Waterproof MDF used for boxing in wall hung toilet/sink

[johnpark90]

Hi,
Halfway through refurbing a bathroom. We went for wall hung sink and toilet and the plummer built a little false unit to house the cistern. Plan was to slot a bit of stone on top of the boxing and then just paint the boxing round the toilet and sink with maybe a little tiled skirting board

The boxing was built with the green waterproof/resistent MDF for the front and side panelling.

Now that it is in I wondered if it should be tiled or have some additional waterproofing. Had a bit of a google and can't see many places where MDF is either a good bathroom material or a good base for tiles.

You'll have figured out that I'm a novice at this point - had not idea when it went in that MDF might have limitations.

What do people think - Is waterproof MDF + bathroom paint enough for this location (I've got a 2.5yr old who is just about to be potty trained - probably be p!ssing all over the wall!). If not, is it possible to tile onto the MDF or will I need to get some of this rebuilt?

Thanks for any advice!

Mdf isn't the best to tile on to, you could fix 6mm ply or Aquapanel to it and then tile.

Or if you really want to paint it id use a decent primer undercoat with a gloss topcoat.

I built boxing in a set of gents toilets 4 years ago in a hotel and they are fine
