Views welcome - stripped bathroom walls prep for tiling

[Builder2011]

Thank you for looking at this post.

Bathroom being refitted. Now stripped out back to brick on two walls and lathe plaster on two walls.

What's ideal way for wall prep now for tiling and fitting?

For example :

1) Plaster and skim everywhere, then fit and tile
2) tank then plasterboard, then fit and tile
3) aqua panel? (and then whatever happens)
4) other.

Thank you for looking.

What size/type/weight of tiles are you fixing....

This will dictate what would be best route to go down mate...

And adhesive type to use also..

Dear tictic,

Thank you for your helpful reply.

The tiles are ceramic probably 148 mm x 148 mm with 5.5 mm thickness. And some border tiles 250 mm x 35 mm and thickness 8 mm. These are mainstream diy places stock. They do not do regular white tiles the same length as the border tiles, weird!

Am now considering aqua panel or glasroc H tilebacker to walls around bath which will also have a shower, this will be tiled, and then moisture resistant board elsewhere which will be painted (seems necessary to skim first).

Further consideration now is that the long side of the bath and the one short end of the bath will against walls which are both the external solid walls of the building. So the external walls are going to get cold which result in condensation / excessive condensation on the tiles.

Both aquapanel and glasroc h tilebacker have insulation qualities so would really like to dot and dab (with wall adhesive) either of these on to the inside faces of the external solid walls.

Any comments very welcome.

(Would note that this bathroom fitting is probably temporary for about a year until an extension is built.)

Thank you for looking.

Are the walls single skin or cavity??.

If single skin you will need a vapour barrier put up so the wall will need to be studded....then overboarded...Insulation boards..

Cavity walls...have a look at insulation boards...I.e Marmox insulation boards ect...there is a good few mfr out there that do these boards, these come in a wide range off thickness from 6mm -80mm+ and prices vary...

You can dot/dab the boards then use mechanical fixing thro them as well...

Your tile thickness is going to look rather odd there builder 2011,...

Maybe look into a 250mm by 200mm white bumpy tile@8mm thick...if as you say it's only for a year....you can pick these up pretty cheap..


Moisture resistant on other walls will be fine...IMO...no need to plaster skim,just tape/ joint filler and sand...then paint...
