joiner, if the main floorboards under the bath are ok where the bath fits no need to cover, the plaster board at side of bath needs to be replaced with something called aqua board i think its called its a water repellent board made for wet rooms, showers etc can be plastered over and then tile it to keep water off the wall, and dont forget to seal around bath wih silicone, when you seal the bath make sure bath edge is dry, fill bath with water seal around bath and leave overnight to dry it will be sealed silicone is flexible so slight movemet on bath will notbreak the seal
