Lowering bathroom floor

Postby shudgetamanin » Wed Jan 23, 2008 2:45 pm


Just bought my first house and so am totally new to DIY.

I have a bathroom that it is 6ft 2 x 6ft 1 and the ceiling is only 6ft 8.
I therefore want to lower the floor by 2 inches to give me enough room to fit an overhead rain-like shower rose thing - at the missus' request.
I've taken the floorboards up and found that the joists are 6x2.
To get an extra 2 inches I was thinking that I could replace the 6x2's with 4x2's and so wouldn't have to mess about with new hangers, repiping etc...
As the room dimensions are slightly over 6ft, are 4x2's acceptable; bearing in mind I also want to tile the floor as well?

Any help, positive or negative, greatly appreciated.

Thanks in advance.

Simply Build It

Don't do it, you'll be sat down stairs if you put 4*2 in. Can you not raise the ceiling height instead as this is much easier?

Gentle reminder that you have a legal duty of care to those living in your house as well as those visiting it. You are also legally obliged to leave it in a safe condition if you ever sell it. Putting 4 x 2 inch timbers in the floor will be very dangerous. Please see the projects section where you will find projects on building regulations and floor joists.

Thanks both for your replies.
I did look at the dimensions on this site in the projects area and realised that I was touching on the bare minimum, but wasn't sure about the Newtons per square metre and suchlike :?
Unfortunately I can't raise the ceiling as the bathroom is under the turn in the stairs.
On that note, my only available option then is to reposition the hangers - I'll get builder in!

Thanks again.
