Hi,

I have a 50's house with solid walls but very dry rendering which tends
to have hollow parts on some walls.

I have an imperial bathroom and want to put a metric bath in it!
The width of wall between the ends of the old bath were about 25cn too
short, so I am at present removing a "slice" from the old breeze blocks
from one end (rear of airing cupboard).
The old "70's" tiles are being removed together with the original tiles
underneath and of course the old rendering!!

I have allowed for 12.5mm aqua panel+glue+tiles at the shower end and
would appreciate some advice on what to do at the back and other side of
the bath (I have not replaced a bathe for some years).

I intend to make my "chiseling" a bit more even by rendering the worst
areas. Years ago I just used a cement render, has bonding/bonding
plaster replaced this or should I still render?

On the other walls I will need to have a base for tiling about 5-7mm
thick, again should I be rendering or plastering?
I assume wall boarding is not a good idea near the bath!

If bonding, do I need to also use a finishing coat, I was think of
just tiling on the bonding?

Must you put a finishing coat onto dry or wet bonding (general question)?

I am off to create more black mess in the bathroom now!

Thanks for your time
