What about a wide shower chair that extends outside of the tub (over the tub wall - something like this)? Those are usually much more stable and easier to get in/out of. That particular model features a sliding seat, but there are also shower "benches" that are one solid piece if you can scoot across it? Not sure if that's still too difficult for you?
We used that - kind of messy because the shower curtain obviously can't hang down with the bench in the way, but if it's your only option, maybe throw down some extra towels and you're set?
If that doesn't work, how about no-rinse bath wipes? I know that costs money so it might not be a good solution, but throwing out ideas here, not sure what will/won't work for you?
I saw the PRETTIEST 3 compartment bag on Amazon. Link
To me it is reminiscent of some of the world when she was younger, maybe? Three pockets that can have different things. And this bag has been my go-to gift for everybody. The embroidery is so well done that six months of heavy use do not show at all. Some come with a second smaller bag, some don't.
The things that are most important to me as I start my cognitive decline are not driving, not getting to handle money, not being in charge of grown up things in my life anymore. I am not saying that toys are bad. But if you can afford to put some props in the wallet in the bag! A checkbook--talk to a bank, see if you can get one that has her name on it but no banking information. A pen with the bank's name. A calendar to keep "appointments" even if she can't really read/write anymore. A lot of good "remind me of being a functioning adult" stuff can be had for free.
We love Russian matryoshka dolls. (Fie on Russia now, though.) You can get plastic ones that aren't so stiff and hard to open and close.
She can decide what goes in her bags then.
You can get a bed alert pad similar to this one on Amazon, where if he shuffles off the pad or can get himself up from his bed, a little sound will go off to wake you up.
Just a suggestion to consider, but I think the button thing mentioned earlier might be better and more affordable for you.
Would laying a vinyl runner to cover the strip help at all? Not entirely positive I'm envisioning your problem right. Thinking something like this https://www.amazon.com/Resilia-Plastic-Protector-Non-Skid-Textured/dp/B07WC5MHDN/ref=pd_lpo_3?pd_rd_i=B07WC5MHDN&th=1 (there are other price options). If it was thick enough it might function as a mini ramp when laid over the problem area.
I have gone through exactly this with my Dad recently, also to the point of injuring my back.
You need to accept your limits. There are devices that can help you lift him, but don't be afraid to call the EMT's. My Dad just ended a month long hospital stay and the social worker was direct - if he falls or is on the ground and cannot get up, call the EMT's. 911. They will help get him into a chair or bed and you don't have to get any more help, don't have to go to the hospital, etc.
My Dad had lumbar decompression so he is walking very unsteady now. If that is similar to your dad look into a gait belt. Here is an example that is just like the one we use. You fasten it around his torso and slide your hand underneath to grip the belt on his back. This helps to provide stability when walking and also allows you to help control a descent if there is a fall.
Best of luck to you and your parents!
I would suggest a chair alarm, like this one:
Simple clip to the clothes, and keep the alarm box attached to the chair or bed. An awful alarm sounds if they get up/fall and the string pulls away. The end on the box is a magnet, so them pulling will activate it. 1)you will hear right away if they move 2) the alarm may startle them enough they sit back down before a fall, or at least stop trying after a few alarms 3) insurance may cover this item as it is considered necessary medical equipment for some fall risk patients-just ask their DR, caseworker, or or agency nurse.
Good luck!
I usually buy these for my Mother and they are pretty durable and cheap (in price not quality):
Amazon Brand - Solimo Flushable Adult Toilet Wipes, Fragrance Free, 126 Count
By Amazon.com
I'm a big fan of Google Duo. Very easy install, and once it's installed you can add a button to the homepage of your/their phone to start a video call. Very easy to use, and it has "fun" features too that sound silly but can really bring a laugh to a sad loved one (it sounds cheesey, but trust me, you'd be amazed at how often it works). It also allows you to easily send video messagesj, files, emojies and just to voice call.
This one might be an option as it can be controlled by voice commands like "turn up volume" "power off" etc plus it's only $40 on Amazon so if doesn't work it's not like you invested a lot of money into it.

This might be helpful for getting in and out the tub. We have one of the and it’s pretty sturdy and relatively cheap. Also you might want to look into getting a sliding shower bench that you sit and slid into the shower. DMI Step Stool with Handle for Adults and Seniors Made of Heavy Duty Metal, Holds up to 300 Pounds with 9.5 Inch Step Up https://www.amazon.com/dp/B000EWVP80/ref=cm_sw_r_cp_api_i_zYBpFb364WQJH
They make metal versions of those kiddie doorknob covers. Basically a metal "clamshell" design on a hinge. They usually have a lock and come with included keys. We bought a couple - they're about $25.00 on Amazon.
Edit - They're about $30-$35.00 now.

How about using a bed pull-up strap? You'd still do the heavy lifting, but if you strap that across the bed (instead of up and down), she can pull herself "up the hill" as it were while you do the actual heavy lifting to slide up her the board. You're still doing most of the work, but it could give her a greater feeling of control.
Consult with his doctor first!!!! Having cautioned that: Go for short(!) walks. Depending on his ability, just a walk to get the mail or the end of the street (depending on your geography) is a good start. Walking is great exercise - very low impact, but works all your systems, even at a low pace. And then while he's walking, you can not only walk with him to keep an eye on him (depending on his ability, you might want to equip him with a gait belt in case you need to catch/help him), but you can also talk with him - something that is also a big benefit!
If the doc says no to walking, ask them what your grampa can handle and/or what would be good.
