I'm sure they're nice and realxing and perfectly acceptable if you live a house with a huge garden and no close neighbours nearby, but my neighbours have just bought one. We live in a row of terraces, with small gardens and are overlooked from every direction. It's slap bag in the middle of the back yard and I can actually see them sitting in it if I go upstairs.
All weekend Ive heard the constant hum from the pumps and the stench of chlorine filling the air. Now they're sitting in, shouting like they're deaf because they can't hear themselves talking over the pump.
If I'm honest I also find them a bit tacky. I can't think of anything worse. Just have a sodding bath! DB's next door neighbours have and he's been moaning about it for ages, thought he was being a killjoy until one was installed here! Now I get it.
