There were floorboards missing from under my bath and a few of the other floorboards had been hacked by the previous owner, so I want to get new floorboards. I'm undecided whether to just get new ones to replace the missing and damaged ones or whether, as it is such a small room, to do the lot.
I know chipboard was recommended to me in another post but I don't like the idea of that in a bathroom.
In my old house, the floorboards were 16mm thick. I went to a local timber merchant and they planed wood down to that size for me. It did not have tongues and grooves, but I never had any problems.
This new house has floorboards 22mm thick. I am finding it hard to find anything that thick. Places like Wickes sell 18mm thick floorboards and some builders merchants I have contacted sell 20mm ones.
Jewsons were advertising a 22mm but when I got there it was a nominal measurement; I presume that means before it was planed? They were actually 18mm thick. They do a 25mm nominal one that is really 20mm thick.
I am thinking I could do the whole room in 20mm thick boards and the 2mm drop from the 22mm boards on the landing would not be noticeable. I am unsure whether I could "patch" the room with 20mm boards alongside the 22m ones without it being noticeable. 2mm doesn't sound a lot and it might be hidden by whatever I cover the floor with (currently undecided) but I am not sure. Particularly in a room where you will be barefoot.
I suppose I could try and find a timber merchant and get them to plane something to 22mm and not worry about the tongues and grooves. Is that a better idea? I know the tongues and grooves are supposed to strengthen the floor and prevent draughts but are they that important? What would the group recommend?
