hi judi, reckon from what you have told me that the cost would be between €4200-€4800. hard to give a specific price as you can understand. i have seen some terrible resurfacing jobs. they cost €180-€280. you can buy a basic bath around €100. cast iron is a lot colder, longer to heat, and easier to stain and chip, totally a personal choice of course, but my opinion would not favour resurfacing.please pm me for additional info
