My bathroom is situated upstairs in a converted roof space and has a dormer window.It also has an airing cupboard where combo boiler is now housed and I was wondering whether it was feasible for a wet room conversion.Presumably ant floor level there must be some kind of tray which is no more than the thickness of the existing floorboards with a fall to the shower waste
converting to wet room feasible?

Yes it is feasible. The wetroom formers are 25mm thick so you would need to overlay the remaining flooring with 6mm ply and then use a tanking kit to waterproof the entire floor and walls.

but that former would surely be thicker than a standard floor board wouldn't it? I am assuming it would be sited where the existing shower is , but with the tanking ,a good 6-8mm above the level of the current floorboards.that surely must mean thaw where the tanking meets the door the level would be higher still, or am I missing something?
No other way as far as I know! Someone else may know better.
Most people are okay with a slight difference in height at the threshold.

yes but as long as its not too high so that i cam open the door
Trim the bottom of the door

yes! Having watched this video its .quite clear the resulting floor will end up higher than what it is now so one would need some kind of threshold joining the edge of the tiling to the carpet in the hallway

you could replace the floorboards with ones that are the same depth, you can get 22mm formers and 22mm boards having a quick google.
also that video makes it look a lot harder than others ive seen.
the latex tanking stuff looks much easier to use than their flexible grout stuff.
not sure which will be better?
also what that video doesnt say which other do is, you need to make sure the boards around the shower former tray dont move either. they have supported the former with ply which is better than other methods ive seen, but you would probably want to support the surrounding floor in a similar way, because if you step off the shower tray on the the normal floor and that floor bends you could break a water proof seal between the two surfaces
I figured when i do mine im going to replace the whole floor in the room (its pretty small) with new board the same thickness as the tray

You may wish to use altro flooring.
as a safer alternative to tiling? Yes I think so , although I would have to get it past aesthetics head honcho, 'er indoors
