We've got a 70s house. No toilet downstairs. Bathroom and toilet upstairs separated by a stud wall. I'm considering knocking them together and having one big bathroom but then my husband said what if we have guests. We rarely do, so not something I'd considered.
Also the pipework where the toilet is takes up about a foot from the wall so we'd have to consider what we're doing with that.
Would you knock through or not bother?
