I seem to have spent a goodly part of the past fifty plus years putting in toilets in houses I have lived in.
In 1964 we purchased our first house when we got married. A Victorian house with an outside toilet. People before us had used part of the back bedroom to install a bathroom, large room and eventually we also put a toilet in there. Access was via the back bedroom, but it did gives us two loos.
Only stayed in the next house for four years, a new build with a downstairs cloakroom and bathroom upstairs. Grew out of this when our twins were born and moved to a much larger 1920's house, four good sized bedrooms, but just one toilet, next door to the bathroom. With young children we had a second toilet installed into that bathroom. Several years later, we divided the large back reception room downstairs and turned that into a room containing a loo, shower, etc. and room for washing machine.
Left there to come to present 1930's house. One toilet in bathroom, second loo downstairs in little more than a cupboard (had been the old outside toilet, turned round so entry was now from indoors, (just). Had that modernised and even managed to install tiny washbasin in there.
Only me in this house, but I had always wanted an en=suite - mainly to give me a separate shower cubicle (the one I had was over the bath). When I had the loft made into a bedroom for g.children, used the new under stairs place for this en-suite.
My kids laughed at me, 'Why?' they asked, 'did I need three toilets, when only I lived there?' But all three had their used and place.
Hoping to move soon to a flat with just one toilet in the very nice, modern shower room. No place to put any others, so will bring that phase of my life to an end. Four houses between 1964 and 2019 and have installed five loos
