We are in the middle of revamping our garden and considering one of those "Lay-Z" hot tubs. Bit worried about the noise of them, so thinking about enclosing it. We have a pergola frame and thinking of putting that up but enclosing it with wood on 3 sides (so front is open to garden) which may help drown out some of the noise from escaping? What sort of wood would (EDWARD WOODWARD!) be best to use to make something like that? (remember, have the wood framework, its just the sides). Over to you DIY experts!
