No just soak. No eating or drinking.
I don’t know, maybe I have a higher heat tolerance than you. That 20-30 minute bath of yours would be too cold for me after about 5 minutes then it would be uncomfortably cold when I get out. An extremely hot shower with a good shower head is better for me.
Agree w @Loach.
A bath is hot enough to enjoy only as long as hot water is running continuously to replenish the vast heat loss. Which means it ends when the HWH tank is empty. Or actually well before that when the hot water input becomes tepid.
On the occasions I’ve tried it, I get out of a “hot” bath chilled through. Because the hottest it can be maintained is well below the temp that adds heat to my body, not saps it away.
Then again, I’m pretty much skin & bones; neither of which generate much heat on their own. 
My body is constantly creating heat. I don’t need a bath to “add heat”. I’ve done brief stints in hot tubs that were actually hot. It’s fun as long as there’s a cool shower nearby. And water to drink, as my body frantically tried to cool off by sweating, which is course is useless, but leaves me a little dehydrated.
The ideal is bathwater that maintains your body temp, which is at or barely lower than body temp.
I renovated my bathroom to add a big tub, big enough to cover an adult with water. But the angle at the back turns out to be wrong, and it’s not really comfortable to sit in, at least for me. I wish I’d tried harder to get a Japanese tub. (Deeper and shorter. You are expected to sit in it with bent knees.) At least my husband likes it. He soaks regularly, maybe weekly.
I like to read when i do take a bath. My Kindle is waterproof, but i got good at keeping books dry in the bathtub. That includes both a dry spot to rest them and a dry washcloth just to dry my hands between dipping hands in water and turning a page.
This may sound sacrilegious, but I never take baths, just showers. I sometimes take showers as long as twenty minutes, though, so I guess that’s the shower version of “soaking”.
IME, nowhere near continuously. I usually top up the hot water briefly, once or for a really long bath maybe twice.
Maybe your bathroom is extra cold, or you don’t start off with really hot water in the first place?
Hmmm. Maybe that’s connected. I am certainly not skin and bones. But I suspect that you’re starting with water I’d consider lukewarmish.
I generally get out of the tub hot enough to stay warm through letting the dry skin cream soak in afterwards.
I keep the thermostat in my house at 78F year round. Summer or winter. Anything less and I’m cold while fully dressed. It’s a curse.
Eeek!
It’s a good thing we don’t live together!
I generously offer to be a fat donor, although you’ll have to arrange extraction and transplantation! I have a solid 30-40 lbs of fat that I’ve been slowly getting rid that I’m sure would love a good home! 
My cheapness keeps the house at 75 in the Summer, and 68 in the winter. Generally I want it right around 71, but my wife would prefer 73-4 year round.
Back to the thread, as I said, my wife loves her hot baths, to the point where she’s turned the “new” (now 4 year old) water heater up to the first “overheat” setting. And she’ll soak, draining a bit of “tepid” water and adding fresh hot every 10-15 minutes for an hour long soak.
I nearly always listen to podcasts whenever I shower or bathe. I haven’t really done baths in a long time, though. I don’t think our current tub even has a proper drain plug.
Water here is cheap and plentiful, so I’m ore likely to take a long shower. Reading or watching things isn’t practical, but listening is.
I shower, and live in Arizona, where water should be conserved, so my showers are kept short. But sometimes in winter I’ll take a long hot shower, and I’ll plug my ears and listen to the ‘rain drops’ hitting my head.
The web name used by the OP is a great one: SurrenderDorothy.
Substitute plugs, requiring no installation other than shoving them in the hole (and pulling them out again when you want the water to drain) are generally available at hardware stores and often even in the hardware section of groceries.
(Admittedly, it doesn’t read as if that’s what’s stopping you from taking a bath.)
Wow!
Yeah! I can’t get to sleep when it’s that warm. I set my AC to 72 for two hours right at bedtime so i can sleep.
I think my favorite temp for lounging around is ~73 and when I’m active, I’m happy with temps down to perhaps 50 in light clothes, and of course with warm clothes i can be comfortable in cold weather.
I’m curious, do you have trouble stepping into a shower? I always cringe a little when i step into the shower, and many are hard to adjust the temp without standing in the flow. That’s one of the reasons i have a hand-held shower, so i can hold it away from me until I’ve adjusted the temp.
After years of practice in hotels, I’m good at setting the temp of the running water by sticking just a finger into the flow. Here at home I know where to set the handle from the git-go then just wait until the water is up to a stable temp before jumping in and I’m confident it’s the right one. Which temp some folks (ex-spouses perhaps? ) claim will give them burns; it’s pretty hot.
Getting in is easy as long as I promptly get fully wet & keep the spray coming.
Getting out is another matter. Once the water is off I transition from toasty / cozy to cool to uncomfortably cold long before I can get dried off & dressed. Getting the bathroom steamed up to 80-something helps mitigate that.
I’m just built about 10-15 degrees offset from everyone else. PITA.
We keep the house at 69F year-round. Except for the bedroom. My wife put in a separate air conditioner so she can sleep at 60-62 at night.
I think it’s not connected that my hands are cold all the time so sticking them in a warm bath suits me just fine. (I then dry them off and reach for my book.)
And like most people I just add a bit of hot water if the bathwater cools down. Easier than sticking the whole bath in the microwave.
Probably younger than that for me. Maybe 8 or 9? I don’t even have a tub in my townhouse anymore. My sister’s en suite has a stall shower, and mine came with a tub with shower in the tub area. When we remodelled, I had them take out the tub, put in a biggish shower with a bench to replace it. Added a grab bar. I’m short, and even before I removed the tub I’d occasionally stub my toe stepping out of the tub. Trying to age in place.
I bathe most days. Usually with a paperback, sometimes with an audioook on the Sonos speaker. Once a week or so, I use rose or eucalyptus scented epsom salts. There’s a sturdy grab bar.
Before taking a post-gardening bath yesterday, I grabbed a book from the reading pile. It’s a copy of Girl with a Pearl Earring and I can easily bend back the pages and hold it with just one hand. Very handy for the bath.
Had to add quite a bit of hot water - that’s the problem if the book is good. 
That happened to me with Station Eleven.
As a teen, I read all of Narnia in the tub one weekend. I therefore learned that my father had done the same as an adolescent.
