We just did a similar project Size comes into play - a walk in shower does not have to be the same dimensions as a tub/shower combo, so that can give you a little free play. And then you have to decide if you're going to buy a shower stall or create your own. You can buy shower liner, tile boards, and tile the entire shower. It sounds like you have a few decisions to make!

I am 47 years old and have had 2 strokes. I have difficulties getting in the shower/bath by myself. I would love to replace with the walk in shower only to create a spa like look. My small laundry room/1/2 bath is on the other side of the wall of the master bath. I would love to expand both.

We put one in the master bath nearly 20 years ago and it still runs fine, but it seldom gets used. We have 2 hot water heaters in our house; one serves the utility room and master bath and one for elsewhere. The jacuzzi depletes the hot water heater so by the end of filling the jacuzzi I'm running cold water. We recently redid our bath and I opted to keep it since it's the only "tub" on the main floor. During the reno we put in a new tub faucet and now the water runs in so slow it takes forever to fill. Now I wish we would have taken the jacuzzi out. We could have used the space for storage or something else.

Most three sided tubs will have a tile flange raising upwards from those three sides. That flange needs to be covered, or it will look pretty strange. That means building a small wall down on that end of the tub that comes up and wraps over the tile flange with tile. Maybe cap it off with similar material as your countertop. Could be a nice place to set a book or glass of wine will in the tub. If you don't want to build that short wall, take a look at other tubs that have an end. I believe Oceana Bathtubs has a couple.
