Browse Forums Bathrooms and Laundry 1 Oct 06, 2008 11:10 am Okay, our first big reno job is to redo the bathroom. We plan on starting next month and we have just found out that there are no floorboards under the current bath and it is just sitting on the floor joists (i think that the term). We have also found out after taking some tiles out that the remaining floorboards are water damaged and rotted. Now my question to you guys is..... what would be the best thing to replace the floor with that's not going to cost me a lot of money.
Any advice would be welcomed. If at first you don't succeed, try, try again. Then quit. There's no use being a damn fool about it. W.C. Fields Brought Established. Re: Replacing bathroom floor 2Oct 06, 2008 3:54 pm Wingies, when we had our bathroom renovated about 9 years ago, in an old house with wooden floorboards, the entire bathroom floor was ripped out and replaced with a concrete slab.
I don't think there is any other way around this. Re: Replacing bathroom floor 3Oct 07, 2008 12:52 pm Thanks helyn,
I think thats a bit drastic, I am sure that I can place something down that will be sufficient. We plan on tiling the floor so I am sure that there is something that can be placed down to replace the floor boards. Might need to ask a builder If at first you don't succeed, try, try again. Then quit. There's no use being a damn fool about it. W.C. Fields Brought Established. Re: Replacing bathroom floor 5Oct 07, 2008 1:52 pm Will the chip board be strong enough to support the weight of a full bath along with the weight of people in it If at first you don't succeed, try, try again.

You'll need to put cement sheeting and waterproofing as to lay tiles (or using cement which is the old school way). It's the bearers and joists that provide structural thingy ma bib, Sorry I can't explain myself well here and my partner would explain it better. Re: Replacing bathroom floor 7Oct 07, 2008 6:34 pm Chipboard/ fibro underlay is the cheap option and can be problematic down the track if there's a leak.
The best way to do it is to use compressed fibre cement sheets. You will need 15mm thick for 450mm joist centres or 18mm thick for 600mm joist centres. You then just lay a sand/cement screed over this (after water-proofing) for you run-off and tile. I agree a suspended slab is a complete waste. Re: Replacing bathroom floor 8Oct 10, 2008 6:37 pm I believe they call the fibro material 'thicksheet' It's about 1/2'' thick and is screwed to the floor joints. Pre-drill your holes for your screws and with a bigger masonry afterwards, drill a couple of mm deep into the thicksheet so that the screw are recessed. Obviously use galvanised or even treated pine screws! The screw hole and joints are then filled/sealed with a special sealant that specifically recommended for this purpose. Afther that, it's time for screeding, waterproofing and tiling...
I have used this system for my place and for my clients. Don't go down the concrete route...you have perfectly good joists! Use them! Re: Replacing bathroom floor 9Oct 11, 2008 6:35 pm i gutted my reno house today. The pre existing floor was that rotten there wasnt a floor left, and the vendor/s still showered in it. a leaking hot water pipe destroyed the whole back half of the house.
we are re stumping and new sub floor for entire house but the bathroom section will be standard 100mm x 100mm h/w bearers at 1.2 cntrs with conc. stumps and 90 x 45 t/p for joists at 400 cntrs. plated at walls for bottom wall plate to sit on. the shower cavity which is 3 mtrs long x 1.6 mtr wide will have the subfloor recessed down from top of main sub floor this will have compressed fibre board which has a flexible membrane painted on it in a lattice formation. then a 80mm thick reinforced concrete slab poured over the top, this is also has membrane on it as well as all fiber board on walls to create a seem less membrane in entire shower cavity. we are doing it this way as we want the bathroom tiles to flow into the shower without any lipping. the bathroom floor will be yellow tongue with membrane. then compressed fiber cement sheet and membrane . the tiles will be adhered with mpp adhesive direct to membrane the mpp comes with a adhesion guarantee if you use there membrane as well the tiles are 600mm x 600mm with acrylic impregnated grout. in our case the suspended slab is the only way to achieve the end result we wanted.

Re: Replacing bathroom floor 11Oct 13, 2008 12:45 pm Screeding is where they put a thin layer of cement on the floor to level (smooth) it out. They did this when we took up the carpet and put vinyl down. the concrete under the carpet was uneven so they screeded it.

KWOOD2 Dukekamaya Davinci I_BUILD If you have any problems you should consult a builder. Once the floor is done….properly, then you can take care of most of the reno on your own.

I think this will be fun Michelle ...... at least up until i actually start.... . Anyway my brother has just informed me that he has gotten his hands on some floor boards so I will check them out and go from there. Keep you posted. If at first you don't succeed, try, try again.

That is a good option but its a lot more hard work which is rather unnecessary. There is nothing wrong with using yellow or red tongue chipboard or plywood flooring in bathrooms. Once its layed coat the floor and walls that will be tiled in a waterproofing membrane. This is called tanking and is extremely effective and wont let any water through. Even if you were to use the compressed sheets it would still need to have a similar product to seal all joints, screw heads and where the wall meets the floor to stop any water from getting to the floor joists. I would only do it that way and have done it many times including bathrooms with floor-level showers upstairs and have never had one leak. I have an investment property and tenants moved out recently.
