8ball Posted May 8, 2019 Share Posted May 8, 2019 Hi all, I am attempting to refit my own bathroom after the bathroom fitter let me down ?, at present I have a rotten and very thin chipboard floor fitted to the floor joists with a thin laminate layer and want to tear it up and replace with a decent floor. I wanted to put down a new 22mm chipboard/ply and then a 10mm tile on top but this makes the floor level much higher than the original and the transition into the bathroom from the hall will surely be a trip hazard? does anyone have any advice on what is usually done to adapt to a thicker floor? the hallway has carpet. Thanks guys? Link to comment Share on other sites More sharing options...
PeterW Posted May 8, 2019 Share Posted May 8, 2019 Joists 150mm...?? Can you fit battens / 3x2 inside each joist at 22mm below the top, then cut and fit 22mm chipboard between the joists..? Then overlay this with 18mm ply, glued and screwed at close centres (200mm) and then tile on that...? 10mm tile seems pretty thick when you then add 2-3mm for adhesive..? 1 Link to comment Share on other sites More sharing options...

Oh yes that's a good idea, I was also thinking about taking 5-7mm of the top of the joists with a planer as its a small bathroom and would not be a bad job. Your idea would really drop it back down and maybe the option I will go for ? Thanks PeterW Link to comment Share on other sites More sharing options...

The "Just don't" ? OK Peter I'll make sure the planer stays out of the bathroom and again thanks for the top idea ? . I'll be using a stone resin tray for the shower will this be OK to lay directly onto the joists with adhesive of course making sure its level?

PeterW Posted May 8, 2019 Share Posted May 8, 2019 Still wants something under it - can you just put 6mm ply under the tray and that will make sure nothing moves. 1 Link to comment Share on other sites More sharing options...

Juj Posted May 8, 2019 Share Posted May 8, 2019 (edited) How about hardie backer board? Assuming you're tiling of course. Edited May 8, 2019 by Juj 1 Link to comment Share on other sites More sharing options...
