We are building at the moment and we are planning on having a free standing bath and a walk in shower so when I saw these pictures below I wondered what extra cost would be involved.
The wall itself won't cost anything because we removed a wall earlier so we would just be placing a fraction of that wall back, as far as waterproofing goes, we were planning on tiles to the ceiling anyway and his was we can maybe even save on tiling because we would only tile the shower-bath wall areas.
So as of right now I feel like this is either cheaper or we would break even either way.
But I'd love someone who has done this or similar or if you work in the industry.
Please excuse my ignorance with it all its my first time building.
