Morning all bathroom lovers, I'm sectioning off part of bedroom to create separate, not en suite, new bathroom. Should I build my stud wall first and then squeeze sanitary units in? Thought that fitting toilet, basin and bath first might be easier option. Then I build my wall and door around them. I'm planning to cram a slim toilet as close as possible to small basin, shunted up to 1700 shower bath. Door opposite sink and basin. Has anyone got any hard won experience on this?
