"Depending on whether there is space under the floor and the cost is from 100 to even 300 pounds depending on the thickness and difficulty of hiding the pipe"

"Rerouting the pipework should be simple enough and shouldn't cost anymore than a few hundred pounds."

"Moving pipes under the floor is a very common part of a bathroom remodel. It makes the room look much cleaner and gives you more flexibility with where the new bath sits.Whether it’s a "quick job" or a "major headache" depends entirely on what’s under your feet.1. Can they be moved?Almost always, yes. However, the method depends on your floor type:Timber Joists (Floorboards): This is the easiest scenario. The plumber will lift the boards and notch or drill the joists to run the pipes through them. There are strict building regulations on where you can notch joists (usually only in the middle 25% of the span) to ensure the floor stays structurally sound.Concrete Floor: This is significantly more expensive and messy. The plumber will have to use a floor chaser or a jackhammer to create a trench in the concrete, lay the pipes (usually plastic-coated or protected to prevent corrosion from the screed), and then fill it back in.2. What are the costs?Prices vary based on your location and how many pipes need moving (usually a hot, a cold, and a 40mm waste pipe).TaskEstimated Cost (Labor + Parts)TimeframeTimber Floor (Relocating 2-3 pipes)£200 – £4504–8 hoursConcrete Floor (Chasing & Burying)£500 – £900+1–2 daysAdding a Waste Pipe Pump£300 – £500(Only if the new waste can't "fall" naturally)3. Key ConsiderationsThe "Fall" of the Waste: Water needs to run downhill. If you move the bath too far from the main soil stack, the waste pipe might need to stay above the floor (or be boxed in) to maintain the correct slope so it drains properly.Accessibility: Once pipes are under the floor, they are harder to reach. Most plumbers will use continuous plastic pipe (HEP2O or Speedfit) with as few joints as possible under the boards to minimize the risk of a leak.The Shower Pump (from your previous question): If you are moving pipes and you have a pump, the plumber will need to ensure the new pipe run doesn't create "air pockets" that could cause the pump to stay on or get noisy.Is it worth it?If you are already replacing the bath and the flooring, now is the only time to do it. Retrofitting this later would mean ripping up your new bathroom."

"This is definitely possible, however there are a couple of variables that could determine the cost of the job, what's currently on the floor? do the pipes need moving anywhere else other than just under the floor, the route the joists take (would they need drilling or having some of the joist removed etc
would the flooring need replacing by the person that re-routes the pipes?
either way this shouldnt cost an insane amount, id say a couple hundred"
