Bath Tub Terrors

I have but one person...er...monkey to thank for the trauma we've all been faced with these last few weeks. Yeah, Curious Geourge, im looking at you.
Okay, but seriously? What kind of writer came up with the idea to make an episode featuring his bath toys getting sucked down the drain? Clearly one who doesn't have children. I can completely understand why she would be afraid of said episode, but i never thought it would escalate to this.
Bath time is a series of struggling, screaming, terrifying and traumatizing events. No joke. It. Is. HARD. Of course we're also into the most messy season of all...summer. Mud, grass, dirt, sand...you get it. She gets dirty. Dirty = BAD...real bad.
The mention of the the words "bath time" send her into a full out freak out. When i do get her in the bathroom, she sees her toys are in there, the plug is in...still a no-go. I tried getting my baithing suit on, getting in, playing, splashing -- a good 'ol time (for me). And as she stands --on the outside-- watching, she still isnt comfortable enough to even get in. Please note: the screaming-crying fit hasn't subsided yet.

Regardless, my child needs to be cleaned. Unfortunatley, i have no choice but to go against her will and plop her in, lay her down and soak her hair. At this point screaming has turned into something of a growling hoarse shriek and i feel like a completely terrible person, let alone mother. Once we're done i pull the plus and she gets into a fit again...er, i guess it never ended, but you know what i mean. She's freaking the heck out. I try showing her that her toys nor my hand or anything except water can go down the drain. Well, she couldn't care less. She wanted the heck out of there. so, i got her out. She was shaking. I felt even worse! If that was even possible. Apparently it was. I brought her in my room and talked calmly to her explaining that her toys are okay. They're too big to go down the drain. ONLY water goes down there. She sort of --in toddler language-- repeated everything i said followed by a sweet, heart melting "okay mommy". I could of cried.
Im so terrified that this is going to turn into some kind of phobia or something. A phobia of water or the tub or...i don't know...anything that can be related.
When i was about 4yo i lived with my parents in a small apartment. We only had a stand-up shower. I hated it, but what else could my mom do? I had to get clean. I still remember sitting on the shower floor crying. I was traumatized. I think it may have been a  year later that we moved. I never took another shower until i was almost 15 years old. I was just uncomfortable. I'm ok now, obviously. But still, i fear for Leah. I was thinking maybe i could try sitting her in our kitchen sick, since its big... or just doing sponge baths until she has some time to forget about this theory she has.
Help a sista out. Any suggestion peeps??
