Covington-based Pool Corp. reported third-quarter earnings climbed to a record $34.8 million, or 78 cents per share, compared to $32.3 million, or 68 cents per share, a year earlier.

The swimming pool and products wholesaler boosted sales by 6 percent to a record $615.5 million. Those results were driven by pool replacements and remodeling, which fueled the company’s record results in the first half of the year.

President and Chief Executive Officer Manuel Perez de la Mesa said the continuing demand for “discretionary products” — the building materials such as tile and lighting for outdoor living areas — rose by double digits, boosting overall sales.

Pool is tightening its 2014 per-share earnings forecast to a range of $2.38 to $2.43, Perez de la Mesa said. The company had earlier projected a profit of $2.35 to $2.45.

Pool has 329 sales centers in North America, Europe, South America and Australia and distributes more than 160,000 products to more than 80,000 wholesale customers.
