The plumbing fixture may be any plumbing fixture known in the art but is preferably a faucet and/or a showerhead. Different embodiments may feature multiple indicator strips or may be finished with a thermochromic coating. In this manner, the device, or portions of the device, may change color as the temperature of the water heats up the thermochromic coating, which results in a user obtaining information about the water's temperature. ## Claims ### Claim 1 A thermochromic plumbing fixture device further comprised of: a plumbing fixture; and at least one indicator strip comprising an adhesive backing; and wherein the at least one indicator strip is coated with a plurality of thermochromic elements, each thermochromic element configured to react to a different temperature range from the other thermochromic elements and causes the at least one indicator strip to change color based on a temperature of a water passing through the plumbing fixture, wherein the at least one indicator strip is adhesively applied to the plumbing fixture. ### Claim 2 (depends on 1) The thermochromic plumbing fixture device of claim 1, wherein the at least one indicator strip is located on a body of the plumbing fixture. ### Claim 3 (depends on 1) The thermochromic plumbing fixture device of claim 1, wherein the at least one indicator strip changes from a first color to a second color when the temperature of the water within the plumbing fixture reaches 88 degrees Fahrenheit. ### Claim 4 (depends on 1) The thermochromic plumbing fixture device of claim 1, wherein the at least one indicator strip displays a first color if the temperature of the water passing through the plumbing fixture is below 60 degrees Fahrenheit, and displays a second color if the temperature of the water passing through the plumbing fixture is between 61 and 80 degrees Fahrenheit, and displays a third color if the temperature of the water passing through the plumbing fixture is between 81 and 100 degrees Fahrenheit, and displays a fourth color if the temperature of the water passing through the plumbing fixture is above 100 degrees Fahrenheit. ### Claim 5 (depends on 1) The thermochromic plumbing fixture device of claim 1, wherein the plumbing fixture is a showerhead. ### Claim 6 (depends on 1) The thermochromic plumbing fixture device of claim 1, wherein the at least one indicator strip comprises a decorative indicia. ### Claim 7 (depends on 1) The thermochromic plumbing fixture device of claim 1, wherein the plumbing fixture is a faucet. ### Claim 8 A thermochromic plumbing fixture device further comprised of: a plumbing fixture comprising an escutcheon plate, a pair of handles, a spout, a stopper, and a meshed aerator; and at least one coating of a thermochromic paint that has heat-sensitive properties that causes the at least one coating to change color based on a temperature of a water passing through the plumbing fixture, wherein the at least one coating can be applied to any component of the plumbing fixture; and at least one indicator strip embedded within the plumbing fixture and comprising a plurality of thermochromic elements, each thermochromic element configured to react to a different temperature range from the other thermochromic elements and cause the at least one indicator strip to change color based on a temperature of a water passing through the plumbing fixture. ### Claim 9 (depends on 8) The thermochromic plumbing fixture device of claim 8, wherein the at least one coating is located on a body of the plumbing fixture. ### Claim 10 (depends on 9) The thermochromic plumbing fixture device of claim 9, wherein the at least one coating changes from a first color to a second color when the temperature of the water within the plumbing fixture reaches 88 degrees Fahrenheit. ### Claim 11 (depends on 9) The thermochromic plumbing fixture device of claim 9, wherein the at least one coating displays a first color if the temperature of the water passing through the plumbing fixture is below 60 degrees Fahrenheit, displays a second color if the temperature of the water passing through the plumbing fixture is between 61 and 80 degrees Fahrenheit, displays a third color if the temperature of the water passing through the plumbing fixture is between 81 and 100 degrees Fahrenheit, and displays a fourth color if the temperature of the water passing through the plumbing fixture is above 100 degrees Fahrenheit. ### Claim 12 (depends on 8) The thermochromic plumbing fixture device of claim 8, wherein the plumbing fixture is either a faucet or a showerhead. ### Claim 13 (depends on 8) The thermochromic plumbing fixture device of claim 8, wherein the at least one coating further comprises a decorative indicia. ### Claim 14 (depends on 13) The thermochromic plumbing fixture device of claim 13, wherein the decorative indicia resembles a flame. ### Claim 15 A thermochromic plumbing fixture device further comprised of: a plumbing fixture; at least one coating of a thermochromic paint that has heat-sensitive properties that causes the at least one coating to change color based on a temperature of a water passing through the plumbing fixture, wherein the at least one coating can be applied to any component of the plumbing fixture; and at least one indicator strip comprising an adhesive backing and a plurality of thermochromic elements, each thermochromic element configured to react to a different temperature range from the other thermochromic elements and cause the at least one indicator strip to change color based on a temperature of a water passing through the plumbing fixture, wherein the at least one indicator strip is adhesively applied to the plumbing fixture; and a plurality of color-changing symbol indicia for indicating specific temperatures. ### Claim 16 (depends on 15) The thermochromic plumbing fixture device of claim 15, wherein the at least one indicator strip is located on a body of the plumbing fixture. ### Claim 17 (depends on 16) The thermochromic plumbing fixture device of claim 16, wherein the at least one indicator strip changes from a first color to a second color when the temperature of the water within the plumbing fixture reaches 88 degrees Fahrenheit. ### Claim 18 (depends on 16) The thermochromic plumbing fixture device of claim 16, wherein the at least one indicator strip displays a first color if the temperature of the water passing through the plumbing fixture is below 60 degrees Fahrenheit, displays a second color if the temperature of the water passing through the plumbing fixture is between 61 and 80 degrees Fahrenheit, displays a third color if the temperature of the water passing through the plumbing fixture is between 81 and 100 degrees Fahrenheit, and a fourth color if the temperature of the water passing through the plumbing fixture is above 100 degrees Fahrenheit. ### Claim 19 (depends on 15) The thermochromic plumbing fixture device of claim 15, wherein the plumbing fixture is a faucet. ### Claim 20 (depends on 19) The thermochromic plumbing fixture device of claim 19, wherein the plumbing fixture is a showerhead.
