The timber provided to the River Baths project originates from the same source as that recently supplied for the Thingvellir National Park pedestrian facility reconstruction project. It was harvested from Haukadalur National Forest, where a spruce stand required preemptive regeneration following initial site preparation. The regeneration strategy will prioritize natural processes, supplemented by seedling planting as necessary.

Assistant Forest Manager Jóhannes H. Sigurðsson and Forester Magnús Fannar Guðmundsson collaborated on timber selection and processing last autumn, concluding with planing and painting.

Forest Manager Trausti Jóhannsson highlighted the project's educational value, emphasizing the rigorous selection process necessary to achieve quality standards. He stressed the critical importance of consistent forest management practices throughout the entire growth cycle, noting that simply planting and waiting 60-70 years for mature timber is inadequate. Effective pre-commercial thinning in the early stages, along with supplementary planting as needed, multiple top cutting, and other best management practices, are crucial for optimizing timber value while enhancing overall forest yields and harvesting efficiency.

Construction of the Laugarás River Baths commenced last spring, with a projected opening date of Summer 2025. T. Mark architectural agency designed the lagoon and its associated facilities; Mannverk construction company managed the project's construction and project design. The lagoon will be situated near the Iða pending bridge in Laugarás, adjacent to the Slakki zoo. The estimated cost is approximately ISK two billion, with projected annual visitor numbers ranging from 150,000 to 200,000.

The bathing area will feature two pedestal-based saunas, heated using locally sourced geothermal energy from a village spring, and a cold pool utilising locally sourced glacial water. In line with this commitment to local sourcing, investors mandated the use of locally sourced timber for construction. Land and Forest Iceland is supplying this timber, harvested from Haukadalur National Forest and processed in Thjórsárdalur.
