Polynesian Low Hung Liner Pools
In addition to the more common swimming pool styles listed above, there is another form of hybrid pool called a "low hung liner" pool, popularized by Polynesian Pools over 50 years ago. The style of this pool was dubious at best, and the design never caught mass market appeal. The design, similar to other hybrid pools, used a different wall material than floor material - in this case fiberglass walls combined with a vinyl liner floor.
To accomplish a waterproof transition point from fiberglass walls to a vinyl liner floor, while underwater, required a liner retainer that is covered by a sealant tape. The sealant tape is the weak part of this design, and any person adept with leak detection knows how easily water will escape a pool system if there are any chinks in the armor, so to speak. Relying on tape for a finished water tight seal, regardless of how excellent the tape is, seems like a poor design to me. Despite this, these low hung liner hybrid pools are out there and there is not a lot of information available to owners of these pools. The information that is available seems to indicate that the sealant tape, previously offered by 3M, is either discontinued or has changed names to a new product. The closest likely product that I was able to find from 3M is their "extreme sealing tape" line which has a
4412N 80 mil tape as well as a 40 mil
4411N version. I can find no information to support that this product will work underwater in a chlorinated environment, however I was able to find information from 3M that indicates this tape can withstand high pressure washing without peeling at the edges, and has built in UV protection.
As low hung liners pools age they become harder to work on or recondition. Many of these low hung liner pool will end up being converted to full vinyl liner pools however this is not always an easy process. Over time the fiberglass walls tend to become brittle, and cracks can develop which can be a problem to resolve. The thin and relatively weak wall design also does not accept hardware very well so mounting a traditional vinyl liner coping track can prove challenging as well.
For most low hung liner pools eventually the seam between the vinyl floor and the fiberglass walls will be unable to be sealed, and leaking becomes a constant issue. It can also be challenging for owners of these pools to find people to replace the liner when it comes time as there is no easy solution - either the pool needs to be converted to a full liner pool, or the installer needs to try to work with the low hung liner design. In either case this will take much longer than simply installing a coping and liner on a vinyl pool, and this cost gets passed along to the pool owner.
Yes, we make liners for every brand of pool, but with the Polynesian low-hung pool, you have a unique opportunity. This pool originally had an acrylic pool wall like a spa and a track at the bottom of the wall so the liner could be "hung" 8 inches from the floor. Seemed like a great idea

I bought a house that has a 30 plus year old polynesian low-hung liner pool. The problem I have is hard bubbles sticking out of the fiberglass panels that sit above the liner. Does anyone know how to repair these bubbles? I will try to get pictures when it stops raining so you can see what I...
