Taking a bath... in a SMALL tub ?

once in a while I want to take a nice herbal tea and honey bath. But frankly my tub is quite small for... a bath. To give you an idea, my momster and I live in an apartment of sorts and the bedrooms are the perfect size for a child under like 10. The tub is fine for taking showers in, but with baths, it's weird because if I sit straight up / lean back, I'm cold. But if I lay all the way down, my knees and stomach stick out and I look like a whale that's about to come beached.
