In the process of refurbishing a house. On the first floor there is a decent size cupboard which looks ideal to house a shower. The main bathroom is behind so hot, cold, and waste are close by. Wondering which type of cubicle i need to fit this space. The width is exactly 76cms and the length is approx 7 1/2 feet, so bit like a long corridor. Shower door would obviously have to open outwards from the front. Walls will be tiled on the three sides.
