I am too scared to touch any of the "beams" that are currently in the bathroom. I call them beams, because they appear to be doing more to hold up the ceiling downstairs than support the floor upstairs. All of them move alarmingly, and at least one of them in all 4 directions; up and down, front and back, side to side, AND it rotates. How to put in a bathroom floor without disturbing these has been playing on my mind since July, but now I have a plan.
At least, I think I have a plan.
The only way I can see of making the floor solid and stable will be to create a new floor bolted to the wall above what is already in place. What I will do is make a bearer (I think that is what it's called) out of 50mm x 150mm treated pine and bolt it to the external wall using 90mm long anchor bolts (goujons d'ancrage, apparently). This measurement may change, because I am not sure what that 90mm distance is - the wall is only one brick thick. The trick will be in making this piece absolutely level as it is quite likely I will be doing this on my own.
I will then attach another bearer to the bearer holding up the landing. This SHOULD be fairly simple (I hope I haven't just tempted fate there). Once that is done, I will put the lap jointed joists in place (spaced at 500mm centres), bolting the outside joists to the side walls. All this will be double measured and constantly checked with a spirit level. Everything is going to be screwed because I still can't hammer a nail in properly.
At this stage I will do the plumbing (or pay to have someone do the plumbing). Most of the pipework I should be able to do myself, but we will need a new connection to the egout (sewer) for a toilet and this will require a proper plumber.
Once they are plumbed a double layer of 9mm floor panels will be screwed to the joists, and we will almost have a new bathroom.
Albeit one missing a wall and without a door. We have chosen a door though, and typically, it isn't the cheapest door in the book. It's a nice sexy door with porthole! I would provide a link, but the Lapeyre website is now flash based (and therefore doesn't work properly), and I will not encourage that sort of behaviour.
You may wonder why I am writing this up before I do it, and there are two reasons. One is so that I have these little French hardware words written down somewhere, and the other is so that people who know about this building and carpentry stuff can critique my plans (please?) before I start. What I know about carpentry could be carved on the back of a postage stamp with a 4 inch chisel.
