It's a gas fire pit, no maintenace, the cover lift came with the spa not sure what brand it is, it has a hydraulic shock in the back to aid in lifting, works great.
You can't see the B&W AW-6 speakers under the eve's they plug into the reciever in the house so you get full fidelity while yer soaking, BLESSED, yes.
My wife and I love absolutely love this spa, Wow!! this thing has got some power, I don't just mean jet power, it's Magic.
It removes all sorts of aches and pains and it make you go AAAAAAAHHHHHH and smile every time you get in.
Thanks again everyone
