Oh we do have an UTH with thermostat- we live in a cold drafty basement so without the heat lamp, the ambient temp falls way low.
Yeah we were thinking about the mesh idea- I think that honestly may just be our best bet at this point!
Oh that's an interesting idea... Are you meaning that the lamp would sit directly on the dowels or what? The lamp is already on a suspended hook ~3 inches above the tub so I don't know if dowels above the lid would work much better than the current scenario.
Thanks for the suggestions guys!!
