You know..... there is likely no cement board or tile below the line of the tub

There is such a thing as a 'tub cut' but I don't know if they can do it to a porcelain tub.

Of course, this creates other issues for keeping the water contained in the tub with a door or curtain.

I would keep things as they are and spend the money on a chic pair of glass doors.

Sorry if you want a shower and no tub this will be a gut job in that space . That is the only way to ge the waterproofing for a shower . Once you start you will realize the other tiles are not working either so a big can of worms to open to get a small reward. You have a shower you will gain little by what you pan. At most maybe a glass shower screen right now but for me the burgundy tiles would have to go

Great bathroom!

totally just my opinion but I am thinking the lack of storage and counter around the sink will become a bigger pain point then stepping in and out of the shower - I’d wait on any changes to see how you all use the bath (my bet is you will want to completely redo it in the not too distant future)

Great bathroom, use it for a year or six months to see what changes you want to make. The waterproofing will be broken if you remove the tub, as Patricia Colwell points out.

" would like to replace the tub with a shower but try to save the shower tile. Is there anyway that could work? "

Unfortunately to remove the tub will require redoing the shower as a whole. Guaranteed there is no waterproofing there now and you need to waterproof the entire shower properly or you are throwing good money after bad.

Thank you to all who responded. I suspected that to remove the bath we would need to replace the whole shower. Moving on to full remodel. Thanks again.

I'd bet that those are Passion from American Olean, and Desert Gray from Daltile. Same maker, same tile, just different labels. You could probably keep the tile in the room, and do a new shower, with the arch, with the same colors that exist there now. It would look original to the home. Get some samples, and start planning.

I would definitely keep the tub and shower area as is, but I would remove the glass block window. I've never been a fan, although I know it was used a lot during that period. I'd replace it with a window that matches the rest of your home (so not necessarily the style I've got pictured). I'd remove the cabinet above the toilet and replace with one that come down lower over the tile to help soften that line between tile and painted area. I like the black/dark wood in contrast to the color and brightness of the room as it is now.

I also don't like that the accessories (toilet paper holder, soap holders, etc.) are in red. I would use a tile paint that matched the light gray and paint over them, so they don't stand out so much.

Replace the light fixture and faucet to update the look.

I would also remove the bath rugs and get one area rug (probably a soft textured neutral cream color rug) to replace them with.

I wouldn't do glass doors. Select a nice shower curtain with a separate liner that will soften the harshness of all the tile. You could do decorative drapery panels on each side. Two rods are needed for this and have the decorative panels go from the bottom of the arch all the way to the floor. Use a white rod where the current one is and place the shower liner on it. Above the arch use the two drapery panels. (see pic for idea).

I love that red tile floor! It's beautiful!

At first I gagged at the site, but if you change the window to regular window as suggested and then wallpaper the bathroom in a very pretty pattern with that brick red, it could totally transform that space even with leaving the tile. I think leaving a tub under the shower is best in this situation unless you or your husband have mobility issues.

Sounds like a walk in shower is a priority and you are ready for a full gut. There are still plenty of ways to gut this room and still use some retro feeling finishes.

I'm wondering if you can get a wall hung vanity with storage. In a small bathroom wall hung vanities really increase the perception of the size of the space. However, your wall register may need to be moved. Have you looked into that?

The window and the floor are the biggest eyesores…changing them and finding a better spot for storage…(removing the cabinets above) …

Would be the shortest way to a well functioning bathroom

In any case ….the space now taken by the tub…is way too shallow for a comfortable shower
