Yes, it’s usually possible to move bathroom fixtures, but it depends on your existing plumbing layout, your budget, and the structural limits of the space. Moving a sink is often the easiest since it typically only requires adjusting the supply and waste pipes. Relocating a toilet is usually more complicated, because the waste line must have proper slope and diameter to prevent blockages, and the venting system needs to be adjusted. Moving a shower falls somewhere in between—it involves re-routing water supply lines as well as the drain.
The biggest factor that affects cost and feasibility is how far the new location is from the existing plumbing stack. The closer you stay to the current lines, the less work is required, which keeps costs lower. If you plan to move fixtures across the room or to another floor, expect a more complex job that could involve opening walls, floors, or ceilings.
A licensed plumber can assess your current setup, advise on what’s possible, and provide accurate cost estimates. Sometimes, the additional expense is worth it if it helps maximize space or improve bathroom functionality, but it’s important to weigh the benefits against the cost and disruption.
