Blue Wave Trinity 33' x 18' Oval Above-Ground Pool Package
A resin-framed pool with liner, filter and ladder.
The Blue Wave Trinity 33' x 18' oval above-ground pool package (NB19916) sets a 52" steel wall inside a resin frame of 7" resin top seats, 6" resin verticals and 1" resin top and bottom rails. Along with the pool and its widemouth skimmer and return, you get a standard-gauge overlap liner, a Sandman 22 in sand filter system with a 1.5 HP two-speed pump and a resin A-frame ladder. A pool maintenance kit is not included.
Why PST Customers Pick This
Matched to This Pool
The overlap liner is cut for the 33' x 18' oval pool, and the Sandman 22 in sand filter system is the size paired with it, so there is no separate liner or filter sizing to work out.
Resin Frame Components
7" resin top seats, 6" resin verticals, 1" resin top and bottom rails and resin top and bottom joints frame a 52" steel wall with a 0.46 mm wall gauge.
Sandman Sand Filtration
The Sandman system mounts the filter tank and 1.5 HP pump on one base. A 6-way valve with settings including filter, backwash, rinse, waste and recirculate, plus a pressure gauge and sight glass, keeps routine care straightforward. Filter-grade sand is sold separately.
Resin A-Frame Ladder
The resin A-frame ladder has outside steps, an in-pool ladder, a top platform, handrails and an anti-entrapment barrier. Take the ladder out of the pool whenever the pool is not in use.
Braceless Oval Frame
The braceless oval frame adds skin-covered side verticals, horizontal supports, pressure plates and end and middle straps for the straight sides of the pool, with no outside braces.
About 14,018 Gallons
The 33' x 18' oval pool holds an estimated 14,018 gallons, figured from its size and wall height. The actual volume depends on how high the water is filled.
Electrical Safety
Plug the filter pump only into a grounded outlet protected by a GFCI, and have a qualified electrician install it. Keep the pump's power cut-off within reach, and keep other electrical devices at least 8 ft from the pool.
Specifications
Frequently Asked Questions
What is included in this package?
The Trinity 33' x 18' oval pool with its 52" steel wall, frame, hardware, plastic coping strips and a widemouth skimmer and return, plus a standard-gauge overlap liner, a Sandman 22 in sand filter system with a 1.5 HP two-speed pump and a resin A-frame ladder. A pool maintenance kit is not included.
What else do I need before I start?
Pick up filter-grade sand for the sand filter, a backwash hose and pea gravel to fill the ladder legs, since none of these come in the package. The ladder instructions list its mounting bolts, washers and nuts as not included, and recommend a ladder pad under the bottom step to protect the liner. The site needs level, firm ground cleared of grass and sod, a patio block under each bottom joint, cinder blocks set level under each side support, sand for the pool base and cove, and a grounded 110-volt outlet with GFCI protection for the pump.
Can I install it myself?
Yes. The pool, liner, filter system and ladder each come with step-by-step instructions. On an oval pool the side supports are set level on cinder blocks before the wall goes up. Start the wall on a calm day when you have the whole day free, bring a few helpers to handle the steel wall, and have a qualified electrician install the GFCI outlet.
How do the warranties work?
The Trinity pool carries a 30-year limited warranty on the pool wall and frame. The other components are backed separately: the sand filter system by a 1-year limited warranty, the standard-gauge liner by a 15-year pro-rated liner warranty and the ladder by a 3-year limited warranty. The written warranty documents set the full terms.
How does the included liner install?
The standard-gauge overlap liner drapes over the top of the wall and is held in place with the plastic coping strips, and it is made for walls from 48 in to 54 in. Unfold it in the sun first so the vinyl warms up and is easier to position.

Let customers speak for us
Great company to work with!
Came in great condition my kid loves it, fit perfect hes 6 and got a medium.
Order received. Thank you
This is a well built spa light with excellent cables and excellent customer service. Highly recommend
New flow switch worked perfect. Much cheaper than other sites. Arrived on time.
Good price works great!
Extremely fair company. Cares about their customers and are willing to do what it take to make you feel satisfied!
Dog chewed pool robot cord end. Ordered this fix it. Delivery was a little slow and I think some instructions should have been included as should have been a tiny allen wrench needed to tighten the wires into the plug. I got it done but think most homeowners would have a problem doing it. Other than these issues, the plug works fine and was much cheaper than buying a whole new cord.
Had a minor issue with pricing of a separate part in my order, but the sales team was responsive and reasonable, and worked with me to come to a mutually agreeable solution. In a world where character and reason has become the exception rather than the norm, they stand by their word and were committed to finding a fair solution.
I highly recommend them, and will look to them first in the future when searching for pool and spa products. Thanks, Sal and team!
I really like it
The part fit perfectly. Shipping was quick. Would definitely purchas from PST Pool Supplies again in the future.
Ordered this as I just had a leak and replaced it with a complete flow switch and valve . If the valve body cracks again, at least I am prepared. Thanks!
Awesome product and handling. It fit where my IC40 was easily.
We found the hard to find parts here, and they were delivered all the way to North Carolina way ahead of the initial delivery date. The pump runs Great and Everyone is enjoying the Pool over the Labor Day Holiday. Thank you again PST Pool Supply for your Excellent service..
Came here looking for a replacement flow switch and housing. My last one that I purchased on Amazon (cheap Chinese ****) lasted only 9mo before leaking severely in 2 places. I noticed a quality difference in the replacement I received from PST. I expect this one to far exceed the prior one. It installed quickly and works perfectly. Best of all, the leaked are gone.
