A costly affair, unfortunately

and a very inconvenient one.
We just had our bathroom done. I don't have the exact figures with me right now, but I do remember roughly.
We had to buy tiles for about 50 m^2 for two bathrooms because you need to include walls and floor. They're about the same width as you provided.
The tiles were R150/m^2, although that was after hunting around because we saw the exact same tile at few other stores for R280/m^2. So that came to about R8 000 (including mosaic for the shower).
Tiling cement and grout was ~R500, cornices another R500.
We replaced the existing accessories with new ones (toilets, tub, shower, sink, fittings etc.) - that came to about R7 000. This depends on what you choose, really, and can either be much more or much less.
We used a well known tiler who's done work for various people in my gf's community, so we were able to see the quality of his work. He charged R15/m^2 to remove the existing tiles, R35/m^2 to lay the new tiles and R500 to build a new wall for the bath tub - so about R3 000 in total for him.
We also had to have the plumbing redone - that came to about R3 000.
So in total it was about R22 000, and that's after shopping around and finding a good tiler and plumber who don't charge a fortune. Key is to look around, don't be impulsive otherwise you will pay for it.
I can have a few pics up a bit later if you're interested.
