Waterproofing i not so sure i need to check with my contractor.
But so far the tiles wise is super expensive without include the tiles.
My bathrooms stays around RM4K with white horse tiles laying + water proofing (not sure how many layers i need to check) and an aluminium door.
my sq bout 6 x 8 sq too
Try get few quotation and compare don't simply fall into their trap.
And make sure finish the work only make the payment.
Installation for water tap, water heater, toilet bowl, tower bar and sampah sarap
can be costly too, so if possible make sure they can do it for u too.
One important question.
did u reposition ur toilet bowl, water tap etc? it could be cost up to RM700-1000 if u do it for ur bathroom.
the installation of the sanitary and water tap all that is already included for the plumber cost. I separate it
I didnt change the location of the toilet bowl all that, I jz hack off whole bathroom tiles and change new tiles.
