Remember the difficulty with the bathroom? Its main problem was the small size. It took us a great deal of engineering thought to allocate everything conveniently, aesthetically, and within budget all in one. The solution came in shape of an installation built-in the brick wall.
Although a shower-stall would have saved quite a bit of space, we eventually settled for a bath – it's more practical, more popular among tenants, and generally cheaper than a stall.
