liner for birth pool in a box - have I got the right one?

[bigmouthstrikesagain]

I bought a bpiab over 2 years ago and had a homebirth - all went well.

Now I am due no.3 in October and I need a new liner for the pool - I have bought one from ebay - and it says it is a bpiab 'eco' liner. This more recent model appears to have additional handles. So will it fit my pool?

Don't want to open it as if I can return it it will obv have to remain untouched.

Is it a la bassine birth pool?

No a Birth pool in a box www.thegoodbirth.co.uk/birth_pool_in_a_box?gclid=CLCcgNflj5UCFQ9KQgodq37rgw

I found a number to call and it seems that the newer pools dimensions are substantially the same as my 06 model and the liners will still be ok. So no need to check for me

Anyone reading this there is a free phone number on the The Good Birth Co. link I attached - they are very helpful
