I have a tiled shower that leaks that I want to tear out and replace with a shower that requires no maintenance (grout sealing) and never leaks. Is a prefab shower the only option? Most prefab shower I have seen is pure white, which is not very attractive. Is there an option that combines color like tiled shower, and leak free/ maintenance free like the prefab shower? Obviously even a prefab shower require regular cleaning so that is not considered "maintenance" in this context.

First of all, let me just admit up front that I am a complete idiot. A friend of mine (my partner's boss's wife) has a glamorous art studio in downtown Atlanta. The kitchen, however, is not so glamorous. She hired 5 guys to update her Kitchen with Ikea cabinets and the design they came up with was terrible. The guys had never installed anything Ikea before, so 4 months later, they still had only barely managed to get the cabinets installed (identical to the previous layout). When I saw the mess they had made, she had just fired them, but paid them a total of around 5kl. She'd also had to hire a plumber for $200, an electrician for %1200 and she was really upset. I offered to help and because I am an idiot, didn't set up a price in advance. I redid the entire kitchen, installing the cabinets the correct way, moving the range, built custom cabinets, tore out a set of built in shelves, built a custom enclosure for the refrigerator, re-plumbed and wired the bathroom, installed drop ceiling and pocket door in the bathroom, modified some built-in shelves for the entrance to the bathroom, installed cabinet lighting above, below, and inside cabinets. I painted, hanged drywall, established a water supply shutoff for the floor, rerouted the hot water so they didn't have to get hot water from the basement (4 floors below), I scraped, cleaned, and caulked the windows. The list goes on and on. And that doesn't even mention the custom bar I installed. I also managed the returns of the excess cabinets where she got about 1.5k back. And I did all of this by myself. This is a classic story of why you get agreements in writing in advance. But since I didn't do that, I need some advice. Now, the project is done and she absolutely loves it. But I have no idea what to charge for this or how to organize the charges to make sense. Any advice would be greatly appreciated. Also, how do I estimate the charges? Where do I find what's reasonable in this case? Thanx in advance for your kind consideration.
