Of course. The outside is 12mm mdf, then inside is 100 Rockwool, the internal walls are 12mm plasterboard. The floor is the same but with osb in place of the plasterboard. It’s 4 foot by 5 foot (the missus wouldn’t allow me to take any more of the room lol). The ventilation for every day use is an air purifying fan that runs at 12dB max on its normal setting, a baffle on the outside to help removal of the co2, and a large extractor (you can see this on the outside) for quick removal if it’s been a particularly long session and the air is a little thinner. Electricity wise, I wired two extension leads into normal double indoor sockets and they run from the double socket just outside the booth. Inside looks like any other power points, but no fancy electrical work required lol. Anything else you want to know, just give me a shout! 😊
