Garden Leisure and Shoreline are two brands owned by SCP Distributors and Superior Pool Products respectively - both are wholesale distributors in the industry.
Tatum had been the manufacturer for SCP and SPP for these spas. However, they have just lost them to Dynasty. Dynasty was the original manufacturer for SCP and SPP for these brands.
In speaking with a higher up in PoolCorp (Parent of SCP and SPP) they were not at all happy with the quality Tatum was putting out there or in the way they were doing business.
