While I'm STILL waiting for our roof to be finished, I've been busy thinking how I can make our build more complicated and expensive, and have started to think about the plant room and whether it might be an idea to have a drain in the middle of the floor. The room won't just be for the plant but it's also a boot room etc, so it might be useful to have a drain and would also be useful if any pipes in there sprung a leak. There is already a 110mm stack coming up through the floor that I could T in to, and the screed is yet to go down, so have about 100mm height to play with. Should I forget the idea? Are there proprietry "floor drains" for this sort of thing, or could I just use a wet-room shower trap?

Thanks all

Following with interest, as I could do this in our garage! 

standard gulley pot would be ideal as they have an integral trap to catch any rogue items that may accidentally fall in, also stops the smell. screwfix/toolstation do them.

Thanks Dave, looking at those I think they are going to be a bit big, only got 100mm depth to play with and a distance of a few meters to the stack. Would a shower trap not do the same job?

I'm going for a square shower trap. It's only really for an emergency in event of a big spillage or leak. If you want to go get the floor wet regularly, then you'll have to go down the whole wetroom tanking and sealing route.

Our plant room was next to the wetroom so the floor was tiled without any upstands anywhere so if there was a leak it would find it's way into the wetroom shower drain.

It's a top idea, every room in a house with pipes should have one I think. 

 

Consider an airless trap as a wet one will dry out quickly with no regular filling.
