Spa Skimmers

Replace your spa's worn or damaged skimmer with a complete spa skim filter assembly from Waterway Plastics, Pentair, and Custom Molded Products. PST Pool Supplies stocks spa skimmer filters in 10–50 square foot filtration capacities, front-access and top-mount styles, for portable hot tubs and in-ground spas — starting from $129.30.

A spa skimmer serves two functions simultaneously: it skims surface debris (oils, hair, sunscreen, and floating particles) from the water surface while also housing the primary filter cartridge that removes fine particulates from the spa water. The skimmer's built-in filter housing eliminates the need for a separate external filter canister in most portable spa designs — making the spa skimmer the most critical water quality component in the filtration system. The key products in this collection: Waterway DynaFlo Lo-Profile skim filters (40 sq ft and 50 sq ft, gray) are complete low-profile skimmer assemblies designed for portable hot tubs with limited installation depth in the cabinet wall — the lo-profile design fits where standard-depth skimmers cannot. The DynaFlo Plus (50 sq ft, gray) is the higher-capacity version of the same platform. Waterway Front Access skim filters (10 sq ft and 20 sq ft, side wall) use a front-access door design — the filter cartridge is accessed from the front face of the skimmer (inside the spa) rather than from the top — eliminating the need to open the spa cabinet for filter service. This design is common on spas with limited access below the waterline. Pentair Rainbow DFML series skim filters (25, 35, and 50 sq ft, top-mount) are top-mount skimmer filter assemblies for spas where the filter is accessed from above — common in in-ground spa installations. The CMP top-mount skim filter (25 sq ft, 2\" slip) provides an alternative top-mount option with 2\" slip plumbing connections.

When selecting a replacement spa skimmer, confirm: (1) filter capacity (sq ft) — larger spas or higher bather loads benefit from higher sq ft ratings; (2) access style (front vs. top) — must match the existing installation for cartridge serviceability; (3) plumbing connection size (typically 2\" slip or spigot); and (4) overall dimensions — the skimmer must fit the existing cutout in the spa shell.
