Stock Tank from Wikipedia- "Stock tanks are increasingly used as "rustic" backyard above-ground pools, or "stock tank pools" by retrofitting a filter pump and adding chlorine to keep the water clean throughout the summer. Metal stock tanks have also been used as a cheap alternative for a hot tub."
"In-ground pools are more expensive and require commitment than above-ground pools because of the excavation required to install the pool. The cost ranges between $35,000 and $65,000 for a standard in-ground pool with no bells and whistles", according to Home Advisor.
Stock Tank House- "A stock tank pool is a fun and inexpensive DIY option for the pool industry."
