Bathroom Floor Tanking

[Boardrider]

Please could someone let me know if I would need to tank my bathroom floor. The sub floor is pine tongue and groove. If I lay 18mm plywood on top of the sub floor and then tile with flexible adhesive. Would I need to tank the floor?

I may also install electric underfloor heating. Any advice would be greatly appreciated?

if you want to tank using NMPthen you board and seal the walls also..

Hi Thanks for all the advice, just to clarify that I do have a shower enclosure to install in the downstairs toilet shower room. I will probably tank the shower enclosure with wetdecs dura-wp product and use sealux trim between the shower tray and the wall tanking.

Is no more ply the way to go? could this be used as a base for the 1200 x 900mm shower tray?

Your going over board with this, if you really need to tank then use Dura-wp on the walls, the floor needs over boarding as your tiling it.

2 options 10mm ply or a cement board on floor............tanking the floor not worth it your base is the collection point................... Cement board is best on the floor in this case but dont be swayed by pretty pictures, they have them in your local DIY / Tile store.....................
