Hello All, I bought a house with a summerhouse (actually a log cabin workshop (pics attached), and as my garden is so small I’m thinking it might be a good place to put a hot tub
The ‘shed’ is 2.5m by 3m, has electric and I also have an outside socket (& hose for water). Shed has double doors & a window, so I’m hoping that would be sufficient ventilation (maybe with a fan in the back corner to push water out?)
My only reservation really is the floor: it’s wood, raised about 2 inches off a concrete base on joists. Will it rot? (I guess I can put down other flooring to contain drips, or install inside a paddling pool 
) and how would I know if it’s strong enough? I til the boards are 11mm tongue & groove. I called the manufacturer and they said it’s ok for eg a treadmill/motorbikes but I believe a filled hot tub would be heavier
Thinking about getting a lazy spa 4 person tub or similar (something around the £400 mark) as I suspect it won’t have heavy use : something to fit 2-3 adults is plenty, so 180cm wide would give a good 30 cm clearance all sides- and a metre & half in width to accommodate the pump etc
Does my plan seem sensible? Am I missing anything? I think I’d have bail it out with a bucket to change the water but I can cope with that (just about)
Thanks in advance for any advice
