The 8 Best Thermostat adapter plates (2023 reviews)

This base is technically the first step on installing the new thermostat. It gives a great look to the Nest Thermostat. The top and bottom curves starts around 3 1/4" on the top and bottom, and being only about 5" wide (top to bottom), your rectangle will be too large to cover.

Putting these plates on is straightforward, they are a perfect match for the Nest mounting plate and lock onto it. The plate is a bit thinner than preferred so it does have a little bow in it. It can use the same attachment holes for the screws for the plate. The plate cover fits great and covers all old thermostat marks.

Why We Like This:

Makes it look better, covers holes by old thermostats
Really completes the look of the new thermostat
Easy to install, covered worn / damage area
Fits perfectly to the nest thermostat
