As of November 2015, plans for outdoor pool houses are available for download at the websites for Summerwood Products and The Backroad Home. Both sites charge fees for the plans.
Summerwood Products offers several styles of pool houses. For example, the Catalina pool cabana is five-sided and ranges in size from 56 to 350 square feet. The Dune pool house is a contemporary style with concealed double doors. Plans are customizable.
The Backroad Home has both cabanas and shed plans available for one price. Recommended pool house designs include an octagonal shed with a monolithic slab foundation and an Old West-style saloon.
