During our master bathroom remodel I came across multiple posts about needing to insulate the underside of bathtubs. I never realize there wasn't insulation under tubs and it makes sense that it needs to be insulated, otherwise the water will get cold by the time it fills up. I considered spray foam but some discussions said when the foam expands it can't change the shape of the tub. I came across these and decided it was worth a shot. I used 3 of them to wrap the underside of the tub. It was relatively easy to do, just use lots of duct tape! I haven't taken a bath yet but feel better knowing I did what I could to insulate before the tub was set in place.
