A contractor can install a tub that you had made to order at a company but would not be able to make one for you. That you will have to contact individual companies to find out.

Depending on where your problem/s are as you noticed on most of this type of products only a little water is ever put in the tub. You may need to think about the cost of the water depending on the size of the tub. An alternate suggestion is if there is one in your area and it is kept clean enough find a gym or some type, we used to use the one at a Y, with a lift that can be used to lower people into a hot tub.

One thing I did notice was that the latch to lock the tub in one picture was on the outside and in another on the inside. In leg stretching you would not want one on the inside.

Thanks maifleur but no gym please - I want the tub at home - and water is not a concern. Also note I added to the P.S. after your response, so i see tile can be problematic, but some of those respondents did seem to offer solutions, and i'd be curious what anyone here thinks of those solutions.

Another solution may be for a contractor to just build the entire toilet area on a platform, to more easily step into a deeper tub?

Is that feasible? This world is so full of booby-trap setups that i can never climb out.

Do not do the tile. While it sounds good eventually it would leak. You did not say where you would need the entrance. While they are probably more expensive nursing homes use large walk in tubs with jets. Think beyond today to the time that you might need assistance in getting in and out of the tub. Most of the pictures I just looked at the entrance is very small.

The one where my husband was at looked like it was many years old but you could contact a local nursing home to see if they had one that they could provide you with a product name. The one that was used had a multipart door that was wide enough to wheel a chair into, transfer the patient to a seat but big enough to use for water therapy.

Be aware that with a walk in tub you have to get in before filling and wait for it to drain before getting out. So be sure you have enough heating or plenty of warm towels to wrap up in.

Could you put in a Shower stall instead of a tub so you can sit on a stool and stretch or does it have to be an actual tub.? It does have to a a walk in, correct?

You might consider a large soaking tub with a lift if you can't find a way to use a walk-in tub. I added a lift to my mother's existing spa tub which has worked well for her.

As a PT, I don’t think you are going to get a sufficient answer on this unless you can get someone to measure your sitting leg length and the space you want/need to occupy in the tub. Every 5’ person doesn’t have the same leg length/pelvis size and won’t take up the same amount of space in a seated position. (We call it long sitting when the legs are fully extended)
Do you see a doc or PT frequently? If so, have them measure your long sit position, or ideal “stretching” position to use your terms, and compare to the base of the tubs you are looking at.

What about my above platform idea? I don't want a lift. Also I don't even know yet exactly where the opening would have to be to correspond to my "set-in-stone" access point. Suffice for now, that it's a probability.

Much obliged for the insider stories re: walk-in tubs!

To Dedtired, it does not have to be a walk-in as long as I can comfortably enter & exit. Re: shower stall that's an idea, however, my damaged body needs constant stretching-in-bath "maintenance", as shown at 1:42 on video in my OP.

...Believe me, I don't need the luxury of fancy jets & bubbles. Rather just a bath like they did back in the old days. Look, i'm not saying the jets don't increase the therapy, of course they do. I've been in sauna's so realize that. But every added thing is expensive.

To ravencajun, of course I'd love to stretch out in a 5' tub. Unfortunately that will not be an option. I require space-efficiency, and so need to cut down to 46".

To NYCish - i explained that I can sit on a 13" high stool at edge of a 46" shower with my spine against the wall, and have room for leg stretch with room to spare. So that should have explained alot to anyone in the field. Note it's 46" internally, from front wall to rear wall.

The problem is, that these tub companies fail to state the height of the built-in seats, and the length in inches from rear of seat, till the opposite side.

If there's a suitable walk-in tub, who needs to ever open the tub door if a platform is built as stated in above post?

P.S. Please see below attachment - seems its on pinterest.

I would actually attempt to get hold of a brick-and-mortar store that offers floor model tubs. They might be accommodating and measure for you the actual internal length of the tub.

I also wonder if you could get a regular tub and use a transfer chair. I prefer the swivel slide transfer chairs but there are basic ones as well. That you could use a second basic transfer chair to stretch your legs out onto and wash with a handheld showerhead on a hose.

In my humble opinion you might not get exactly what you want easily. Particularly without spending a good amount of money. But you might be able to get something fairly close. Good luck!

Below is a UK site that you might want to at least peruse if you go with a shower or regular standard tub and chairs Etc.

I see, thanks. (Though depressed!) I perused the link.

Thank you for that link. It did give some very good suggestions. I did find the shower toilet interesting as I lived in a house that was built in the 1930s which had one of the bathrooms similar to it that was original to the house. The woman who used it kept the toilet paper outside because the holder allowed the paper to become damp.

Here's other ideas of what may be suitable, running the gamut of 1200mm to 1700mm I believe.

A lot of people who need water-based therapy go with a swimming pool, seriously. Look at Crestwood's above-ground models or, on a smaller scale, a spa, hot tub, or swim spa combo. It would be an investment in your health and more accessible as a permanent set-up than a bathtub that needed to be refilled daily with no way to keep the water warm once filled. Your sessions could be longer and more frequent with a real pool or spa.

Before investing in a hot tub the OP needs to have a sincere discussion with their doctor. While there are some of the things mentioned that warm water can help varicose veins may preclude the use of a hot tub or spa. Reason I mention this was a sign that was above the hot tub at the Y which mentioned several reasons not to use it without doctor's permission. The OP may have already discussed this with their doctor.

Hi, if you don't mind, because I've semi-resolved this (see my last two pics), I'm starting a spin-off question re: sourcing etc.

Please don't be medically concerned, because i do bath therapy all the time, and i know by now what's therapeutic for my condition - ginger+eucalyptus+marjoram bath salts rubbed into my problem area's while immersed in a warm bath. (Interspersed periodically with letting cool water flow down onto my feet/ankles/legs.) I need to take such baths prior to trekking out of the house.
