Plumber Job - New Germany, KZN, 3610

I need quote for a shower installing in a wooded cabin use as a granny flat. There is already a bathroom installed ( Toilet & Sink) however the entire place is wood and not waterproofed and the is a heated shower head attachment already there but the shower never got finished, there is a shower base and doors which where purchased but not installed. Probably worth a call in to have a look. I don't know if waterproofing, tiling and installing the shower that has already been purchased will be possible or if I need to look the prefabricated shower option.
