Bathroom Floor - Tile Advice

[Matty]

Hi Guys,

Wanted to run past the intended process for a bathroom floor project..

First floor bathroom, 1930s house, will be UFH with Porcelain tile. Floor boards need to be ripped up to sort out the plumbing.

Replace with 18mm PLY, glue, screw and prime
6mm Insulation board, with adhesive
Prime Insulation board?
Loose wire Electric UFH
Adhesive and tile

Any better steps to take or parts to improve/add upon?

Cheers!

One I’m doing at the moment.

Old chipboard removed
Pipework altered
New 18mm moisture resistant t&g chipboard
6mm Hardie Backer, glued screwed, taped.
Warmup
Self levelling
Tiles

If you would prefer to use insulation board I would probably use 10mm as opposed to 6mm.

This ready for tiles today.

Perfect thanks, that sounds like a much better option with the chipboard. Is it as rigid as ply? I'll be going onto the floor joists.

Are you using loose wire UFH? I take it the self levelling is both to protect the warmup while tiling and give a nice flat surface to work with?

Thanks for the info, pic looks great very tidy

If you decide to stick with the ply make sure any joints are supported as it isn't tounge and groove

Ok, thank you, it's a fairly small area so will make sure joints sit over the joists

Consider the joints running at 90 degrees to the joists , maybe you won't have any
