Q&A: Bathtub Water Garden
Answer: If you plan to sink the tub into the ground, it should serve quite well as a pond. If it's above ground, consider it a warm-season garden ornament because the water will freeze hard during the winter and kill your plants. The tub can stay white, but expect it to turn green with algae growth within a year. Pond liners are black because they fool the eye into thinking the water is much deeper than it really is. It's an aesthetic thing, rather than a functional thing. Most any water plants will do okay in your tub, but some aquatic plants require a water depth of four or more feet in order to grow well, and to be able to winter over. A layer of ice on the top of the pond in winter won't hurt plant roots that are several feet below the surface, but a shallow pond will freeze completely and may kill the plants. Enjoy!

pond plants
Just to let you know I have a pond that I built myself deepest end is 4 feet deep shallowest end is only 2-3 inches I have marginal plants as well as some that are in the bottom of the pond lily pads iris ect.. I have lost nothing in the 3 yrs it has been in I leave my fish in all winter long as well I am in zone 5. I do however have a cow tank heater that I put in when it starts to freeze shut I shut off all pumps and leave them in the water as this way thye dont dry out and easier to turn back on in the spring. I hope this helps you many plants can winter over just be sure y ou are buying for your zone and Good luck you wont be disapointed I spend many hours in a week out by mine. Have fun and enjoy.

Pond Plants
I have two 18 inch ponds now for 10 years. I simply cut my plants off very close to the pot top and sink them. My pond freezes over while my pump continues to flow under the ice. It freezes in a volcanic shape and flows the entire winter. I have never lost a plant in my 18 inches of water. This is my experience so I don't know if this will work for everyone.
