Plywood sub-floor in bathroom

[steve.c]

Could any one help me with a problem I may encounter in the future. I recently fitted a new bathroom suite but as my floorboards weren't level I laid a 6mm plywood sub-floor under the suite. It has only now occurred to me that were I to have a leak the ply could not be lifted without removing the basin or toilet. Is there any way of cutting the plywood while it is laid, for instance would something like a dremel work or a small angle grinder. Any help would be appreciated

It’s normal to do it that way & modern T&G chipboard floors will give the same problem, I wouldn’t worry about it. As a precaution, I make as few pipe joints under the floor as possible & then only solder or solvent weld & fully test; & if its 2 story, you can always go up through the ceiling below. It’s difficult to plan for every eventuality so be positive.

Your not planning to tile that floor are you

Thanks Richard. Reassuring to know I did it the right way. Will keep my fingers crossed no future leaks.

I would imagine if you ever need to cut the ply, you can use this tool
