Yes. Move the shower. But why move the toilet. It’s fine where it is. And will be the same on the other side... add that space to the shower ...

Agreed. Just feel bad taking tub out because has great jets and we both have back issues. Nowhere else to use tub because of size. But getting in and out of it will only get more difficult and my gut feeling is a curb less shower to get in and out of, not to mention a larger shower, will far outweigh the loss of the tub.
Thank you for your feedback! :D

If we take out the tub and make the existing tub area the shower, what would you recommend doing with the area of the existing shower stall size? We don't want to take down that wall dividing tub & shower. Built-in storage I'm thinking...?

The tub alcove will give you a nice, deep shower area. Is there another bathroom in the house where you can add a jetted tub? How about a hot tub on a patio? There is so much less water waste with a hot tub.

Your shower/closet can be made useful with the addition of pantry pull-outs like they sell for kitchens. You will have to have a filler piece on the end to allow it to open without hitting the windowsill, but it will be worth it to lose that couple of inches. No stationary closet shelves will be usable at the depth of a shower stall. You will “lose” things on the backs of the shelves and never see them again until you move!

Here us an example. You will probably need yours to be custom-made because of your extra depth.

Blum makes drawer runners that are 30” deep. How deep is your shower?

Nancy, agreed on the shelves! lol
We have another bathroom, but not bigenough for the jetted tub in master :(
Thank you!

Do you need the storage? Why don’t you want to move it? Maybe then do move the toilet. Unless you need storage I wouldn’t add.

Nancy, probably 30" or more. I will measure. Thx :)

HU-187528210,
Toilet move to existing shower would be a you-know-what big deal with drains and plumbing. Reason I thought of it was it would be more private there. Hubby is capable and competent, but we've been renoing our 1964 house and we're middle aged, and this is a retirement house in 3 years and he doesn't want to compromise messing with integrity of plumbing in case a home owner's insurance would be in order down the road, that they would question our doing it ourselves. He was a SeaBee in the Navy and has worked on commercial properties since the 80s. To pay for it would be quite an ordeal.
We both have bad backs and I'm a klutz. While I've dreamed of a tub like that all my life, but never had one, the real estate it takes up versus the actual present size of the shower, the potential difficulty of getting in and out of the tub just seems like a curbless or very small lip might be better an accommodation for advancing ages...

I hear you. Keep the toilet where it is.
