What you might get
Better fixtures, like a toilet with better flushing capabilities or faucets with better flow. New features like flooring, a vanity, a sink, lighting, window treatments, hardware, a comfort-height toilet, a framed mirror that matches the vanity or recessed medicine chest—all of which are slightly better quality than from a big-box store. Plus, you can make a few more adjustments to the layout. Maybe you’ll put in a slightly smaller bathtub to make way for a slightly larger shower. Maybe you’ll slide a sink down and move the plumbing slightly to add a tall linen cabinet.
A higher-grade granite, marble, or quartz.
Semi-custom pieces with higher-end finishes—glazed instead of just stained, and decorative details like cabinet legs and intricate door panels.
You can make moderate adjustments to the plumbing, like moving the faucets or shower, but the toilet will likely stay in the same relative location.
You can upgrade the fixtures for ones with higher-quality copper or bronze inside, which will last considerably longer than off-the-shelf units.
At this level porcelain will be your new best friend. It’s more durable than ceramic and slip-resistant, and there are more color, size, and design options. Porcelain tiles are designed to mimic natural stone.
You can get a bit more creative with materials and do tile walls or real beadboard.
