Hi, thanks for the question. This in-ground spa is built in the same fashion as an in-ground swimming pool. The equipment is nearby in the yard.

Is there a cover to keep the heat in in the cooler tempertures? Is it easy to put on and take off?

Thank you for your interest in our project. An automatic cover is installed on this spa. The vinyl cover runs on track under the pool coping. It retracts into a vault under the patio when it is open. The cover helps with temperature control as well as safety.
