I had the same problem in my old house in Ainsdale. It was one of those Lion claw cast iron baths almost 2m long. It took an age to fill and being cast iron it lost heat quickly. I put it in the classified ads in Country Living for £1000 and it sold the first day the magazine came out. It took 6 men to get it out of the house. If I had 30 of them I could have sold them all. The phone didnt stop ringing for weeks.
A grand for an old bath, reminds me of this.
