I'm planning to build a sunken bath/wet room type shower. The plan is to raise the floor of the bathroom by 18" and then build a bath with its bottom just above the original floor level (to allow for drainage). What is the best way to build, waterproof and tile this custom tub. It will be box shaped with no curves. Basically like a sunken wetroom shower.

I once built a bath floor with white cement, and then covered it with sikatop-107 seal. it was an outdoor shower but it will fit also for an indoor one. here is a link to an article i wrote about it in my website. sorry, it's in Hebrew - but you still can look at the photos :)
you can build a structure out of salvage materials, plaster a thick layer of cement on it, and finish it with the sikatop-107 seal.
