The C Series is the larger curved freeform pool in the River Pools lineup. Soft curves rather than corners, a generous tanning ledge molded into the shallow end, an open swim interior, and a deep-end bench for cool-down seating. Two sizes: the C35 (16' × 35') and the C40 (16' × 40'). Available in all six River Pools gelcoat finishes. Seven Seas Pools & Spas builds and services the C Series across our region.

What makes the C Series distinct in the River Pools lineup: it is the largest curved freeform pool River Pools makes. The I Series tops out at the I34 (15.5' × 34'). The C40 stretches to 16' × 40' inside a curved shape, which gives you the architectural softness of a freeform pool at the scale of a full-size rectangular shell.
Explore the River Pools C Series with Seven Seas Pools & Spas and compare the layout, gelcoat finishes, and installation details before you decide.
| Model | Dimensions | Tanning Ledge | Deep-End Bench | Auto-Cover Ready |
|---|---|---|---|---|
| C35 | 16' × 35' | Yes | Yes | No |
| C40 | 16' × 40' | Yes | Yes | No |
The C35 and C40 share the same feature mix. The C40 adds five feet of length, which extends the open swim interior between the tanning ledge and the deep-end bench.
The C Series tanning ledge is the largest tanning ledge in the freeform River Pools lineup. The ledge sits at the shallow lounging depth, holds multiple lounge chairs side-by-side, uses a slip-resistant gelcoat surface, and shares a spillway edge with the main pool so the water level reads continuous.
Typical ledge add-ons you can order with the install:
A built-in bench in the deep end gives you in-water seating after a swim. The bench is molded into the shell at the same time as the tanning ledge.
All six River Pools finishes are available on both C Series models:
Arctic
Caribbean
Diamond
California
Maya
Sandstone
Both are freeform with a tanning ledge and deep-end bench. The I Series offers an integrated spa on the S models; the C Series does not. The C Series is the larger curved shell (16' × 35' or 40'); the I Series tops out at 15.5' × 34'. Pick I for smaller curved or for the integrated spa; pick C for the larger curved footprint.
Both have a tanning ledge and a deep-end bench. The D Series is rectangular and auto-cover-ready; the C Series is freeform and not. Pick D for the rectangular plus cover combination; pick C for the curved shape.
Both have a tanning ledge, a deep-end bench, and a non-rectangular shape (curved or Roman-end). The C Series is fully freeform; the L Series is Roman-end (rectangular body with a rounded entry on one end). Pick C for fully curved; pick L for transitional Roman.
Seven Seas Pools & Spas can walk you through the model sizes, gelcoat color options, decking, equipment, and installation details before your project moves forward.
No. The freeform coping geometry is not engineered for hidden cover tracks. A safety net or a manual mesh cover is possible; an automatic safety cover is not.
Not as an integrated feature of the C Series shell. A standalone hot tub beside the pool is the cleanest path. Many C Series installs include a Hot Spring or Caldera Spas hot tub on its own pad.
No, the C Series uses a conventional deep end. For a divable shell, pick the T Series T40 (8'6" deep end).
No. The shell is delivered as a single piece, the same way every River Pools shell is delivered. The excavation is the same one-day process. The decking around a freeform shape is a different layout from a rectangular pool but is not more complex from a construction standpoint.
The C Series is the right answer for yards where you want a large freeform pool with a real tanning ledge and don't need an auto-cover. Call or stop by your local Seven Seas Pools & Spas to walk through gelcoat samples and see installed C Series galleries from yards near yours.
