Step by Step


Step 1

Pool Shape - Round, Oval, or Custom - Confirm the shape of your pool; we stock liner for both round and oval-shaped pools. If your pool is a square, rectangle, or another non-standard pool shape, we may still be able to help you find a liner.

If your pool is not round or oval, fill out and return this custom liner form for a quote estimate of a replacement liner.

Step 2

Pool Size - Measure the width and length dimensions of your pool. If your pool is round, you’ll only need to measure the diameter. For owners of an oval pool, the pool length is measured from the curved ends, and the width is the distance between the straight sidewalls.

If your pool size is not shown on this page, fill out the customs form for a quote, or send an estimate request to Inyo’s Liner Dept at

Step 3

Wall Height - Measure your pool’s wall height from the base of the upright to the top of the pool rail. The standard sizes are 48”, 52”, and 54”.

If your pool has a deep end that extends below the base of the pool wall, you will require an expandable pool liner. These liners use an overlap style which can be installed on pools up to 72” deep.

Step 4

Liner Type - The “liner type” refers to how the liner is connected to your pool wall. The overlap folds over the top of the wall and is held in place by the top rim or a coping clip. The J-hook which has a molded lip that connects to the wall and the beaded requires a bead received to which the bead (thick edge) of the liner is slid into.

Step 5

Liner Thickness - Our liners are available in standard or heavy gauge.

Step 7

Accessories for Your Liner - Now that you've picked out your new liner, it's time to consider accessories to help with its installation and durability. Here are the most common add-ons to go with your new liner.

  • Liner Lock - acts as a wedge to prevent the bead from slipping out of the receiver.
  • Coping Clips - holds your overlap liner firmly in place
  • Wall Foam - prevent rips and or tears from over-eager swimmers
  • Liner Guard / Floor Padding - prevent liner punctures from rock, weeds, or roots from the underside of the liner
  • Pool Cove - protects against liner pinching between the pool wall and floor seam.

HDANIELS - 36 gauge is a better liner. It is more durable and will last much longer.

doglover - I wouldn't. Unless you have some way of keeping your dog from the sides, the dog will probably tear the liner.

can dogs swim in these pools without tearing the liner?

I am looking for a replacement liner for my Kayak pool, it is 16x32 with a 5 1/2 deep end. Do you carry them?

 Posted: 6/11/2011 

My above ground pool is 18 feet one way, but 33 feet 6 inches the other. Does that make it 34 feet long or am I doing something wrong? I measured at the top where the metal surround is. Could it be leaning out and I need to measure from the bottom? Also I have the overlap liner and there seems to be trim that is falling apart at the top of the pool. It is very thin, and is breaking away. Whats that for and where can I get more?

I have not heard of alternative to a vinyl liner for an above ground pool. I would strongly suggest going with a heavy gauge liner which tend to last much longer. You can click here to view Heavy Gauge Above Ground Pool liners

Has anyone ever heard of an alternative to above ground pool liners, such as fiberglass? My liner failed after 2 years and I would really like to have a longer lasting alternative to the traditional liner.
