Trilogy Casini vs G36 Rectangular Fiberglass Pool Comparison

The fact that you’ve found this article means you are probably well into the process of finding the right pool for your family.

Maybe you have already decided that a fiberglass pool is the way to go, and possibly that a rectangular shape is best for you….now it’s just a matter of finding the pool design that meets your needs the best.

If this is the case, you’re in luck because today we’re going to compare two of the most popular rectangular fiberglass pools on the market: The Casini by Trilogy Pools and The G36 by our company, River Pools.

You’re probably wondering how, as a manufacturer, we can possibly give an unbiased comparison. The truth is that we can’t.

We are very passionate about what we do and we love our product...heck, that’s the way it should be!

Notwithstanding, we can provide you with straight information about the two designs and explain why we designed ours the way we did…then let you decide. Sound fair? Great, let’s get started!

First we’re going to discuss what the Casini and the G36 have in common, and then we’ll cover the differences between the two pools.

Common Features

Both pools are rectangular in shape and exactly 16’x36’ in size.

The depth of the pools is also very similar with the Casini at 3’9” to 5’4” and the G36 at 3’8” to 5’6”.

Differences Between the Casini and the G36

Step Location and Layout

The Casini has a single set of “wedding cake” steps coming from one corner of the shallow end that extend five feet toward the middle of the pool.

The G36 has dual steps coming from both shallow end corners that extend out toward the center of the pool two feet and lead down both sides of the pool.

In designing the step layout of the G36 we felt two sets of steps would allow more flexibility for positioning the pool in the yard, plus we knew we wanted a symmetrical design.

Bench Location and Layout

The Casini has a single bench seat along the entire deep end wall that is eighteen inches wide.

The G36 has an arched bench seat across the shallow end that is two feet wide narrowing to one foot wide in the center. It also has small bench seats in the deep end corners.

Considering that most pools have patio space adjacent to the shallow end of the pool, we felt that a shallow end bench would serve several purposes.

First, it would allow parents to sit close to their smaller children (who usually hang out on the bench seats).

Second, for the most part, when people play games in a pool (assuming the pool isn’t too deep), they play in the middle to deep portion of the pool.

Basically, the shallow end is for hanging out and the rest of the pool is for goofing off…at least that’s our experience.

The two deep end seats in the G36 are just large enough to fit two adults. We kept them very small so they wouldn't intrude into the open swim/play area.

Pool Floor Surface

The floor of the G36 is textured and the floor of the Casini is not.

Although we have found that fiberglass pools are not slippery, regardless of the texture of the floor surface, we understand that this is a concern for people so we decided to add texture to the G36 floor.

Safety/Convenience Ledge

A safety ledge is a three inch wide ledge, about two feet down from the top of the pool. The G36 has one and the Casini does not.

This ledge does provide a means for children to rest while hanging on to the side of the pool. Adults can also prop their knee against it while holding the pool coping.

On a personal level, I was shocked at how my 3-year-old son Daniel used the safety ledge to help him learn to swim. Check out the following video to see for yourself.
