My master bathroom has a triangular corner jacuzzi bathtub which I’ve come to realize is lacking insulation along the lower exterior walls behind the tub. As a result, the bathroom and bedroom get pretty cold. I do not have access to most of the uninsulated wall sections and I would prefer not to have to rip out my tub to have it insulated. The house is 7 years old and came with a warranty, although I’m sure filing a claim will be a bigger headache than its worth. Is there a simple way to effectively insulate behind the tub or will I need to tear it out?

Drill thru the exterior wall? Foam it? Blow it in thru the drain access area? 1 st or second floor? basement access? Cut a hole in the drywall and refinish it?
Info please.
Do you have an access door to get to the pump? Cover the pump/motor and blow in insulation.
There are two access panels although they are both in the front of the tub and do not allow easy access to the exterior walls. I considered blowing in insulation, although I wasn't sure how to keep it up against the walls as I can't get in behind the tub to add some blocking. Foam was also a consideration, but I was worried that the foam might leach into the motor and jets. If all I have to worry about is the pump I might be able to just blow enough insulation in to cover the back of the tub. Would getting someone in to apply foam to such a small space be expensive?
Cover the motor and have at it. Keep it clear of insulation. The spray foam may cause more problems as it expands and could stress something unseen.
Look behind the tub by using a mirror and a flashlight. You'll answer lots of your own questions by doing that. I suspect the wall is already insulated.
