The Blue Wave Trinity 33' x 18' oval resin above-ground pool (model NB1851, SKU PST-NB1851) pairs a taupe 52" steel wall with a resin frame of 7" resin top seats, 6" resin verticals and 1" resin top and bottom rails. The wall, frame, hardware, plastic edging and a wide mouth skimmer with return come in the box, so you choose the overlap liner, filter system and ladder that suit your yard.

Why PST Customers Pick This

Resin Frame

7" resin top seats, 6" resin verticals and 1" resin rails meet at resin top and bottom joints, with seat covers and caps to finish the look.

Taupe Galvanized Wall

The hot dipped galvanized 52" steel wall is 0.46 mm thick, finished in taupe with protective wall coatings, and holds roughly 14,018 gallons at a normal fill level.

Overlap Liner Ready

Fold an overlap liner over the top of the wall, clip the included plastic edging over it, and the top rails go on above.

Skimmer In The Box

A wide mouth skimmer and return come with the pool, ready for the filter system you choose.

Braceless Oval Frame

Side verticals with a factory fitted skin, horizontal supports, pressure plates and tension straps hold the straight sides of the pool.

Do It Yourself Setup

The instructions walk you from site prep to a finished frame. Plan one full, calm day with 2 or 3 people on the job.

Frequently Asked Questions

What comes in the box?

The taupe 52" steel wall, the resin frame with its joints, seat covers and caps, all assembly hardware, plastic edging and a wide mouth skimmer with return. The liner, filter system and ladder are sold separately, and the instructions call for an earth cove around the inside of the wall before the liner goes in.

Which liner fits this pool?

Choose an overlap liner sized for this 33' x 18' oval pool with its 52" wall. The liner folds over the top of the wall and the included plastic edging clips over it before the top rails go on.

Can I install it myself?

Yes. The instructions call for 2 or 3 people and a full day, so start early and skip windy days. Plan on removing all sod, getting the ground firm and level, raking a sand base and building an earth cove around the inside of the wall before the liner goes in.

What does the warranty cover?

The 30-year limited warranty covers the pool wall and frame components. The liner, filter, pump, ladder and skimmer are not covered by the pool warranty, and the pool must be set up above ground on level ground, following the instructions.

Do I keep water in the pool over winter?

Yes. Keep the pool filled through the winter. In areas that freeze, lower the water to about 6 in below the lowest skimmer opening, then hold that level steady. Snow and ice on a winter cover need the water underneath for support, and the pool should never be left standing empty.
