neither buy yourself a tub from walmart, sterilite 32 qt. would be a good choice for you dont have to replace it down the road. Order yourself some pre wired flexwatt tape along with a thermostat wrap it along the the backside along with it covering a little bit of the bottomn hook up the thermostat to your flexwatt and pug it in. In my opinion those lights to do not put off enough heat, and they are impossible to keep a constant temperature. Get flexwatt asap
