our house is a walk-outSparteye, what is a walk-out? Oh, unlike your neighbours who have drive-ins, jump-offs, fall-outs, etc. ?????
I have a bathroom which has a bath (it would not be a bathroom in UK without one) and a basin/sink, bidet, toilet/loo and the water comes out of taps, the hot having been heated by the boiler. We also have a downstairs cloakroom with a toilet and sink, and incidentally the stopcock. The kitchen has a sink and a draining board. No one in UK has a faucet that I know off (Though we do have a pub in Fawcett Road with the name Fawcett Inn

)
We have very few fire hydrants in UK. In Swiss viallges, they are common because of the wooden chalets, but they are often painted as little men; a waiter outside the cafe, a soldier, etc.
Quiet a few houses in Portsmouth have basements which are habitable half underground levels, and some have cellars, usually completely underground and storage (for spiders).
