Drainage on a wetroom

Hi there, apologies I'm very new to DIY! We have recently installed an Aquadec wetroom which looks great aside from the fact we can't use it without the water going everywhere.

We have a glass screen but where it ends the water seeps everwhere flooding the remainder of the bathroom.

We have adequate drainage but the slope in the wet room won't pass all the water to it.

So that we don't have to take up all the floor tiles to build the slope up can anyone recommend anything we can use?

We were thinking of a shower threshold to sit where the glass finished to help direct the water but can't find any anywhere.

Anyone else had this problem?

Thanks

Becky

Had exact same problem a while ago.The shower screens have a gap of about 1 inch at the bottom and due to a very bad floor the water went everywhere from the bottom of the screen.
i got a chrome strip from B&Q and siliconed it to the bottom of the screen. A bit fiddly but it did the trick. good luck

Suggest getting the installers back to fix the floor (unless you did it yourself?) Why create a 'wet room' if only to seal off the shower area?
