On a Round pool, simply get a measuring tape and take 2 measurements. Go from
the inside of the pool at the bottom of the wall and measure directly across to
the other side at the same height. Do this in two locations in the pool and make
sure you get the same measurement. We like to measure at the bottom of the wall
in case the wall is not plumb from side to side. The wall at the bottom track
location is your safest bet.
On an Oval pool you do the same thing as a round except that you do it in the
middle of the pool from side to side and at the ends at the longest point from
end to end. All measurements are from inside the pool touching the wall at the
Measuring the Depth of the pool
The depth of the pool can range from 48" to 54" deep. Most liners are either 48",
52" or 54" Deep. Manufacturers also make provisions for the dirt, sand wedge, or
pool cove that is needed at the base perimeter inside the pool. If your pool has
water in it measure out at least 2 ft. from the sidewall with a measuring tape
to the point at the top of the wall or where the liner is attached. Bear in mind
that most round liners are made to be flat bottom and not a deeper middle. If
your pool has a deeper area you will need a special expandable liner. Do not buy
one of the liners we have listed. They are not expandable liners.
Some liners are what we call overlap. This type is the most common and simply
folds over the corrugated metal wall and drapes down on the outside of the wall.
The liner is held in place by plastic coping strips. You may wish to replace
these if your old ones are brittle and dry.
Beaded liners have a thick-formed extrusion at the top that hooks into a female
receptor (Bead Receiver) around the top of the pool wall on the waterside. Most
pools can utilize the standard bead that is common in the industry. Call us if
you feel you need more assistance. Incidentally, you can change your overlap
liner to accept a beaded liner by simply adding bead receiver strips to the
order. This way, if you need to change the liner in the future, you do not have
to remove the top seats of the pool. This is a real timesaver and is much easier
J-Hook-V-Bead are liner types that have a thicker open flap top that inserts
over the corrugated metal wall. It looks likes the plastic coping we use to hold
an overlap liner over the metal wall except that, in this case, it is attached
to the top of the liner. If you are using an overlap liner and your pool is a
flat-bottom, you can use the V-Hook or the J-Hook type liner.
Unibead liners are quickly becoming the most popular type of liner because it is
a combination of the Beaded and the J-Hook Liner. You can use this type of liner
either way. Poolandspa.com does not sell Beaded and J-hook Liners.
We sell the Unibead liner. We recommend using it as
a J-Hook. This way, you do not have to purchase any additional items to install
the liner. Simply hang the liner onto your pool wall with the embedded J-Hook on
the back of the liner. There are some situations where you may want to use it as
a Beaded liner. In this case you will need to purchase the correct amount of "Bead
If you have an Overlap liner you can change it to a Unibead liner, No Problem.
You do not have to get another overlap liner. Just purchase a Unibead liner and
Hang it from your pool wall.
