Its,a good sized job, have to remove tub, walls and redo plumbing. Look at you tube for tutorials on how to remove tub and make a shower. Good luck.
Here's a step-by-step video: https://www.youtube.com/watch?v=RoB3ziqk0oI
If your tub is built in, you will need to first turn off the plumbing and then demolish the wall holding the tub in place. To do that will require you pull out the plumbing from the wall (f there, an it usually is). Then, you will need to remove the tub. Then, walk in shower will be required, and there are a variety of ways to do that. I suggest you get a professional builder to do most of it unless you have the skill. There are videos on line for how to do it, but, generally, it is an advanced DIY project.
thank you , i'm hoping H.Dep sends me home with all the necessary new plumbing or a kit for the style n size i buy. then follow the dots.
no skills just the need to get something done without putting someone else's kids thru college.
