Do Fiberglass Pools Need Liners? Complete Guide

Called three different pool companies this year about whether my fiberglass pool needs a liner and got three different answers—I'm done with the confusion. With vinyl pools, I understand you need a liner that eventually needs replacement every 8-10 years. But what about fiberglass pools - do they also require some type of liner system to hold the water?

I'm specifically looking at installing a 16x32 fiberglass pool (approximately 24,000 gallons) and want to understand all the long-term maintenance requirements. The sales rep mentioned something about a gelcoat surface, but I want to make sure I'm not missing any liner costs in my budget planning. Do fiberglass pools need liners installed, or is the structure itself sufficient to contain the water without additional waterproofing materials?…more

Do Fiberglass Pools Need Calcium Hardness? Complete Guide

Pool builder says my new fiberglass shell doesn't need calcium hardness adjustments like a plaster pool does. But the water test shows 150 ppm and the internet says that's too low for any pool. Who's right here — does fiberglass actually need calcium or not?…more

Do All Pools Need Liners? Pool Types and Liner Requirements

During my pool consultation, three different contractors gave me completely opposite answers about needing a liner, and now I'm wondering if someone's trying to upsell me.

I'm considering several options including above-ground pools, concrete inground pools, fiberglass shells, and even looked into natural swimming pools. Some contractors are telling me that every pool needs a liner, while others say certain types don't require them at all. I want to make sure I understand the liner requirements before making my final decision, especially since this affects both the initial cost and long-term maintenance.

Can someone break down which specific pool types actually need liners versus which ones can function without traditional vinyl liners? I'd appreciate any insight into how the construction material affects liner requirements.…more

Do Inground Pools Need Liners? Complete Guide 2026

Wondering if my pool renovation is draining my savings account because I keep second-guessing whether my inground pool actually needs a liner. My neighbor just had to replace his pool liner after like 10 years and it was a huge hassle, but my other friend says her concrete pool doesn't have a liner at all?

So which types of inground pools actually need liners and which ones don't? And if I do end up with one that needs a liner, how often am I looking at replacing the thing? Trying to figure out the long-term maintenance costs before I commit to anything!…more

Do Saltwater Pools Need Calcium? Complete Guide to CH Levels

Tried everything I can think of, but why does my saltwater pool keep destroying my salt cell and corroding my heater elements while making the surface look rough? I've been obsessing over chlorine and pH levels, but maybe I'm missing something obvious?

A friend mentioned calcium hardness might be the culprit, but I honestly have no idea what levels saltwater pools need. I know regular pools need calcium, but does the salt system change things? And if my calcium is off, could that really be why my expensive equipment keeps failing? I'm hoping there's a simple fix here because I'm tired of replacing parts every few months.…more
