We do not recommend to cover your surfer as it is designed to be left on 24/7 using the aroma top.
But, if you want to change the look of your surfer you can absolutely do that by putting a sticker on the housing. If you want to remove the sticker later you can do that easily and with a little alcohol, the sticky will come right off.
If you have a unit and you really want to change the look, you can get new housing to replace the housing of your unit. We are happy to do that for you if you send it into us for only $10 to cover labor. You will also have to purchase a new housing and they can vary in price.
