We live in a 4bed Victorian terrace (loft conversion is beautiful no en suite up there though and no possibility as we sided not to lose bedroom 2space to locate stairs different so we could squeeze one in), big master, small double and good sized single bedroom. Upstairs we also have a loo and sink in cupboard on landing (mains drainage not saniflo). Bathroom is downstairs and out the back in the icy cold extension. We have a towel radiator in there and electric heater but generally for 4-6 months of the year using the room is fairly miserable experience.
I debated with DH about swapping loo and sink to tiny windowless shower room by chopping out some of the master, but ventilation an issue (extractor fan would have to go through a bedroom), so only way we can get upstairs bathroom is by losing smallest bedroom (space for separate shower, loo, sink and decent sized bath.
DH is very reluctant (has been known to hint I'm a princess for wanting to shower in warmth! Humph!). We were moving but after 4.5months of being messed around by the vendors and them demanding more money we have pulled out meaning we are here for the foreseeable. We have two kids and potentially would like another though unsure at mo. Two kids currently share smallest bedroom in bunk beds which due to layout of room blocks window) loft is office (I work from home) and spare room though ultimately may need to be rejigged. (Thinking chucking kids and all their toys into loft, though not ideal as have built in double bed and bespoke desk space in eaves!)
Have checked with estate agents and they think will make it easier to sell in future, it shouldn't affect value but we are almost at limit of what we have spent on house that we will ever get back so need to be careful what we spend, as the plumbing is in place it shouldn't be too horrific but will need building regs sign off (which we didn't get for loo and sink which may cause issue!)
Would either convert the upstairs loo cupboard into a small walk in wardrobe (for loft bedroom users as wardrobes tricky up there due to head height) or a tiny office for me (windowless though), then my plan might be to turn the small downstairs bathroom into a downstairs shower room with loo, sink and shower and loads of utility space and dirty laundry sorting cuboards etc. but may leave for now as costs and getting carried away.
Ultimately this was never supposed to be our forever house and have already been here two years longer than expected but now my best friend lives across the street and we are in and out of each other's houses and our kids are best mates and we are 5min walk to primary school so for the next 6 years I can live here until kids are teens and think we will grow out of it (tiny galley kitchen) especially if we have three. We just can't face going through more stress like last few months have been when we were moving.
Sorry for long post- trying to give all relevant info. Can you help me decide what to do for the best and give me some statements to help convince DH upstairs bathroom is good idea. :)
