walls: http://www.bal-adhesives.com/products/waterproofing-kit/

You only have to do the areas which will see the most water. If you're using a shower screen, you dont have to tank outside that.

I've only ever tanked plasterboard and chipboard before, so you might have to seal the concrete. Read the user guides.
