New Title

Ready for a pool built around serious swimming, diving, and active water recreation? Reach out to New England Fiberglass Pools to explore The Mariana, a fiberglass inground pool inspired by the depth and mystery of the Mariana Trench. With a dramatic 8-foot deep end, a 40-foot length, and an extended swim corridor, this streamlined design provides open water for exercise, diving, recreation, and relaxation.

The Mariana's 8-foot deep end provides substantial depth for diving, underwater games, and a more immersive swimming experience. Its extended swim corridor creates a long, unobstructed lane that's ideal for lap swimming, exercise, and active water play. At the shallow end, an entry relaxation bench provides a comfortable place to sit, socialize, or supervise younger swimmers. Clean lines and a balanced layout give The Mariana a modern appearance while maintaining the deep-water functionality that sets it apart.

The Mariana is available in one spacious configuration:

• 40' × 15'6" — 4'0" shallow end to 8'0" deep end

This generous footprint provides substantial swimming space while maintaining a dramatic deep end. Choose from eight premium gelcoat finishes to personalize the appearance of your pool: Abyss Blue, Glacier Blue, Summit Silver, Tropic Cyan, Drift Sand, Illuminating Sky, Surge Grey, and Stellar Black. These finishes are designed to provide lasting beauty while adding shimmer, depth, and character to the water. Optional Therma, Sanctuary, and Cove spas can add another space for relaxation, with spillover features available to create an attractive waterfall effect. Crest, Vista, and Shoreline tanning ledges can also provide shallow-water areas for lounging, children's play, and additional visual appeal.

The Mariana is an excellent choice for homeowners who prioritize deep-water recreation and generous open swimming space. While The Sequoia offers a similar 40-foot length and 8-foot depth with a wider footprint and wrap-around bench, The Mariana provides a streamlined 15'6" width focused on maximizing open water. Compared with The Aurora's flat-bottom versatility, The Amazon's freeform design, The Sacred's integrated resort-style features, The Niagara's infinity-edge aesthetic, and El Capitan's balanced mix of tanning and seating areas, The Mariana stands out as a swim-focused design built around depth and active recreation.
