If the weather outside is not suitable for drying, I drape my heavy laundry like towels etc over the towel rail/ radiator in the bathroom, and hang the rest on my excellent roll-away Tidy Dry two line washing line which extends out along the length of the bath and is fastened to the wall at either end. I don't know whether you can still get them, but they used to be available with two or four lines and they simply roll themselves back into the wall after use, rather like the cord on the vacuum cleaner sucks itself away in the body of the cleaner when you have finished with it. I do have a tumble dryer but rarely use it.
