The decision to relocate the plumbing to the opposite wall was a no brainer for me. This allows for a wider vanity. There are not many options for layout of fixtures in this small 9 ft x 5 ft bath, so I've kept to a typical bathroom layout. And since it is the only bathroom for now, a tub is a logical choice rather than a shower. I've chosen to go with a single sink at the vanity instead of a double. A double sink would've reduced the countertop area and vanity storage. Everything is a trade-off in a small space.
