just to say your drawing is pretty good:) actually perfect for somebody like me:) if the tile and pattern are important-i'd try to save on the vanity by looking into second hand. sometimes folks sell very decent or even new stuff because they remodel for example. otherwise i think the prices you posted are very reasonable pattern is more laborious and will probably require more cuts=ordering more tile i know new vanities cost a lot..anything new wood does. so i'd shop around for that maybe, but splurge on the tile that's important to you. tiles are harder to get second hand:) lol but you can score a very nice vanity, without paying full price in Costco. of course one needs to get lucky. so decide whether you have patience for hunting like that. i got two of three vanities i needed on Craigslist..one is pretty straightforward just a big improvement from the old one, and cost me around 250 or so with nice clean countertop(looks like quartz), integrated sink and faucet. it's not 60 inch that's true..it's 37 inches. it was brand new too. another one was around the same in terms of money, it's smaller, but it's handmade and unique and i'd never be able to get something like this in the chain store. so i'm happy i took my time hunting. but i realize this Craigslist thing is not everybody's preference, for various reasons.

If the tiles are loose then the shower was not built properly. Cracks in the floor and loose tiles mean that you have water getting behind them. If the person who built your shower did not know how to make the tiles stay up or to make a floor that would not crack, then there is an excellent chance that it is not waterproof, either. I say that because the waterproofing is the HARD part, and the parts that are failing in your shower are the parts that even a novice usually gets right. I would stop using this shower immediately. It has to be torn out, right to the studs, and you have to have a waterproof shower to replace it. You have the choice of another tile shower - which is a complicated system that must be done right to be waterproof. Many, many showers are done incorrectly and many get away with cutting some corners while others cut the same corners and get leaks. So you have to study how a shower is supposed to be built (this forum has info on it if you search) in order to know who to hire. Other options for a new shower include a solid surface like Kohler Choreograh, Corian, Swanstone, Transolid, HI-MACS, Staron, Avonite, Livingstone and one by Wilsonart. These have the advantage of not having grout, being mildew and mold resistant, and they will probably outlive your house. If they are ever scratched, they can be repaired right in place with sanding the surface because their color goes right through and they have no surface coating. They are more expensive, though. Then there are the other hard wall products that have a surface coating - these will last years too, but are not repairable by the homeowner because of their surface coat - Marbleite, Onxy Collection, cultured marble, cultured granite of any name. These are a bit less expensive. There are also Kohler cast iron shower pans that will last forever that you can use with any kind of wall. If you go to Lowes or HD you can see there are wall systems that are not solid surface that look pretty good that you can put above a shower pan. You have to research on how the shower pans should be installed, as people never used to install them in mortar beds (depending on the shower pan, it might be concrete mix or even thinset) and they would crack. Now we know that all the voids under the pan are supposed to be filled so this shouldn't happen. The least expensive materials to buy are probably acrylic shower pans and walls. Delta sells one at Home Depot that would be under $600 for the pan and wall. Would it last very long? Maybe not. It could look worn or stained in a few years, and since it is adhered directly onto studs, there is a chance that something could puncture or crash through the sides. As with any shower, the cost of installation will far outweigh the cost of the materials. If you have to pay to have someone to install it, it is always best to get the best materials that you can afford. I have given you some ideas, the home improvement warehouse stores are out there with their products, too. Get shopping, and come back if you have questions. BTW, many tile pros recommend that natural stone - especially marble - should not be used in showers. As one of the pros on here likes to say, "marble is just a hard sponge."

Since you're having issues with the shower I'd focus on that. Clear glass doors would go a long way toward updating the space, so would a lighter paint. I don't think the tile around the tub is bad at all. The mirrors are fine. You could even frame the top with some natural wood. Pick some bigger tiles for the floor if you want. But really, I think the shower and paint would make a big difference!

We renovated recently and removed an old cast iron tub that had been reglazed badly several times - it was tough for our plumbing team to find someone to cut it up and get it down the narrow stairs.. we opted for an acrylic model for our replacement, I absolutely love old things too but definitely appreciate the new pipes that our team was able to run to the new bath as well as a nice level subfloor 😅
