So my son found a frugal solution to turning my bathtub into a walk in shower. You can remove the tub and replace it with a piece that’s a shower bottom with a seat. It fits in the same spot and I can keep the tile around the bathtub which is fine. Then you buy a shower door. He can probably do it for between 1-1.5k. Much better than spending 10k for a tile walk in where they have to move plumbing.
