We bought the Carron Imperial with 24 jets, light, heater, Pump Protection / Level Sensor and we Upgrade the Bath to Carronite. I am only a DIYer but had no problems doing the install after watching a few YouTube videos. Only thing I would do differently is the extra expense for the last 10 jets isn’t worth it. Although I used sound insulation around and under the bath. The air pump for the last 10 jets is loud and we don’t use it very often. I also installed a waterproof TV with an Amazon Fire Stick. WOW, she loves it and I don’t have to watch East Enders😊. thewhirlpoolbathshop.com. was more then reasonably priced, were helpful with questions and the delivery went as planned.
